CEO'S MESSAGE

A JOURNEY OF WELL-BEING AND GROWTH

Dear Supreme Energy Family,

Our journey is not just about reaching the destination, but it is also about enjoying the ride, maintaining balance, and ensuring that our minds and bodies are well-prepared for the journey ahead

Due to our fast-paced and busy schedule, we give less importance to physical fitness and mental health As a result, all we have become is physically inactive and lazy Also, we are more addicted to eating more and ordering food from outside Therefore, this has given rise to several diseases starting from cardiovascular diseases, obesity, depression and anxiety Although there have been several medical technologies and treatments that can get you out of it, all it takes to stop this thing is self-control and a healthy lifestyle We can only enjoy all the valuables of life if we are physically and mentally healthy The health of an individual plays a major role in his/her/their life and must be taken care of The health awareness as well as ensuring lifetime learning and improvement are parts of Supreme Energy’s values

In spite of our busy schedules, it is our responsibility to prioritize our health and involve ourselves in some kind of physical activity Physical exercises need not be always strenuous, it can also be done in the form of walking, cycling, yoga and meditation that brings calmness to both mind and body

However, it is not enough Most of the role to keep us healthy is played by the food we intake It will be of no use if we intake unhealthy food, rich in sugar and cholesterol levels and try to be healthy Apart from exercising, it is equally important to drink plenty of water to keep ourselves hydrated The level of fitness totally depends on the amount of activity our body can perform and the food we consume Thus, inculcating a habit of eating healthy foods such as fruits, green vegetables and essential vitamins is really important

During this year independence day’s celebration in August 2024, we have conducted some sport activities and games as well as the first family gathering during the fun walk I hope this was really helpful in motivating all of us to stay physically and mentally healthy So, it is high time that we really put our health over everything and take proper care of it I would like to thank all of you for participating the activities

We are currently facing challenging times We have yet to commence the development of the Muara Laboh Unit-2 Project as we await tariff approval from the Minister of Energy and Mineral Resources At Rantau Dedap, the shareholders have to invest additional USD 80 million to recover steam productivity at the same original capacity Meanwhile, exploration at Rajabasa is still on hold, awaiting the signing of the PPA Amendment, delaying the start of the project further Despite these challenges,

I firmly believe that with a good intention and effort to contribute to Indonesia’s energy transformation, along with strong prayers and relentless efforts, we will overcome these challenges Together, let us ensure that our journey is not just about achieving great things but also about enjoying the ride with a sense of fulfillment, purpose, and happiness

Stay safe, healthy and happy

Warm regards,

EMBRACING THE UNKNOWN: HARDINALD ASLAM'S LESSONS FROM TRAVELING

By: Meidina Dwisavira

The thrill of taking to the skies! As a child, I would gaze up at the clouds, mesmerized by the contrails crisscrossing the blue expanse, my imagination soaring alongside Anytime I saw a plane, I felt a rush of excitement My dad, who frequently traveled, took me along with him out of town That was my childhood dream: to become a pilot, to soar through the skies and explore the world

But life had other plans. As I entered high school, my eyesight began to falter, and I had to trade in my flight suit for glasses. My dreams of taking to the skies seemed to take a nosedive. Yet, fate had a way of repurposing my passion for travel. My job allowed me to fly frequently, which satisfied my passion for traveling.

It was then that I met friends who shared my love for travel and photography, mainly going to the hidden gems of the world We often traveled together traversing the globe, camera in hand, capturing the beauty of far-off lands My favorite destinations are places with deep historical roots and spectacular scenery, so Turkey is one of my tops list – its ancient cities, rich history, and vibrant markets beckoning us back time and again Mardin, a city on the border of Turkey & Syria, with its magnificent ancient architecture, nearby Tigris river left footmark of the human history since the 4th century, held a special place in my heart

Indonesia also offers numerous beautiful travel destinations with stunning scenery and exotic locations Exploring remote villages in Flores where residents still wear traditional clothing and chew betel nut is truly a delight The rugged beauty of Ramang-ramang, the crystal-clear waters of Belitung – each destination left me awestruck

Meteora - Yunani

Desa Wologai , Flores. Kampung Adat berusia 800 tahun

And yet, it’s the unexpected moments that make my journeys truly unforgettable: the interactions with locals in their native language, leading to hilarious misunderstandings; chatting with strangers who become friends; and seeing people practicing different cultures These experiences transport me to another world whether I’m getting lost in the winding alleys of Istanbul, discovering hidden gems, or being invited to dinner by a shop owner whose wife is from Indonesia

BUT EVEN WITH ALL ITS THRILLS AND SPILLS, TRAVEL CAN BE UNPREDICTABLE.

Like the time I ventured to Iceland during its darkest winter months, only to find myself confined to my hotel room due to subzero temperatures, which derailed my plan to photograph the aurora Or the trip to Nepal during a national strike in 2010, when demonstrations and sirens filled the streets Such moments tested our resolve and forced us to adapt

And then witnessing murder in Oxford street of London in the mid-day of 2006 has given me one of the most scariest moment in my life

Today, I've traversed to many parts of the world, except Latin America From watching public cremation in Nepal to lost in alley of the market in Marrakech, from stuck in the rich history of Uzbekistan to get the feeling of the footprint of Sovyet Union in Georgia, from the dangerous part of Cape Town to the secretly beautiful Philippines in Batanes island Cuba remains on my bucket list – its unique heritage waiting to be explored I haven't found the right time to fly there yet, as it's a long flight and I would need a longer leave period Perhaps I'll save it for after I retire Until then, my biggest dream now is to launch the Travel Photography album

Istanbul - Turkey

TRAVEL IS LIFE'S GREATEST TEACHER – FULL OF SURPRISES, TWISTS AND TURNS.

It's a journey that requires resilience, adaptability, and an open heart And for me, it's a balm for my soul – restoring my energy and inspiring me to take on new challenges when I return to my daily routine

So if you ever spot me gazing up at those clouds again, know that my spirit is still soaring – even if my physical form may not be quite as agile as it once was For in the world of travel, every moment is an opportunity for adventure – and every mile flown is a chance to rediscover myself anew

LEAD STORY NOVI GANEFIANTO PROFILE INTERVIEW

By: Dayinta Adi Dyaksa

EMBRACING THE UNEXPECTED: NOVI GANEFIANTO

As I write this article, I am already reflecting on its main message; that life is full of unexpected twists it can be incredibly sweet or the most unwelcome bitterness I used to read Mitch Albom’s novel his stories often revolve around seemingly ordinary characters living average lives, only to reveal that they’ve been actually leading incredibly meaningful lives all along It’s like finding out that your plain old cereal box has a secret compartment full of gold While life might not always seem to favor everyone, it’s often packed with surprising turns

Meet Novi Ganefianto, he’s been Vice President of Exploration and Subsurface Engineering in Supreme Energy since 2015 He stepped in during a challenging time for the company after Muara Laboh and Rantau Dedap exploration drilling and readers, if you remember, it was one of those times when we had to say goodbye to some of our team members Since then, under his leadership, the team has thrived under pressure Having been on his team myself, I learned that embracing the unexpected is the name of the game

LESS-THAN-STELLAR COLLEGE LIFE

Novi was born in Bandung but moved to Jakarta at the age of 7 Growing up in a Betawi environment, he was used to Betawi’s culture where neighborhood gatherings and communal activities are the norm His role model, his mother, fully embraced this way of life as well She was known for making homemade dishes for Novi’s friends who came over, truly embodying the spirit of hospitality and community that defined their Betawi upbringing This social background likely honed his intuitive skills as a field geologist in the future

Back in 1983 before his college days, Novi excelled in his early education, showing a particular flair for chemistry, mathematics, and Bahasa However, his college years in Teknik Geologi-Institut Teknologi Bandung (ITB), presented a different challenge Struggling academically, he found solace and escape in music and soccer He even made some songs that are still sung to this day by Teknik Geologi ITB’s students During that era, the oil industry was highly desirable among students

As a result, many students aimed to work in the oil field, giving the industry ample opportunities to filter and select the most talented individuals

Novi was never been one of them He took another “field” that was far from mainstream and much less popular: gold mining Readers, as a geologist, I want you to know that gold mining is one of the toughest fields out there It turns out that because gold mining was less popular, he became one of the most reliable young experts in the field He started getting a lot of projects, and it seemed like everyone suddenly took notice of him This journey ultimately led him to the field of geothermal energy Given that geothermal work is related to gold deposits, he likely picked up some geothermal knowledge along the way, even if unconsciously

YOUNG NOVI DISCOVERED RANTAU DEDAP

In 1992, he joined UNOCAL Geothermal at the Salak Geothermal Field The job demanded a lot of fieldworks, he even hand-carry motorcycle during this era This was a stark contrast to his teenage adventure in 1982, when he traveled to Bali with just 24,000 rupiahs and a friend That trip, which included a game of cat-andmouse with the train conductor, stretched over ten days they spent six days traveling, with four of those days eating whatever they could afford, and wrapped up their risky-adventure with a “glorious” New Year’s celebration in Bali Given that experience, hand-carrying a motorcycle probably seemed like a walk in the park by comparison

One day, Novi encountered a local old man who was the only one to mention the presence of fumaroles The next morning, Novi and the old man embarked on a journey together and successfully discovered the fumarole No one ever mentioned that Novi was the one who named the field Rantau Dedap the field was named after the nearby village The fieldworks resulted in Lumut Balai and Rantau Dedap as one prospect geothermal field called Ringgit Block

In the same year, he had opportunity to explore South Sumatera, frequently visited Desa Bandar Alam, conducted geological survey using old-school methods like air photos and chatting with locals (no drones or fancy tech here), they uncovered potential geothermal sites in Lumut Balai

The fieldwork project then extended due to the team's curiosity to explore more in nearby location Novi was once again entrusted with locating the thermal manifestation to undiscovered area nearby Relying on communication with local people, asking whether they had ever seen any gumorah fumarole It was like finding a needle in a haystack if the haystack was made of dense jungle The locals he met always said, “no gumorah here ” Sounds very discouraging situation

THE TABLES HAVE TURNED

After just a year of dodging mud and rocks, in 1993 he was sent to Auckland University in New Zealand to get his diploma’s degree in Geothermal Exploration and Development Technology This was a major plot twist in his life story He redeemed his earlier college struggles by snagging the title of The Best Earth Science Student

Returned to Indonesia in 1998, during the economic crisis, all UNOCAL’s projects are halted He was then assigned as Manager of Environment and External Affairs in 1999 During this period, he joined the API as a board member He frequently met with the Minister of Environment and was chosen as a delegate for the Indonesian government at the UNFCCC (United Nation Framework Convention on Climate Change) in 2002 By then, he had traveled to 12 countries, took role during COP 8 (pre - Kyoto Protocol) and introduced geothermal energy to global discussions, helped establish geothermal energy as eligible for carbon credits

In 2004, Chevron Texaco acquired UNOCAL and Novi was “confidently” getting ready to get fired but then he was retained as Geoscience Manager for Chevron Geothermal in Indonesia became the first Indonesian to held such position in Chevron Life is full of surprised, isn’t it

“Sometimes we misjudge ourselves and others see us differently,” Novi said during the interview

His journey continued, his career remain at steady state In 2010, he flew back to New Zealand to a small city called Rotorua, where he worked as a Geoscience Manager at Mighty River Power Four years later, he took on the role of Country Manager at Thermochem He encountered some obstacles as he stepped out of his comfort zone

THE ART OF MAYBE

In 2015, he joined Supreme Energy and played a key role during the Muara Laboh development drilling His personal highest achievement was the development of Muara Laboh Unit 1 Alongside this, he was deeply involved in the Rantau Dedap development, the commissioning (COD), and continued to work on the Rajabasa project Despite his significant achievements, he remains a modest leader, always crediting his team for their collective success

“Don’t worry if your work isn’t perfect, because every task, no matter what it is, serves as a platform for discussion Every idea is valuable ”

“There’s always uncertainty with subsurface work,” he implies about working in geoscience, “It’s like driving; we constantly face decisions about whether to go left or right, and no one can predict exactly what will happen at the edge of the road ”

He sees growth opportunities for Supreme Energy, not only supported by the good character of its employees but also by the potential of its geothermal fields He envisions a future where skilled individuals from the nation remain actively involved, and young people continuously learn and deepen their understanding of Indonesia’s geothermal resources, recognizing geothermal energy as assets for the country

Back before his college days, Novi was on a bus from Jakarta to Bandung, gazing out at the mountainous landscape A thought suddenly hit him: “Why not harness the steam from these mountains to generate energy?” Little did he know, that question would spark a career that has now spanned over 30 years of his life It reminds me of Mitch Albom’s book The Five People You Meet in Heaven follows the life and death of Eddie, a ride mechanic who passed away in an amusement park accident In heaven, Eddie meets five people who had a significant impact on his life one of whom he doesn’t even remember

Our lives are intertwined in ways we might not fully realize, every moment holds significance, even if we’re not always aware of it Remember the old man who helped Novi discover fumarole in Rantau Dedap? He might be the common thread of Novi’s life Who knows?

Novi admits he is nowhere near the ambitious type His journey shows us that resilience and a willingness to do things differently can lead to remarkable achievements Embrace challenges with a curious mindset, step out of your comfort zone, and keep an open mind

SITE UPDATES

SEML SITE UPDATE

(Q2-2023 TO Q2-2024)

By: Zakaria Zamrudioko Sumantoro

Starting from SHE aspects, where SEML Site SHE performance has been excellent during this period, concluded with No Fatality and LTI records Statistical data shows that SEML has achieved a total of 11.898.334 safe man-hours until May 2024, which is calculated from the last LTI occurrence on 12 June 2018 Several recognitions from government and certifications were also obtained during this period (Q2 2023 – Q2 2024), such as: PROPER with Blue Rating, Subroto Award for Safety and Environmental Management with Aditama Rating, Zero Accident Award from Ministry of Manpower, Re-certification of ISO 14001 on Environmental Management System, and certification of ISO 50001 on Energy Management System This achievement cannot be achieved without the awareness of every employee, SHE team and collaborative effort from each department and management support to continue making necessary continuous improvement in the field However, achieving safe man-hours is just a number Awards are just a bonus SEML should not be complacent with these achievement SEML shall continue to grow and move from its comfort zone Several programs and innovations continue to be carried out to keep up and improve on what we have already achieved

From operational perspective, SEML finished the year 2023 with a strong and reliable performance, where total net generation delivered to PLN’s grid reached 713,352 MWh or 104 85% greater than the annual guaranteed Take-Or-Pay (TOP) target as required by the PPA The yearly plant equivalent availability factor amounted in a superb number of 99 12%, which reflected a proper O&M management during the year There was no planned outage within 2023, as the upcoming major outage is planned to be conducted at the end of 2024

Apart from the excellent performance of the plant in 2023, there was a significant increase in plant unscheduled outage hours in 2023 compared to 2022 (54 18 vs 4.08 hours). The highlighted contributor for this high figure was the solenoid valve of all Turbine Stop Valves actuators, where the problem in June 2023 consumed more than 28 hours for troubleshooting After that, the problem at the solenoid valve is still often identified during routine Automatic Valve Test (AVT) However, permanent solution to replace the solenoid valve is scheduled to be performed during next Major Outage in November 2024

SEML Generation Statistic 2023

In terms of well configuration, there were no changes during this year where the same scenario as previous year is still maintained From December 2023 to February 2024, Annual Logging campaign was conducted by Subsurface Team for all production and injection wells During this campaign, initially the major production well ML-F2 was planned to be introduced to the system to replace MLH3, H4 and H5 wells

However, the WHP after logging campaign was still high and stable around 37 barg, which was still considered unsafe to flow into the system due to limitation at surface piping facilities rating Due to this situation, it was decided to maintain ML-F2 in bleeding condition and vented to the local AFT, and has not been introduced into the system yet until upgrades at surface piping facilities is performed

From power plant operational process, the underlined challenge was in Mid 2023 when data from generation condition indicated that Plant Rated Capacity (PRC) condition was difficult to be achieved during day time It was suspected that Cooling Tower performance has been degraded and affect generation capability of the plant Then, several action items have been set up Maintenance team immediately replaced and cleaned all the spray nozzles at Cooling Tower Shock chemical dose was also performed with the help of Ecolab At the end of August 2023 cooling tower performance has been recovered and plant wa able to reach PRC value The cooling tower approach has returned to less than 50C as per design after those action items were performed

Another routine yearly activity is to perform Plant Rated Capacity (PRC) Test, which was conducted on 15 November 2023 from 06:00 AM to 14:00 PM The newly declared capacity based on this PRC Test is 86 56 MW net (previously was 86 26 MW net) The new value is used immediately starting from 16 November 2023 at 00:00 AM and yearly generation plan with PLN (AFPM) was also revised to reflect the new PRC value

Next significant update was at the end of 2023, SEML Laboratory has been ready for operational purposes With various sophisticated instruments such as ICP (Inductively Coupled Plasma), IC (Ion Chromatography), Autotitrator, GC (Gas Chromatography), UV-VIS and BOD, currently the laboratory already provides routine accurate chemical analysis for both SEML and SERD

Sulphur deposit found at CT spray nozzle and distribution pipe

Before the turn of last year, several landslides and flashfloods have affected Muara Laboh facilities, and currently Engineering Team is working to restore the condition Flashflood at Bangko Hitam river is currently being reinstated by constructing slope remediation and repair the pipe support, while landslides mitigation at several locations are currently under study and countermeasure design with help of consultant Wetland construction project is currently also on progress with a completion target of early 2025

Sulfur deposit with thickness around 1,5 cm is found at distribution pipe

Different from 2023, Muara Laboh Geothermal Power Plant started the year 2024 with a more challenging situation, where in general PLN requested SEML to dispatch less generation more frequently during first semester of this year Up to end of May 2024, total export energy is 296,043 MWh or still 99 08% compared to the generation plan and contribute to 43 26% of year 2024 target Power plant technical availability factor to date is 99 67%, as a result of a plant forced outage at 14 January 2024 for 14 38 hours due to DCS Digital Input (DI) module problem During 1st semester of 2024, SEML also experienced two grid forced outages due to PLN’s equipment and transmission problem with total of 16 63 hours

Even though this start is relatively slow due to the number of forced outage and derating, as well as PLN’s limitation to dispatch more, it is hoped that the 2nd semester can lead to better performance and achievements at the end of year 2024, therefore inter-department collaboration needs to be established and maintained to achieve Muara Laboh Geothermal Power Plant succees It is also hoped that the upcoming Major Outage 2024 can also be performed smoothly and effectively, and completed according to the target so overall plant performance can be improved

In terms of Land Certifications, Field Relations team successfully obtained 17 of 20 certificates for Stage-2 Land Acquisition and hopefully by early July 2024, all of the land certificates shall be obtained

For CSR Programs, the team continues to deliver the scholarship program for undergraduate students namely Tunas Cerdas and prepare to deliver full scholarship for Solok Selatan outstanding students who passed the State University Test through Tunas Madya scholarship program Relations Team is also proud to share that 16 of 25 high school students or 64% of Tunas Pratama beneficiaries have passed the University Test through SNBP (National Selection Based on Achievement) and SNBT (National Selection Based on Test) SEML to fulfill the obligations to Geothermal Licenses, which to support education, started collaborations with educational institutions, by signing Memorandum of Understanding with Padang State Polytechnic (PNP) and Padang State University (UNP) This agreement, also following the recent agreement with Bung Hatta University (UBH), of which SEML also shares knowledge by supporting as Guest Lecturers in Bung Hatta University (UBH) and Padang State Polytechnic (PNP) Now the team is preparing for an agreement with Andalas University (Unand)

Not to mention, Relations Team also continues to deliver other CSR Program such as Safari Ramadhan altogether with Ramadhan Mubarak, blood donor and donation for natural disaster relief such as land slide and flesh flood at West Sumatra recently SEML Top Management also sent support to Moslem Group and Business Partner Sacrificial Cow for Haj Festivities by delivering 18 cows to surrounding community Besides that, the Security Team also improves security patrol by using innovation technology namely Security Drone Patrol to secure unmanned surface facilities

Biodiversity Team was also successful in securing the renewal of the Cooperation Agreement with Kerinci Seblat National Park

This cooperation strengthened our support to continue maintaining 52 5 hectares of Ecosystem Restoration Area near Muara Labuh Geothermal Power Plant The team also collaborated with SHE department to conduct Biodiversity Campaign in relation to World Water Day by planting 300 trees at boarding schools near the power plant

From Stage-2 Project update, the progress is still continuing with the preparation for construction of the Contractor’s accommodation facility and finalizing several contract and technical documents It is with high hope that Stage-2 Project can run well and smoothly, and can be completed according to the target with excellent quality

RAJABASA UPDATE: 2023-2024

A Promising Start in 2024

By: Meidina Dwisavira

In early January, SERB successfully secured approval for a 48-month extension of the Exploration Duration Replacement, retroactively effective from April 14, 2023, through April 13, 2027 This extension grants SERB the necessary flexibility to finalize the pending Power Purchase Agreement (PPA) with PT PLN and to complete the planned exploration program

Following this approval, SERB is now working on extending the Borrow-Use Permit (PPKH) for the Protected Forest area designated for exploration To support its exploration strategy, SERB plans to conduct hydrogeological and gravity surveys by the end of 2024

SERB remains committed to finalizing the PPA to commence exploration as soon as possible The PPA Amendment negotiations are nearing completion, with only a few remaining points to be resolved Additionally, SERB with PT Indonesia Power (PT IP), has conducted several meetings and asset assessment visits to advance PT IP's participation in the Gunung Rajabasa Geothermal Power Plant Project

Let us continue to pray and strive for the best so that the long-delayed Rajabasa Project can finally move forward, contributing to Indonesia's energy transformation and the achievement of Net Zero Emissions (NZE) by 2060

A VIEW TO BEHOLD AND A TECHNOLOGY MASTERED, CHRONICLES OF THE 2024 SHORT TERM TRAINING SCHOLARSHIP ON GEOTHERMAL PROJECT MANAGEMENT - NEW ZEALAND

By: Bima Aryaputra

Ahoy! The skies were grey, heavy wind permeates the skin, clouds teasing light rain but all that was beauty welcoming our batch of trainees for a wonderful experience

The Geothermal Project Management (2024) is a Short-Term Training Scholarship that is a collaborative effort between The Government of New Zealand and Indonesia. This has become a yearly event accommodating “Students of Geothermal” from multiple sectors to learn deeply the intricacies of Geothermal Development It has become a breeding ground for great geothermal relations, as you get to connect with leaders, academics, policy makers in geothermal energy and share your experiences with other geothermal proponents This program lasts roughly one whole month in which day-to-day activities include lectures, exercises, discussions, and even a site visit to some of New Zealand’s top Geothermal Power Plants

Candidacy process was done internally, and selection of participants were chosen by ESDM After going through a couple of simple administrative processes, we were warmly greeted by our Training Program providers, Skills

They made sure that all information and accommodation needs were fulfilled prior to our departure Skills also made sure that every participant would make it to the promised land and made sure that our stay was one to remember and meaningful

We took off and quickly descended to our destination, Auckland Making friends along the way, we were quickly acquainted with fellow Geothermal industry participants We had a range of expertise from Geologists, Engineers, Environment, Finance, Legal from both Indonesia and the Philippines. Everyone being very kind and extremely savvy in their respective fields created an engaging atmosphere Upon our arrival, we were given a brief introduction to our course and stay, before a much-needed day off to alleviate our jet-lag

Upon arriving at our respective homes for the next month, the meat of the crux, that is our classes awaits us After our first class, we were treated to a little taste of Kiwi culture. The opening ceremony conducted at The University of Auckland’s Old Government House was delight Quickly enveloping ourselves in all things geothermal, we were guided by some fine lecturers with tons of experiences within Geothermal Operations

Topics range from basic introduction to geothermal all the way to detailed courses on geothermal financial engineering and reservoir engineering. The topics covered can at times be overwhelming due to our departmental limitations, however groupings have been assigned to each one of us to make sure that everyone can keep up with experts in various fields filling out every table.

The weather having quickly changed from wet and rainy to windy and cold, we close out our first few weeks We were getting acquainted with the city of Auckland and enjoyed a couple of dayoffs with our new comrades, but everyone was eager to approach the next couple of days traveling to Taupo Alas, we were all but ready to head out of Auckland to go visit some of New Zealand’s Geothermal Power Plants. Along the way we stopped by a couple of beautiful sceneries signature to New Zealand.

Staying at a uniquely older styled hotel, we spent our first night out of Auckland being greeted by Geothermal proponents from Contact Energy, WINGS, Mercury and Tuaropaki, of which a couple familiar faces to Supreme Energy were present The industry networking banquet enabled us to exchange stories and experiences thus gaining so much perspective on differences and difficulties each of us must go through in geothermal energy establishment. The field visits around Taupo’s Geothermal Power Plants also showed us how different our Geothermal systems can be. At a glance our power plants may seem somewhat similar but a quick lookaround will tell you incredible differences between our establishments

On our last night in Taupo, we took on a local Māori style banquet Greeted with a traditional war dance, we made sure we chose a formidable tribal chief from our group (definitely not us) Exchanging pleasantries and cultural stories, we got a glimpse of New Zealand’s history in a nutshell

A hot cooked meal using traditional Hangi methods, we were more than ready to indulge A thanksgiving-like dining experience filled with Hakas and traditional songs closes out a much beloved part of the training program

Returning to Auckland, we turned our attention to the final business case presentations due on our final days of lecture Luckily our group started early, thus we stayed far away from weekend crunching After completing all the courses, encompassing the entirety of Geothermal operation (from conceptual models, thermodynamics, project elements, sustainability, SHE, drilling program, financial modelling, risk analysis, community & social considerations, etc.), we presented our final business case project assigned to us on our first week. After having a panel of judges appraise our case presentations, we readied ourselves for Graduation and farewell to our lecturer and training providers

Overall, the course provides great knowledge and insight for any of us who have been working in the Geothermal industry for years You get big chunks of information and knowledge of what each of us do to ultimately establish a Geothermal Power Plant and run it well Having the course take place in New Zealand is the icing on an already delicious cake. There are so many wonderful activities you can do on your days off to get rid of your homesickness during your one month stay away from your friends and families. Hiking in New Zealand provides an array of wonderful sceneries, a boat ride to any nearby islands also brings so much joy If you’re quick on your feet with plenty of stamina to waste, go to the Southern Island for an even more complete experience The opportunity was one for the advancement of Geothermal Development in Indonesia, but no one said you shouldn’t have a great time doing it All in all great networking was made, insightful knowledge was received, and countless memories made

THE BENEFIT OF PLANNED MAINTENANCE AND THE CRITICAL ROLE OF MAINTENANCE PLANNER - DUBAI

By: Munggang Hendro P

Muara Laboh geothermal power plant has been performing well. Statistical data shows very good indicators that all operational targets can be achieved A quote from Jonathan Ive, the senior VP of Apple Incorporated, said that good is the enemy of great Some fail to achieve greatness because they settle too quickly for comfortable life Most business organization can attain a level of adequate functionality, but instead of progressing beyond this point, they simply stagnate there Being okay, not bad, not great, is a mindset that might trap Muara Laboh to just become a mediocre establishment and prevent the organization to grow beyond its potential

The capability of Muara Laboh geothermal power plant to continuously operate at the declared capacity is the lifeblood of the company Anytime the plant is not available, there will be no electricity sales and no revenue The plant must be reliable 24-hours a day and 7-days a week to be able to capitalize the opportunity coming from the electricity demand at the grid. However, the plant is not reliable by itself The plant must be maintained

In a traditional maintenance approach, the maintenance requirements are defined from supplier advice and legal requirements These requirements are executed and then repeated perpetually; no innovation, no lesson learned, no improvement, because all the tasks are just simply following the manual and the code even if they are not relevant with the actual operating condition. In todays day and age, where competition is tough and the world demands striving for continuous improvement, such traditional approach is the quick way to destroy the establishment because we keep doing what we have always done and nothing to improve Following supplier advice blindly eliminates the cycle of learning opportunity to continuously refine and improve the process Over time, equipment will start to age and lose performance. Equipment problems will happen more frequently. Maintenance cost which is often the highest fixed cost burden in an organization will also increase What needs to be remembered is that the maintenance cost cannot grow unlimited. There is always a limit related to the maximum maintenance cost that can be tolerated to achieve the intended standard of equipment availability, capacity and reliability

Study reveals that, on average, 30% of maintenance works is not necessary Allowing the unnecessary works can waste time, money and effort Omitting the necessary work can affect reliability and cause problems that leads to loss of generation. Work optimization is key to find good balance to maintain high reliability at an optimized cost

Another surprising data shows that productivity of maintenance personnel is only 35% The remaining 65% of maintenance personnel time are spent on nonproductive activities such as necessary break time, undesirable job delays to get parts, instructions or tools. This is where the role of maintenance planning is critical. Maintenance planning will improve maintenance efficiency by reducing unproductive maintenance time.

The following short narrative stories can give us a sense how important maintenance planning is by comparing typical maintenance activity between no planning vs with planning

NO PLANNING

Benny was a mechanical technician, he arrived at 7.30 AM and reported ready for assignment. His supervisor gave him a job: take care of a leaking valve at pad B.

The supervisor did not think that the job would take all day and told him to come back for something else to do when it was finished

Benny went to the tool room to take the necessary tools. On the way, he met Arif. Both chatted and shared info of what they would do during the day After getting the tools needed, Benny called control room to inform his plan at pad B Control room operator checked the work permit Unfortunately, the work permit was not ready yet Benny needed to submit the work permit first It took almost 2 hours to complete the necessary permitting

It was 10 00 AM when the permit was issued Benny went to pad B and that took him 30 minutes to travel He arrived 10 30 AM and immediately checked the condition Benny opened his tool box and found that he missed one of the special tools needed Apparently, this special tool was used by another technician a few days back but he did not return it back properly He called his crew from the workshop to bring the wrench. The wrench arrived at 11.15 AM.

Benny continued his job He was able to dismantle the valve After inspection, the valve must be replaced Although the spare parts were available, some welding work was required. Benny called his supervisor, informing the condition. The welding team was already booked for another job and was only available after lunch break. It was already 12.00 PM, Benny decided to return back to the plant for lunch break He arrived at plant at 12 30 PM, he took his time for about 1 hour

At 1:30 PM, Benny and the welding team went to pad B again. He brought the new spare valve. They arrived at 2.00 PM. The welding team did their job; and the valve replacement was performed They completed the work at 3 30 PM Benny returned to the plant and arrived at 4 00 PM He reported to his supervisor that the job has been done; no more leaking was observed With only 30 minutes before his worktime ended, no more work could be assigned to him He spent his remaining time for some paperwork

Benny left plant at 4 30 PM On the way to his house, Benny felt he has worked very hard and how busy he was all day just to finish 1 work

WITH PLANNING

Budi was a mechanical technician, he arrived at 7 30 AM and reported ready for assignment His supervisor gave him a job: take care leaking valve at pad B The work plan included advise from condition monitoring team that the valve must be replaced. Some welding work was also necessary; thus the welding team was ready to support his job.

The plan gave the following steps :

o Obtain tools from tool room; list of required tools was complete so he did not miss any special tools; 15 minutes

o Obtain spare valve from warehouse; 15 minutes

o Work permit was already prepared in advance, he only checked with operator if the work area was clear; 5 minutes

o Travel to pad B; 30 minutes

o Replace the valve; 2 hours

o Travel back to plant; 30 minutes

o Total time: 3 hours 35 minutes

Budi reported back to his supervisor just before lunch He was still able to complete several paper works . After lunch, he was also able to finish 2 other works before he ended the day

The two stories above easily show the benefits of planning. Proper planning can increase productivity Unplanned works tends to create a lot of unwanted conditions A typical indicator of when unplanned works still becomes a major part of daily tasks are urgent reactive works relation to equipment breakdown In any breakdown case, the total cost incurred is not only the cost to repair, which is usually more expensive because everything is urgent, but also the cost associated with the loss of production Team morale is also low because they will always act in firefighting mode

When planned maintenance is in place, the majority of tasks are shifted to proactive maintenance that focus on future activities Proactive maintenance means to act before breakdown occurs by recognizing and addressing the situations to prevent them from becoming urgent problems.

Planned maintenance provides many benefits, such as :

1) Greater plant reliability and availability

2) More predictable maintenance

3) Less urgent work and breakdowns 4) Lower level of stress 5) Calmer and safer working environment

In order to establish planned maintenance, the role of planner is needed. The Planner is a member of the maintenance team who is not on craft-crew and shall not performing any physical task at field Planner shall focus on future works while craft-crew shall handle the current day’s works and problems. Planner is not involved in work that is already on going When the crew has started working on a job and they find problem, they do not come to the planner for assistance but work it out by themselves After the crew successfully completes the current job, they will provide feedback to the planner to help avoid similar problem in the future

A study has shown that a proper planning can improve the productivity of 1 technician or 1 craft-crew by a factor of 1 57 In a crew of 13 members, if 1 is assigned as planner, the productivity of the crew does not become 12 but become 18. It is similar to adding 6 additional crews by only reorganizing the existing manpower

Muara Laboh geothermal power plant still has a long way to go The operational life of the plant is expected to be at least 30 years as per Power Purchase Agreement (PPA) and beyond Good performance in the past still relied on several individuals act as “heroes”

“Heroes” is a term that refers to individuals who excell after fixing the equipment when there occurs. “Heroes” are undesirable, because this will create a behavior pattern where people are rewarded after fixing the problem instead of maintaining the equipment to prevent problems from occuring

For sustainable success, Muara Laboh shall improve by relying on business process where planned maintenance is implemented By shifting to business process, Muara Laboh will continue to grow without depending on individuals because the power to grow is fueled by a high performance team that is not only perfect inside their respective area but also able to expand and collaborate with other teams

Training Venue

The improvement efforts have been implemented by establishing a dedicated planning section within maintenance organization and reshaping the asset management implementation since Q4 2023 Several programs have also been prepared and will be executed gradually until the end of 2025. These include refining the asset register list, updating functional failure assessment for critical equipment, establishing Bill of Materials (BOM), setting up inventory module and integration with planning, revising Work Order management flow, updating all procedures and work instructions, standardizing personnel competency matrix, setting up Life Data Analysis (LDA) and setting up Failure Root Cause Analysis (FRCA)

The indicators that Muara Laboh organization has achieved the intended maturity level will be reflected by the following conditions: the business is consistently thriving beyond healthy profit margins, all employees have very good morals and contribute to the success of the company, becoming a partner of choice to all stakeholders and local community A structured, systematic approach and cross departments teamwork in accordance to the SUPREME values as our corporate identity is required to achieve success. Let’s accelerate, grow and succeed together!

Dubai Marina at Night

This article is based on two main references: Maintenance Planning and Scheduling Handbook 2nd Edition written by Richard D Palmer and Training Materials from Certified Maintenance Planner (CMP) course conducted by Meirc Training & Consulting and delivered by Laurie Dummett The author was assigned to attend the CMP course in Dubai on 10-14 December 2023 to lead planned maintenance transformation and implementation at Muara Laboh The training was an eye opener, emphasizing the critical of planning function in an organization and the importance of process culture that relies on everyone instead of informal culture that relies on individuals It is an interesting fact that the training occasion was in Dubai, an amazingly well-planned city in Middle East Dubai was just a fishing village in the early 18th century Dubai joined with other emirates and formed United Arab Emirates in 1971 The period of 1970’s was the start of development of modern Dubai where strong vision and leadership from the ruler was combined with proper plan Dubai then transformed into a modern city and an important commercial hub in the region Dubai is a true evident that, no matter how low you start, continues improvement and small consistent step is more crucial than easily satisfy with what we currently have and stop to grow

As he settled into his role, Taguchi felt at home with Supreme Energy The company’s culture encouraged open communication and quick decisions This was different from the more formal structure in Japan Taguchi was hopeful about the future, especially the potential of the Rantau Dedap site Despite challenges, he believed in the site's growth and was determined to see it expand

Taguchi’s journey from Tokyo to Jakarta was marked by ambition and adaptability His story showed the importance of perseverance and seizing new opportunities Looking ahead, Taguchi lived by his motto:

“Try everything, even if you fail. Every step is progress. Never give up.”

RENEWABLE ENERGY COLUMN

By : Faisal Andre & Zakaria Zamrudioko Sumantoro

Energy is one of basic human needs However, inefficient use of energy not only drains limited natural resources, but can also cause environmental damage and harm the company's economy Therefore, efficient energy planning and management is very important

WHAT?

Based on Government Regulation (Peraturan Pemerintah – PP) No33/2023 regarding Energy Conservation, energy users of at least 6,000 tons of oil equivalent (TOE) are required to carry out energy management, appoint energy managers, prepare energy conservation programs, carry out periodic energy audits, implement recommendations from energy audit results, and report the implementation of energy management annually to the Government

Therefore, the implementation of ISO 50001:2018 Energy Management System (EnMS) is very important to compliance with government regulation The international standard ISO 50001:2018 Energy Management System (EnMS) establishes an organization's energy management system, which aims to ensure that each organization is able to build the systems and processes needed to improve its energy performance The energy performance in question includes energy efficiency, use and consumption

Implementation of EnMS

Starting in August 2022, SEML Site Management appointed an Energy Manager and established an Energy Team, with responsibility including planning, implementing, monitoring and evaluating the energy management Certification process for Energy Manager and Energy Auditor were also carried out to support this program

In early 2023, a Management Representative (MR) has also been appointed for the EnMS whose job is to ensure that the EnMS has been established, implemented, maintained, continuously improving and complies with the requirements of the ISO 50001:2018 standard During this period, SEML has also engaged with PT Sucofindo to conduct their first external energy audit, including delivering awareness training for all SEML employees regarding EnMS

At the end of 2023, SEML Energy Team has established and implemented several programs for energy management system, such as stop 1-2 Cooling Tower Fan during low generation, switchoff outdoor lighting manually at Wellpads if there are no activities, and install motion sensors at several rooms in Admin Building The team has also prepared several documents required for ISO 50001:2018 certification compliance, including performing Management Review (MR) to ensure that all processes has been communicated and reviewed by management HOW?

The commitment of PT SEML's top management in implementing EnMS has been stated in the SEML Energy Policy (ML-SMGGEM-POL-0007) which was announced in August 2023

Certification of EnMS

PT SEML has also carried out its energy management reporting obligations in the energy supply sector for the 2023 period to EBTKE on 13 March 2024 through the POME (Pelaporan Online Manajemen Energi) application, and has been approved by EBTKE on 14 March 2024 This reporting is in accordance with PP No33 Tahun 2023 regarding Energy Conservation In 2023, SEML successfully contributed to energy savings of ± 1,116 GJ and succeeded in reducing energy consumption by 0 35% compared to the baseline

On 1 April 2024, the BSI Group certification body, conducted an assessment of PT SEML's Energy Management System The assessment was conducted to confirm that the PT SEML has effectively implemented the planned Energy Management System, and to confirm that the management system is capable of achieving PT SEML energy objectives

Based on the result of the audit certification, PT SEML is recommended for ISO 50001:2018 certification with the scope of certification “Geothermal Power Plant Main Facility and Admin Building” The ceremony of the certificate handover was performed on 11 June 2024 at SEML site by BSI representative In the future, hopefully SEML can continue to be consistent in implementing energy management and energy conservation programs

SEML’s Sustainability Drive to combat climate change and its impacts through ISO 14001:2015 Environmental Management System Implementation

By: Fikry Rhidany & Faisal Andre

Climate Change is a Human-caused increases in greenhouse gases process that has been the major influencing factor on global climate change over the past 140 years The climate change we are currently experiencing, however, is caused by human activities such asfor burning of fossil fuels (coal, natural gas and oil), deforestation (cutting down trees) and natural processes such as volcano eruption

In response those issues, SEML continues the implementation of an Environmental Management System (EMS) ISO 14001:2015 to addres environmental challenges by minimizing environmental impact, enhancing green and renewable energy by tapping the earth’s geothermal potential and mitigating associated risks significantly improving the environmental performance of the company.

Sustainability is currently at the forefront of Supreme Energy Muara Laboh’s strategies, by striving to minimize SEML’s environmental impact One effective approach to achieving this goal is the implementation of the ISO 14001:2015 Environmental Management System (EMS) to conserve the environment for the benefit of future generations

WHAT ?

The ISO 14001:2015 standard allows companies to set-up an Environmental Management System (EMS) that will be help guide the company to reduce waste, improve resources efficiency and cut the cost of waste management and reduce environmental impact from power plant activities

Based on Government of Indonesia’s Regulation (PerMENLH No 1/2021) regarding Corporate Performance Rating Assessment Program in Environmental Management (PROPER), it is recomended that a company implements an Environmental Management System (ISO 14001:2015) implemented, with this implementation that will help them reduce waste, improve resource efficiency and cut the cost of waste management

HOW?

Implementation of EMS

SEML received its 1st Environmental Management System (EMS) certification from PT Tafa Sertifikasi Indonesia (TSI) effective on 04 May 2021 Starting on 15 April 2022, SEML General Manager issued a memorandum for the appointment of an Environmental Management Team, responsible for planning, implementing, monitoring and evaluating the Environmental Management System implementation at Supreme Energy Muara Laboh

The commitment of PT SEML's top management in implementing EMS has been stated in the SEML Environmental Policy (ML-SMG-GEM-POL-0002) which was announced in July 2023

In At the end of 2023, SEML Environmental Management System has was established and implemented several programs for EMS, such as updatinge SEA (Significant Environmental) Aspect and Impact evaluation, assigned an energy Manager as part of previous nonconformities, minimized hazardous waste generation & and updated the EMS to SEMIMS (Supreme Energy Muara Laboh Integrated Management System Manual

•

Re - Certification of EMS

Due to the expiration of the 1 st Environmental Management System (EMS) certification on 4 May 2024 , PT SEML continued the with its EMS recertification by conducting an audit by BSI Group as a certification body on 1 April 2024 This audit was also carried out together along with other certification audits, that isnamely ISO 50001 : 2018 Energy Management System ( EnMS )

Based on the result of the recertification audit, PT SEML is recommended for ISO 14001 : 2015 certification with the scope of certification “The provision of operational and maintenance of Geothermal Power Plant” Continuing ISO 14001 : 2015 certification reflects PT SEML's deep commitment to minimizing PT SEML's environmental footprint and promoting sustainable practices throughout PT SEML's operations

FUKUSHIMA 50

Movie

Review by : Rahmatul Anggi

Fukushima 50 is an adaptation of the non - fiction novel On the Brink : The Inside Story of Fukushima Daiichi written by Ryusho Kadota The title "Fukushima 50 " refers to the small group of around 50 plant workers who stayed behind at the Fukushima Daiichi Nuclear Power Plant after the 2011 earth quake and tsunami disaster This movie depicts almost real case of how power plant workers handle emergency situation and give description of how thermal power plant work notably nuclear power plant . The film explores several scenarios that have a high likelihood of happening in other energy production facilities, particularly power plants that rely on thermal energy generation This movie is a mustwatch for anyone who wants to understand the high stakes involved in working at a power plant Power plant operators, technicians, and engineers will especially benefit from the film's portrayal of critical incidents and the lessons learned By watching this movie, these professionals can gain valuable insights to prevent similar accidents from happening in their own plants

Now, let me delve into the movie's storyline for you The film opens by introducing Toshio Izaki , a dedicated Shift Operation Supervisor who cherishes his family We also meet Masao Yoshida, the Plant Manager, who shoulders the immense responsibility for all plant's operational It depicts the daily routines of the plant workers The world turns upside down when a massive 9 0 magnitude earthquake jolts the region Panic sets in as tremors shake the plant, triggering protection trip alarms which cause blackout occurred The real horror unfolds as a monstrous tsunami barrels towards the coast . The tsunami breaches the seawall, flooding vital equipment’s like EDG and disabling the reactor cooling systems . The plant plunges into darkness, communication lines are severed . Tensions rise as operators, technicians, and engineer’s scramble to assess the damage and restart the cooling systems before the reactors overheat With the cooling systems failing and radiation levels spiking, authorities order a plant evacuation Izaki and his colleagues witness the fear and desperation of fleeing residents

A moral dilemma emerges – should they prioritize their own safety or stay behind to prevent a catastrophic meltdown Witnessing the potential for a far greater disaster, Yoshida makes a life - changing decision He defies evacuation orders and rallies a group of around 50 volunteers, including Izaki , to stay and fight for the plant This group becomes known as the "Fukushima 50 " The remaining workers face a seemingly insurmountable task With limited resources, malfunctioning equipment, and soaring radiation levels, they work tirelessly to improvise cooling solutions using seawater and firetrucks Their efforts are hampered by constant aftershocks, conflicting instructions from superiors, and the growing fear of radiation exposure The film portrays the immense courage and ingenuity of the Fukushima 50 We see Izaki leading his team on daring ventures into highly radioactive areas to vent reactor pressure Yoshida confronts superiors and pleads for support, prioritizing the safety of his workers while pushing them to their limits The physical and emotional strain on the workers is immense Exhaustion, radiation sickness, and the constant fear of death take their toll The film doesn't shy away from showing the human cost of this endeavor Fukushima 50 doesn't end with the immediate crisis The movie portrays the workers' struggles to recover from the physical and psychological trauma It also sheds light on the ongoing impact on the surrounding communities, displaced residents, and the long - term consequences of the disaster The film doesn't present a black and white picture It touches on communication breakdowns between the plant and authorities, raising questions about crisis management Debates over nuclear energy and the decisions made during the disaster are presented without explicit judgment

This film powerfully portrays how power plant workers heroically manage an emergency situation, working tirelessly to secure the plant and prevent further escalation It emphasizes the critical role of every team member in ensuring plant safety, particularly highlighting the pressure faced by power plant managers and supervisors who must make crucial decisions under immense time constraints Nearly nine years after graduating from college, I've dedicated my career to working in thermal power plants, including coal - fired, gas - fired, and currently, geothermal facilities . This experience has given me a deep understanding of the challenges and experiences faced by power plant workers in the movie Having transitioned from operator to engineer, then shift production supervisor, and finally to my current role as plant evaluation supervisor, I've gained a firsthand perspective on the various roles within a thermal power plant Most of the equipment at the Fukushima Daiichi Nuclear Power Plant, except the nuclear reactor, is similar to what you'd find in other thermal power plants, especially coal - fired facilities Generally, I understand how the nuclear power plant works, thus I noticed a few scenes in the movie that seemed unrealistic compared to actual power plant operation condition However, despite these potential inaccuracies, the film remains worth watching and engaging I appreciate the movie director try efforts to depict how heroic is power plant workers to secure and tackle the emergency condition Watching this movie has deepened my understanding of the multiple safety layers incorporated into power plant design, particularly through methods like HAZOP, HAZID, and FMEA

This film delivers a powerful message It sheds light on the inherent risks and complexities of power plant operation, underscoring the critical need for comprehensive preparedness for unexpected emergencies . "Fukushima 50 " serves as a compelling testament to the extraordinary courage of ordinary people who rise to the challenge and become heroes . After all, not all heroes wear capes, everyone can be hero by their own way Here are some key takeaways I gleaned from the movie :

Leadership : Masao Yoshida, the plant manager, is portrayed as a leader who went into the danger zone with his crew This exemplifies leading by example and inspiring courage and commitment from his team in a crisis The movie shows how Yoshida trusted his team's expertise and empowered them to take action This fostered a sense of ownership and maximized the team's capabilities

Technical Expertise and Adaptability : The movie emphasizes the importance of deep technical understanding of plant systems and procedures The Fukushima workers' ability to operate the reactors under extreme conditions showcases this expertise The film also highlights the need to adapt to unforeseen situations and think critically to find solutions, a skill essential for all power plant workers

Importance of Safety Protocols : The tsunami that struck the Fukushima plant exceeded the design basis, meaning the plant wasn't built to withstand such a wave . Many plants have been reinforced to withstand stronger earthquakes and tsunamis . More robust plans are in place to handle severe accidents, including provisions for ensuring backup power and communication Regulatory bodies emphasize more comprehensive risk assessments that consider a wider range of potential hazards

The film portrays the immense pressure power plant workers can face during a crisis They are required to make quick decisions with limited information The rapidly unfolding situation at Fukushima demanded immediate actions to prevent a meltdown Delays in critical decisions, like depressurizing reactors or venting containment, could have worsened the situation

Communication and Teamwork : The movie hints at communication breakdowns between different teams at Fukushima This underscores the importance of clear communication across all levels of a power plant's hierarchy Effective teamwork is also crucial, as demonstrated by the Fukushima workers relying on each other's expertise to address the crisis

RESTORING NATURE’S BALANCE:

SUPREME ENERGY’S BIODIVERSITY AND ECOSYSTEM CONSERVATION

INITIATIVES

By: Ryski Darma B & Bakhtiar Aji

Supreme Energy is determined in their commitment to achieving a No Net Loss condition in its operations These commitments includes addressing impacts on biodiversity and ecosystem components through a Biodiversity Offset Program The concept of Net Loss refers to a situation where the losses in biodiversity and ecosystem services due to a company's operations are not only mitigated but are also offset to the extent that the overall impact is neutral or positive. In other words, Supreme Energy’s goal is to ensure that any negative impacts on the environment are balanced by actions that result in an equal or greater positive impact A cornerstone of this commitment is Supreme Energy’s comprehensive ecosystem restoration program During implementation, similar programs with different approaches for Muara Laboh and Rantau Dedap operation sites are apploed This tailored strategy ensures that our efforts are specifically designed to address the unique environmental challenges and opportunities at each location

In Muara Laboh, Supreme Energy Muara Laboh (SEML) has collaboration with the Kerinci Seblat National Park Authority (Balai Besar Taman Nasional Kerinci Seblat) This collaboration has embarked on a mission to restore vital ecosystems within the park’s rehabilitation zone. The collaborative efforts with the Kerinci Seblat National Park Authority began in 2020 through a formal agreement, which has now been extended for an additional three years, until 2026 This extended partnership underscores the long-term dedication to environmental management Through the offset program, Supreme Energy have planted approximately 27,000 trees, comprising of

10 native endemic species to West Sumatra and the KSNP landscape These efforts are aimed at re-establishing the native flora and providing crucial habitat for local wildlife, fostering a healthier and more resilient ecosystem

The data monitored has revealed the presence of several endemic and protected species, both nationally and globally, such as the Sumatran Serow, Sumatran rabbit, Sumatran tiger, and other unique species By enhancing habitat quality through the restoration of degraded areas, the aim is to maximize the forest’s function as a home for these important species The return of these species to restored habitats is a testament to the effectiveness of the efforts and the resilience of nature when given the chance to recover

Implementing an offset program comes with its own set of challenges, not only from natural factors such as invasive species but also from human activities Land clearing and poaching remain significant threats To combat these occurences, regular patrols is conducted to ensure there are no disturbances in the restoration area Supreme Energy’s dedicated team work tirelessly to remove invasive species and prevent illegal activities that could diminish the conservation efforts.

In the recent extension of the agreement, SEML and BBTNKS have introduced new initiatives focused on monitoring Sumatran tigers and clearing snares used to catch wild animals across a wider area. These initiatives are crucial steps in the ongoing efforts to protect and preserve the unique biodiversity of the region. The Sumatran tiger, a critically endangered species, serves as an indicator of the health of the entire ecosystem. By focusing on its protection, not only is Supreme Energy safeguarding a majestic species, but is also ensuring the well-being of the entire habitat.

The Rantau Dedap Operation site is undergoing a noteworthy transformation Under the stewardship of SERD, this initiative is not just about operations; but about restoration and the revival of the critical ecosystems within the Bukit Jambul Gunung Patah Landscape area, which serves as a vital habitat for several threatened, endemic, and protected species.

This unique landscape is home to the iconic Sumatran Tiger, the elusive Malayan Tapir, and the charismatic Siamang, as well as species of the highest conservation priority, including the Sumatran Surili and the Sumatran Striped Rabbit The importance of these habitats cannot be overstated, as they play a crucial role in maintaining biodiversity and ecological balance

In a collaborative effort with the Forestry Agency of South Sumatra, SERD has intricately aligned its restoration activities with broader watershed rehabilitation obligations The organization recognizes that successful restoration goes beyond merely planting trees; but revolves around a holistic approach including security patrol and natural disaster awarness to revitalize the ecological integrity of the region while addressing the socio-economic challenges faced by local communities

The journey has not been without its challenges One significant hurdle was acquiring land that had been previously misused within the Protection Forest area Restoring this degraded land, which was once a coffee plantation and consisted of shrubs and secondary forests, is a complex task

The presence of invasive plant species represents a considerable threat, as these species can inhibit the growth of native restoration trees, complicating the recovery of the ecosystem Despite these challenges, progress is being made To date, SERD has successfully planted a total of 87 hectares with more than 54,000 tree seedlings This initial stage marks a significant milestone in the restoration program, laying the groundwork for a healthier, more resilient landscape

Community engagement is another vital component of conservation strategy Supreme Energy works closely with local communities to raise awareness about the importance of biodiversity and the benefits of ecosystem restoration Educational programs and community involvement initiatives help foster a sense of stewardship among residents, ensuring the long-term success of our efforts

Together, Supreme Energy is making strides towards a more sustainable future, ensuring that operations contribute positively to the environment and the myriad of species that call it home Supreme Energy’s commitment to sustainability is not just a corporate responsibility but a moral imperative to protect the planet for future generations

As SERD continues their efforts at the Rantau Dedap Operation site, SERD remains committed to fostering biodiversity and ecological health in South Sumatra The ongoing restoration program not only aims to protect the native flora and fauna but also seeks to inspire and engage the community in actively participating in conservation efforts

EMPOWERING YOUTH AND PROSPERING LOCAL MOSQUES

By: Erwin Patrisa Floris, Livia Andita Putri

SEML firmly believes in conducting CSR programs that have positive impacts on society One of the CSR programs that has this impact is the Ramadan Mubarak Program which was initiated in 2022 This program is a transformation of the regular annual Safari Ramadaan program which was halted due to the Covid-19 outbreak One of the beneficiaries of this program is the AlJihad Youth Mosque, Pekonina This mosque is located at Jalan Raya Muaralabuh - Padang Aro KM 17, precisely in Kampung Tengah Pekonina Hamlet, Nagari Preparation Pekonina, Pauh Duo District, South Solok Regency Al-Jihad Pekonina Mosque is the oldest mosque in the Pekonina area This mosque is also one of the community engagement and communication spots for PT SEML during exploration activities in 2012 The Al-Jihad Pekonina Mosque has several activities apart from being a place for worship, including the male recital group, female recital group (Jamiatul Muslimah), Tahfidz activities and Services Mosque Youth Activities

Mosque Youth activities, consisting of children aged 15 years and over, are the driving generation for every activity carried out at the Al-Jihad Mosque, both in religious and social activities The Al-Jihad Pekonina Mosque Youth Community was formed on Thursday, April 23 2020 with a Management Composition chaired by Mr Wawan, treasurer Ms Rahma and secretary Ms Wati This management will rotate every year Mosque administrators provide financial loans to mosque teenagers to sell basic necessities during the month of Ramadan The results of these activities will be handed back to the mosque management During the month of Ramadhan 2022, PT Supreme Energy Muara Laboh for the first time, provided assistance aimed for the mosque teenagers with an amount of IDR 5,000,000

Because at that time there was a shortage of cooking oil, the Mosque Youth Community used this assistance as capital to sell basic necessities, in the form of daily necessities such as oil, sugar, flour, milk, etc. Apart from that, teenagers also receive merchandise from mothers, such as various kinds of Eid cakes The stalls stands right in front of the courtyard of the Al-Jihad Pekonina mosque using existing tables and tents Every day teenagers will take turns guarding the stall stands This stall is open from 09:00 – 17:30 WIB during Ramadan

At the end of the month of Ramadan, the capital is returned with a profit of Rp 11,000,000, - After Eid al-Fitr in 2022, the youth shop was forced to close because several administrators were continuing their education outside the city At the beginning of the month of Ramadan in 2023, mosque teenagers opened basic food stalls again Teenagers utilize pre-existing capital This stall lasts for approximately 30 days during the month of Ramadan At the end of Ramadan 2023, teenagers will get a stall profit of approximately IDR 804,500 So the total funds amount to Rp 11,804,500, -

In Ramadhan 2024, The Youth Mosque Community will open a stall again and on April 2 2024, SEML again provided financial assistance to The Mosque Youth Community an amount of IDR 7,500,000. This assistance was used by the teenagers to sell basic necessities and reopen stalls. Looking at the profits, it is very small because the aim of these youth stalls is not to make as much profit as possible, but rather to help people get basic necessities at affordable prices. Because during the month of Ramadan, basic food prices tend to be expensive and rare Teenagers sell basic necessities using a package system where each package contains 1 liter of cooking oil, 1 kg of flour, 1 kg of sugar, 5 eggs and 5 packs of instant noodles sold for IDR 50,000/package Apart from that, teenagers also sell using the retail system at prices that are cheaper than market prices

The existence of the Al-Jihad Pekonina Mosque Youth Community stall has had a positive impact, especially for the teenagers themselves Where it can create cooperation between teenagers in Kampung Tengah Pekonina Hamlet Apart from that, this stall also provides teenagers with experience regarding entrepreneurship, teenagers also learn how to develop a business without much capital

This youth stall only operates during the month of Ramadan, this is because the management still has student status So you only get free time during the month of Ramadan by taking advantage of the available holiday time To date, the assets owned by the Al-Jihad Pekonina Mosque's Youth stall amount to IDR 18,094,500

Hopefully this program will continue to have a positive impact on the Al-Jihad Pekonina Mosque Youth Community and can become an example or model for other Mosque Youth activities in South Solok

THE WORLD’S RAREST RABBIT

AS SEEN IN MUARA LABOH GEOTHERMAL AREA

By: Ryski D Busta

The Sumatran striped rabbit has a small body with an estimated length of 40 cm This rabbit is gray in color with black and brownish stripes, a red tail, a white belly, and short ears These rabbits are thought to be scattered throughout the Bukit Barisan Mountains based on the information found to date based on the IUCN classification, this rabbit only exist at Gunung Leuser National Park and Southern of Kerinci Seblat Natural Park (Orange polygon on the map)

The Sumatran striped rabbit is an endemic fauna to Sumatra which lack of information

Just thirteen museum specimens are known to exist, all of which were apparently collected within the first two decades of the 20th century Jeffrey Kastner in Cabinet Magazine wrote this rabbit is the rarest rabbit in the world

The IUCN Red List assessment in 2018 categorized this fauna as Data deficient, meaning there is insufficient data or information obtained regarding this rabbit Further research is needed to determine its distribution, population, habitat and threats.

SEML Biodiversity team installed eight camera traps to monitor and identify the biodiversity of wildlife using forest surround geothermal area as their home Camera traps were installed at several areas such as buffer area to KSNP and SEML’s offset area.

Camera traps installed around SEML’s area captured two photographs of Nesolagus Netscheri The recent record was on April 2024, meaning that forest area surrounding SEML is habitat to this rabbit This result is valuable addition to science, especially for distribution and population of Nesolagus Netscheri

Therefore, it’s become SEML’s responsibility to manage all Business Partners, and all employee to protect the forests that surround PT SEML area in order to preserve the habitat for “The World’s Rarest Rabbit” .

ATOMIC HABITS

Book Review By: Rahmatul Anggi

James Clear, a well-known author, wrote the best seller book titled The Atomic Habits Literally I wasn't interested in reading books before I knew about The Atomic Habits The story begun when I encountered a quote on social media attributed to James Clear from his book The quote said: "Improving by 1 % isn't particularly notable, sometimes it isn't even noticeable, but it can be far more meaningful, especially in the long run” and “If you can get 1 % better each day for one year, you'll end up 37 times better by the time you're done” Those quotes were so motivating and led me to find out more about these quotes in detail from the book its self

Initially, I had a hunch that this book would be a great read My intuition proved correct – I gained a wealth of valuable insights from it Unlike some self-development books message that advocate for drastic transformations, Atomic Habits champions the power of small, incremental improvements This approach makes the book feel less intimidating and more achievable for most readers In essence, the principles outlined in this book are readily applicable to anyone We often underestimate the power of small actions in our lives Unconsciously, these seemingly insignificant choices can snowball into significant changes over time Our daily habits, good or bad, shape who we are (our identity) To create a better future, we need to identify and replace even our unconscious bad habits with positive ones Focus on developing small, manageable habits that make taking action easier Phillippa Lally is a health psychology researcher at University College London In a study published in the European Journal of Social Psychology, Lally and her research team decided to figure out just how long it actually takes to form a habit. And the result is On average, it takes more than 2 months’ repetition before a new behavior becomes automatic 66 days to be exact consistently.

James Clear argues that goals are effective for setting direction, but systems are superior for achieving progress This concept is a key takeaway from his book While goals provide a roadmap, focusing solely on them can lead to stagnation once achieved Systems, on the other hand, encourage continuous improvement by making progress a daily habit

I gained many valuable lessons and insights from Atomic Habits, I'd like to share the four key principles that guide us in successfully forming new good habits

The first step is to make your new habit clear and obvious When forming a new habit, it's crucial to define it clearly and write it down as a reminder Similar to setting a goal, you can use the SMART method to create a specific, measurable, achievable, relevant, and time-bound plan for integrating the new behavior into your routine To make tracking easier, consider using a daily habit tracker or note-taking app

The second key is to make your new habit attractive Once you've established a clear routine, focus on making it appealing to maintain Here are a few strategies to achieve this:

1. Habit Stacking: Pair your new habit with an existing, enjoyable one For example, combine your morning coffee ritual with 15 minutes of reading a self-development book

2. Reward System: Implement a reward system to incentivize completion For example, reward yourself with a cup of tea after burning at least 500 calories

The third principle is to make the habit easy This approach focuses on reducing the initial effort required to perform the desired behavior The easier it is to initiate and complete, the more likely you are to stick with it However, there's a balance to strike A habit that's too difficult is less likely to be repeated, while one that's too easy might not be challenging enough to be sustainable. Aim for a sweet spot where you're still slightly challenged by the habit, but the effort required is minimal.

For example, when I wanted to cultivate reading as a hobby, I started with just one page per day Additionally, I kept a book readily available at all times, so I could access it easily whenever the urge to read arose

The fourth principle is to make the habit satisfying This step emphasizes associating positive reinforcement with the desired behavior to solidify the habit loop Here are a few ways to achieve this:

1. Track your progress: Marking your habit completion with a tick on a personal reminder can be very satisfying. This visual reinforcement provides a sense of accomplishment.

2. Build an accountability partnership: Find a friend or partner to remind or motivate you Social support can be a powerful tool for staying on track

The four actions outlined above provide a framework for transforming desired behaviors into lasting habits Conversely, these principles can be applied to break bad habits by making them difficult, unattractive, and unsatisfying

While I wouldn't claim to have flawlessly implemented every habit on my list, I'm proud to say that I've achieved consistent adherence to roughly 50% of them This accomplishment, achieved largely unconsciously through consistent small actions, feels significant from my perspective It demonstrates that what once seemed impossible can be attained through consistent effort

This book has had a profound impact on my life Reading it has significantly improved me as a person, and I wholeheartedly recommend it to anyone seeking positive change

Treasured thoughts of one so dear often bring a silent tear. Thoughts of scenes long past. Years roll on but memories last. Fondly remembered & always missed by all of us in Supreme Energy.

In loving memory of our dear friend who left us too soon, Teddy Wahyudi. Your laughter still echoes in our heart
