Indonesia’s economy during the pandemic. One form of downstream mining as an economic strengthening capital is downstream coal mining, such as one in South Sumatera. Downstream coal mining through gasification technology is believed to enhance South Sumatra’s economic growth which all this time relies on the coal mining sector. It is commonly known that PT Bukit Asam (Persero) Tbk is currently working on the coal to DME (dimethyl ether) project in Tanjung Enim, South Sumatra. The coal gasification plant will produce which will be a substitute or replacement for LPG.

The COVID-19 pandemic this year also strikes the mining sector, especially the coal industry. Discussion on downstream mining cannot be separated from the existence of Job Creation Law which reaffirms the Mineral and Coal Law. The law is deemed to give a bigger certainty to the mining sector, one of which is that it allows royalty 0% for business player who enhances (downstream) coal added value. Chairman of the Indonesia Mining & Energy Forum (IMEF), Singgih Widagdo, stated that the existence of Job Creation Law was quite positive for the economic recovery, particularly in mining sector. Through the Job Creation Law, the state may solve many mining problems, particularly related to stagnant downstream mining. In his opinion, this is deemed to accelerate coal serving as the economic booster instead of merely a revenue driver. Singgih believes that this may also accelerate manpower absorption. Besides, the form of downstream mining expected to bring positive impact on the Indonesia’s economy is downstream nickel mining, of which one of its uses is to be raw material for lithium battery for electric car. Coordinating Minister for Maritime and Investment Affairs, Luhut Binsar Panjaitan, revealed that on the period 2014 - 2019, non-vehicle iron and steel export increased from USD 1.1 billion to USD 7.4 billion. In addition, nickel ore to

A Closer Look at Mining Working Condition during the Pandemic with Muhammad Firhan Qinthara Shift Supervisor at PT. Arutmin Indonesia Reporter M. Rifqi Rahmadillah | 12118007 Sarah Hasanah | 12118034

2020 is a year difficult to undergo for the worldwide society, particularly the Indonesians. The COVID-19 virus emerging in Indonesia since March 2020 has made any plans arranged in such a way to go in vain because of the rapid spread of the virus. This makes the society restless, thus the government forms the COVID‑19 Response Acceleration Task Force as the Indonesia’s frontline in fighting COVID-19 virus. The COVID-19 pandemic affects all of the existing sectors, including mining sector. In mining sector, most of mining works are performed on site and with direct contact one with another. This requires all companies to comply with government’s regulation related to the health protocol that must be implemented in mining activity areas. This starts with the adaptation of new normal by wearing mask, washing hands, and maintaining distance by mining companies in Indonesia, one of which is PT. Arutmin Indonesia. In Mineria 9.0 with the “Mining during Pandemic” theme, the Mineria team interviewed an employee of PT. Arutmin Indonesia from kintan mine, Muhammad Firhan Qinthara, an alumnus of Mining Engineering Department of ITB of 2015 whose position was Operation Engineering Supervisor Team. In the interview, we discussed and inquired him about mining during the pandemic.

What changes in and how the pandemic affect the mining working environment? From the start of the pandemic, PT. Arutmin Indonesia has not applied WFH (Work From Home) because of PLN’s increasing need for coal supply for electricity plant since many works are performed at home during the pandemic. For works on site, workers remain working by applying the health protocol. For example, a meeting which before the pandemic is performed directly (face to face) on site is performed at the office online during the pandemic. Mining ope­rators working on site still normally perform their duties since their works cannot be performed through WFH (work from home). Therefore, PT. Arutmin Indonesia does not apply WFH, but implements the health protocol well.

Does the pandemic influence commodity sales? Coal sale is divided into two, namely coal export and coal sale to domestic buyer or PLN. High quality coal (bituminous) will be exported, while coal sold to PLN is of sub-bituminous coal. There was significant impact on high quality coal since there was no export to Italia in the early COVID-19 pandemic. However, there was still contract with the government related to coal sale to PLN.

What is the mining company’s strategy for its survival in this uncertain period? There is no special strategy for the future. PT Arutmin Indonesia still operates as it used to and focuses coal supply. The most important thing is the existence of buyer (consumer) and PT. Arutmin Indonesia is ready to supply the coal as per demand annually.

Coronavirus also hits our country, Indonesia. With the first case registered in March 2020, the government has gradually applied the Large-Scale Social Restriction (PSBB) in order to hold the increasing number of COVID-19 positive patients down. This affects the Indonesians’ economy because of the restriction on many activities, including temporary closure of workplace and restriction on activities at public space. The economic impact is also felt by the global society. The worldwide society’s fear for possible global

economic downfall causes investors and speculators throughout the world to buy gold (commodity deemed to protect economic instability). The increasing demand for gold makes gold price to soar up to Rp1,056,000 per gram (Antam). This is taken advantage of by the society in Indonesian rural areas to mine gold illegally in areas deemed to have high gold content. The river flow around the Grasberg site under the coverage of PT Freeport Indonesia becomes one of the destinations of the illegal miners. The gold in the river

In one day, they may collect about 1 gram gold, that will be valued at Rp800,000, which is certainly tempting for the surrounding people. The dangers threatening the illegal miners are not only from possible exposure to the virus amidst the pandemic, but also from exposure to other diseases, particularly skin disease since they work on river flow containing mining waste of PT Freeport Indonesia. In addition, there is also a threat from the rebel (OPM) in their guerrilla operation in the forest and possible arrest by local security authority. Besides in the depth of Papuan forest, illegal mining is also performed by West Kalimantan people. Because of economic difficulty, the people turn to be gold miner on the rivers of their area.

The Indonesian government has made policy of coal gasification project in Indonesia. This policy is expressed in Presidential Regulation Number 109 of 2020 concerning the “Third Amendment to Presidential Regulation Number 3 of 2016 concerning the Acceleration of National Strategic Project Implementation”. Coal gasification project be­ comes one of about 201 national strategic projects launched by the Indonesian government. The project’s location is in Tanjung Enim, South Sumatera. Coal gasification is a coal reaction process using air or oxygen and vapor to produce gas product that may be directly used as fuel, or as feed for synthetic fuel (syngas) or any other gas or liquid chemicals. Below is the diagram explaining the route of coal changing into syngas products through coal gasification process.

From the perspective of Indonesia’s coal resource and reserve, we may state that Indonesia has very big poten­ tial for gasification project, since Indonesia’s coal resource and reserve value is quite high. Data show that the total resource and reserve in 2019 are respectively 149,009.59 million tons and 25,070.50 million tons. Indonesia’s coal resource and reserve are mostly dominated by low to medium rank coal. With the coal gasification project, the Indonesian Government expects an increase in coal’s added value, thus In­ donesia will no longer sell raw low rank coal abroad that certainly of lower economic value than DME. In addition, with gasification, Indonesia is expected to produce its own LPG and reduce its dependence on LPG import and maintain the national energy resilience.

PT Indominco Mandiri, PT Kaltim Prima Coal, PT Ken­ dilo Coal, PT Kideco Jaya Agung and PT Multi Harapan Utama. Pertamina and PT Bukit Asam (PTBA) Tanjung Enim & Air Products are currently cooperating on one of the coal gasification projects. The project is deemed relatively economic since PTBA will supply low calorie coal at affordable price. However, the physical work­ ing stage will just start from 2023 to 2024, since it first needs financial, technical and non-technical review, uti­ lization guidelines and regulation of coal gasification operation.

With regard to the age of each formation, Ja­ ten Formation is of upper Early Miocene epoch, while the Arjosari Formation is of oligo-miocene epoch.

Pacitan Regency and its surrounding areas are re­ gionally the transitional zone between subduction path of the Epoch of Limestone with Tertiary Period (Pur­ wanto, 1997). The structures developed in Pacitan and surrounding areas are fold, fault and joint (Sampurna, 1997). The faults in Pacitan and surrounding areas are generally normal fault and slip fault. Slip faults are ge­ nerally northwest-southwestward and northeast-south­ westward. The northeast-southwestward fault is hori­ zontally leftward, while the northwest-southwestward fault is horizontally rightward (Sudrajat, 1993). Thus, based on the structural pattern developed in Pacitan area, they are generally north-southward and south­ east-northwestward. Pacitan Regency area is gene­ rally composed of clastic sedimentary rocks, volcanic rocks, and intrusive rocks (Samodra et al., 1992). The IUP area where we performed the exploration activity was in the Jaten Formation and Arjosari Formation and passed by Pucunglangan Fault. The Jaten Formation

The purpose of exploration activity in the “Field Experience” was for bentonite mapping. Bentonite is classified into smectite-montmorillonite group, where montmorillonite is originated from plastic clay type found in 1847 in Montmorillonite, France. Bentonite is clay with high plastic and colloidal properties with main mineral content of smectite (montmorillonite) with content of 85-95%. Smectite’s theoretical formula is (OH)4SigAI4O20nH2O, with composition SiO2 66,79%, AI2O3 28,3 % and H2O 5 %. Commercially, there are two types of bentonite, namely calcium bentonite and sodi­ um bentonite. Calcium bentonite is used as absorbent material, cooking oil bleach, molding sand adhesive in steel casting process, as catalyst in chemical industry, feeder, etc. Sodium bentonite can be used as drilling mud in oil, gas and geothermal drilling, cement mix­ ture, leaking dam sealing material, etc.

tinue its operation. Beni was known as a man of vision who promo­ ted good mining practices. He was greatly concerned about environmental impact management, for ex-mining land to be greened or sustainable. Consciously, Beni applied the natural and cultural ecosystem sustainable principles, and even the survival of rare animals around mining areas. In addition, Beni was quite close to and concerned about surrounding society’s education. His commitment to good mining practices remains an important part of PT Vale Indonesia Tbk until now. In the interaction, he was known as an authoritative, decisive and principle bearing man. However, after getting acquainted further, he was a polite and kind-hearted man who was generous in giving guidance and advice, moreover, to the youth. In his activities, Beni was able to show that he was not only a geologist, but also an environmentalist, thus it is not strange that his name was perpetuated to be the name of a fish species living in Sulawesi. His departure will always be remembered and memorized in the Indonesian mining world.

How is the Online Job Vacancy? In line with technology advancement, the forms of job vacancy vary, from searching from career pages provided by companies or from LinkedIn, WhatsApp, Glints, and LINE group. Sometime, job vacancy is also delivered through e-mail that is sometime replied

MINING FRESGRADUATE’S JOURNEY WITH BANG YUDHA Muhammad Fikri Lazuardi - 12118067 Muhammad Raihan Aziz - 12118012

through telephone call. Bang Yudha always remind us to diligently and carefully send the letter. For example, receiving reply for next test, it is necessary to carefully identify whether it is a technical or HR test, since the two have quite a difference. Some matters also need to be prepared well, such as answer, mental, and clothing. Since it is usually sudden, Bang Yudha suggests to get ready. Bang Yudha also needs some months up to four months after graduation to search for a job, until he finally works with PT Vale Indonesia.

Figure Introduction Hello, Mineria friends! Who is unfamiliar with Bang Yudha? An alumnus of HMT-ITB in 2016 whose complete name is Pamursito Pradhana Yudhanto is a graduate of Mining Engineering, ITB July 2020. At a glimpse from his name, Bang Yudha is a man with in-depth thinking and analysis, good attitude, and high authority. Acquiring bachelor title, Bang Yudha now has the opportunity to work with PT Vale Indonesia as Junior Mining Engineer. During his study, Bang Yudha also has abundant organizational experience that is not less interesting, such as assuming the position of Senator HMT-ITB in the period 2019/2020.

all of them were tried. In addition, Bang Yudha also reminds us to proactively inquire senior alumni and mutually help friends, as simple as disseminating information we are aware of. Upon all efforts that we have conducted, the last tip of Bang Yudha is to be patient. Bang Yudha used to be optimistic to immediately acquire work after graduation. But after the process, Bang Yudha learned a lesson, “The definition of immediate cannot be determined by us, but that is what God decides for us, we just need to wait for fortune while keeping attempting”

35


Getting into a new environment? What skills are needed? We must be adaptable. Bang Yudha tells that in working world condition, the people will vary, from origin to character, background, etc. So, start to learn to adapt, from simple things, such as playing cards. According to Bang Yudha’s statement, people at PT Vale Indonesia are proficient card player.

In case of returning to campus life, what are to be grateful for and regretted, and any advice for us who are still at campus? Personally, Bang Yudha felt happy entering HMT. Many things were obtained by Bang Yudha at HMT, such as organization and competition experience. After entering working world, Bang Yudha feels that HMT is a depiction of mining work world. For example, the gathering culture at HMT which also exists in the working world. Continuing the story, Bang Yudha also felt lucky since at the Mining Engineering Study Program, ITB there was Mine Plan subject. Bang Yudha calls it capstone since all knowledge from TPB to department is applicable to mine plan. Thus, mine plan is a good preparation for the working world. As for something to be regretted, Bang Yudha regrets that he had never participated in a competition like paper or seminars. Bang Yudha also feels sorry since he did not save for participating in mining trainings, while if our profession resume is good, it will be our added value during user interview. Bang Yudha also suggests having as many interactions as possible with external world during campus life. For example, internship at Ministry of Energy and Mineral Resources or companies for additional knowledge and experience. Do not only rely on KP (Field Experience). In addition Bang Yudha also adds, for those who desire to continue their study, Bang Yudha tells that in PT Vale Indonesia there are also many seniors working while having magister program. Career while study may be taken into consideration since the course for the workers there is only held on Saturday-Sunday, online, and the credits taken are also relatively few. What then? Bang Yudha’s story is interesting, isn’t it? Let us prepare ourselves as best as possible to take part in the mining advancement for the Country development!

The Return of

MINEFEST HMT - ITB Lili Indriani Amir - 12117087

Minefest (Mining Festival) was a set of activities held by HMTITB as a medium of movement of creating an image of mining profession. Hayati Agustini as the Chairman of the Minefest 2021 revealed her reason of organizing this activity. She perceived that the mining world in Indonesia was currently dynamic. There were various challenges in a number of mining sectors which became many parties’ center of attention. Pros and cons emerged, making society elements continuously expressed their attitude and assessment. Therefore, the Minefest 2021 brought “let’s talk about mining” as the main theme aiming at describing that this event would discuss various matters concerning mining world. With the theme, it was expected that the Minefest would educate ordinary people on mining and facilitate national mining engineering students to improve their profession capabilities and knowledge of latest mining issues.

Minefest 2021 came with different set of operation from the last Minefest in 2015. Minefest 2021 was organized online because of the Covid-19 pandemic. Despite being organized online, Minefest 2021 attracted many people.

The agenda of Minefest 2021 included Mine Campaign, Opening, Poster Competition, Case Studies Competition, Webinar, and Closing.

Mine Campaign Mine Campaign was distribution of mining information and issues in the form of infographics, podcast, documentary video documenter, and virtual mine tour distributed through social media. For further mining knowledge, go to Instagram @minefest_hmtitb.

The form of mine campaign was quite exciting and varied, from infographics to podcast, video to virtual mine touring, which might help me study without even realizing it, it was fun and flowing while reading or listening to the information that it was conveyed eye catching, brief, and easy to understand. It was just refreshing, but still contained abundant knowledge including mining unique facts, mining issues, mining history, mining’s role in the national economy, and mining’s impact on the people. —Lisa Larissa Nugraheni

38


Poster Competition Besides, there was a Poster competition that evidently attracted many people, with 70 participants registered. The participants were not only from those with mining educational background, but also from various concentrations of study, such as medicine, economics, etc.

It was a great event! As a participant, I had felt the hype of the event. The committee’s hard work was really incredible that they performed that highly organized virtual event. I am looking forward to the best for the future minefest ITB event. Keep up the spirit in good deeds! —Rahmat Ramadhan Atrima, Winner of Poster Competition Minefest 2021

Rahmat Ramadhan Atrima Universitas Sumatera Utara Webinar In addition, there was a webinar with experts. The webinar themed the “Prospect and Challenges of Nickel Downstream Policy in Indonesia” did not only attract students, but also mining experts.

The current Webinar Minefest 2021 was quite impressive and exciting. It had interesting topic, professional speakers, and easily understandable delivery, appropriate to be a room for mining engineering students’ discussion. I gained more knowledge in this pandemic. I am looking forward to the next event! —Muhammad Piqri Ardiansyah

Case Studies Competiton There was also a Case Studies Competition. In this competition, participants were to complete mining case studies.

The Case Studies competition was quite impressive for us that it broadened and deepened our knowledge, especially in mining sector. Overall, the range of minefest activities was quite useful to all of us that it distributed mining science to the society. The committee was also quite professional, both in the course of the case studies and in other activities.. —Tim The Zheng, Winner of Case Studies Competition

39


Hayati states that as the leader, there were many things that she gained and learned from the Minefest activity. Organizing an event in such pandemic was not easy at all. Hayati said that she did not have high expectation, and at least what she plans was done. Although not 100% of Hayati’s expectations in early candidacy for leadership were achieved, she was still happy for many parties support. One of which was from lecturers of Mining Engineering, ITB that was quite helpful with inputs for the Minefest. There were ups and downs in organizing the Minefest from the start. Hayati stated that she was quite happy that HMT-ITB family entrusted the leadership to Hayati. In addition, there were many things to study. She had the chance to see different types of people while working. Behind her hard work as a leader, she said that her mind became uneasy, whether for thinking about the course of Minefest, financial aspect, process, criticism and inputs, or other matters. However, because of surrounding people’s support, she did it well. In addition, listening to people’s positive feedback, she felt that what she had done paid off.

Throughout the Minefest process, Hayati was aware that becom-

also stated that she did not require “Minefest” to continue, but at

ing a woman did not really prevent her from leading the commit-

least there would be an event with the same objective, expecting

tee, particularly in mining sector that was dominated by men. She

that people would be more aware of how the Indonesian mining potential was and not receive any unverified information.

Lastly, Hayati expressed her gratitude to her parents, core management of Minefest 2021, the whole committee, lecturers, brothers and sisters and alumni of HMT-ITB, sponsor, and partner media for their full support, inputs and criticism throughout the Minefest 2021.

Ben Felix - 12117031 These are the vocalists’ magic words before singing songs to entertain the bOSDangdut

What bOSDangdut Say?? `

It is quite sad that I can no longer watch OSD directly. When facing difficulty in the course, practice or exam, I used to watch OSD rehearsing until late (regular rehearsal) or performing at ITB! In my opinion, OSD’s performance is quite entertaining and can really relieve tiredness. Wait, it is not only entertaining, its songs and music are also enjoyable. I hope even in this pandemic, OSD will keep working hard and entertaining us! —Agnes Tia Novita, Student of Petroleum Engineering, ITB

44


OSD is so awesome, that it has accompanied us during the campus life with its unique and comical semi-dangdut rhythm, and even during the pandemic it keeps performing to entertain the campus residents. I hope OSD more glory, more favored by students, and of course its future works are awaited with messages that are no less cool than its previous songs. In the name of dangdut and love! —Ernesto, Student of Aeronautics, ITB
