Indonesia has a target of reducing 29% of GHG emissions by 2030 (NDC, 2022), reaching net-zero emissions in 2060 (LTS-LCCR, 2021), and obtaining 1 million BOPD oil production and 12 BSCFD gas production in 2030. Oil and gas companies have particular challenges to achieve the target in line with paying attention to national energy security despite the oil reserve and production declining since 1995 because of the maturity of the fields. In such a case, the enormous amount of remaining oil in place left by the primary and secondary production stages has led to the EOR method as the best way to improve oil production. In Indonesia's mature fields with specific reservoir conditions, steamflooding is currently a highly effective EOR method to increase oil production by 20–300% and reduce viscosity by up to 98%. However, the production of steam in huge quantities conventionally would require vast amounts of fossil fuel resources. Hence, replacing fossil fuel-derived steam with solar-derived steam would solve the twin problems of energy scarcity and greenhouse gas emissions. Solar EOR is a viable alternative to gas-fired steam production for the oil industry by using the sun's energy to generate steam. For designing the long-term Solar EOR, Ayman Solar Concentrator (ASC) technology on low-cost solar thermal energy storage will generate high-temperature steam for 24 hours all day by enabling the system to achieve higher temperatures with less mirror surface. The evaluation of annual energy output from the solar project's design could save more than 8,672,400 MMBTU/year of natural gas and cut the environmental footprint up to 1200 metric tonnes per day of net CO2 so that natural gas can be sold and allocated to various sectors. Furthermore, the economic analysis shows that solar EOR has the lowest operational. This technology's novelty is its low cost and ability to generate steam to supply it upon demand in Indonesia's ongoing steamflood project.
印度尼西亚的目标是到2030年减少29%的温室气体排放(NDC, 2022年)，到2060年达到净零排放(LTS-LCCR, 2021年)，到2030年实现100万桶/天的石油产量和12 BSCFD的天然气产量。尽管自1995年以来，由于油田的成熟，石油储量和产量都在下降，但油气公司在关注国家能源安全的情况下，实现这一目标面临着特殊的挑战。在这种情况下，由于一次和二次开采阶段留下了大量的剩余油，因此EOR方法是提高石油产量的最佳方法。在印尼具有特定油藏条件的成熟油田，蒸汽驱是目前一种非常有效的EOR方法，可以提高20-300%的产油量，降低高达98%的粘度。然而，大量生产蒸汽通常需要大量的化石燃料资源。因此，用太阳能蒸汽代替化石燃料蒸汽将解决能源短缺和温室气体排放的双重问题。太阳能EOR是一种可行的替代燃气蒸汽生产的石油工业，利用太阳能产生蒸汽。为了设计长期的太阳能EOR, Ayman Solar Concentrator (ASC)低成本的太阳能热能储存技术，使系统能够以更少的镜面实现更高的温度，全天24小时产生高温蒸汽。对太阳能项目设计的年能源输出的评估可以节省超过8,672,400 MMBTU/年的天然气，并减少高达1200公吨/天的净二氧化碳的环境足迹，以便天然气可以出售并分配给各个部门。此外，经济分析表明，太阳能提高采收率具有最低的运行。这项技术的新颖之处在于它的低成本和产生蒸汽的能力，以满足印尼正在进行的蒸汽驱项目的需求。

The production process in the oil and gas industry, which is a major demand, still plays a huge role in carbon emissions, especially in the refining process. The energy and industrial sectors are responsible for more than 75% of these global CO2 emissions. This condition is an important issue regarding the effort to reduce climate change due to these emissions by implementing CCU. This article aims to examine methods of carbon capture with chemical absorption by solvents and to compose a model diagram of carbon utilization with microalgae. An extensive literature search was conducted in accordance with the scoping review methodology and the PEO framework. Our search criteria were limited to article research within the last 5 years (2017–2021). Themes found from this review included the CCU method in general, carbon capture by solvent method, type of solvent used, advantages and disadvantages, and utilization of carbon in the gas and oil industries. CCU is a model that can be offered as an alternative to reduce CO2 emissions produced by industry. The scoping review result shows the best method for carbon capture is with monoethanolamine (MEA) solvent. The flue gas from post-combustion streams into the absorption column and the solvent is added. The carbon-rich solvent is regenerated by heat to produce a clean solvent to be reused in the capture cycle. Carbon that has been absorbed by the MEA in the form of gas will be channeled through pipes to the microalgae industry as utilization of captured carbon and then converted to biofuels. It was discovered that MEA is a cost-effective solvent, efficiently captures carbon, and can be used repeatedly. However, the amine emissions from MEA are considered hazardous. The conclusion is that MEA solvent has advantages and disadvantages. Further optimization research is needed to determine the preeminent capture and separation process. Thus, it is necessary to determine the best conditions for the use of captured carbon by microalgae.

The demand for biofuels has begun to shift from first-generation biofuels to second-generation biofuels. One of the biofuels already planned in the government’s roadmap is renewable diesel from the hydrotreatment of palm oil. By 2040, the share of renewable diesel is projected to reach 1.4 million kL per year, contributing to 9% of the biofuel blend program. As the world’s largest palm oil producer and consumer, Indonesia has the opportunity to achieve a circular economy in the palm oil value chain by utilizing its waste and byproducts for biofuel production. However, there is a lack of a top-down perspective to assess second-generation renewable diesel potential from the palm oil sector in Indonesia. This study is intended to fill such gap by providing practical and comprehensive tools to develop the roadmap for second-generation renewable diesel in Indonesia, comprising of a conversion diagram and geospatial visualization method. Based on the results of this study, there are around 1,200 points of source (palm oil mills, refineries, and others) for palm oil-based waste in Indonesia with an approximate total of 1.4 million kL per year renewable diesel production capacity potential. Applicable waste-based feedstock from upstream and midstream palm oil sectors are palm oil mill effluent (POME) oil, spent bleaching earth oil (SBEO), and palm fatty acid distillates (PFAD). These are concentrated in the regions of Sumatra, Kalimantan, and Java to a lesser extent.

In Indonesia, for a half decade, the decrease of oil and gas production from 2016 is 4.23% and 3.53% respectively (ESDM, 2021). This production decrease has a domino effect on the investment loss. According to the International Trade Administration, investment in Indonesia’s oil and gas industry in 2019 reached around US$ 12 billion, which was decreasing from around US$ 16 billion in 2016. Such loss is a serious disaster, thus applying digital transformation such as machine learning to the most-used method, well stimulation, is immediately needed. Unfortunately, the implemented well stimulations nowadays are prone to short-lived effects due to the unreliable selection methods, as they do not have any integrated database. This research, as the pilot project, focuses on field data collected in West Indonesia from sandstone and carbonate lithologies, and the type of stimulation used is acidizing. This tool, OliFANT, defines the success of stimulation based on the productivity index before and after stimulation. The method uses geostatistical approaches and optimizing decline curve analysis for analysing and modelling spatially correlated data. The accuracy of the model is validated at a minimum of 75%, which shows its high reliability. It can also forecast the duration effect of the stimulation, additionally it provides the estimation of profit scenarios. The proposed machine learning model adopts an empirical working principle by utilizing reservoir parameters and test data of stimulation, which are inputted into a user-friendly interface after filling in a comprehensive database. In conclusion, the main benefits of using this tool are cutting evaluation time and achieving higher cost-efficiency. This software can be continuously improved by adding more data to widen the variety of the methods. Considering that each field has different types of properties, this tool is built to be adaptable to every reservoir condition. Over and above that, this tool can be implemented for other stimulated wells and be modified for other methods and operations, such as drilling and workover. In the future, it can be a one-stop solution for stimulation plan validation, where data-driven solutions pave the way for success.

Abstract. This study aims to analyze China's energy diplomacy regarding coal imports from Indonesia after restricting coal imports from Australia in 2019. After China limits coal imports from Australia in 2019, the supply of Chinese coal imports will decrease. This makes China need to increase its coal imports from other countries, one of which is Indonesia. Indonesia is one of the largest coal-exporting countries in the world. This can be used by China to meet its coal import needs. The author uses three indicators of Wang & Xu's energy diplomacy, namely dialogue between countries related to energy, government involvement in energy partnerships, and public energy diplomacy activities. The author uses qualitative research methods and internet-based research as data collection techniques. The findings in this study are: First, the dialogue between China and Indonesia, namely the meeting on 10 April 2019, the cooperation agreement on 24 May 2019 and 25 November 2020. Second, the Chinese government was involved in carrying out a cooperation agreement with Indonesia. Third, two Chinese non-state actors, namely CNCA and CCTDA.

Security studies debated the phenomenon of "high politics," such as politics and the military, at the outset of their development. As the study's object, it discusses the arms race, nuclear war, and political coups. Following the end of the Cold War, the economic, social, and environmental sectors became subjects of study in security studies. Not only that, but security studies also address issues that are frequently overlooked, such as energy issues. This is undeniably one of the most pressing issues in security studies today. The energy issue discusses how the country's foreign policy efforts will be carried out in order to avoid the threat of domestic energy scarcity. The inclusion of energy issues in security studies does not happen overnight. Through this scientific article, the author intends to examine how energy issues can become part of security issues. The author employs the concept of securitization to examine the securitization of energy issues from the standpoint of a security study. The author used a qualitative method in this study, with secondary data collection (journals and archive documents) as part of the data collection technique. The discussion of this scientific article has resulted in the securitization of energy issues being divided into three stages. Non-securitization, politicization, and securitization are the stages. Energy issues are not considered security issues during the non-securitization stage. When the energy issue becomes politicized, it poses a real threat that the government must address. Meanwhile, security issues have defined threats in the securitization stage. However, this securitization process will only take place if the audience accepts the threat and the state takes responsibility for mitigation efforts. The author comes to the conclusion that the securitization of energy issues is mutual between the state and the audience (society).

Carbon Capture, Utilization, and Storage (CCUS) have been a 'buzzword' for the past two years, especially in Indonesia, a developing country committed to achieving net-zero emissions. However, 43% of global CCUS projects were still terminated or put on hold, mainly driven by economic inability and public acceptance. Therefore, a suitable business model and clustering system must be proposed to make carbon sequestration projects economically attractive in Indonesia. Under the Analytical Hierarchy Process (AHP) assessment collaborating with the previous study conducted by Center of Excellence ITB and Lemigas, clustering systems can be deployed in three regions: South Sumatra, West Java, and East Kalimantan. The selected CO2 sources consist of various industrial sectors surrounding the fields, aiming to facilitate the source's matching process to the possible sink. Thus, it is obtained that the Talang Jimar field (South Sumatra) becomes the highest priority and the most probable sink point with 0.584 GtCO2 storage and an annual sink capacity of 0.0292 GtCO2 for 20 years storage period. Integrating CCUS deployment in Talang Jimar with a clustering system and advanced capturing technology seriously adds commercial value to the project. A carbonate fuel cell is the proposed capturing technology for coal power plants, with expected CO2 capture efficiency by 90% and reduced electricity cost by 33%. These developing technologies and clustering systems are forcing companies to find more efficient business models to compete in the carbon market. In this study, a joint venture scheme is applied to specify the CO2 value chain in this project and to cover the capturing and transportation cost through the joint-stock cooperative system, under sharing percentage assumptions of 40% for the capturing company, 30% for storage, and 30% for transport.

Geothermal resources are currently obtained from areas within volcanic arcs, such as the Pertamina Ulu Belu and Supreme Energy Rajabasa Geothermal Fields. However, this understanding may change in the future, as the Quaternary Sukadana Basalt Province (SBP), located in the back arc, is believed to have potential as a future geothermal energy resource. This research aims to explore the various factors that contribute to the high heat flow in the SBP region and generate a new perspective on geothermal energy particularly in the Lampung province. The methods used integrate previous research findings, such as heat flow data, regional tectonics, and geological structures, with new petrography-whole rock geochemistry. The whole rock geochemistry was determined using X-Ray Fluorescence (XRF), Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The SBP was formed by the Paleogene northwest-southeast striking fault and influenced by the Quaternary northeast-southwest striking fault, which may serve as conduits for hydrothermal fluid in addition to their vesicular structures. Geochemical analysis suggests the presence of both mantle plume and subduction-related processes. The magmatism linked to subduction-plume tectonic mechanisms and the thinning of the crust due to pull-apart motion caused by the movement of two large faults (Sumatra Fault Zone and Bangka Shear) can increase regional heat flow to 100±10 mW/m2. As a result, the SBP has significant potential as a source of geothermal energy for electricity generation in the future.
地热资源目前是从火山弧内的地区获得的，例如Pertamina Ulu Belu和Supreme Energy Rajabasa地热田。然而，这种认识在未来可能会改变，因为位于弧后的第四纪苏卡达纳玄武岩省(SBP)被认为有潜力成为未来的地热能资源。本研究旨在探索导致SBP地区高热流的各种因素，并对地热能特别是楠榜省的地热能产生新的看法。所采用的方法将以往的研究成果，如热流数据、区域构造和地质构造，与新的岩石学-全岩石地球化学相结合。采用x射线荧光(XRF)、电感耦合等离子体-光学发射光谱(ICP-OES)和电感耦合等离子体-质谱(ICP-MS)测定了整个岩石的地球化学特征。SBP由古近系西北-东南走向断裂形成，并受第四纪东北-西南走向断裂的影响，除了具有泡状构造外，还可能为热液流体提供了通道。地球化学分析表明，地幔柱和俯冲作用都存在。与俯冲-羽流构造机制相关的岩浆活动，以及苏门答腊断裂带和邦卡切变两条大断层运动引起的拉分运动导致的地壳变薄，使区域热流增加到100±10 mW/m2。因此，SBP在未来作为地热能发电的来源具有巨大的潜力。
{"title":"The Potential of Sukadana Basalt Province as a New Geothermal Resources in The Back Arc of Sumatra","authors":"L. Siringoringo, Candra Sadaperarih Sipayung","doi":"10.33116/ije.v6i1.150","DOIUrl":"https://doi.org/10.33116/ije.v6i1.150","url":null,"abstract":"Geothermal resources are currently obtained from areas within volcanic arcs, such as the Pertamina Ulu Belu and Supreme Energy Rajabasa Geothermal Fields. However, this understanding may change in the future, as the Quaternary Sukadana Basalt Province (SBP), located in the back arc, is believed to have potential as a future geothermal energy resource. This research aims to explore the various factors that contribute to the high heat flow in the SBP region and generate a new perspective on geothermal energy particularly in the Lampung province. The methods used integrate previous research findings, such as heat flow data, regional tectonics, and geological structures, with new petrography-whole rock geochemistry. The whole rock geochemistry was determined using X-Ray Fluorescence (XRF), Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The SBP was formed by the Paleogene northwest-southeast striking fault and influenced by the Quaternary northeast-southwest striking fault, which may serve as conduits for hydrothermal fluid in addition to their vesicular structures. Geochemical analysis suggests the presence of both mantle plume and subduction-related processes. The magmatism linked to subduction-plume tectonic mechanisms and the thinning of the crust due to pull-apart motion caused by the movement of two large faults (Sumatra Fault Zone and Bangka Shear) can increase regional heat flow to 100±10 mW/m2.

This paper analyzes South Korea's energy policy after the Fukushima disaster. The policy is seen from two dimensions, namely internal policies and external policies. The variable used in viewing the policy is through the framework described by Duffield. According to Duffield, internal policy responses can be seen from emergency preparations and reducing dependencies on foreign energy sources. In contrast, external policy response can be seen through policy toward energy-producing and transit countries, also other energy-consuming and importing countries. This research is qualitative with descriptive analytics. The study found that South Korea took several energy policies related to its domestic politics to reduce its dependence on energy imports. At the same time, for the external responses, South Korea intends to diversify its cooperation with the energy-exporting countries and continues to encourage international cooperation among the importing countries.

Almost all countries committed to tackling climate change as agreed in the Paris Agreement in 2015. In developed countries, the European Union (EU) issued the European Green Deal (EGD) with a target of 55% emissions reductions by 2030 and net zero emissions by 2050. Among developing countries, Indonesia has similar targets, which are 29% to 41% emission reductions by 2030 and net zero emissions by 2060 or sooner. EU countries and Indonesia also aim to implement energy transitions by increasing renewable energy shares, especially in the electricity sector, to reduce their emissions. Nevertheless, the EU countries have state-of-art research related to technologies and clean energy policies, allowing the EU as the first continent to commit to net-zero emissions by 2050. Our study aims to take lessons from recommendations in EGD and analyze their fitness for implementation in Indonesia. The research was conducted through a qualitative approach using secondary information and relevant references. We found that almost all recommendations for the energy transition in the EU electricity sector are relevant to Indonesia, except nuclear power plants and electricity tariff policies.
