Abstract

Street lighting can be considered the main energy consumer and greenhouse gas emitter at Indonesia's city level. In addition, public street lighting systems throughout Indonesia still use inefficient technologies, resulting in a significant portion of a municipality’s operating expenditure. We conduct techno-economy analysis and formulate financing mechanisms to support energy efficiency improvements on street lighting systems. In doing so, a pilot case based on a survey in one of the provincial capitals in Kalimantan is performed. From the survey, it is found that around half of the street lighting systems in the observed city are unmetered, dominated by CFL (Compact Fluorescent Lamp) lamps. Efficiency through street lighting system improvement can be achieved through, among others, replacement with a highly efficient light-emitting diode (LED) lamp, power meters installation and the replacement of high-efficiency armatures. Our analysis shows that energy consumption reduction potential from street light system improvements can reach 69% from existing conditions. In the showcase, it can save 9,466,465 kWh, equal to energy costs of IDR 13,676,202,724 and a 7,667-ton emission reduction. From the analysis, we also delivered a financial scheme for the project that incorporated local government and special mission vehicles under the coordination of the Ministry of Finance. Having great potential, a financing support mechanism can become a reference to another local government with a limited budget constraint. These findings can also provide policymakers with important inputs while improving street lighting systems as a key service provided by local and municipal governments.

Abstract

Through the Minister of ESDM K/20/MEM/2015 and Bali Governor Regulation No. 45/2019, Bali is designated as a clean energy area and has the advanced implementation of the energy transition towards renewable energy to attain SDG 7 "Affordable and Clean Energy." One of the main intensified directions is the development of solar rooftop energy. However, its development has encountered obstacles that hinder the operation's sustainability. Constraints include financing and community participation. This paper aims to provide solutions to catalyze public participation (especially in youth) for energy transition through the Crowd-Based Business Model, especially for Rooftop Solar Energy Power Plant or PLTS Atap. An integrated information system in the application that can increase investor interest in renewable energy, especially PLTS Atap, could be the answer. This Study uses data from literature studies and will be processed through qualitative content analysis, business model canvas, system design/flow analysis and SWOT analysis. This research will produce an application that is expected to be able to (1) understand the potential, benefits and considerations in using renewable energy, especially solar energy, by installing PLTS Atap in Indonesia (2) inform about financing schemes for installing and using PLTS Atap as a source of electricity generation on a corporate industrial and commercial scale (3) explain investment alternatives using crowdfunding and crowd sale with a certain level of profit that supports environmental values and renewable energy.

Abstract

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).

Abstract

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.

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. As a result, the SBP has significant potential as a source of geothermal energy for electricity generation in the future.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.
