Abstract

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.

Abstract

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

Geothermal energy is a source of renewable energy that has the potential to be produced, considering that Indonesia is in the ring of fire, where there are many volcanoes, one of which is Mount Anak Krakatau. Even though direct exploration is not permitted, at least information on the geothermal system on the mountain can still be obtained using satellite data. Therefore, this study aims to analyze the geothermal energy potential of Mount Anak Krakatau using gravity satellite data with a total of 320 data consisting of gravity disturbance, geoid, and Digital Elevation Model. The data processing describes a 3D model that is correlated with the First Horizontal Derivative (FHD) and Second Vertical Derivative (SVD) analysis. Based on the results of the residual anomaly map analysis, the low anomaly has a value of -1.85–(-0.89) mGal which is suspected to be associated with magma pockets, and the high anomaly ranges from 0.04–2.13 mGal which is suspected to be associated with the caldera of Mount Anak Krakatau. Based on the results of the FHD and SVD graphical analysis, there are 18 faults that control the geothermal system. Based on the results of 3D modeling trending from west-east it can be seen that there is a clay cap layer with a value density 2.32–2.37 gr/cc at depths of 0–550 m and reservoir layers with density values of 2.23–2.29 gr/cc at depths of 500–1100 m. This geothermal research using the gravity method can be developed and become a reference for future research to calculate the potential for electrification in a research area.

However, in Indonesia, the implementation of kinetic facades remains limited and requires further in-depth study. Thus, our research aims to fill this gap by exploring the opportunities and challenges of implementing kinetic facade typologies in Indonesia. The research method involves a literature review and descriptive analysis. We collect data on the use of kinetic facades globally, analyze the factors influencing their implementation, and identify the opportunities and challenges encountered. The analysis results are expected to provide a better understanding of the implementation of kinetic facades in Indonesia. The identified opportunities include the potential to improve energy efficiency, reduce carbon emissions, and enhance the interior and exterior environmental quality of buildings. The challenges identified may encompass technical aspects, regulations, financial issues, as well as market awareness and acceptance of this new technology. Our study contributes a foundation for further development of kinetic facades in Indonesia. With a better understanding of the opportunities and challenges, architecture practitioners, engineers, and policymakers can take appropriate steps to address the challenges and capitalize on the opportunities to integrate kinetic facades into building designs in Indonesia, promoting sustainable and innovative development in the architecture sector.

Abstract

Windows are a critical factor in enhancing energy efficiency in buildings, especially in tropical climates, where they are exposed to high-intensity sunlight. The incorporation of transparent photovoltaics using various PV technologies offers the opportunity for windows to harness solar energy for building purposes. The energy-saving benefits of using transparent photovoltaics have been extensively analyzed in various countries, but there is still a lack of comparative studies focusing on tropical countries. Our study aims to fill this gap by assessing the potential of transparent photovoltaics in enhancing energy efficiency in buildings located in Jakarta, Singapore, Kuala Lumpur, Rio de Janeiro, and Kotoka. We developed an energy consumption model located in a tropical climate, utilizing the EnergyPlus software. The simulation results clearly indicate that integrating photovoltaics into the building is particularly advantageous due to consistent solar radiation and the need for cooling and ventilation, resulting in a substantial up to 59.3% reduction in total energy consumption. As a contribution, our research underscores the potential of transparent photovoltaics to revolutionize building energy efficiency in tropical climates, providing significant energy savings and promoting sustainable building practices. Addressing climate challenges, such as temperature and humidity management, necessitates the utilization of advanced materials and design strategies. Additionally, policy challenges encompass the requirement for favorable policies, incentives, and well-defined guidelines for the installation of PV windows.

Abstract

The demand for energy is increasing along with the rise in population. Indonesian people rely on conventional resources such as coal, oil, and natural gas to meet their energy needs. It is estimated that coal can only be exploited for up to 61 years, natural gas for 34 years, and oil for 19 years. Meanwhile, Indonesia possesses unconventional oil and gas resources (e.g., coal bed methane (CBM), tight gas, shale gas and oil, and methane hydrate), estimated to reach 1,800 trillion cubic feet (TCF). These resources are in the exploration stage and have yet to be fully exploited due to technological limitations. Nevertheless, the Indonesian government continues to emphasize the development of this type of energy resource. Therefore, this study conducts a review of the potential of unconventional oil and gas resources in Indonesia, covering characteristics, potential occurrences in Indonesia, exploitation methods, utilization as a source of energy, and opportunities and challenges in their application. The method used is a narrative review based on secondary data by examining papers published in reputable national and international journals in the last ten years. Results show that unconventional oil and gas resources have different characteristics, including permeability, porosity, and depth. CBM can be found at the shallowest depth, followed by tight gas, methane hydrate, and the deepest is shale gas. Potential occurrences of these resources in Indonesia include gas hydrate (858.2 TCF), then shale gas (574.07 TCF), coal-bed methane (453.3 TCF), and shale oil 11.24 million tons. Exploitation can be done in various ways, such as dewatering for CBM, hydraulic fracking for tight and shale, and depressurization for methane hydrate. Once exploited, methane gas can be used for power plants, vehicle fuel, and industrial and household needs. Opportunities and challenges from various aspects, as well as applicable laws in Indonesia, are also discussed. In this light, the contribution of our study is to provide a comprehensive review of the characteristics, location, exploitation methods, opportunities, and challenges of utilizing unconventional oil and gas resources in Indonesia.

Abstract

This study aims at examining in what way and to what extent Indonesia can safeguard its energy security from a net zero perspective. To achieve the objective of this study, the current and projected figures of three variables of the country’s energy system—the total emissions of Kyoto gases, CO2 emissions per sector, and primary energy mix—up to the end of the century were calculated. To shed light on these variables, IMAGE 3.2, an Integrated Assessment Model (IAM) was used. Three scenarios that include CurPol, NDC, and Glasgow were reviewed. This study found that the country's reliance on finite fossil fuels becomes unavoidable, potentially causing Indonesia to miss its net zero target while also being vulnerable to energy crises. It is found that neither strategy described in the country’s current policies nor in its NDC are in line with the country’s net-zero target.This situation is exacerbated by the fact that Indonesia has not enshrined its net zero target in law, leaving the country’s net zero commitment merely as a proposal rather than a pledge. Thus, if Indonesia is committed to ensure its energy security while also meeting its net zero target, it becomes imperative for the country to advance energy efficiency measures, incorporate carbon capture and storage (CCS) technology to control the emissions of ffossil fuels, and significantly increase the shares of renewables (solar and biomass in particular) to at least 50%in the country's primary energy mix.

Abstract

In this study, the transformed zeolite from Lampung natural zeolite (LNZ) was used as a catalyst for the pyrolysis of a mixture of cassava tubers and rubber seed oil to produce bio crude oil (BCO). Transformation of Lampung natural zeolite into zeolite-A was attempted by adjusting the Si/Al ratios to 1.0, 1.5, and 2.0 transformed with and without aluminum addition and hydrothermal method with variation Si/Al ratio of 1.0; 1.5 and 2.0. The resulting products were specified as Zeo-C, Zeo-R1, Zeo-R1.5 and Zeo-R2.0. XRD analysis results show that Zeo-C and Zeo-R2 were transformed into zeolite-P, while zeolite-A, as targeted, was found in Zeo-R1 and Zeo-R1.5. SEM analysis results were also in accordance with XRD analysis results that showed the bipyramid crystal of zeolite-P in Zeo-C and Zeo-R2, while the cubic crystal of zeolite-A in Zeo-R1 and Zeo-R1.5. The BCO produced by using Zeo-C and Zeo-R1.5 as catalysts has the highest hydrocarbon content of 81% and 98%, respectively. Compared to previous studies, our study introduces an innovative approach by utilizing LNZ, a resource that has not been extensively explored, and combining cassava and rubber seed oil to produce bio-crude oil with a high hydrocarbon content. Our study contributes by promoting the use of underutilized biomass resources, potentially providing an environmentally friendly and economically viable alternative for BCO production.

Abstract

Municipal solid waste (MSW) stands out as a significant contributor to greenhouse gas emissions, with Indonesia ranking among the world's largest contributors. The Nationally Determined Contribution (NDC) commits Indonesia to minimize MSW emissions through renewable energy development, a central aspect of addressing the climate change crisis. In response, Presidential Regulation Number 35 of 2018 was introduced to vitalize these efforts. However, despite these initiatives, the existing legal framework has not adequately addressed the issue. This research aims to address two pivotal questions: How does Indonesian law regulate the conversion of waste into energy? To what extent do current regulations encompass Waste-to-Energy power plants? Employing a normative legal analysis, this study critically examines national legal instruments related to renewable energy, utilizing a statutory approach. Our findings underscore that current regulations concerning renewable energy lack effectiveness in ensuring availability, resilience, and national energy independence in a sustainable manner. Our study contributes to the existing body of research by delving into aspects of Waste-to-Energy regulation in Indonesia, an area that has not been extensively explored in previous studies.

Abstract

Natuna is one of the outmost islands in northern Indonesia. Natuna is vital as it delimits Indonesia’s territorial and deposits abundant energy resources. However, Natuna is also vulnerable, as it is adjacent to (and is partly located in) the South China Sea, a flash point in the region. As the sea is rich in natural resources, many countries around the sea are competing to control it, which leads to disputes. This study combines a literature review with interviews and finds that the risk of threats in the Natuna area encourages Indonesia to establish a military base there. The military base plays a role in securing Indonesia’s sovereignty over the Natuna area, including energy resources, an essential resource for the economy and development. This study proposes a new notion of ‘energy resource effects’ that influence the development of the situation and Indonesia’s decision to build a military base in the Natuna area. The energy-security nexus, thus, implies the close relationships between energy and security and how the two affect each other. Finally, this study also offers Indonesia’s perspective on securing its border areas, especially those rich in energy resources.
