Abstract

The Hydride–Dehydride (HDH) method is a critical technology in uranium processing, capable of improving the efficiency and quality of nuclear fuel through a more precise embrittlement process compared to conventional techniques. This technology ensures uniform particle size and minimizes material loss during fabrication. This study was conducted using a literature review approach, supported by experimental data obtained during a 2022 internship at the Research Center for Nuclear Fuel Cycle and Radioactive Waste Technology (PRTDBBLNR). The focus of the investigation was the characterization of uranium–molybdenum (U-Mo) alloy before and after the HDH treatment process. The results indicate that heat treatment at 500 °C for 5 hours followed by annealing significantly increases the hardness of the U-Mo alloy. A phase transformation was also observed, indicated by the presence of α-U in all post-treatment samples. Nevertheless, the density of the alloy showed no substantial change. The HDH process successfully produced high-purity U-Mo powder at various molybdenum concentration levels. However, increasing Mo content resulted in lower powder density. The morphology of U-7Mo powder exhibited flake-like shapes with a rough surface, which is favorable for further fabrication in advanced fuel element production. Overall, these findings reinforce the relevance and significant potential of HDH technology in supporting advanced nuclear reactor fuel production and strengthening national nuclear energy security in a sustainable manner.The Hydride–Dehydride (HDH) method represents an important innovation in uranium processing to improve the efficiency and quality of nuclear fuel. This technology enables a more precise embrittlement of uranium compared to conventional methods such as milling and crushing, resulting in more uniform particle size and reduced material loss throughout the process. This study adopts a literature-based approach supported by practical work conducted at the Center for Research on Nuclear Fuel Cycle Technology and Radioactive Waste Management (PRTDBBLNR) in 2022, in order to evaluate the effectiveness of HDH in strengthening nuclear energy security in Indonesia. The analysis shows that HDH improves the microstructural quality of uranium and enhances processing yield by minimizing waste generation. These advantages highlight the high relevance of HDH technology in supporting the development of Generation IV nuclear reactors, which emphasize efficiency and sustainability within the fuel cycle. However, its implementation in Indonesia still faces challenges, particularly in terms of industrial infrastructure readiness, safety regulations, and nuclear material protection. Therefore, strategic policies are required to promote further research and technological investment, as well as strong collaboration between academia, government, and industry. Integrating HDH into the national uranium processing roadmap has the potential to establish this technology as a key pillar in ensuring a sustainable nuclear fuel supply and enhancing Indonesia’s energy security in the future.

Abstract

The escalating national energy demand and Indonesia's substantial reliance on fossil fuels underscore the imperative for the development of more sustainable alternative energy sources. Conversely, the magnitude of waste management challenges in DKI Jakarta persists, exerting an additional strain on the operational capacity of the Bantargebang TPST. Refuse Derived Fuel (RDF) is regarded as a strategic solution that can address the need for waste reduction and the provision of alternative energy. The objective of this study is to analyze the implementation of the RDF Plant Rorotan trial in DKI Jakarta using the implementation theory approach of Mazmanian & Sabatier and Allan McConnell's Policy Failure Theory model (2010). The methodological approach employed is descriptive qualitative, with data collection through documentation studies and observation.  The results of the study indicate that RDF Rorotan faces various technical, institutional, and social obstacles. According to the findings of Mazmanian & Sabatier's analysis, the characteristics of the problem, the clarity of policy objectives, coordination between relevant actors, and social environment support proved inadequate for achieving effective implementation. The presence of technical challenges, including elevated moisture content in waste, unpublished RDF quality, the ambiguity of off-takers, and complaints from residents regarding odors and health disturbances, suggests a suboptimal level of implementation readiness. McConnell's analysis corroborates the finding that RDF Rorotan is in a position of precarious success, which has resulted in policy failure in three areas: process, program, and politics. Indicators of early implementation failure include declining operational capacity, community resistance, and weakening policy legitimacy. The study's findings indicate that Rorotan RDF has not adequately fulfilled its designated role as a waste management solution and an energy alternative for national energy security. To optimize the potential of RDF, there is a necessity for improvements in quality standards, strengthened coordination, data transparency, and comprehensive environmental management strategies.

Abstract

Urban energy resilience has become a critical challenge for Southeast Asian megacities amid rapid urbanization, climate induced hazards, and increasing dependence on centralized energy systems. While existing studies predominantly emphasize technical reliability, the governance dimension of urban energy resilience remains insufficiently theorized. This study proposes a conceptual framework that integrates the four dimensions of energy security, Availability, Accessibility, Affordability, and Acceptability (4A) with the OECD’s Seven Multilevel Governance Gaps to examine how institutional structures shape urban energy resilience. This qualitative systematic literature review applies the framework to a comparative analysis of Jakarta, Manila, and Bangkok. The findings reveal contrasting resilience profiles across the three cities. Manila demonstrates low adaptive capacity due to fragmented governance and high reliance on imported energy. Jakarta exhibits dependent resilience, characterized by a stable supply but limited local autonomy under centralized energy governance. Bangkok demonstrates relatively strong resilience, supported by higher institutional capacity, although constrained by policy inertia and coordination gaps. The study concludes that urban energy resilience is driven primarily by governance performance rather than technical capacity alone. This framework provides a policy oriented analytical tool to strengthen urban energy resilience in developing countries.

Abstract

Baganyi adalah proses awal dari perpisahan untuk memberi jeda bagi pasangan yang berkonflik. Proses baganyi diawali dengan usaha untuk menghindari konflik pasangan dalam rumah tangga dengan kepergian suami dari rumah secara resmi saat terjadi perselisihan. Praktik ini memungkinkan pasangan untuk menenangkan diri dan menghindari tindakan gegabah, yang dapat berpotensi memicu kekerasan dalam rumah tangga (KDRT). Tujuan penelitian ini adalah untuk mengkaji bagaimana praktik baganyi berfungsi sebagai mekanisme proaktif dalam menjaga ketahanan rumah tangga di masyarakat Minangkabau dengan perspektif hifz an-nasl. Penelitian ini menggunakan pendekatan kualitatif dengan jenis field research yang bersifat deskriptif-analisis. Sumber data primer berasal dari hasil wawancara mendalam di Kecamatan Palembayan, Kabupaten Agam terhadap informan yang dipilih dengan teknik purposive sampling. Analisis data dilakukan secara kualitatif dengan pendekatan teori ketahanan keluarga dari Froma Walsh dan teori hifz an-nasl. Hasil penelitian ini menyimbulkan bahwa tradisi baganyi yang dilakukan dalam masyarakat Palembayan mencerminkan sistem ketahanan keluarga yang kuat menurut kerangka Froma Walsh. Tindakan ini memungkinkan keluarga untuk menstabilkan sistem di tengah krisis dan memperoleh kembali kekuatan melalui intervensi adat, sehingga tujuan hifz an-nasl tercapai melalui pemulihan fungsi keluarga yang lebih kokoh. Implikasi dari penelitian ini akan memberikan contoh bahwa kearifan lokal mampu menjadi sumber daya sosial yang efektif dalam menjaga keutuhan keluarga.

Abstract

Indonesia’s energy security faces structural challenges due to the dominance of coal in the national energy mix, leading to sustainability risks and increased greenhouse gas emissions. To achieve the 23% renewable energy target by 2025, the government promotes biomass utilization through co-firing in coal-fired power plants. However, its implementation remains constrained by limited sustainable biomass supply and inefficient supply chain systems. This study aims to formulate an optimal allocation strategy for woodchip production in Java as a primary biomass source to support co-firing implementation. The methodology integrates spatial analysis using the Center of Gravity approach and SWOT analysis to develop an integrated development strategy. Key indicators include biomass availability, transportation accessibility, proximity to demand centers, and policy support. The results indicate that Java has a biomass residue potential of 143.58 million tons annually, yet faces a significant land gap of 189,849 hectares for energy plantations. Supply chain optimization reduces delivery time by up to 44% and logistics costs by 38%, with an optimal distribution radius of 80 km serving 16 coal-fired power plants with a total capacity of 14,645 MW. The proposed integrated strategy includes capacity expansion, land intensification, feedstock diversification, and supply chain efficiency through multi-stakeholder collaboration. Overall, the strategy ensures a sustainable biomass supply of 10.2 million tons by 2025 without additional deforestation. The integration of woodchip in co-firing contributes to a 15% reduction in CO₂ emissions and improved plant efficiency, thereby accelerating energy transition, strengthening energy security, and supporting Indonesia’s Net Zero Emission 2060 target.
