Abstract

Pressurized water reactors (PWRs) are one of the most dominant types of nuclear power plants that have been operated commercially to produce electricity in the world. The purpose of this study was to perceive a three-dimensional (X-Y-Z) core design of long-life PWR using Thorium-Uranium dioxide ((Th-U)O2) fuels with the addition of Gadolinium (Gd2O3) and Protactinium-231 (Pa-231) as the burnable poisons. A combination of Thorium and enriched Uranium fuels have a higher conversion ratio than other fuels, therefore can guarantee the reactor to operate longer. The burnable poison isotopes could be used to reduce excess reactivity due to the very high thermal neutron absorption cross-section. For core geometry analysis, a three-dimensional (X-Y-Z) geometry and a fuel volume fraction of 40% were applied. The computer code of SRAC 2006 from the Japan Atomic Energy Agency (JAEA) and the JENDL 4.0 as a nuclear data library were used for calculation. In this study, different fractions of Uranium dioxide, Uranium-235, Gadolinium, and Protactinium-231 in fuel were carried out. The result of this study was a three-dimensional core design of 800 MWt PWR using 60% Uranium dioxide fuel with enriched Uranium-235 of 12%-11% and the addition of 0,025% Gd2O3 and 1,0% Pa-231 which could operate for ten years without refueling. This research is expected to be a reference for long-life PWR design using the Thorium and Uranium fuel cycles.

Abstract

Background: This study analyzes the cultural relations of the Baduy community in their efforts to conserve nature using a qualitative approach based on ethnography. Methods: Data was collected through non-participatory observation and unstructured interviews with nine informants from the Baduy indigenous community in Banten. The analysis uses social ecology theory and customary law. Findings: The results show that the Baduy community consistently practices norms, spirituality, and nature conservation that have been passed down by their ancestors, even as globalization and modernism sweep through. The findings show that the Baduy community possesses ecological wisdom that functions as a form of local environmental governance, integrating spiritual values with environmental ethics. Their resistance to modernization and industrialization is not a rejection of progress, but a conscious effort to maintain the balance between humans and nature in accordance with traditional values. Conclusion: This research, grounded in local wisdom, not only deepens readers' understanding of the Baduy indigenous community's role in preserving cultural identity while conserving nature but also aids in the design of government policies. Novelty/Originality of this article: This research expands on previous studies by highlighting the spiritual aspect of the Baduy indigenous community as an important ecological actor that has received little attention in studies of indigenous ecology.

Abstract

This study aims to analyse the role of Pancasila as the nation’s philosophy in ensuring justice and equality for minority groups, particularly nonagama, who have long received limited attention in both academic discourse and public policy. The research employs a qualitative approach using a literature study method and thematic as well as critical document analysis of discourses on nonagama and interpretations of Pancasila’s principles, especially the first precept. The findings reveal three main obstacles faced by nonagama groups in attaining justice and equality: (1) the exclusive interpretation of Pancasila’s first precept, (2) a prevailing social paradigm that links morality with religiosity, and (3) low public awareness of pluralistic values. These findings imply the need for a reconstruction of understanding Pancasila in a more inclusive and open manner, so that it can guarantee constitutional rights for all citizens without discrimination. The originality of this research lies in its focus on nonagama groups from the perspective of Pancasila—an area rarely addressed in previous studies—thus contributing new insights to the discourse on pluralism, inclusivity, and human rights in Indonesia.

Abstract

Telah dilakukan simulasi pada Molten Salt Fast Reactor (MSFR) berdaya 100 MWth untuk menganalisis pengaruh bentuk dan ukuran teras terhadap kinerja neutronik. Penelitian ini menggunakan kode komputasi SRAC (Standard Thermal Reactor Analysis Code System) yang dikembangkan oleh JAEA (Japan Atomic Energy Agency). Analisis dilakukan terhadap 9 variasi bentuk dan ukuran teras pada teras MSFR silinder dua dimensi (2-D) dengan peninjauan terhadap parameter neutronik yaitu faktor multiplikasi efektif,. Perhitungan neutronik dilakukan dengan mengatur komposisi bahan bakar dalam teras. Hasil perhitungan menunjukkan bahwa seluruh variasi model teras menghasilkan nilai faktor multiplikasi efektif di atas 1,0 pada awal masa operasi reaktor. Model teras C1 (volume teras 6 m3, bentuk teras tall) merupakan model teras yang paling baik dalam mempertahankan kekritisan reaktor dengan reactivity swing sebesar 0,0721. A simulation of 100 MWth Molten Salt Fast Reactor (MSFR) has been carried out to analyze the influence of core shape and size to its neutronic performance. This research used computational code SRAC (Standard Thermal Reactor Analysis Code System) developed by JAEA (Japan Atomic Energy Agency). Analysis has been done to 9 variation of core shape and size on two-dimensional (2-D) cylinder of  MSFR in terms of neutronic parameter such as the effective multiplication factor with arrangement of fuel composition. The neutronic calculation shows that all of core type bring out the value of effective multiplication factor above 1,0  in the beginning of reactor operation. C1 is the most optimum core model because it can maintain the criticality of the core reactor with reactivity swing value of 0,0721.

Abstract

Corruption within Indonesia’s education sector ranks among the most frequently identified and prosecuted cases by the Corruption Eradication Commission (KPK). Education itself is a vital sector for human resource development; therefore, corruption within it poses a direct threat to the development process. This concern forms the foundation for this study, which aims to analyze the current realities, causes, and solutions to address corruption in Indonesia’s education sector. The findings of this article may serve as strategies to mitigate and prevent potential corruption within this critical sector. This study employs a literature review with a qualitative approach, drawing primarily on data from books, journals, institutional reports, accredited websites, and other relevant documents. Data analysis was conducted after compiling and reviewing various literature sources, from which insights and conclusions were derived. The results reveal a pervasive corruption problem in the education sector, supported by diverse data points. The causes of corruption are multifaceted, encompassing personal motives, societal and cultural influences, weak law enforcement and oversight, government negligence, and inadequate institutional management. Consequently, the proposed solutions are categorized into three dimensions: individual/personal, environmental/cultural, and institutional.

Abstract

Perkembangan teknologi digital telah menghadirkan tantangan baru dalam perlindungan hak cipta, khususnya untuk karya digital seperti musik, video, dan aplikasi. Artikel ini menganalisis sistem perlindungan hak cipta di Indonesia dan Korea Selatan melalui pendekatan komparatif. Di Indonesia, perlindungan hak cipta diatur melalui Undang-Undang Nomor 28 Tahun 2014, yang mendirikan Lembaga Kolektif Manajemen Nasional (LKMN) untuk mengelola royalti. Namun, tantangan berupa rendahnya kesadaran masyarakat, keterbatasan sumber daya, dan koordinasi yang kurang masih menjadi hambatan. Sebaliknya, Korea Selatan memiliki pendekatan yang lebih efektif melalui Korea Music Copyright Association (KOMCA), sebuah organisasi nirlaba yang dikelola oleh pemegang hak cipta itu sendiri. KOMCA secara aktif melisensikan karya, mendistribusikan royalti, dan meningkatkan kesadaran publik tentang pentingnya perlindungan hak cipta. Perbandingan ini menunjukkan bahwa sistem hukum yang lebih terstruktur, seperti di Korea Selatan, dapat menjadi model untuk meningkatkan efektivitas perlindungan hak cipta di Indonesia. Reformasi hukum, edukasi masyarakat, dan kerja sama internasional diidentifikasi sebagai langkah strategis untuk meningkatkan perlindungan hak cipta di era digital.
