Abstract

The transition to clean energy is an urgent global agenda to address climate change and fulfill Net Zero Emission (NZE) commitments, including in Indonesia which targets NZE by 2060. This article analyzes the strategic role of nuclear energy as a low-carbon energy source in supporting the clean energy transition. A literature review of the latest scientific sources discusses the basic principles of nuclear physics in fission reactions, the advantages of nuclear energy over fossil energy in reducing carbon emissions, and the challenges and prospects for developing nuclear technology. The analysis shows that nuclear energy has significant potential to substantially reduce carbon emissions, ensuring energy supply security, and acting as a complement to intermittent renewable energy sources. However, safety issues, radioactive waste management, and initial investment costs are still major challenges that require technological innovation and strict regulations. Thus, nuclear energy deserves to be considered a key pillar in Indonesia's decarbonization strategy and achievement of NZE, provided that it is accompanied by continuous efforts to improve safety standards and risk management.

Abstract

Food preservation is a crucial aspect in maintaining the quality, safety, and nutritional value of products, particularly in Indonesia with its rich diversity of food resources. Conventional methods such as drying, salting, and freezing are still dominant but have limitations in preventing food spoilage caused by microbiological and environmental factors. One emerging innovation in modern preservation technology is the use of gamma irradiation. This technology effectively eliminates pathogenic microorganisms without damaging the physical and chemical quality of food products. This literature study aims to understand the working mechanism of gamma irradiation, its impact on food, and its role in enhancing food production in Indonesia. Gamma irradiation uses radiation from radioactive isotopes such as Cobalt-60 to damage microbial DNA, thereby extending product shelf life. The technology is considered safe, leaves no residues, is energy-efficient, and environmentally friendly. However, its application in Indonesia remains limited due to a lack of public awareness and persistent negative stigma surrounding nuclear technology. Public education is key to increasing societal acceptance of food irradiation. With proper implementation, gamma irradiation technology holds significant potential in reducing food waste, enhancing food safety, and supporting national food security.

Abstract

Dating ancient human fossils is a crucial component in reconstructing hominin evolution and migration. This article reviews the basic principles and applications of various radiometric dating techniques, including radiocarbon (14C), potassium-argon (K-Ar), uranium-series (U-Pb, U-Th), and advanced methods such as accelerator mass spectrometry (AMS) and laser ablation ICP-MS through a systematic literature review of primary and secondary sources. Data synthesis shows that the 14C method is effective for materials up to ~50,000 years old, at the same time K-Ar and U-Pb/Th are suitable for older geological age ranges (hundreds of thousands to millions of years). Improved accuracy is supported by submicroscopic isotope analysis technology; however, the challenges of sample contamination and limited amounts of authentic material still limit its widespread application. These findings underscore the importance of a multi-method approach to obtain reliable absolute ages for human fossils and provide recommendations for refining sample handling procedures and integrating relative data (stratigraphy, magnetostratigraphy) for more comprehensive temporal contextualization.

Abstract

The use of long-lived isotopes as an energy source in satellite electrical power systems has become a significant focus in modern space technology. One such isotope, Plutonium-238, generates energy through radioactive decay over an extended period, enabling satellites to operate in extreme environments with minimal sunlight. This study aims to gather and analyze literature on the application of long-lived isotopes to enhance the sustainability and reliability of satellite power systems. The method employed is a literature review, which involves examining articles from various academic databases. The data sources consist of six scientific articles and one book relevant to the topic. Findings indicate that the use of long-lived radioactive isotopes, such as Plutonium-238 and Americium-241, has proven effective in sustaining satellite electrical power systems, particularly through Radioisotope Thermoelectric Generator (RTG) technology. These isotopes generate heat through radioactive decay, which is subsequently converted into electrical energy, allowing satellites to operate in extreme conditions and without relying on solar exposure.

Abstract

This article analyzes the development potential of a Small Modular Reactor (SMR) as a solution energy transition in Indonesia to reduce dependence on fossil fuels, especially oil and coal. Through a literature review, the article compares SMR performance with Generator Electricity Steam Power (PLTU) in terms of energy capacity, impact, and additional applications such as water desalination and hydrogen production. The results showed that the fourth generation SMRs (HTGR, MSR) have high-efficiency electricity, more tall 40-50%, compared to Steam Power Plant (30-40%), with low carbon (3,676-5,388 g CO2 equivalent/kWh for SMR and 1,000 g CO2 /kWh for PLTU). SMR is also capable of producing desalinated water at the lowest cost (USD 0.398/m3 or Rp 6,574/m3) and sustainable hydrogen (9.63 g/kWh). However, adoption of SMR in Indonesia faces complex challenges, including high FOAK costs, regulations that are not yet adaptive, limited supply of special fuels, gaps in skilled human resources, and community resistance regarding waste. Nuclear. This article recommends regulatory revisions, financial incentives based on KPBU schemes, HR training through international collaboration, and public education strategies to increase social acceptance. With integrated policies, SMR has the potential to become a pillar of Indonesia's energy transition towards decarbonization and sustainable energy security.

Abstract

This study investigates the groundwater potential in the Le Cendekia Islamic Boarding School area, Gowa, using the Vertical Electrical Sounding (VES) method with a Schlumberger configuration along a 240 m survey line. The work was motivated by recurring freshwater scarcity despite previous unsuccessful drilling attempts. Field measurements of current, potential difference, and electrode spacing were processed using Microsoft Excel and inverted with Progress software to generate a 1D true resistivity model. The apparent resistivity curve shows a steady increase with depth, indicating a transition from conductive near-surface materials to more resistive formations. The inversion results delineate nine subsurface layers, with the upper 25 m dominated by alluvium and wet clay that function as aquitards due to their low permeability. Below these units lies a conductive saturated clay layer that further restricts vertical groundwater flow. A significantly more resistive layer at approximately 25–30 m is interpreted as fractured or partially consolidated sandstone, suggesting enhanced permeability and potential groundwater storage. Based on these findings, the most favorable drilling depth for preliminary groundwater exploration is recommended at 25–30 m. This study provides essential baseline information to guide groundwater development in the Le Cendekia area.

Abstract

The use of nuclear technology, particularly irradiation using gamma rays, offers an effective solution for increasing the shelf life of marine fish. This article discusses the physics behind the use of gamma rays from Cobalt-60 and Cesium-137 sources in food irradiation. Cobalt-60 is the most commonly used source of gamma rays because it emits high-energy radiation that effectively penetrates foodstuffs, including marine fish. The irradiation process works by damaging the DNA of microorganisms that cause spoilage and disease through ionizing radiation, thereby extending the shelf life of fish without compromising nutritional quality and taste. The use of Cesium-137, although less common, is also discussed as an alternative source of gamma rays. Irradiation with gamma rays from Cobalt-60 and Cesium-137 has been proven effective in killing pathogenic microorganisms and maintaining the freshness of marine fish for longer. Challenges in implementing this technology, such as initial costs and consumer education, need to be addressed to maximize its benefits. The future prospects for food irradiation are very promising with further research and collaboration between sectors.

Abstract

Nuclear energy has become a promising alternative in overcoming dependence on fossil fuels and improving energy efficiency. In this article, the author discusses the process of generating safe and environmentally friendly nuclear energy. Nuclear energy is produced through atomic nucleus reactions, such as nuclear fission, which create large amounts of energy. Nuclear reactors, such as nuclear power plants, utilize air as both a coolant and a moderator, generating electrical energy through a heat conversion process. The advantages of nuclear energy include its high energy density, better energy efficiency, and minimal greenhouse gas emissions. However, nuclear power plants also have disadvantages such as the risk of nuclear accidents and the high-level nuclear waste they produce. In summary, nuclear energy offers an effective solution for improving energy efficiency and reducing dependence on fossil fuels, but it must be balanced against its associated drawbacks and risks.
