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.

Abstract

The phenomenon of mixing turmeric in water is widely used as a simple science experiment to introduce basic concepts of physics and chemistry. However, the physical behavior of curcumin—the primary pigment in turmeric—is complex and influenced by various physical principles, including diffusion, optics, thermodynamics, and molecular dynamics. This literature review aims to synthesize and analyze scientific findings related to turmeric–water interactions from the perspective of fundamental physics. By reviewing national and international research articles, this study identifies the diffusion mechanism of curcumin as described by Fick’s Law, its optical properties responsible for light absorption and color appearance, and the physical factors—such as temperature, pH, and light exposure—that affect curcumin stability in aqueous media. Additionally, the review highlights the roles of Brownian motion and solute–solvent molecular interactions in explaining the microscopic behavior of curcumin particles. The findings indicate that the “turmeric in water” phenomenon is not merely a simple mixing process but involves complex physical dynamics suitable for use as phenomenon-based learning material in science education. This study provides a strong theoretical foundation for the development of educational experiments and opens avenues for future research on the physical characteristics of natural pigments.

Abstract

This article presents the results of an in-depth literature review on radiocarbon dating, tracing its development from the earliest stages. Particular emphasis is placed on the role of carbon-14 (¹⁴C) in determining the age of materials and on how dendrochronological calibration can enhance accuracy. The discussion also focuses on the decay of carbon-14 isotopes and their half-life, the methods and principles underlying radiocarbon dating, dendrochronological calibration, and other applications of radiocarbon dating in age determination. In conclusion, the article highlights the significant contributions of radiocarbon dating and dendrochronology in addressing critical challenges in archaeological research, thereby enabling scholars to gain a deeper understanding of natural history and human culture.

Abstract

The use of lead-based radiation shielding materials continues to face increasing rejection due to their toxicity, substantial weight, and incompatibility with sustainability principles. Recent research has driven the development of safer and lighter alternative materials that provide radiation attenuation effectiveness comparable to, or even surpassing, that of lead. This review article summarizes advancements in geopolymers, environmentally friendly heavy concrete, and polymer composites enriched with heavy metals as lead-free radiation shielding materials. Lattice vibration interactions, particularly optical phonons, are also discussed due to their growing relevance in enhancing photon-energy absorption in polymer composites. This review is intended to provide a comprehensive overview of emerging trends, underlying mechanisms, and the implementation potential of next-generation alternative radiation shielding materials
