Abstract

The scarcity of clean water is predicted to become a serious threat for Indonesia in the future, particularly in regions with low rainfall, and coastal regions with limited freshwater resources. This study examined clean water provision using seawater desalination technology in Sulamu Village, Kupang, East Nusa Tenggara, projected until 2032. The technology used was seawater desalination powered by Photovoltaic (PV) systems, which drive the Sea Water Reverse Osmosis (SWRO) process. This technology was proposed as a sustainable solution to meet the clean water needs of the region. The research included an analysis of water demand, adjusted for projected population growth, and an estimation of energy consumption from the PV-SWRO system. A geometric method was applied to project the population up to 2032, estimating approximately 8.210 residents. Based on this projection, the clean water demand was expected to reach 215.769 m³ per year, with energy consumption estimated between 496 and 1.554 MWh per year. Given the abundant solar energy potential in Sulamu Village, this technology is anticipated to provide a stable and environmentally friendly supply of clean water. The estimated data on water and energy needs is intended to serve as a reference for stakeholders in developing strategies that support the sustainability of renewable energy-based desalination programs in the future.

Abstract

Piston is one of the most crucial components of an engine. The primary raw material used in piston manufacturing is aluminum alloy, with silicon being the dominant element in the composition. As aluminum metal is increasingly used in modern times, its price has risen, leading to higher costs for piston components, given that aluminum is the main raw material for pistons. To address this issue, a method is needed to minimize the use of aluminum in piston manufacturing, which can be achieved by recycling used pistons and incorporating other materials, such as silicon carbide (SiC). The addition of silicon carbide (SiC) was varied at 15%, 20%, and 25%. Hardness testing results showed that the higher the SiC content, the greater the hardness value obtained. As the hardness value increases, the wear resistance of the material improves. Based on this study, the addition of 15% SiC is optimum to achieve performance equivalent to that of a new piston of brand X.
