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.

Abstract

Nilai daya jual rendah dan keberadaan serat sabut kelapa yang melimpah di pesisir laut terutama di daerah Klirong, Kebumen. Serat sabut kelapa digunakan pada beberapa produk industri kreatif seperti topi, tas, dan keset lantai. Kayu balsa banyak digunakan pada berbagai kebutuhan furnitur rumah karena memiliki massa yang ringan dan harga murah. Program Pengabdian Unggulan Universitas ini bertujuan untuk melakukan pendampingan warga  dalam pengembangan material serat sabut kelapa untuk pembuatan produk meja dan kursi menggunakan papan komposit sandwich yang berlokasi di Tuguran, Magelang Utara. Bahan komposit digunakan pada program  pengbadian ini yaitu serat sabut kelapa, kayu balsa, resin unsaturated polyester serta katalis. Rangka meja dan kursi menggunakan material baja hollow ST37. Metode pembuatan produk komposit sandwich berpenguat serat sabut kelapa fraksi volume serat 20% dengan core kayu balsa tebal 10 mm dibuat dengan metode cetak tekan menghasilkan energi serat 0,87 J dan ketangguhan impak 0,0176 J/mm². Perakitan rangka meja dan kursi menggunakan metode pengelasan Shielded Metal Arc Welding (SMAW) dengan arus 100 A. Hasil pembuatan produk menunjukkan bahwa komposit sandwich dengan metode cetak tekan menghasilkan papan komposit sandwich dengan sedikit void dan tidak terjadi delaminasi atau cacat. Pengelasan minim cacat pada parameter  arus 100 ampere, sehingga rangka kursi kuat menahan beban sampai 100 kg yang sudah diuji coba diduduki langsung oleh warga. Pendampingan pembuatan meja dan kursi komposit memberikan manfaat berupa kemampuan warga dalam soft skill dan hard skill dalam pembuatan produk meja dan kursi komposit sandwich yang memiliki daya jual dan kebermanfaatan tinggi.
