Abstract

Energy is an important component for human survival and is highly dependent on the availability of energy. given the limited energy from mining materials available today is running low. In terms of production, global environmental issues and the depletion of fossil fuel reserves encourage various R&D on hydrogen production with water as raw material. In order to overcome the above, one solution is to take advantage of the existence of alternative forms of energy by utilizing electrical energy in the form of hydrogen gas stored in H2 which also comes from water (H2O) which can now be used for energy through the Water Electrolysis process where the best H2 gas production efficiency produced is 23.20% with a current variation of 10 A.

Penelitian ini membahas kebutuhan esensial akan air bersih dalam menghadapi krisis air bersih yang disebabkan oleh terbatasnya sumber air tawar dan peningkatan populasi. Proses penyaringan air menjadi solusi utama, dengan desalinasi sebagai metode utama menggunakan energi matahari. Studi ini meneliti penggunaan internal reflektor pada solar still double slope untuk meningkatkan produktivitas air tawar dan efisiensi. Simulasi Computational Fluid Dynamics (CFD) digunakan untuk menganalisis perpindahan panas dan aliran fluida dalam sistem tersebut. Penelitian dilakukan di Laboratorium Komputer, Teknik Mesin, Universitas Widyagama Malang, dengan variasi solar still standart/solar still tanpa reflektor dan solar still dengan penambahan internal refelektor (reflektor utara, reflektor selatan dan double reflektor/reflektor utara-selatan). Analisis CFD dapat dioptimalkan untuk meningkatkan produksi air dengan memeriksa pola distribusi temperatur pada solar still. Pemodelan solar still menggunakan aliran multiphase dengan tiga fase (udara, air, dan uap air). Simulasi ini akan fokus pada temperatur, massa jenis uap, dan kecepatan aliran fluida. Hasil simulasi menunjukkan bahwa penambahan internal reflektor meningkatkan transmisi energi matahari ke pelat penyerap, menghasilkan peningkatan penguapan air dan produksi uap air. Validasi simulasi dengan data eksperimen mengonfirmasi kinerja yang memuaskan. Dengan demikian, penelitian ini menyoroti potensi peningkatan efisiensi solar still dalam memproduksi air bersih menggunakan energi matahari.

Abstract

Indonesia has a high potential for solar energy, yet it is not optimally utilized. Additionally, the demand for hot water in Malang City is considerable. To meet this need, solar water heaters (SWH) can harness solar energy. However, one issue with SWH is that the mortar absorber plate has low thermal conductivity. This can be improved by adding copper powder to the mortar absorber plate. This study aims to identify the effects of adding copper powder to the absorber plate to enhance the performance of the solar water heater. The research compares mortar absorber plates with and without copper powder. Testing is conducted with varying flow rates. The study employs experimental methods, utilizing microscopic imaging, thermal conductivity tests, and SWH performance assessments. Microscopic analysis revealed that copper powder mixed with cement enhances the mortar. The addition of copper powder to the absorber plate (SWH.T) increases thermal conductivity by 25.16% compared to the standard version (SWH.S). Efficiency improvements for SWH.T over SWH.S at flow rates of 50, 150, and 250 ml/min are 24.20%, 9.91%, and 11.79%, respectively, with the highest efficiency for SWH.T at 250 ml/min reaching 45.56%.

Abstract

Waru tree bark fiber (hibiscus tiliceus) has potential as a natural fiber composite reinforcement, but further research is needed by focusing on the woven fiber model on the strength of the waru tree bark composite material. The problem to be studied is "The Effect of the Model of Waru (hibiscus tiliceus) Bark Fiber Weaving on the Tensile Strength of Composites". The specific objective of this study was to analyze the effect of the woven model of hibiscus tree bark (hibiscus tiliceus) on the tensile strength of the composite in terms of ultimate strength, strain, and modulus of elasticity. The urgency of this research is that the composite of hibiscus bark fiber without woven has a tensile load concentration that is very difficult to predict, so it is necessary to have a model of woven hibiscus bark fiber. The method used in this study is an experimental method. The composite molding process uses the vaccum infusion resin method with a variety of woven models, including: Plain 1-1, Twill 2-1, Satin 3-1, Basket 2-2. The matrix used is Bisphenol A LP-1Q resin and the reinforcement used is hibiscus tiliaceus bark fiber. The analysis carried out in this study, among others: Analysis of composite tensile strength and composite fracture analysis. The type of woven fiber affects the tensile strength of the composite. Therefore, it can be recommended that waru tree bark fiber is more suitable when using basket woven model fiber (2-2) than using unidirectional fiber model.
