Abstract

Micro-hydro power plants take advantage of the energy potential of low-head airflow. with the development of technology that can support it, namely the Archimedes screw turbine as the driving force. Various parameters must be considered to determine the performance of micro hydro power plants with Archimedes screw turbines. A design is carried out with a discharge parameter flow rate of 2 l/s, a turbine slope of 300, and an immersion level variation of 0.3, 0.5, and 0.7, where the final result shows the value of torque, hydraulic power, mechanical power, generator, and efficiency, which decreases with the level of water immersion in the last blade.

Abstract

Teknologi panel surya memungkinkan konversi cahaya matahari menjadi energi listrik. Akan tetapi, ada masalah yang dapat muncul pada kinerja panel surya, misalnya peningkatan suhu panel surya melebihi batas kerjanya sendiri. Suhu yang semakin meningkat akan membuat kinerja panel surya semakin berkurang. Maka, penting menjaga suhu panel surya sangat diperlukan agar performanya tetap optimal. Penelitian ini dilakukan untuk mengetahui pengaruh delay timing back and front surface spray cooling terhadap temperatur rata – rata, daya output, dan pengoptimalan energi panel surya. Pengujian ini menghasilkan temperatur panel surya sangat menurun ketika delay timing spray 10 menit senilai 58,95°C, ketika delay timing spray 20 menit senilai 70,78°C, sedangkan ketika delay timing spray 30 menit senilai 78,63°C. Metode pendinginan yang dilakukan selama 1 menit dengan variasi delay timing spray 10 menit, 20 menit, dan 30 menit. Uji eksperimental ini dapat menurunkan suhu panel surya, pada delay timing spray 10 menit menjadi 58,95°C, pada delay timing spray 20 menit menjadi 70,78°C, dan pada delay timing spray 30 menit menjadi 78,63°C. Metode pendinginan dilakukan selama 1 menit dengan delay timing spray yang bervariasi yaitu 10 menit, 20 menit dan 30 menit. Melalui pengujian ini juga diperoleh nilai energi total. Apabila delay timing spray 10, 20 dan 30 menit masing-masing sebesar 8,61 x 10-3 kWh (30982,06 Joule), 8,03 x 10-3 kWh (28890,32 Joule) dan 7,61 x 10-3 kWh (27408,06 Joule). Kesimpulan dari penelitian yang telah dilakukan adalah delay timing spray yang paling optimal delay timing spray selama 10 menit dengan suhu rata-rata sebesar 58,95°C, dan optimalisasi energi terbaik adalah dengan energi total sebesar 30982,06 Joule atau 8,61 x 10 -3kWh.

Abstract

Sungai Pitung Village, Barito Kuala Regency, is classified as a developed village based on the Village Development Index, yet empirically faces structural problems. Economic dependence on tidal rice monoculture, rice husk waste openly burned, and underutilized vacant land are the main issues. The social project of the Jerami Peduli Team employed a Participatory Rural Appraisal approach with two main interventions: processing rice husk waste into liquid smoke using pyrolysis technology, and cultivating loofah on vacant land. Cost-benefit analysis shows the program is economically feasible with positive net benefits. Beyond financial benefits, the program enhances community capacity, environmental awareness, and creates sustainable productive village assets. This project offers an adaptive and applicable model for wetland-based village empowerment.

Abstract

In Indonesia, basic energy needs still depend on natural gas, coal, and petroleum until their availability is decreasing. Bagasse and coconut shell charcoal briquettes offer the best solution as an alternative energy source that is environmentally friendly and abundantly available. This study aims to analyze the effect of variations in the composition of bagasse (AT) and coconut shell charcoal (TK) using tapioca starch adhesive on the characteristics of the briquettes. The compositions tested were 25% AT : 75% TK; 30% AT : 70% TK; 35% AT : 65% TK. The briquettes were evaluated based on parameters such as calorific value, carbon content, ash content, water content, volatile matter content, and combustion rate. The results showed that the briquettes with composition variations of 25% bagasse and 75% coconut shell charcoal had a calorific value of 5721.63 cal/g, carbon content of 64%, ash content of 8%, water content of 7.56%, volatile matter content of 28%, and a combustion rate of 0.19 grams/minute. However, only the water content value that meets SNI 1683/2021 quality 1 is ≤ 8%

Abstract

Constructing a small-scale hydroelectric power station that can run efficiently at a head lower than 10 m is one possible method for reducing the impact of the electricity crisis in remote areas of Indonesia. The Archimedes Screw turbine is one type of turbine that is ideal for discharges below 10 m. In this study, the simulation results show that the value of Turbulences Kinetic Energy is directly proportional to the increase in flow rate but inversely proportional to the level of immersion. This type of turbine is unless well in Indonesia due to a lack of information regarding the application of low head power plants. The turbine model that is suitable for the low head is investigated in this study. Before being tested, the turbine is first designed theoretically and then numerically evaluated. With discharges of 1 l/s, 2 l/s, and 3 l/s and turbine immersion levels of 30%, 50%, and 70%, ANSYS CFD (Computational Fluid Dynamic) software was used to investigate flow rate and level of immersion in the turbine. According to the investigation findings, the discharge has a considerable impact on the turbine's movement; the higher the flow rate, the higher the power to the turbine, which produces a torque on the turbine. The simulation findings indicate that the value of Turbulence Kinetic Energy is proportional to the increase in flow rate but inversely proportional to the level of immersion.
