Abstract

Lampung, a province in Indonesia with a robust agricultural and livestock sector, exhibits substantial potential for biogas production. Biogas, derived from agricultural residues and animal manure, such as cow and goat dung, presents a sustainable alternative to conventional fossil fuels. Given the escalating global energy demand and environmental concerns, this study endeavors to quantify the biogas potential in Lampung, particularly focusing on the conversion of livestock manure into energy. Employing the QGIS application, this research maps the geographical distribution of biogas potential. Findings indicate that, with optimized management practices, Lampung could produce hundreds of thousands of tons of methane annually, sufficient to partially meet the energy requirements of local households and industries. Beyond energy generation, biogas production can stimulate economic growth, enhance farmers' incomes, and mitigate greenhouse gas emissions. However, the widespread adoption of biogas technology in Lampung is contingent upon addressing several challenges, including technological limitations, public awareness, and the need for conducive policy frameworks.

Abstract

Wind turbines are one of the environmentally friendly conversion tools with one of the main components being blades. Jember is one of the districts of East Java. The average wind speed in Indonesia is relatively low ranging from 3 m/s to 5 m/s. The potential for wind in Indonesia is available almost all year round, so there is a possibility of developing technology to utilize this energy with some previous limitations. Windmill modifications need to be made that are adapted to low wind speed conditions to be able to produce optimal electrical energy. Therefore, a design of HAWT (Horizontal Axis Wind Turbine) blades using mahogany wood material was made by testing the current, voltage, and wind speed system at Asmara Beach, Jember. This study aims to design and evaluate the performance of a taperless bladed wind turbine made from mahogany wood as an alternative environmentally friendly material. The turbine design is optimized through numerical simulation to achieve maximum efficiency. The results show that wind turbines made from mahogany wood have potential as a promising source of renewable energy, especially in areas with moderate wind speeds.
