Abstract

The use of wind energy as one of the producers of electrical energy is done by converting mechanical energy into electrical energy from wind turbines, one of which is the savonius wind turbine. Savonius wind turbines in use are able to work at low wind speeds. This study aims to evaluate the potential of wind energy that can be generated by optimization in savonius wind turbines by measuring the power generated by varying the gap distance between Balde and turbine shafts and analyzing the most optimal power as a source of power generation on the coast of Sarmi Regency, Papua Province. The analysis method in this study is field surveys, wind speed measurements, power optimization, BHP and tool efficiency carried out with variations in the distance between the blade and turbine shaft, namely 5 cm, 10 cm and 15 cm. The results of this study stated that the most optimal and stable results on the power generated by the turbine as well as the BHP value and the best tool efficiency were a distance variation of 15 cm with an average power value produced (P0) of 15.55 Watts, an average BHP value of 0.56 Watts and an average efficiency value of 7.59%.

Abstract

Organic waste management in Indonesia faces significant challenges due to the high greenhouse gas emissions produced. In 2020, greenhouse gas emissions from waste management in Indonesia especially the waste sector contributes around 3.2% of total global emissions. The use of organic waste shredders is one solution to minimize waste volume; althought still heavily rely on conventional energy, which is not environmentally friendly. This study aims to evaluate the implementation of solar photovoltaic (PV) technology in organic waste shredding machines to enhance energy efficiency and reduce environmental impacts. An experimental approach was used in this research. Data were collected through measurements of energy generated by the solar cells, energy consumed by the machine, and the organic waste shredding output processed into compost fertilizer. The results showed that use of solar cells could generate an average of 5.8 kWh of energy per day, with machine energy efficiency reaching 72%. Compared to conventional energy, the use of solar cells increased the shredder machine's productivity to 25 kg/hour and reduced greenhouse gas emissions by up to 70%. Additionally, machine operating time increased by 20% compared to machines using conventional energy.  This increase is due to the solar cell technology itself. In conclusion, application of solar cell technology in organic waste shredders not only improves operational efficiency but also significantly contributes to carbon emission reduction. The research  contribution is to offer concrete solutions that support the achievement of national and global carbon emission reduction targets, as well as creating a waste management model that can be applied in various regions in Indonesia and the world.

Abstract

Kelurahan Waena, yang terletak di Distrik Heram, Kota Jayapura, berada di kawasan pinggiran kota dekat Danau Sentani dengan tingkat sosial yang lebih rendah dibandingkan kawasan perkotaan yang maju. Sebagai kawasan hunian, Kelurahan Waena dirancang untuk melindungi dan memperkuat kearifan lokal masyarakat adat suku Tabi Papua. Kehidupan sosialnya memadukan sistem tradisional dan modern, di mana masyarakat tetap mempertahankan kelembagaan adat sekaligus mengadopsi teknologi modern seperti listrik dan peralatan elektronik. Untuk mendukung pemanfaatan listrik yang aman dan efisien, Lembaga Penelitian dan Pengabdian Kepada Masyarakat (LP2M) Universitas Cenderawasih (UNCEN) mengadakan kegiatan pemberdayaan masyarakat. Program ini bertujuan meningkatkan kemampuan masyarakat dalam mengelola energi rumah tangga secara tepat, efisien, dan nyaman. Berdasarkan tanggapan peserta, kegiatan ini berhasil mencapai tujuan dan memberikan manfaat nyata bagi masyarakat. Waena Subdistrict, located in Heram District, Jayapura City, is a suburban area near Lake Sentani with a lower social level compared to more developed urban areas. As a residential area, Waena is designed to protect and strengthen the local wisdom of the indigenous Tabi Papuan community. Its social life blends traditional and modern systems, where the community maintains customary institutions while adopting modern technologies like electricity and electronic devices. To support the safe and efficient use of electricity, the Institute for Research and Community Service (LP2M) at Cenderawasih University (UNCEN) organized a community empowerment program. This program aims to enhance the community's ability to manage household energy accurately, efficiently, and comfortably. Based on participant feedback, the program successfully achieved its goals and provided tangible benefits to the community.
