Abstract

Desa Berahan Kulon Kec. Wedung Kab. Demak merupakan desa daerah pesisir pantai utara Jawa yang memiliki potensi perikanan yang cukup besar. Kegiatan usaha itu meliputi usaha perikanan air laut, air payau dan air tawar. Hasil tangkapan ikan laut setiap tahunnya tidak kurang dari 600 ton, serta budidaya ikan air tawar mencapai 97.6 ton per tahun. Potensi produksi ikan tersebut menyisakan limbah ikan dan kerang yang belum termanfaatkan dengan baik. Kegiatan yang dikeloala kelompok petani tambak dan nelayan tersebut juga memiliki masalah pada suplai dan harga pakan ikan yang selalu berubah-ubah. Akibat permasalahan tersebut usaha tambak yang dikelola melalui Kelompok Budidaya Ikan Margo mulyo mengalami kerugian. Adanya potensi dan permasalahan tersebut maka dilakukan kegiatan pengabdian masyarakat terkait kemandirian pakan ikan dengan penerapan teknologi mesin pembuat tepung ikan. Penerapan teknologi pencacah multi blade untuk memudahkan proses pengolahan limbah ikan tangkapan nelayan menjadi tepung ikan. Kegiatan kemitraan ini difokuskan bagaimana menyediakan alat produksi tepung ikan dan pelatihan produksi bagi nelayan. Kegiatan kemitraan UMKM Margo Mulyo Abadi dengan UNS ini mampu menjadi solusi akan isu yang berkembang, sekaligus mampu meningkatkan nilai ekonomis limbah ikan sehingga terdapat peningkatan pendapatan bagi para anggotanya. Kata kunci: Pemberdayaan; Teknologi Pencacah; multi-blade; limbah ikan; tepung ikan.

Abstract

The use of fossil fuels in the form of petroleum, coal and natural gas in the long term as conventional power plants causes the scarcity of these fuels in the future. Then the use of new renewable energy such as wind and solar energy must be optimized. In Indonesia, both of these energies have the potential to be environmentally friendly power plants. Experimental research conducted on the coast of Demak Regency aims to determine the potential of wind and solar energy there and the use of both energy as pond lighting. The concept of a combination of solar panels and savonius turbines can produce complementary energy. During the day the battery charging is obtained from a combination of solar panels and savonius turbines while at night the Savonius turbine will still produce electricity. The S-type savonius turbine made from galvalum is mounted on a 6 m tall tower while the 100 WP solar panel is mounted beside it with a 90 slope. This penelitian use expermental methods. Data collection of wind speed, light intensity, electric current, and electric voltage is carried out periodically 20 minutes at 06.20 s.d. 17.20 Western Indonesian Time. Electrical power is obtained by multiplying curr Data analysis in this study uses quantitative descriptive analysisent and voltage. The combination produces enough electricity for lighting a pond in the village of Berahan Kulon, Kecamatan Wedung. The power generated from a combination of hybrid plants can reach 46,2 watts with the intensity of sunlight of 125000 luxmeter and constant wind speed around 2 to 4 m / s. From these results, a combination of turbine savonius and solar panels is more optimal compared to a stand-alone savonius turbine.

Abstract

The availability of fossil fuels in Indonesia has recently been running low due to exaggerated use of the fuel. To fulfill the electrical energy needs of the community which more environmentally friendly used, wind turbines can be used. In this study, researchers use a micro-scale horizontal axis wind turbine from wood and composite materials on the blades, where it try to determine the effect of each performance. This study uses an experimental method which is carried out at the Wind Tunnel Laboratory of the Mechanical Engineering Education, Sebelas Maret University. The variables are blades with a variety of composite and wood material. Performance of electrical power is investigated in this research. Data shows that the wind speed 5m/s - 6m/s composite without load produces the highest rotate, which is 544.64 rpm. While, wood material take lower at 494.2 rpm. The wind turbine is driven at 5 m/s – 6 m/s by using 12V of load. It produces 367.68 rpm and 6.771 watts for composites, and 303.6 rpm and 5.047 watts for wood. So it can be concluded blade materials could effect to the turbine performance.
