PERANCANGAN TURBIN ANGIN SUMBU HORIZONTAL 1500 WATT DI PANTAI WISATA SUWUK KABUPATEN KEBUMEN

Indonesia energy needs will continue to grow along the economic growth and energy consumption itself. As main energy source, the fossil fuel has been causing a lot of environmental problem. To solve the environmental problem requires the development of renewable energy. Among the several renewable energy, the wind power generation has shown the greatest progress. Suwuk beach is located in wind energy potential site and chosen as design site of 1500 watt horizontal axis wind turbine. The wind speed data was obtained from the PLTH Bantul-Yogyakarta. It was recorded by anemometer at height of 50 m above ground over 2 year’s periods from June 2013-June 2015. The wind speed data was calculated by Weibull statistical method. The results shows that the mean wind speed Vm= 5.87 m/s, parameter k= 2.36, and wind speed parameter c= 6.63 m/s. The airfoil NACA 4412, NACA 23012, NREL S822, and NREL S833 was calculated by Blade Element Momentum Theory (BEM). The final result of wind turbine design uses NACA 4412 airfoil as blade, output power 1,55 kW, diameter of rotor D= 3,2 m, swept area of rotor A= 8.042 m2, and 15 m hub height
