DESAIN PEMBANGKIT LISTRIK TENAGA MIKRO HIDRO MENGGUNAKAN KINCIR AIR TIPE OVERSHOT DENGAN BENTUK SUDU MANGKOK DAN BENTUK SUDU DATAR

Lack of electrical energy in Indonesia is still a problem for the Government of Indonesia. Areas that do not have the potential of fossil fuel resources tend not to have electricity from PLN. Utilization of water energy as a power plant becomes one of the solutions that can be applied. The potential energy of water (waterfall) and kinetic energy of water (river flow) is utilized by using a waterwheel to generate electrical energy. In the PLTMH prototype, the independent variables used in the form of blades and valve openings. While the fixed variable used is the number of blades, parallel pump circuit, overshot nozzle shot and 1 hour operation time. Based on the results of the research note that valve openings affect the discharge, the number of rotation, the mechanical power of the mill and generator power. The larger the valve opening, the greater the discharge of water that hit the turbine, the greater the turbine rotation and the greater the mechanical power of the mill and generator power generated. The design, discharge, number of rotation, the highest mechanical power of the mill and generator power is generated by a flat blade flange with a discharge of 36 liters / minute, a turning of 477.05 rpm, mechanical power of 190.71 Watt mill and 156.56 Watt generator power. Actual, the discharge, the number of rotation, the mechanical power of the mill and the highest generator power is generated by a flat blade flange with a discharge of 32.3 liters / minute, the number of rounds of 319 rpm, the mechanical power of the wheel 109,71 Watt and the generator power of 105 Watt
