Abstract

The purpose of this research is to design a micro-hydro power plant in Girimulyo Village, Ngargoyoso District as an alternative solution to replace the need for fossil fuels, the team tries to take advantage of field observations and calculations using the GPS (Global Positioning System) application with a water discharge Q = 0.2 m3/s. and waterfall height H = 16.5 m. Based on the existing water level and flow, the turbine used is the Pelton turbine. From the calculation of the effective head of 15.81 m. With the discharge of water used to rotate the Pelton turbine, a test was carried out and a power of 20,162 kW was obtained. From this power, it can be calculated that the shaft diameter is 38 mm. To facilitate the setting of rotation between the generator and the Pelton turbine rotation, a flat belt type transmission belt is used with a width of 300 mm and a thickness of 9 mm while the maximum tension of the belt is 39 kg with a tangent angle between the pulley and the belt of 7.180. Keywords: Micro Hydro, Power Plant, Pelton Turbine
