STUDI RANCANGAN PEMBANGKIT LISTRIK TENAGA MIKROHIDRO (PLTMH) PADA ALIRAN SUNGAI CISADANE DI KELURAHAN KERANGGAN

Abstract

The need for electricity has increased every year. One of the most popular supply of electrical energy is electrical energy from energy sources flowing and plunging water, called as the Micro Hydro Power Plant (PLTMH). Cisadane River is one of the major rivers with length around 80 kilometers and crosses 44 districts in 5 regencies / cities, including desa Kranggan, South Tangerang. Therefore, community service is carried out in an effort to utilize and optimize the flow of the Cisadane river. The Study of PLTMH design for community service program was conducted. Data of river flow, altitude and location of the river flow will be collected so that it can be calculated and observed for the design of PLTMH that best suits the efficiency of the largest electrical energy, which is obtained using the TurbinPro software program. PLTMH planning chose to use a propeller/kaplan turbine because of its low head which is 4 meters. The power generated is 994 kW at a maximum head with an efficiency of 91.2% and a river flow of 52.26 m3/s and at a minimum head of 601 kW with an efficiency of 82.2% and a discharge of 47.56 m3/s. Keywords: electrical energy, community service program, PLTMH, power generation, Kaplan turbine
