RANCANG BANGUN PEMBANGKIT LISTRIK TENAGA MIKROHIDRO DENGAN PEMANFAATAN ALIRAN ANAK SUNGAI MENGGUNAKAN CONTINUOSLY VARIABLE TRANSMISSION

ndonesia has set ambitious targets to increase the share of renewable energy in its energy mix, with Micro-Hydro Power Plants (PLTMH) being one of the renewable energysolutions. This study focuses on developing a PLTMH utilizing the flow of the Tukad Sungitributary in Banjar Ganter, Desa Abian Tuwung, employing a Continuously Variable Transmission(CVT) as the transmission mechanism between the turbine and generator. A water flow rate of0.44 m³/s was capable of generating up to 8.580 kW, while a flow rate of 0.026 m³/s was used toproduce a hydraulic power of 484.12 watts and a generator output of 313.227 watts. Testingrevealed a decrease in turbine speed from 527.88 rpm to 315.8 rpm (40%), while the generatorspeed increased from 315.8 rpm to 1509.8 rpm (378%). Although the CVT improved generatorspeed, the system efficiency decreased due to the inability of the CVT to stabilize rotations andthe occurrence of v-belt slippage caused by water splashes. The reduction in turbine speed andinsufficient torque indicated that the CVT's performance was not significantly different from thatof conventional pulley systems.
