One promising renewable energy source is wind energy. Wind energy is an abundant renewable energy source to produce clean energy. A wind turbine is a device used to convert wind energy into kinetic energy. The average wind speed is 3-7m/s in Indonesia, classified as low wind speed. Savonius wind turbines can produce high torque values at low wind speeds. Making curvature variations on the blades of savonius wind turbines is one form of development to improve the performance of these wind turbines. This study aims to determine the effect of blade curvature from 0% to 100% blade curvature variations and wind speed from 3m/s to 10m/s on the value of Coefficient of Power, Torque, and Rotation Speed. The method used is Numerical using CFD (Computational Fluid Dynamic) software Solidworks. As a result, the largest Coefficient of Power value was in the 10% blade curvature variation, which was 52.0224% at a wind speed of 5.5m/s. The greatest torque value is in the 20% blade curvature variation, which is 0.1399 Nm at a wind speed of 10m/s. Then, the greatest rotation speed value is in the 10% blade curvature variation, which is 713.3005 Rpm at a wind speed of 10m/s. Keywords: Savonius turbine, Coefficient of Power, Torque and Rotation Speed.
