The Savonius turbine is a wind turbine that has a vertical shaft parallel to the turbine blade and has advantages that can save wind energy from all directions at low speeds. The purpose of this study is to examine the Savonius turbine model with variation in the ratio of the blade inlet side and the blade outlet side to improve turbine performance. The research method used is turbine research; conduct an experimental test by varying the ratio of the inlet and outlet sides of the blade (1:1 and 1:2) to the speed of the blade’s wind flow. Then conduct turbine performance analysis to get the best efficiency between the ratio of the inlet and outlet sides of the blade. The test was carried out at wind speeds of 5 m/s, 7 m/s, 9 m/s, 10 m/s, and 12 m/s with lamp loads distributed between 5-40 Watts. Analysis of turbine performance test The test results show that Savonius single blade wind turbine has the best efficiency of 8.43% at 5 m/s wind speed and is able to produce electricity of 10 Watts and then the best efficiency released by a 1:2 double blade wind turbine that has efficiency by 6, 9% at a load of 20 Watt and a 1:1 double blade wind turbine which has an efficiency 4.37% at a load 10 Watt.
