The current renewable alternative energy has begun to be widely developed in Indonesia is wind energy which is used to drive turbines to meet human needs for electrical energy. The energy possessed by the wind can be utilized and used in the form of wind kinetic energy which is then converted into rotation of the shaft on the windmill which is then converted through a generator into electrical energy. This study focuses on the design of a vertical type Savonius wind turbine (VAWT) by analyzing the effect of variations in the number of blades, wind speed and overlap ratio on turbine performance. The turbine design variations used are the number of blades as much as 3,4 and 5 blades with variations in the overlap ratio of 0.15; 0.30 and 0.45 for wind velocity 5 m/s. The method used in this study is a simulation with the numerical simulation method which is then optimized by the RSM (Response Surface Methodology) method. The test results show that the optimum wind speed is 2 m/s with a design of 3 blades at an overlap ratio of 0.30 with an efficiency value of 29.55%. © 2023 American Institute of Physics Inc..
