The research objective are to analyze and to compare the effect of the variation of the wind speed and the number of turbines blades to the electric power generated by wind turbine using NACA 2412, 4412, and 6412. The variation of the number turbine blades used 4, 5, and 6 unit and the variation wind speed is 3.0 till 6.0 meter per second. The research variables are variation of the wind speed and number of turbines blades as independent variables, and the electric power as dependent variable. This research applies quantitative method is experimental design using two way classification and data simulation. The finding of this research reveals is 1). The first null hypothesis is rejected, it means there is a difference effect between variation of wind speed to the electric generated power by wind turbine using NACA 2412, 4412, and 6412. 2) The second null hypothesis is rejected, it means there is a difference effect between variation of turbine blades to the electric generated power by wind turbine using NACA 2412, 4412, and 6412.
