Many alternative energies from nature can be used to generate electricity, one of which is wind. Wind energy is energy that has great potential to be developed because wind energy is clean energy and in its production process does not pollute the environment. The wind turbine is a device used to convert wind energy into electrical energy. In this research, the wind turbine is used in Horizontal Axis Wind Turbine (HAWT). This study aims to design the right HAWT with existing potential data in Batu, Indonesia. Then the design of wind turbine components such as hubs (connecting the shaft with the blades), airfoil blades, guide tails, and tower poles. The research method begins with determining the initial specifications of the turbine, determining the airfoil profile, designing the blade geometry, and designing the turbine components. The potential wind speed data in Batu, Indonesia is 4m/s. We use the NACA 4412 airfoil with 3 blades of a propeller, and it is planned to produce an output power of 100-130 Watts. The generator used is a permanent magnet generator with specifications DC12-18V, 15A, 500-1000rpm, power: 270 Watt (max), dimensions: 10.5cm x 8.5cm, shaft diameter: 12mm. The length of the turbine blade is 0.5 meters with a pile height of about 4 meters above ground level. The material uses fiber because it is superior in terms of price and is resistant to all weather.
