This study aims to improve the performance of HAWT's wind turbines in low wind speeds condition. There are two possible approaches: developing low-speed rotor technology and improving the turbine's blades. In this research, we improve the turbine's blades by determining the type of airfoil, material and pitch angle. The airfoil used as its blade is NACA 4412 with teak wood material. Variations of pitch angles are at 0 ° 2 ° 4 ° 6 ° 8 ° 10 ° and 12 °. Testing is realized by making an artificial wind in the wind tunnel. The imitation speed are of 2 m/s, 2.5 m/s, 3 m/s, 3.5 m/s, 4 m/s, 4.5 m/s and 5 m/s. The result shows that at 4° is the best pitch angle that produces the maximum power output and rpm. The 4° pitch angle has a cut in of 2m/s wind speed and generates a power output of 9.71 Watt at an average Rpm of 505.6. The increasing pitch angle decreases the power output and RPM generator.
