Abstract

Abstract: South Java Coast in Indonesia is a potential location for developing wind power due to the abundant wind resources. One of the prospective areas is Baru beach, Srandakan, Bantul, Yogyakarta. In this area, the wind speed could reach 0-12 m/s with the average speed was 6 m/s. The objective of this research is to design and manufacture of Hawk Wings blades. The blades were hardly stop when spinning resulting quick rotation and high torque which were suitable for the wind characteristics at Baru beach. The windmill installation consists of some main components, i.e. blade, AC generator 3 phases, tower and foundation, wind orientation control, rectifier, battery, and load. The direct method using 2000 watt generator was used to design the wind mill. The blade was disassembled and then installed to the generator axis. The DC electricity was used as a power for charging 12 volt batteries. At Baru beach, the blade with a radius of 95 cm, width 24 cm base, 8 cm wide end a angle of 0-37° produced rotation of 0-2000 rpm, and voltage of 0-48 volts. The tests were carried out for 38 hours resulted in 3224, 86 watt hour energy. As a result, the average of 1 hour production process generated electrical energy in the form of DC at 84.86 watt-hour.
