【 摘 要 】

Dome of the mosque tower with an altitude of over 40 meters above the ground surface is getting strong winds, and it is commonly and widely applied to the mosque in Indonesia. The wind can be used to rotate the dome of the mosque tower as turbine ventilator. This paper develops a turbine ventilator model for mosque tower's domes that eventually can generate electricity. Dome tower constructed as turbine model, by the size of a ventilator, 1250 mm and a stator shaft shaped solid and hollow. These two shafts are connected to the bearing, while turbine blades are connected to the hollow. The speed of the turbine ventilator model of the mosque tower's domes is caused by the wind that rotates the turbine blade. The test is done by using a wind tunnel equipped with an axial fan at its end. When the turbine rotates, the hollow which is paired with a gear at its end has a ratio of 4:1, and is accelerated the rotation of the DC generator shaft. At a wind speed of 3m/s, it produces a turbine rotation of 720 rpm, and the generator shaft rotation is 2880 rpm. The output current is 98 A. When the wind speed is increased to 5m/s, the turbine rotation increases to 1300 rpm, the rotation on the DC generator shaft increases to 5200 rpm. The output voltage and current are 42 Volt and 130 A, respectively. Both the output voltage and current are adequately generating electricity for several lightings in the mosque.
