| Summary: | The research conducted to analyze and optimization of Darrius wind turbine based on air velocity and twist angle blade which can influence of turbine torque, turbine rotation speed and turbine power capacity. The method of research uses three steps that is the air velocity observation, wind turbine design, and simulation of wind turbine design. The twist angle as a variable parameter has degree angle of 0° and 30°. The result showed that the Darrius wind turbine with the twist angle of 30° which has chosen has the torque value is 0.285 N m that capable to increase the rotation speed is 6.42 rpm, and generate the turbine power capacity is 0.221 W. The research will be continuing to data validation with the result of pilot scale experiment.
