The pitch angle on the Darrieus turbine affects the performance of the turbine. The pitch angle always changes according to the shape of the blade profile and fluid velocity. This study aims to find the magnitude of the pitch angle on the NACA 0018 profile blade and its change of the blade edge statically. Model formation, element division, and analysis of blade characteristics are simulated by CFD. The results show that the pitch angle in the blade that did not change the trailing edge shape was -12.5o and in the blade that experienced changes in trailing edge shape by -13o.
