Wind energy is one type of renewable energy which is not only clean andenvironmentally friendly but also has abundant and is obtained free of charge in the natural. The process of converting kinetic energy in the wind into mechanical energy requires a turbine. Darrieus turbine is a device that converts wind energy that moves from various directions into mechanical energy on a shaft that moves in one direction. This study aims to determine the performance of a two-blade Darrieus turbine with the NACA 0028 profile experimentally. The wind tunnel, Darreus turbine, and load-bearing construction were designed and manufactured by researchers. Data collection of wind velocity, load, and rotation using standard equipment. The results of the study show that the turbine power coefficients are 35.57%, 23.55%, 23.2%, and 20.05% at wind velocity of 6.04, 7.08, 7.25, and 7.59 m/s, respectively
