The horizontal axis taper blade with a NACA 4415 airfoil made from Pinus Merkusii as softwood and Swietenia Macrophylla as hardwood has been designed and tested to determine its resistance as a micro-scale wind turbine blade material based on the rotor speed. Softwood and hardwood blades were analyzed by static simulation based on the values of von Mises stress, displacement, and Factor of Safety. The simulation results show that softwood and hardwood blades have good resistance and safety to be used as micro-scale wind turbine blade materials with rotor speeds of 200, 300, and 400 rpm, with Factor of Safety values above 1.0 for both types of wood at all variations of rotor speed. Factor of Safety values for softwood blades are 4.9, 2.3, and 1.3, while hardwood blades are 9.6, 4.5, and 2.5.
