In the era of global energy uncertainty and the negative impact of fossil fuels on the environment, Indonesia, as a developing country with rapid economic growth, faces serious challenges related to the significant increase in energy consumption. To address this, exploring renewable energy sources such as wind energy is crucial. This study aims to design and analyze a wind turbine using the NACA 4412 airfoil through Computational Fluid Dynamics (CFD) methods. The objectives include determining the optimum Tip Speed Ratio (TSR), identifying the appropriate turbulence model in CFD simulations, and comparing the performance of wind turbine blades with and without twist. Simulation results indicate that the K-epsilon RNG turbulence model produces the highest power coefficient (Cp) of 44.93% at TSR 7, while the K-omega SST model achieves a maximum Cp of 34.95% at TSR 6. Blades with twist show higher efficiency, achieving the highest Cp of 34.95%, compared to non-twist blades with a Cp of 28.58%. The optimal angle of attack (AoA) of 5.35° yields the highest power coefficient. The final wind turbine design features a diameter of 1 m, NACA 4412 airfoil profile, and 3 blades. This research emphasizes the utilization of wind energy to support the sustainability of renewable energy
