Wind power is one of the fastest-growing renewable energy sources in the world because of its many advantages. Wind power also presents fundamental challenges in some regions of the world, which are being addressed through research and development projects. This study aims to design and analyze propeller wind turbine for low-speed regions especially in those frontier, outermost and least developed regions often referred to as 3T (terdepan, terluar, tertinggal) in Indonesia. An open-source numerical software tool for aerodynamic and structural analysis of wind turbines is used to design airfoils. Four different airfoil types are selected based on literature study which produced four turbine blades: S826 (Antasena 1.1), NACA 4412 (Antasena 1.2), NACA 4415 (Antasena 1.3), and SG6043 (Antasena 1.4). Through simulations and analysis, it is found that Antasena 1.4 (SG6043) is the most suitable airfoil for low wind speed conditions (3-5 m/s). The power output predictions for various wind speed classes indicate that Antasena 1.4 has the highest potential power output, meeting and even surpassing the target values in certain months. Numerical simulation of Antasena 1.4 shows best power coefficient (Cp) 0.5747. The results demonstrate the promising applicability of Antasena 1.4 as an airfoil profile for turbines operating under low wind speed conditions.
