Abstract

This study evaluates the aerodynamic performance of low-speed horizontal-axis wind turbines for application in Indonesia’s 3T frontier regions (Terdepan, Terluar, Tertinggal), where wind resources are limited and access to reliable electricity is scarce. The investigation focuses on turbine blades employing the SG6043 airfoil, selected for its high lift-to-drag ratio at low Reynolds numbers, making it well suited to low-wind environments. Blades were manufactured from carbon composite materials to enhance strength-to-weight performance and durability. Experimental testing was conducted at the PLTH facility in Pantai Baru, Yogyakarta, using two generator capacities (600 W and 1000 W) and three blade configurations, including a baseline blade for the 1000 W generator. The highest electrical output, 121 W, was achieved by the 600 W generator with Blade B at 581 rpm and 9.4 m/s wind speed. The lowest output, 1.2 W, was recorded for the 1000 W generator with Blade A at 346 rpm and 5.8 m/s wind speed. The results confirm the SG6043’s suitability for small-scale wind turbines in low-wind, resource-constrained settings, and highlight its potential for improving rural energy access.
