Coffee is one of Indonesia’s leading agricultural commodities, yet post-harvest processing particularly the peeling of coffee husks remains largely manual and inefficient. This study aims to design and analyze a semi-automatic coffee husk peeler using a gear mechanism to improve productivity and reduce physical labor. The machine was tested using 10 kg of Arabica coffee beans with three gear ratio variations (1:2, 1:3, and 1:4). Parameters measured included peeling efficiency, time consumption, and energy use. Results show that the 1:3 gear ratio provided optimal performance with 92% peeling efficiency and reduced processing time by 35% compared to manual methods. The design demonstrates that mechanical gear systems can effectively enhance small-scale coffee processing, supporting appropriate technology for rural communities.
