Performance and Economic Evaluation of Rice Combine Harvester in the Innovation Village of Subang, West Java, Indonesia

Abstract Traditional rice harvesting in Indonesia involves manual techniques with significant grain loss. This study assesses the performance and economic viability of a rice harvester, comparing it to manual methods in Subang Innovation Village. The research examines various parameters, including performance indicators (effective field capacity, theoretical field capacity, field efficiency, and harvesting losses) and economic indicators (harvesting costs). Results show that manual cutting yields an average effective field capacity of 0.021 ha/hour/person and a field efficiency of 82.5%, while combine harvester-assisted cutting achieves 0.504 ha/hour with a field efficiency of 82.2%. Combine harvesters significantly reduce losses to 0.07%, and the associated cost drops from 3,531,577 Rp/ha for manual harvesting to 1,857,143 Rp/ha with combine harvesters.
