Abstract

This study aims to analyze the performance of a rice threshing machine with a 100 kg/hour capacity driven by a 6 HP gasoline engine on Ciherang rice variety. The main parameters observed were working capacity, threshing efficiency, yield loss, and fuel consumption. The experiment was conducted under five rotational speeds (600–1400 rpm). The results showed that the highest efficiency of 88% was achieved at 1200 rpm, with the lowest yield loss of 12%. At higher speeds, efficiency decreased due to grain breakage and increased losses. The optimal operational point of this machine was achieved at 1200 rpm, where performance, fuel economy, and grain quality were balanced
