Abstract

The quality and quantity of rice is very much determined by the post-harvest process. Utilization of agricultural machinery in the form rice milling unit is one solution in maintaining rice quality. The most commonly used husker machine is a rubber roll type. This study aims to calculate the efficiency of huskers and the quality of rice. The parameters measured to analyze the efficiency of the milling machine and the quality of rice are the weight of unhulled rice to be milled, the weight of milled rice, and the time for milling the grain to become rice. The results showed that the husker efficiency at 1237 rpm rotation speed was 46.3%, at 1354 rpm was 46.7% and at 1395 rpm was 46.6%. The quality of rice produced at a rotation speed of 1237 rpm, 70.03% whole grains, 3.58% broken grains, 1.51% groats. For 1354 rpm rotation speed is 67.75%, broken grains 5.16% and groats 2.89%. While at the rotation speed of 1395 rpm the percentage of broken grains was 56.26%, broken grains 4.80%, groats 1.27%.
