To produce quality rice, improvement in rice production management must begin at the farmer level (on-farm) by using high-quality seeds and good plant maintenance. Good quality rice is rice grains that don't break or crumble. To urge good quality rice, rice producers usually sort it manually. This method leads to long work processes and low productivity. Efforts to beat this problem are by designing a rice sorting machine which will separate whole rice and broken rice so on lighten the workload, improve rice quality, and increase prices. The results of the study obtained that the look specifications of the rice sieving machine were a). The sieving capacity is 10 kg of rice, the most drive is an electrical motor of 0.25 HP, a V-belt transmission, and an angled iron frame. Machine dimensions: length 120 cm, width 70 cm and height 90 cm). Machine testing the standard of rice grains employing a sorting machine can improve the standard of rice grains by reducing the presence of broken rice (size p=0.30 mm and below) a mean of 0.2 kg for 10 kg of sorted rice or increasing the standard by 1.91%. Machine testing from the ergonomic aspect.
