Abstract

Rice husk is a waste from rice milling that can be utilized by most people, because rice husk contains nutrients and protein. Therefore, this rice husk has many uses, one of which is used as animal feed. To make it animal feed, it requires processing in a puree way so that it is easily digested by the livestock. Seeing this problem, it is necessary to make a rice husk smoothing machine. The working principle of the rice husk smoothing machine is carried out by inserting the rice husk into the inlet funnel which will be refined by the blade, then utilizing the gasoline motor as the prime mover, where the rotation of the machine is continued by a main shaft circuit consisting of 10 blades, the shaft with a diameter of 19 mm, a bearing size of 2.5 inches, V-belt type A 41, and a pulley diameter of 10 cm, as the main components of the rice husk smoothing machine. The capacity of the rice husk smoothing machine is 2400 kg within 8 hours/day of machine operation. The results of grinding the husks within 2 minutes of testing can grind an average of 0.90 kg of fine husks with a rotation of 4815 rpm. So in a day the rice husk smoothing machine can refine 2400 kg in 8 hours or a day of machine operation.
