Abstract

Peanut shells are one of the major agricultural wastes generated from peanut processing in Indonesia and are still underutilized, despite their potential use as animal feed. This study aims to design, fabricate, and evaluate the performance of a peanut shell chopping machine with a design capacity of 15 kg/h. The machine was developed using the systematic engineering design approach proposed by Pahl and Beitz, supported by morphological analysis to select the optimal design concept. The chopping mechanism is driven by a 0.75 hp three-phase AC electric motor and employs a V-belt and pulley transmission system. Performance tests were conducted at a shaft speed of 1191 rpm using four chopping blades, with blade spacing variations of 20 mm, 10 mm, and 5 mm. The results show that blade spacing significantly affects chopping performance. The highest chopping capacity, reaching 21.46 kg/h with a target particle size of 3 mm, was obtained at a blade spacing of 20 mm. These results indicate that the proposed machine meets the design objectives and is suitable for small-scale applications to improve the utilization of peanut shell waste as animal feed.
