UJI KINERJA MESIN PENCACAH DENGAN VARIASI VBELT JENIS CLASSICAL DAN COGGED
The chopping machine has various components. Once of the importance components is the power supply component. It covers on v-belt, bearing, and pulley. The v-belt on the agricultural chopping machine is one of the connecting belt is used to transmit the power from one shaft to other shafts through a pulley that rotates with similar or different speeds. the aims of this study were to know the effectiveness of classical and cogged type v-belt in transmitting the power from the driving motor to the cutting blades of the chopping machine on the agricultural waste, and to know the performance of chopping machine on the agricultural waste in chopping guinena grass (panicum maximum). This study was conducted from November 2020 to March 2021. The data collection and tool modification took plasce at the laboratory of agricultur faculty, University of Borneo Tarakan. The research method used in this study was identyfing the problem, determining the type of v-belt, and testing the performance of the chopping machine on the agricultural waste. The data were analyzed based on 5 parametes (electromotor speed, Motor temperature, effective tool capacity, yield, and linier speed). The results of the study showed that the best performance of chopping machine was cogged v-belt A-53 with the average value of electromotor speed was 242,4 rpm, tha average value of temperature was 61 C, the effective tool capacity was 12,55 kg/hour, the yield was 92,9 %, and finnaly the linear speed was 5,07 m/s. by using well so its performance became maximally worked.
