Performance Test of Shallot Dehuller Machine (Type BEJE PB 01) Bogor Agricultural Development Polytechnic Abstract Shallot is widely used in daily life. Its demand tends to increase even though Indonesia is still facing global pandemic due to Covid-19 outbreak. Before processing, its outer layer should be removed. However, it is time and energy consuming. Therefore, a shallot dehuller machine with theoretical capacity of 20 kg/hour was manufactured to increase peeling capacity. Various tests were conducted to examine the machine performance. The objectives of the research were to conduct performance test by identifying and evaluating mechanical aspects and providing recommendations after the tests concluded. An explanatory descriptive analysis had been chosen to observe, measure, and calculate the data. Results of performance test indicated that while the actual capacity was 14.52 kg/hour, its efficiency was 71.44%. The shelling yield was around 36.29%. During the test, the noisiness also measured which was about 88.4 dB. Moreover, motor and engine vibration were also measured. The results were 6.48 and 6 Hz of motor and engine vibration (without load). Furthermore, motor and engine vibration with load were about 5.96 and 5.56 Hz, respectively. Machine performance was relatively moderate. On the contrary, due to low shelling yield, further modification is needed to achieve better results.
