Uji Variasi Putaran Pulley terhadap Hasil Alat Perontok Kacang Tanah (Arachis hypogaea L.)

Abstract

Peanuts (Arachis hypogaea L.) are the second most important legume crop after soybeans and belong to the Fabaceae family. Nuts, including peanuts, have an important role in our food needs. Peanuts also have great economic value, so many people use them both as food and as industrial products. The aim of this research was to test variations in pulley rotation on the results of a peanut thresher. Research calculation parameters on tool performance are effective tool capacity, electrical power consumption, yield and percentage of material that does not fall out. This research uses 3 pulley variations, namely 3 inches with a rotation of 1400 rpm, 6 inches with 700 rpm and 9 inches with 467 rpm. The research results showed that the average effective capacity of the tool on a 3 inch pulley was 70.24 kg/hour, 6 inches 61.43 kg/hour, 9 inches 60.54 kg/hour. Electrical power consumption on the 3 inch pulley is 821.7 watts, 6 inches 626.26 watts, 9 inches 580.8 watts. The yield on a 3 inch pulley is 10.4%, 6 inches 9.65%, 9 inches 8.51%. The percentage of material that does not fall out on a 3 inch pulley is 15.55%, 6 inches 26.71%, 9 inches 29.32%. Using a 3 inch pulley results in the quality of the pods breaking apart because the rotation is too high during the threshing process.
