Uji Berbagai Diameter Puli Pada Alat Pembuat Sari Kedelai (Glycine Max)

Abstract

MUHAMMAD YUSUF: Pulley diameter test of soybean extractor, supervised by SAIPUL BAHRI DAULAY and LUKMAN ADLIN HARAHAP. There have been many soybean extractor in the market, that have been developed by home industry or university student. One of the soybean extractor was made by Winanda Pardhanu in Agriculture Engineering Program Study, University of North Sumatera. The capacity of soy bean extractor can be improved by testing their parts. This research was about testing pulley diameter of soybean extractor to improve its capacity. This research had been conducted at Agricultural Engineering Laboratory, Agricultural Faculty USU on June – August 2015 using factorial randomized block design with pulley diameters of 3, 4 and 5 inches. The observed parameter in this research was effective capacity of equipment, yield and percentage of materials left in appliance. The results showed that pulley diameter had highly significant effect on parcentage of process capacity and yield and had no effect on percentage of materials left in appliance. From this research it, can be concluded that the best pulley diameters was 3 inches.
