Uji Berbagai Diameter Puli Pada Alat Pencetak Terasi

Abstract

UNTUNG UTOYO : Test Different Diameter Pulleys on the Shrimp Paste Molder, supervised by SAIPUL BAHRI DAULAY and AINUN ROHANAH. Shrimp paste molder that had been designed previously was not effective in process, so the author suspect that the performance of the machine will be better if pulley with right diameters is used. The research’s purpose is to examine the effect of various pulley diameter on the effective capacity, yield, and the percentage of left material of the shrimp paste molder. This research was conducted in November 2015 to January 2016 in the Laboratory of Agricultural Engineering, Faculty of Agriculture, University of North Sumatra, Medan. The parameters observed were effective capacity, yield and the percentage of left material on the shrimp paste molder. The result shows that the highest effective capacity was 106,41 kg/hour at treatment D1 with 2 inch pulley diameter, the highest yield was treatment D1with 2 inch pulley diameter (66,6%), and the percentage of material left behind was the lowest at treatment of D1 with 2 inch pulley diameter (33,4%). From Duncan Multiple Range Tests it was found that the pulley diameter had highly significant effect on the effective capacity and had significant effect on yield and percentage of material left behind.
