| dc.description.abstract | MUHAMMAD ARIEF GILANG PRATAMA: Pulley Diameter Test of Organic
Waste Grater, supervised by SAIPUL BAHRI DAULAY and AINUN ROHANAH.
Organic waste grater begins popular in society, either used for compost
making or livestock feed. The machine was invented based on society concern for
environmental issue. One of the grater was designed by Doni Apriano Purba in
Agricultural Engineering Study Program, University of North Sumatra. It can be
improved by testing some part of it. This research was about testing some
variation of pulley diameter on organic waste grater to improve its capacity. This
research had been conducted at Agricultural Engineering Laboratory
Agricultural Faculty University of North Sumatra on March- April 2016 using
factorial randomized block design withpulley diameters of 7, 8, and 9 inches.The
observed parameters in this research were yield, percentage of materials left in
appliance, and effective capacity of equipment.The results showed that pulley
diameter had highly significant effect on percentage of process capacity, and had
no effecton yield and percentage of materials left in appliance.From this research,
it can be concluded that the best pulley diameters was 9 inches. | en_US |
