Test of Variant of Knife Edge Shape on Mechanical Coconut Peeler

This research was done to test the varian t of the knife edge shape on the effective capacity of the equipment, percentage of material unpeeled, and fuel consumption on mechanical coconut peeler. This research was using non factorial completely randomized design. It was found that the effective capacity of the equipment, percentage of material unpeeled, and fuel consumption were 231.24 unit hour -1 , 6,67%, and 2.37 litre hour -1 respectively triangle knife edge,  301.97 unit/hour, 13.33%, and 2.62 litre/hour respectively cone knife edge, and 192.48 unit hour -1 , 13.33% and 1.85 litre hour -1 respectively nail knife edge. The results showed that the varian t of knife edge had significant effect on the effective capacity and fuel consumption and had no effect on the percentage of material unpeeled .
