UJI RPM PADA ALAT PARUTAN KELAPA KERING (DESICCATED COCONUT)
ABSTRACT: This research was
done to test the effect of rpm on the effective capacity of the equipment,
percentage of material left in the equipment, and yield. This research was
using non factorial completely randomized design. It was found that the work capacity
of the equipment, percentage of material left in the equipment, and yield on
1125 rpm are 83,128, 12,17%, and 87,83% kg/hr respectively. On 900 rpm are
75.650, 19,33%, and 80,33% kg/hr respectively. On 750 rpm are 70,484, 25%, and
75% kg/hr respectively. The results showed that number of knife edge had
significant effect on percentage of material left in the equipment, and yield
and had significant different on the work capacity. The main cost from year one
to year seven were Rp. 143,52, Rp. 134,90, Rp. 132,04, Rp. 130,61, Rp. 129,76,
Rp. 129,31, and Rp. 128,78 per kg respectively. Break even point from year one
to year seven were 1552,55, 835,26, 596,50, 477,32, 405,96, 368,42, 324,75 kg
respectively. The result of net present value from 6% of bank rate was Rp.
1.518.446.869,44 which means this business was competent. The internal rate of
return was 35,6% which means this business was competent if the bank rate were
not more than 35,6%.
