| dc.description.abstract | HANDYMAN MAKMUR WARUWU: Performance and Operating Costs Oil
Palm Fronds Chopper Machine Designed by Agricultural Mechanization Unit of
North Sumatra Province, supervised by LUKMAN ADLIN HARAHAP and
ACHWIL PUTRA MUNIR.
Chopping is one way of size reduction of solids into smaller pieces to
produce solids of a certain size. Chopping with a mechanical equipment has not
much been done due to lack of knowledge and limitation of existing equipments of
the farmers. In fact, if it can be done can increase farmers' income. The aim of the
research was to test the performance of oil palm fronds chopper machine
designed by Agricultural Mechanization Unit in North Sumatra Province using oil
palm fronds as a raw material and analyze its operating costs. Observed
parameters were effective capacity, yield of chopping, the percentage of materials
left behind, and fuel consumption of the equipment.
The results showed that the effective capacity of the equipment was
287,29 Kg/hour. Chopping yield was 94,2%. The percentage of materials left
behind was 5,2%. Fuel consumption was 0,44 L/hour. Cost of Analysis was Rp.
53,9/Kg for the first year, Rp. 54,29/Kg for the second year, Rp. 54,48/Kg for the
third year, Rp.54,79/Kg for the fourth year, and Rp. 55,12/Kg for the fifth year.
BEP was 62.209 Kg in the first year, 65.862 Kg in the second year, 67.759 Kg in
the third year, 70.755 Kg in the fourth year and 73.947 Kg in the fifth year. The
IRR was 39,17%. | en_US |
