RANCANG BANGUN ALAT PENGIRIS KENTANG SCREW MEKANIS
ABSTRACT: To serve the need of
potato consumers for the ready good potato, it must be processed through
post-harvest . Some of the process is cutting and slicing. The need of
post-harvest processing that leads to mechanization and to get the optimum gain
and high efficiency, potato screw slicer had to be designed and constructed.
The study was conducted with literature study, experiment, observation and testing
of the equipment. The effective capacity of the equipment was 51,72 kg/h. Basic
cost to be incurred in slicing potato with the equipment was Rp. 199,72/kg in
the 1st year, Rp. 199,99/kg in the 2nd year,Rp. 200,26/kg in the
3rd, Rp. 200,56/kg in the 4th and Rp. 200,87/kg in the 5th. The equipment will
reach the break even point if the amount of slicing potato was 889,,30 kg/year.
Net present value of the equipment with an interest rate of7,5% was Rp. 391.040.422,54which
meant that the business was feasible to run. The internal rate of return was
49,45%.
