Rancang Bangun Alat Pemarut dan Pemeras Kelapa sebagai Bahan Pembuatan VCO (Virgin Coconut Oil)

Abstract

Coconut grater and squeezer tools as ingredients for made VCO were grater and squeezer that can complete two processes in one tool. The purpose of this research was to produce a prototype of a grater and squeezer tool coconut and to test the performance of the tools built. From the results of tool design, produced a grater and squeezer with dimensions of 52 cm × 32 cm × 100 cm used an electric motor 1 hp shaft rotation 1400 rpm. Grate speed 1050 rpm and 46,67 rpm screw speed with a gearbox ratio 1:30. Results the research showed the effective capacity of the tool was 9,421 kg/hour and the production capacity 4,531 kg/hour. The yield of coconut milk was 40,5% and the yield of VCO was 6,42%. The result of the trial of coconut milk processed 0,483 kg and VCO of 0,032 kg. The basic cost obtained was 1582,428 IDR/kg, BEP of coconut milk was 115,802 kg/year and BEP of VCO was 0,841 kg/year.
