Uji Jarak Mata Pisau pada Mesin Pengiris Jahe (Zingiber officinale Rosc.)

Abstract

Ginger (Zingiber of ficinale Rosc .) is a multifunctional plant that is widely processed as a kitchen spice, raw material for making medicine and is often processed to make food and drinks. In the community, ginger slicing is still done manually, which makes the ginger slicing time take longer. With the ginger slicing machine, it is hoped that it will speed up and make ginger pr ocessing easier. The aim of this research is to test the blade with the parameters for calculating the effective capacity of the tool, yield, percentage of wasted material and economic analysis. The ginger slicer has 3 blade distances, namely: 1 mm, 3 mm a nd 5 mm. Based on the test results, the average effective capacity of the tool was obtained, namely: 41.32 kg/hour, 24.50 kg/hour and 17.96 kg/hour. The average yields from the test results are: 86.47%, 85.87% and 81.80%. The average wasted material from t he test results is: 8.4%, 8.1% and 11.7%. Economic analysis of ginger slicing found that the basic cost was IDR 1.05 /kg, the BEP (Break Even Point) was IDR 360,072 kg/year, the NPV (Net Present Value) was IDR 106,952,411.1/year and the IRR (Internal Rate) percentage of Return) 42.71% which states that the machine is very suitable for commercialization.
