Modifikasi Rotor pada Alat Pemecah Buah dan Pemisah Biji Pala Mekanis

Abstract

To meet the export needs of nutmeg, the role of agricultural processing technology, especially in brealing stage is very important.this process has been done mechanically but it still produced higher losses compared to the perfect breaking. The purpose of this research was to modify the rotor and the power used to increase the efficiency of nutmeg breaking using a mechanical nutmeg breaker. In this study, the physical and mechanical properties of nutmeg were measured to modify the rotor and power used in the nutmeg breaker, and an economic analysis was conducted to analyze the economic feasibility of the tool. Furthermore, based on economic analysis, this tool is feasible to use as a result of NPV> 0, which is Rp. 1,254,544,308 / year at 6% interest rate and Rp. 1,167,556,065 / year at 10% interest rate. BEP value of 3. 927.273 Kg / year. And the IRR value on this tool is 67.69%. This research is focused on determining the dimensions of each component such as V-belt, rotor breaker, power from the design combustion motor using solidwork.
