Pengaruh Variasi Mata Pisau dan Tingkat Kadar Air Bahan terhadap Kinerja Alat Penggiling Jagung

Abstract

Corn is one of the agricultural commodities that is widely cultivated. Corn that has been harvested will be processed in the post-harvest stage. One of the tools used for corn during post-harvest is a corn grinder which is used to make corn into flour or ground corn. In order to optimise the tool's use in terms of its effective capacity, yield, and percentage of material wasted, this research was done to determine the ideal number of blades and degree of material moisture content in the corn grinder. The Factorial Completely Randomised Design (CRD) method with two factors—the blade's variation and the material's water content—was employed in this study. There are three different numbers of blades in the tool: four, five, and six. The moisture content of the maize ingredients is also different: 12%, 14%, and 10%. The results of the research show that the effective capacity of the tool, the yield and missing materials do not interact so each parameter is described separately. The best effective capacity of the tool is found on blade 5 and a water content of 10%, the best yield and percentage of material lost is found on blade 3 and a water content of 10%.
