PENGARUH BERAT BAHAN DAN TEKANAN TERHADAP PEROLEHAN MINYAK KEMIRI DARI BIJI KEMIRI DENGAN PENEKANAN MEKANIS (HYDRAULIC PRESS) (Effects of Weight and Pressure on Yield of Candlenut Oil from The Nut Candlenut with Mechanical Pressing (Hydraulic Press

Abstract

Candlenut oil obtained from processing candlenut seeds (Aleurites moluccana). By seeing a high oil content in the candlenut seeds which is equal to 50-60% the potential to be exploited. Hazelnut oil extraction process can be done in two ways, among others, the pressing (pressing) and dissolution (solvent). Two common ways namely mechanical presses include hydraulic presses (hydraulic pressing) and screw pressing. In this research study on the influence of material weight and pressure pressing against the acquisition of candlenut oil with hydraulic pressing method. Candlenut seed with good quality dried in an oven with a temperature of ± 80°C for ± 6 hours, after dried and then pressed using a hydraulic press. From the results of research on the weight of the variables obtained the largest yield in weight of 400 grams with a yield of 41.05% and the variable pressure the yield obtained at a pressure of 130 kg/cm2 with a yield of 41.57%. Analysis of organoleptic tests, the acid number and saponification numbers, it can be concluded that the candlenut oil produced to meet the standard.
