Effect Of Pressure On The Press Machine On The Percentage Oil Losses At The Pressing Station Of The PT. Sentosa Kalimantan Jaya Berau Palm Oil Mill

Abstract

Palm oil mills are required to produce crude palm oil (CPO) products as much as possible while still meeting the SNI quality requirements. Therefore, the effectiveness and efficiency of each stage of the process plays an important role. One of the problems that often arises is the high percentage of oil losses, especially in the pressing process. This study aims to determine the effect of variations in press machine pressure on the percentage of oil losses in mesocarp fibre dregs.
 The research was conducted on press machine no. 1 PT. Sentosa Kalimantan Jaya (SKJ) palm oil mill, Berau district, East Kalimantan. With pressure treatment at three levels, namely 50, 60, and 65 bar. The results obtained were analysed for oil content and then identified and analysed using a causal diagram.
 The results showed that the increasing pressure on the pressing machine was inversely proportional to the percentage of oil losses in the dregs, but the broken kernels also increased. The best pressure is at 65 bar with an oil loss percentage of 4.19%. Based on the results of the cause-and-effect diagram, there are 4 factors that can affect the high or low percentage of oil loss, including: raw material factors, human resource (HR) factors, machine factors, and environmental factors
