Abstract

This research discusses the control of throughput in a palm oil mill (POM). The purpose is to find out how the POM throughput conditions and how the losses due to these conditions. This research uses the individual moving range (I-MR) Chart method. Testing is done first with MR-Chart, and revisions will be made if there is an out-of-control condition. Next, testing of throughput conditions with x-Chart will be conducted. If an out-of-control condition occurs, a process capability measurement (Cp) will be carried out. The result showed that the POM studied had poor throughput conditions. To make the existing conditions seem good or very good, tolerance is needed that is beyond the limit of reasonableness. This condition resulted in considerable losses for the company because it had to spend operational cost because there were additional operating hours that should not have happened, even though there were no FFB processed during these additional hours.

Abstract

The best plant media used in early seeding of oil palm is top soil with a thickness of 10 to 30 cm. Top soil is a layer of soil with high organic content, but at present its availability is rarely found so it needs a solution as its replacement. A alternative is to use organic material ash boiler with wood charcoal. This study aims to determine the effect of ash boiler and wood charcoal as a medium to grow against some indicators of oil palm seed growth. This research was conducted from February to May 2017. The experimental design used was a complete randomized design of one factor, namely P0: 100% sub soil (without wood charcoal and boiler ash), P1: 10% ash boiler + 10% charcoal wood + 80% sub soil, P2: 20% ash boiler + 20% wood charcoal + 60% sub soil, P3: 30% ash boiler + 10% charcoal + 60% sub soil, P4: 10% ash boiler + 30% wood charcoal + 60% sub soil. Each treatment was repeated 2 times, so there were 10 experimental units. Each experimental unit consists of 2 samples. The total number of plants is 20 plants. The result of the research shows that the ash of boiler and charcoal have significant effect on the growth of plant morphology (plant height, stem diameter, number of leaves), and plant physiology (boimassa plant), but no significant effect on leaf area parameters.
