Efficiency Analysis of Sterilizer Machine Using Overall Equipment Effectiveness (OEE) Method at PT. Gersindo Minang Plantation, Pasaman Barat

Abstract

PT. Gersindo Minang Plantation is a company in the field of processing of palm oil to Crude Palm Oil (CPO). The boiling section uses three sterilizer machines. Machine number three has many disruptions during operation so that causing decreased level of productivity. Therefore, special attention should be paid to the maintenance of the sterilizer machine so that the production process is effective and efficient. Total Productive Maintenance (TPM) is a management principle to improve productivity and production efficiency by using machinery effectively. The first step in improving production efficiency is by measuring the effectiveness of the sterilizer machine. The purpose of this study is knowing the value of Overall Equipment Effectiveness (OEE) on sterilizer machine number 3 and knowing the factors causing it. The value of OEE in the period of January - December 2016 was 57.08%. The value is low and has not reached the standards required by Japan Institute of Plant Maintenance (JIPM) is more than 85%. Factors that affect the low value of OEE are speed loss factors which include idling, minor stoppages and reduced speed. Companies need to conduct training to operators and technicians in order to improve the ability to overcome the problems on the sterilizer machine so that companies can apply autonomous maintenance.
