Studi Penerapan Total Productive Maintenance (TPM) untuk Peningkatan Efisiensi Pada Pupuk Organik PT. Agro Energi Indonesia

Abstract

PT. Agro Energi Indonesia is a company engaged in organic fertilizer processing. The company faces the problem related to the machine efficiency caused by improper handling and maintenance of production machinery. This can be seen in the machine broke down of Bobcat s750 disrupting the organic fertilizer production on the whole. Furthermore, as a production efficiency improvement effort, the company was carried out the application of Total Productive Maintenance by measuring the machine effectivity of Bobcat s750 using the OEE (Overall Equipment Effectiveness) method. After that, it was conducted the six big losses calculation to find out the level of efficiency decrease on each factor of six big losses. Through the calculation result, the obtained value of OEE during the September 2018 to February 2019 period on the Bobcat s750 machine was between 82.813% and 89.13%. The ideal value of OEE was 85% obtained for 4 production months. Then, the biggest factors that influenced the value of OEE and being the priority to be eliminated on the Bobcat s750 machine were the Idling/Minor Stoppages factor of 48.35% and the Equipment Failures factor of 38.89%. Thus, the proposed improvement actions were the proposal of autonomous maintenance application, giving the training to the operators of Bobcat and workshop technicians, improving the frequency of Bobcat s750 machine maintenance, setting a standard of Bobcat s750 machine maintenance implementation, and improving control and awareness of the operators about the working environment cleanliness.
