An Evaluation of the Effectiveness and Reliability of the Machines Using the Overall Equipment Effectiveness (OEE) and Reliability Analysis Methods at the Tea Leaf Processing Plant PT. Perkebunan Nusantara IV Unit Bah Butong

Abstract

The Tea Leaf Processing Plant PT. Perkebunan Nusantara IV Unit Bah Butong is an industry that motion in the tea leaf processing. The process of production is supported by a number of interdependent machines and tools to achieve optimal productivity. The problem is that frequent machine failure is considered to be interfering with the production process resulting from maintenance’s un-maximum. Thus need evaluation of the effectiveness and reliability of machines in order to maximize maintenance in order to reduce machine failure. The purpose of this study is to know the value of the effectiveness production engine by calculating the value of the Overall Equipment Effectiveness (OEE), identifying the effectiveness of the engine by measuring six big losses, calculating the reliability of the engine by adding analysis and improving the maintenance schedule to improve engine efficiency, and predicting OEE’s values after maintenance repairs were made. The value of this journal is expected to be an input to companies to know the value of the effectiveness machines and the reliability of the entire machine system if maintenance is done according to the recommended MTTF maintenance program.

“…Calidad=piezas buenas/producción real Las piezas buenas es el total de producción que no necesitan retrabajos o simplemente son piezas defectuosas u obsoletas. La producción real es la cantidad de piezas que se producen en un periodo determinado, esta variable se ve afectada por las micro paradas y la reducción de la velocidad establecida (Napitupulu & Rahmadsyah, 2020). La fórmula general del OEE total de los equipos está dada por el producto de los tres indicadores previamente calculados y con las consideraciones para cada variable, de esta manera disponibilidad, rendimiento y calidad son multiplicados, establecido mediante la siguiente ecuación.…”

“…(Ahuja et al 2019). (Napitupulu & Rahmadsyah, 2020), para la evaluación con indicadores OEE, es necesario partir desde la situación inicial, sin embargo, para la mejora de estos indicadores es necesario contar con una serie de herramientas que sugiere la metodología Lean Manufacturing.…”

Preventive Maintenance of Diesel Power Generators in Indonesia’s Manufacturing Industries

“…Proceedings of the International Conference on Industrial Engineering and Operations Management Istanbul, Turkey, March 7-10, 2022 Through machine maintenance, it is hoped that the continuity of operations and productivity of the supply of power in a factory can be maintained. Maintenance is all activities to maintain or maintain machines, facilities, and production equipment and make repairs or adjustments, as well as replacements needed so that a satisfactory production operational condition can be expected in accordance with what is planned (Napitupulu and Manik, 2020). The purpose of maintenance is carried out so that production capabilities can meet the needs of the company or organization, maintaining quality at the right level to meet what is needed by the production itself (Sahal et al, 2020).…”
