Analisis Efektivitas Mesin Reng dengan Menggunakan Metode Overall Equipment Effectiveness (Oee) dan Fault Tree Analysis (Fta) di CV. Ali Griya, Semarang

摘要

The analysis of reng machine effectiveness by using Overall Equipment Effectiveness (OEE) and Fault Tree Analysis (FTA) method in CV. Ali Griya, Semarang. The reng machine of CV. Ali Griya, which is used to produce lightweight steel roof with a kind V reng, has not fully worked effectively. This is indicated by the presence of downtime, speed losses, and produce products that are not according to standards that have been determined. This study aims to measure and determine the level of effectiveness of reng machine using Overall Equipment Effectiveness (OEE) method, identify factors that cause six big losses by using Fault Tree Analysis (FTA), and proposes improvements to increase the effectiveness of the machine. From the research, OEE of reng machine reached an average of 57.55%, and still was below the ideal OEE (85%). Proposed improvements that recommended include the elimination of six big losses, develop a maintenance program, and provide training to improve the ability of maintenance and operations.
