Analysis of Effectiveness Measurement of Stretch Blow Machine Using Overall Equipment Effectiveness (OEE) Method

Abstract

This study aims to measure the effectiveness of the Stretch Blow machine at PT. X by calculating the Overall Equipment Effectiveness (OEE) value. Stretch Blow Machine is one of the machines used in the manufacturing process of plastic bottles. These machines often suffer damage so that targets and product quality are often not achieved. The purpose of this study was to determine the most dominant factor of the Six Big Losses on the Stretch Blow Machine. The method used in this research is descriptive quantitative. Based on the results of data processing and analysis, it shows that the average value of Overall Equipment Effectiveness OEE for the period January 2017-December 2017 is 43.89%, while the OEE World Class Value is> 85%. For that it is necessary to do research using quality control tools, namely Pareto and fishbone diagrams. The results of the data analysis with the Pareto diagram found that the largest Idling Minor and Stoppage Losses is 39.28%. The causes of Idling Minor and Stoppage Loses based on the results of the fishbone diagram analysis are lack of mechanical operator skills, unavailable engine spare parts, machine maintenance schedules are not running and the quality of engine spare parts is not suitable. The improvement plan of the factors causing Idling Minor and Stoppage Loses using 5W + 1H have to be implemented so that the Overall Equipment Effectiveness (OEE) value of the Stretch Blow Machine could be increased.
