EFFICIENCY IMPROVEMENT IN THE PROCESS OF FIREPROOF STEEL DOORS
Keywords:
Work Study, Fireproof Steel Door, Efficiency ImprovementAbstract
The objective of this research is to increase the efficiency of fireproof steel door process. The company's products have increased orders while production capacity is limited. It is therefore not possible to produce and deliver on schedule. It was discovered that some processes in the production process resulted in waste. The research process begins with studying thoroughly all fireproof steel door process. Then, use the Why-why Analysis principle to identify the root causes and the ECRS principle to find potential solutions. According to the data analysis, some processes were still not operating at their maximum potential. Some employees did not work with full capability. Consequently, the process can be improved by rearranging the task orders and use tools to minimize travel distance such as trolley and buckets of door components. After improvement with a decrease in production time of components from 396.87 minutes to 320.17 minutes, increase line balancing efficiency from 74.81% to 75.98%, and increase productivity from 28 doors per week to 34 doors per week, or by 21.42%.
