Line balancing analysis on finishing line dabbing soap at PT. XYZ

Abstract

PT. XYZ is a company that engaged in cleaners and detergent industry. The unbalance of the production line which is caused by the unequal of work responsibility distribution in each work station that caused the performance of line balance doesn't work properly. With line balancing in production system will increase the efficiency of production. Line balance method that used to solve these problems is Rank Positional Weight method, Kilbridge-Wester method, Largest Candidates Rules, and Moodie Young method. Beginning of efficiency is 55.73%, balance delay is 44.27%, and smoothness index is 3.96 seconds with 5 work stations. By using the Rank Positional Weight method, Kilbridge-Wester method, Largest Candidates Rules, and Moodie Young, obtained efficiency results of 69.66% and balance delay of 40.34% with a total of 4 work stations. The results for smoothness index using Rank Positional Weight method and Moodie Young is 2.96 seconds, while Kilbridge-Wester method and Largest Candidates Rules is 2.675 seconds. Therefore, Kilbridge-Wester method and Largest Candidates Rules is the best method because the efficiency increased by 13.93%, balance delay decreased by 3.93%, and smoothness index decreased by 1.285 seconds from the beginning line.
