Line Balancing Analysis in Ribbed Smoked Sheet Production Using Heuristics Methods (Study at PT. Wabin Jayatama, Serang, Banten, Indonesia)

Abstract

Production line balancing is done to increase line efficiency. Product flow between workstations is stated to be better when the percentage of line efficiency is higher. One of the factors that can hinder the smooth running of a line is a bottleneck. The occurrence of a bottleneck at the Ribbed Smoked Sheet production station, namely the milling and sorting station, at PT. Wabin Jayatama caused the production line to become unbalanced. The output that will be generated from this research is the efficiency level of the actual production line and the proposed design of a production line with more optimal efficiency, which will later be used as a consideration for recommendations to improve the performance of the company's production line. This research was carried out using the Kilbridge & Wester Heuristic method and the Ranked Positional Weights Heuristic method. The results of the line balance analysis showed that the production line had a higher line efficiency (LE) of 50.05%, an increase by 25.62% to 75.67%. The initial line balance delay (BD) of 49.55% can be reduced by 25.22% to 24.33%. Then the Smoothest Index (SI) of 447.74 can decrease by 360.51 to 87.23.
