Analysis of Line Balancing to Increase Production Line Efficiency in the Car Battery Industry

Abstract

The automotive industry, in the form of electric cars, has entered Indonesia, making competition in automotive companies increasingly competitive, including the companies in this study that have had a positive impact, namely increasing demand for car batteries. In line with the development of electric cars, the company also developed new products, so the company installed an assembly line. but after the assembly line was running, productivity from production capacity and efficiency could not reach an average output of 823 units/day, the actual average output produced was only 622 units per day. There is a problem with line balancing on the assembly line which causes quite high waiting times at several stations, does not achieve production targets, and makes line efficiency less than optimal. Therefore the purpose of this study is to make improvements with the right Line Balancing method to be applied to achieve a suitable line balance and to find the Line Efficiency value that can be gained from the application of Line Balancing and how much the production capacity increases. The results of the research show that the Largest Candidate Rule method is the best method because it can increase the Line Efficiency value by 91.03%, the percentage of idle time or Balance Delay has improved, which has decreased to 8.97% and the total idle time is 21.3 seconds compared to the initial conditions. And can increase production capacity per day by 35.7%. This will be achieved consistently if the company can continue to improve employee skills by conducting training and increasing operators' motivation.
