Analysis of productivity improvement using line balancing method (study case assembling line in PT XYZ)

To produce optimal production, it is necessary to adjust the placement of labor quantity, work line arrangement, facility layout and machine position, but to get accurate results as the initial calculation before production, it is necessary to schedule the right target with correct calculation, so there is no mistake in production, based on the results of previous research, the cause of cessation of production due to no production support materials, traffic jam between work stations, delay of order, and delay of delivery of goods. One of the factors that is quite influential in productivity is the production line and how many work stations. The efficiency of the production line between several related work stations is very influential in supporting the continuity of the company's production. This paper aims to analyze the cause of the delay in Line assembling so that the flow of raw materials and intermediate goods between work stations is better by using line balancing method. Delay, shortage of workers and the effectiveness of materials can be overcome. Based on the problems found in the assembling development section, it is known that there is congestion in the production process can be seen in station F because the cycle time is 6 minutes so the station G must wait for 4 minutes after the work. After the improvement cycle time reduced to 1554 seconds from the previous 1580 seconds, efficiency from 93.38% to 98.87%, with the method of line balancing obtained increased productivity and production efficiency.
