PT. XYZ wants to increase production efficiency, achieve optimal production capacity, and calculate the right amount of operator at the work station, so line balancing analysis is carried out. Line balancing method used is Rank Positional Weight, Largest Candidate Rules, Kilbridge-Wester, and Moodie Young, and identify performance line before and after the line balancing are carried out using the software ProModel. The data collection technique used is a time study using a stopwatch. The beginning balance efficiency is 42.79%, 6 work station and smoothness index 115.15 minutes, with Rank Positional Weight, Largest Candidate Rules, Kilbridge-Wester, and Moodie Young Method, the balance efficiency is 82.98%, 3 work station, and smoothness index 77.02 minutes. The final result of the simulation using ProModel is a product output of 7 units, which indicates that the simulation results on the new planning line exceed the specified target of 3 units in 8 hours without the need for overtime work. There was a reduction of operators from 4 to 3 people.
