Line balancing is a series of work stations (machinery and equipment) that are used in manufacturing products. Line balancing usually consists of a number of work areas called work stations handled by one or more operators and it is possible to be handled using a variety of tools. The purpose of research in the case of the production line is to obtain the lowest RPW weight value from the production PT. X with Rank Potential Weights method which is optimal for production lines without bottlenecks at the work station. The allocation of elements at work stations is limited by main constraints, namely zoning constraints. This method is usually better known as ranked positional weight system (RPW). The first step is to make a precedence diagram and precedence matrix. Calculate the positional weights for each element obtained from working time of that element. Calculating the production process time, each work element requires a cycle time using stopwatch time study. The method of ranking positional weight system (RPW) in this case the Production Track is in the initial condition with a cycle time of 1857 seconds and there are 5 work station. The known value of balance delay is 26.74%, efficiency is 37.34%.
