Abstract

Operation Excelence is needed at manufacturing process in order to achive optimum cost. One of method is using line balancing. It work by increasing efficiency and remove bottole neck at workstation.. The purpose of this research is to increase productivity in the work path of diabetes drug production line, it means that all work stations can achieve optimum output, eliminate or reduce material accumulation by identifying line balances at work stations. By using the Line Balancing method. The method used is the Ranked Position Weight (RPW) heuristic method. As result productivity was increasing, with line efficiency from 58.36% to 80.25%, balance delay from 41.64% to 19.75%, a decrease in the amount of material accumulation between work stations on the diabetes drug production trajectory from 25 - 1175 doos / hour to 4 - 174 doos / hour, and eliminating the bottleneck on the trajectory of diabetes drug production.

Abstract

PT. XYZ is engaged in manufacturing automotive products has products such as altenator and motor starter for automobile vehicles. The problem that exists in the company is experiencing a shortage of products to sell or not being able to meet the demand for the number of products requested. The purpose of this study is to determine optimal production planning and raw material inventory control in order the company can minimize stock outages. The methods used in this study are moving average, weight moving average, and exponential smoothing for forecasting. As for raw material inventory control, it uses the economic order quantity, safety stock, and reorder point methods. The results of this study obtained is weight moving average method n = 3, because it has the smallest error rate, namely with MAD of 5,364, MSE of 39,447,784, and MAPE of 10.66%%. Meanwhile, raw material inventory control for 2022  obtained by using economic order quantity method, achived by directly order  11,243 units per year, with the number of orders every 55 times, then the total inventory cost is IDR 673,725,000. In the safety stock method for 2022, it is 3,564 units with a reorder point of 7,128.
