This study aims to implement the Master Production Schedule (MPS) method for the production process at Soku Bakery. The authors conducted an interview with the owner of Soku Bakery regarding information about current production planning which includes inventory records, Bill of Materials (BOM), customer orders, production plans, and capacity. With the information, the Soku Bakery production process was optimized by making a Master Production Schedule (MPS) from the forecast that has been made. Aside from the data collection, the authors also collect literature from books, journals, and research related to Forecasting and the Master Production Schedule. The result shows that the implementation of the Master Production Schedule (MPS) can help Soku Bakery to adjust fluctuations in demand, minimize waste, prevent shortages, and scheduling errors, and provide more effective cost control and more accurate estimates of material, also requirements, and delivery dates.
