Production planning and control are things that need to be done for every manufacturing company in regulating its production activities so that it stays on target. This research requires request data from January 2017 to 2019, and other supporting data to carry out the forecasting method and then proceed with disaggregated aggregates, rough-cut capacity planning, material requirement planning, and capacity requirement planning. The results of the best forecasting calculations were using neural networks, aggregate and disaggregated planning in the form of a mixed shift and overtime scheduling totaling Rp. 3,837,237,500, rough-cut capacity planning does not have a lack of resources, material requirement planning using the silver meal method and the Wagner Within algorithm with the result is IDR 11,110,385,953 for 15 materials during the 2020 period, and in capacity, requirement planning there is a shortage of 9.9% for painting machines and 9.8% for packaging. The best solution for the problem of lack of painting and packaging machines is to add overtime hours with a total cost of Rp. 389,170,000 and 498,750,000.
