Abstract:
Increasing demand customer makes company should prepare more in production facility. It consists of production planning, available capacity, and material. Because the forecast calculation is not always accurate, company needs to determine the production planning that can be able to accomplish the entire demand. This research is focus in line XYZ wherein needs other support company to fulfill the demand given in current condition, which is subcontract. The capacity subcontract is maximum 600 units/ day. By having the data collection, there is probability to re-arrange the production activity whereby the subcontract usage can be minimized and available capacity in regular time will be increased. In order to achieve the goal successfully, the right techniques are chosen, such as forecasting, aggregate planning, capacity planning, and balancing job. Forecasting technique calculates the demand customer in next period (monthly) to prepare the production activity. Then, aggregate planning is established for assisting the proposed production activity by using the balancing job. In addition, the demand and available capacity should be compared to adjust the each requirement. There is 75.92% reduction of using subcontract and 49.53% increment of available capacity in regular time.
