Maintenance scheduling system is very important for a company to reduce total maintenance cost. Maintenace scheduling will be done on hydraulic seal and oil burner pipe that are components of press machine for hot forming process. Scheduling model will consider labor cost, production loss cost, and spare part cost. The aim of this model is to determine the interval of maintenance by optimizing cost. This calculation will reduce total maintenance cost between 35,07 % and 90,73 % of the previous total maintenance cost.
