Plant maintenance undertaken at PKS Kertajaya is a system breakdown maintenance and preventive maintenance. Preventive maintenance is not carried out when the fresh fruit bunches processed a lot, so there will be breakdown maintenance. PKS Kertajaya does not have its own inventory concept in determining the amount of spare parts inventory. Reservation made based on estimates only based on the demand that has happened. The purpose of this study is to formulate the scheduling preventive maintenance on production equipment maintenance scheduling in a palm oil mill with an optimal cost of maintenance, to determine spare parts inventory by the number of low demand. This study conducted to get performance of production equipment maintenance using Overall Equipment Effectiveness, identifying and prioritizing equipment factory production by using Failure Mode and Effect Analysis, schedule preventive maintenance of production equipment with a total cost of optimal maintenance and spares inventory planning using the model of Economic order Quantity where demand assumed poisson distribution. Results of performance of equipment maintenance using Overall Equipment Effectiveness indicates that maintenance scheduled at a palm oil mill. Results of the Failure Mode and Effect Analysis is the ranking value Risk Priority Number to 30 components scheduled. Results of factory production equipment maintenance scheduling of oil palm is scheduling maintenance for 30 components with optimal charge at 51% level of reliability and can save as much as 17,5% of the cost without doing preventive maintenance. Results of spare parts planning is optimal total inventory cost.
