Proposing Overhaul Maintenance Scheduling In Engineering Asset Management (Case Study: PT. Madu Baru PG. Madukismo)
Abstract
Maintenance is one part of production processes and maintenance that conducted spends
15% - 70% of production cost. By developing the maintenance scheduling, besides
decreasing the cost of the production, it should decrease the production cost. PT.
Madubaru is one of the companies that engaged in agro industry field located in special
region of Yogyakarta which are producing sugar (PG. Madukismo) and also spiritus (PS.
Madukismo). In PT. Madubaru, maintenance scheduling arranged by considering the
duration of activity and number of operators or labours, in which the maintenance is
occurred after the production period and being run for 5 months. This research took the
front factory as the object that run the drilling process of the sugar cane before to the
middle factory. The maintenance activity is divided into 4 groups. Each group has the
part of machine to be treated and duration with man power that already allocated. The
previous maintenance scheduling is never be evaluated its the effectivity based on the
cost and man power allocation. Genetic Algorithm (GA) is employed to process the better
maintenance scheduling for front factory. After the 6740 iterations, the result shows that
maintenance scheduling from GA gave the lower allocation worker and cost than the
initial scheduling.
