The spare part maintenance of cake breaker conveyor with reliability centered spares method

Abstract

The company that this research conducted is a manufacturing industry that produces CPO. Many machines in the production section need maintenance activities so that existing machines can work without inhibiting the production process. At seed processing station, there is CBC machine that experienced frequent occurrence damage. The machine applies corrective maintenance regardless of reliability machine production components, consequently, often occur sudden machine damage. Calculation of time interval-based maintenance policy scheduled discard task and needs a replacement component (spare part) that should be available are concerned with an optimal using method of Reliability-centered Spares (RCS). Based on the results of the calculations are based on a policy scheduled discard task then obtained a policy to perform maintenance on a screw conveyor components is 91 days, hangers and bearings are 40 days, jig-drilled couplings is 21 days. The result of the method of RCS acquired number of screw conveyor parts needs with this type of repair of repairable spare is 3 units for one year, while jig-drilled couplings with this type of repair repairable, need spare part 27 units for a year, as well as the hangers and bearing with this type of repair of repairable spare part, needs 21 units for one year.
