UD Gajah Delta is a familly business managed by a husband and wife in the city of Sidoarjo, East Java. This trading business was started in the 2000s and still survives today. One of UD Gajah Delta's strategies to survive today is to maintain quality and pay attention to every detail of the voice of the customer. In fulfilling the demand for pans, meatball boilers, rice boilers, and soup bowls, UD has 3 factories and dozens of employees who help with the production process. Besides that, to help the success of the production process, there are various types of machines such as cutting machines, press machines, press roll machines, and punch machines. In order to maximize the production process at UD Gajah Delta, it is necessary to calculate the need for raw materials and the number of machines used to assist the production process. Calculating the need for raw materials and machines used can use the method of operation process chart (OPC) and multi product process chart (MPPC). So that it will know the amount of raw material requirements and the right machine in the production process.Keywords: Raw material, MPPC, OPC, Machine

Abstract

PT.X merupakan perusahaan yang bergerak di bidang industri kertas yang menggunakan limbah kertas daur ulang untuk dijadikan kertas baru. Dalam proses produksi sering mengalami downtime yang disebabkan kerusakan mesin dan mengalami cacat produksi berupa kertas putus, akibat PT.X menerapkan corrective maintenance, yaitu melakukan perbaikan ketika mesin mengalami kerusakan. Untuk mengatasi hal tersebut penelitian ini dilakukan untuk merubah perawatan pada PT.X menjadi preventive maintenance untuk memaksimalkan paper machine dan mengurangi downtime. Setelah menggunakan diagram pareto 80:20 dihasilkan komponen kritis boiler, screen, dan wire pada paper machine 1 sendangkan roll, vacuum, dan wire pada paper machine 2. Hasil perhitungan didapatkan interval preventive pada kompnen boiler 43 hari sekali, komponen screen 34 hari sekali, komponen wire paper machine (1) 49 hari sekali, komponen roll 78 hari sekali, komponen vacuum 42 hari sekali dan komponen wire paper machine (2) 19 hari sekali dengan nilai keandalan sebesar 50%. Sehingga didapatkan perkiraan pengeluaran pertahun untuk preventive maintenance sebanyak Rp.145.500.000,-
