Aldityawan Syahputra, Muhammad (2021) PENENTUAN KEBIJAKAN PERAWATAN DENGAN MENGGUNAKAN METODE RELIABILITY CENTERED MAINTENANCE II PADA MESIN GRANULATOR 02 PADA PROSES PRODUKSI PUPUK ORGANIK. Sarjana thesis, Universitas Brawijaya.
Abstract
PT Tiara Kurnia merupakan perusahaan yang bergerak dalam produksi pupuk organik. Mesin granulator berperan penting dalam proses pembentukan granule. Mesin Granulator 02 memiliki downtime yang disebabkan karena kerusakan komponen mesin dengan strategi perawatan yang digunakan yaitu corrective maintenance. Untuk mengurangi downtime komponen maka dilakukan identifikasi jenis kegagalan dengan menggunakan metode RCM II. Hasil dari penelitian menunjukkan bahwa komponen fanbelt dengan tindakan perawatan scheduled discard task yaitu dengan mengganti komponen fanbelt yang lama dilakukan setiap 460,117 jam sekali, komponen bearing dengan tindakan perawatan scheduled on-condition task yaitu memberikan pelumas pada bearing yang dilakukan setiap 36,242 jam sekali, komponen gearbox dengan tindakan perawatan scheduled on-condition task, yaitu dengan melakukan pemberian pelumas yang dilakukan setiap 30,207 jam sekali dan komponen motor listrik dengan tindakan perawatan yang dilakukan untuk komponen motor listrik adalah scheduled restoration task yaitu melakukan pengembalian resistensi melalui rewinding pada komponen motor listrik yang dilakukan setiap 1220,5164 jam sekali.
English Abstract
Muhammad Aldityawan Syahputra, Department of Industrial Engineering, Faculty of Engineering, University of Brawijaya, July 2021, The Determination of Maintenance Policies Using Reliability Centered Maintenance II of Pan 02 Machine in Organic Fertilizer Production Process, Academic Advisor: Bambang Indrayadi. PT Tiara Kurnia is a company engaged in the production of organic fertilizers. There are six main machines including screw, sifter, crusher, granulator, dryer and cooler. Pan machine plays an important role in the process of forming granules. Pan 02 machine has the highest downtime compared to other machines. Downime that occurs on the Pan 02 machine is caused by components failure. Pan 02 has 5 components, they are fanbelt, bearing, gearbox, electric motor and pulley. The company using corrective maintenance strategy by replacing failure components. To replace failured components, Pan 02 machine must be turned off. If there is failure to one component, the pan 02 machine is immediately turned off even though the other components can still operate. This results in a decrease in production capacity on the production line, so research is needed to reduce pan 02 machine downtime by determining preventive maintenance maintenance strategies and proper maintenance time intervals for each component failure. This study using Reliability Centered Maintenance II (RCM II) method. This method is used to determine the appropriate preventive maintenance strategy according to the failure caused by each component. Identification of system function and functional failure is carried out to determine the main function of the component. Then the identification of the failure of a component that can cause a failure using the Failure Mode and Effect Analysis (FMEA) method and calculate Risk Priority Number (RPN). There are four prioritized components including fanbelt, bearing, gearbox and electric motor. The prioritized components RCM II Information Worksheet, determine the type of distribution and parameter values for TTR and TTF data, calculate the MTTF and MTTR values, compile an RCM II Decision Worksheet, draw a current state map for Maintenance Value Stream Mapping (MVSM), analyze the causes of non-value added activities. using the Ishikawa diagram, describing the MVSM future state map, determining maintenance time intervals, calculating total maintenance costs and calculating component reliability. The results of the study indicate that the failure that occurs in the fanbelt component is a loose or broken fanbelt with scheduled discard task maintenance action by replacing the old fanbelt component with a new one every 460,117 hours, bearing components wearout and crack with scheduled maintenance action on-condition task by providing lubricant every 36,242 hours, worn gearbox components with maintenance action scheduled oncondition task by providing lubricant out once every 30,207 hours and electric motor components are with maintenance action scheduled restoration task to restore resistance through rewinding on electric motor components every 1220,5164 hours.
