Description The frequent occurrence of unplanned maintenance of curing machine on PT XYZ car tire production line is an indication of ineffectiveness implementation of the preventive maintenance. Unplanned downtime caused increasing of lost production time and failure products during setup, and also high cost maintenance. The company must improve the effectiveness and efficiency of the maintenance system performance through updating the maintenance schedule for obtaining high availability of the machine. The purpose of this study is to identify the components which cause the failure of the curing machine and give the recommendation of the appropriate maintenance interval. Weibull distribution method is used to get the index value of fit time to failure of machine components, analyze the component failure rate, calculate the mean time between failure (MTBF) as the expected lifetime of the component. The obtained result showed that there were two critical components with an indication of the increasing failure rate, as during wear-out (β value> 1), which are namely cylinder press and EPV with an MTBF value of 89 days for cylinder presses and 231 days for EPV. The results of this study propose for updating the curing machine PM schedule. the adding pressure valve and EPV on PM activities and using the its expected lifetime as its PM interval should be considering. it will minimize unplanned downtime
Seringnya terjadi kegiatan perawatan (downtime) tidak terencana mesin Curing pada line produksi ban mobil PT XYZ merupakan indikasi adanya ketidakefektifan perawatan terencana (PM) yang diterapkan perusahaan. Downtime tidak terencana menyebabkan line produksi berhenti dan kehilangan waktu berproduksi, meningkatnya jumlah produk gagal saat setup, dan tingginya biaya perawatan mesin produksi. Perusahaan perlu meningkatan efektivitas dan efisiensi kinerja system perawatan melalui pembaharuan jadwal perawatan agar availability mesin tinggi. Tujuan penelitian ini adalah mengidentifikasi komponen penyebab kegagalan fungsi mesin curing dan menghasilkan rekomendasi waktu interval perawatannya yang sesuai. Metoda distribusi Weibull digunakan untuk mendapatkan nilai index of fit time to failure beberapa komponen kritis mesin, menganalisa laju kerusakan komponen, menghitung nilai mean time between failure (MTBF) komponen sebagai durasi expected lifetime komponen tersebut. Hasil yang diperoleh menunjukkan bahwa terdapat dua komponen kritis pada mesin curing dengan indikasi laju kerusakan seiring waktu (nilai β>1), yaitu silinder press dan EPV dengan nilai MTBF sebesar 89 hari untuk silinder press dan 231 hari untuk EPV. Hasil kajian ini mengusulkan pembaharuan jadwal PM mesin curing agar mempertimbangkan penambahan kegiatan PM baru yang mengakomodir nilai durasi expected lifetime dari komponen-komponen penyebab mesin breakdown, sehingga dapat meminimalkan downtime tidak terencana.
