Abstract

PT. Industri Sandang Nusantara Unit Patal Lawang adalah perusahaan yang memproduksi benang. Kerusakan mesin merupakan masalah yang sering dihadapi perusahaan. Kerusakan mesin menyebabkan terhambat produksi benang,Untuk mengurangi tingginya downtime tersebut dibutuhkan suatu kebijakan perawatan yang optimal agar mesin dapat beroperasi secara maksimal. Pada penelitian ini menggunakan metode Reliability Centered Maintenance (RCM) II. Penelitian ini dimulai dengan penentuan mesin dan komponen kritis. Selanjutnya melakukan pengolahan data kualitatif dengan menggunakan metode Failure Mode and Effect Analysis (FMEA) untuk menentukan prioritas penangganan dari setiap jenis kerusakan komponen kritis, melakukan pemilihan kebijakan perawatan dengan menggunakan metode Reliability Centered Maintenance (RCM) II yang dituangkan pada RCM decision worksheet. Pengujian kesesuaian distribusi data Time to Failure (TTF) dan Time to Repair (TTR) menggunakan uji Mann. Distribusi TTF diperlukan untuk mengetahui sebaran waktu kerusakan, sedangkan distribusi TTR diperlukan untuk mengetahui sebaran waktu perawatan atau penggantian spare part. Selanjutnya melakukan perhitungan Mean Time to Failure (MTTF), Mean Time to Repair (MTTR), perhitungan interval perawatan, dan total biaya perawatan optimal. Hasil pengolahan data menunjukkan bahwa komponen kritis pada mesin Blowing OM berdasarkan frekuensi kerusakan mesin dan total downtime adalah komponen flat belt dan spike lattice. Hasil analisis interval perawatan adalah permukaan karet flat belt tidak rata sebesar 510 jam, karet flat belt longgar 260 jam, flat belt putus 580 jam, kayu spike lattice patah 620 jam, dan paku spike lattice patah 500 jam. Dari total biaya perawatan optimal diperoleh hasil Permukaan karet flat belt tidak rata sebesar Rp 7.973.519,82, karet flat belt longgar Rp 11.000.673,81, flat belt putus sebesar Rp 14.061.553,06, kayu spike lattice patah sebesar Rp 19.170330,63, dan paku spike lattice patah sebesar 30.880.512,66. Metode Reliability Centered Maintenance (RCM) II dibandingkan dengan total biaya perawatan sebelumnya terjadi penurunan biaya perawatan dalam mesin Blowing OM sebesar 10,27%.

English Abstract

PT Industri Sandang Nusantara Unit Patal Lawang relies on appropriate maintenance system to sustain production process. PT Industri Sandang Nusantara Unit Patal Lawang is a company which produces yarn. PT Industri Sandang Nusantara Unit Patal Lawang controls the spare part replacement of production facilities based on corrective maintenance and perventive maintenance. It replaces spare part only when it has been failure, without a decent periodic replacement schedule. Machine failure is a problem in company. Machine failure makes production in company can not optimally. Maintenance policy is needed to reduce the downtime so the machine can operate optimally. This research used Reliability Centered Maintenance (RCM) II method. This research begins with the determination of the critical engine and components. Furthemore, researcher is using Failure Mode and Effect Analysis (FMEA) to determine the handling priority of critical components damages and perform maintenance policy selection using RCM II as outlined in RCM decision worksheet. The next step was doing suitability test of the data distribution Time to Failure (TTF) and Time to Repair (TTR) using Mann test. TTF distribution is needed to determine the distribution of the time of damage, while the distribution of TTR is needed to determine the distribution of a maintenance or replacement of spare parts. The next step are calculate MTTF, MTTR, maintenance interval and optimum total maintenance cost. The result that the critical components is Blowing OM machine because the highest downtime. Based on the frequency of machine damage and total engine failure downtime are flat belt and spike lattice. The results of optimal maintenance intervals are 510 hours for unflat rubber flat belt, 260 hours for rubber flat belt looses, 580 hours for flat belt broke, 620 hours for broken wooden spike lattice, and 500 hours for broken nail spike lattice. The total cost of the optimal treatment results obtained for unflat rubber flat belt at Rp 7.973.519,82, rubber flat belt loose at Rp 11.000.673,81, flat belt broke at Rp 14.061.553,06, broken wooden spike lattice at Rp 19.170.330,63, and nail broken spike lattice at Rp 30.880.512,66. The total cost maintenance using RCM II compared to the total maintenance cost before has decreased the cost of maintenance cost in Blowing OM machine of 10,27 %.
