Abstract
Maintenance merupakan lini support process dalam model bisnis CIMOSA. Meskipun termasuk dalam support process namun dengan penanganan yang tepat akan memberi dampak penghematan yang besar. Studi kasus dalam penelitian ini yakni Machine Direct Order (MDO) pada lini produksi BOPP 6. Penelitian ini memberikan dampak untuk memudahkan aktivitas maintenance yang tepat dengan penanganan hanya terkonsentrasi pada komponen kritis saja. PT Trias Sentosa belum melakukan Preventive Maintenance dengan dasar perhitungan keandalan, hal inilah yang mendasari penelitian ini untuk dilakukan. Berdasarkan data kerusakan dan pengolahan penentuan kritis, maka didapatkan bahwa komponen Nip Roll MDO 6 dan 3 memiliki karakteristik sesuai distribusi yang telah diolah dengan software Weibull++6 yakni Weibull 2 Parameter, hasil MTTF dan MTTR menjadi dasar acuan dalam pembuatan jadwal preventive maintenance rekomendasi. Jadwal rekomendasi awal memberikan nilai opportunity cost sebesar Rp 8.588.646.566,40 dan dengan integrasi time to repair kondisi eksisting maka opportunity cost dapat diperkecil menjadi Rp 1.717.729.313,28. Dasar penentuan integrasi ini yakni dari pembandingan dampak availability terhadap opportunity cost pada original MTTF dan interval perawatan eksisting. Opportunity cost paling minimum yakni apabila jadwal rekomendasi awal diintegrasikan dengan nilai time to repair berdasarkan kondisi eksisting, hal inilah yang menjadi dasar dalam pembuatan jadwal skenario terbaru yang memiliki dampak opportunity cost terkecil.

Maintenance is a line of support in the business model CIMOSA process. Although included in the support process, but with the right treatment it will impact big savings. The case studies in this research namely Machine Direct Order (MDO) in BOPP production line 6. This study gives effect to facilitate maintenance activities appropriate to handling only concentrated on critical components only. Preventive Maintenance in PT Trias Sentosa not done on the basis of calculation of reliability, it is the underlying this research to be done. Based on data from damage and critical determination processing, it was found that the component Nip Roll MDO 6 and 3 have characteristics consistent distribution that has been processed with the software Weibull ++ 6 is Weibull 2 Parameter, MTTF and MTTR results are the basis in making preventive maintenance schedule recommendations. Schedule initial recommendations give the opportunity cost of Rp 8,588,646,566.40 and the integration time to repair the existing condition then the opportunity cost can be reduced to Rp 1,717,729,313.28. The basis for determining the integration of benchmarking is the impact of the availability on the opportunity cost with original MTTF and existing maintenance (time to repair) intervals. The most minimum opportunity cost is when the initial recommendation schedule is integrated with the value of time to repair based on existing condition, thus themost minimum impact of opportunity cost will be achieved.
