KAJIAN KINERJA DAN PROSES PRODUKSI RIPPLE MILL HASIL FABRIKASI DEPARTEMEN MAINTENANCE DI PABRIK KELAPA SAWIT LIBO

Pabrik Kelapa Sawit (PKS) merupakan tempat untuk mengolah tandan buah segar kelapa sawit menjadi CPO (Crude Palm Oil) dan PKO (Palm Kernel Oil) . PKS merupakan perusahaan yang menggunakan berbagai mesin dan alat-alat lain yang mendukung proses produksinya. Salah satu mesin yang digunakan untuk mengolah nut yaitu ripple mill. Ripple mill merupakan alat yang berfungsi untuk memecah nut sehingga cangkang dan kernel dapat terpisah. Ripple mill diharapkan memiliki kinerja yang sesuai standar. Kinerja ripple mill dinilai dari efisiensi dengan standar lebih dari sama dengan 96 % , kernel pecah kurang dari sama dengan 15 %, serta perawatan komponen sesuai life timenya. Rotor bar 600 jam/set/unit, stator bar 600 jam/set/unit. Karena pentingnya menjaga kinerja ripple mill, perlu adanya pengadaan ripple mill baru. Pada umumnya, proses pengadaan ripple mill baru, membeli dari vendor. Namun di PKS libo, ripple mill di fabrikasi oleh departemen maintenance. Penelitian ini bertujuan untuk mengetahui kinerja ripple mill hasil fabrikasi departemen maintenance di PKS Libo, serta mengetahui perbandingan biaya antara ripple mill hasil fabrikasi departemen maintenance di PKS Libo dengan membeli dari vendor. Hasil penelitian yang telah dilakukan menunjukkan bahwa kinerja ripple mill hasil fabrikasi departemen maintenance di PKS Libo dengan efisiensi rata-rata 98,560 % dengan kernel pecah rata-rata 13,978 %. Perawatan untuk life time komponen ripple mill: rotor bar 441 jam/set/unit dan stator bar 441 jam/set/unit. Biaya ripple mill hasil fabrikasi departemen maintenance di PKS Libo adalah Rp 10.840.059,60 dengan biaya ripple mill hasil pembelian dari vendor Rp 59.500.000. Dengan demikian, Biaya yang dapat dihemat adalah Rp 48.659.940,40.rnrnPalm Oil Mill (PKS) is a place to process fresh oil palm fruit bunches into CPO (Crude Palm Oil) and PKO (Palm Kernel Oil). PKS is a company that uses various machines and other tools that support the production process. One of the machines used to process the nut is ripple mill. Ripple mill is a tool that functions to break the nut so that the shell and kernel can separate. Ripple mill is expected to have performance that meets standards. The performance of ripple mill is assessed by efficiency with a standard of more than or equal to 96 %, kernel break less than or equal to 15 %, and component maintenance according to the life time. Rotor bar 600 hours per set per unit and stator bar 600 hours per set per unit. Because of the importance of maintaining the ripple mill's performance, it is necessary to procure a new ripple mill. In general, the process of procuring a new Ripple Mill buys from the vendor. But in PKS libo, ripple mill is fabricated by the maintenance department. This study aims to determine the performance of the mill ripple produced by the maintenance department in Libo PKS, as well as to find out the cost comparison between the ripple mill from the maintenance department fabrication in Libo MCC by buying from the vendor. The results of the research that have been carried out show that the performance of the mill mill results from the maintenance of the maintenance department in Libo MCC with an average efficiency of 98.560 % with an average kernel breaking of 13.978 %. Maintenance for component life time of ripple mill: rotor bar 441 hours per set per unit and stator bar 441 hours per set per unit. The cost of ripple mill from the maintenance department at PKS Libo is Rp. 10,840,059,60 with the cost of ripple mill purchased from the vendor Rp. 59,500,000. Therefore, the saved cost is Rp. 48,659,940,40.
