Abstract

PT Japfa Comfeed Indonesia, Tbk. Unit Margomulyo merupakan perusahaan yang berfokus pada kebutuhan pakan ternak khususnya ternak ayam broiler. Proses produksi pakan ternak dibantu oleh beberapa mesin salah satunya adalah mesin Pellet Mill. Mesin Pellet Mill merupakan mesin yang berfungsi untuk pembentukan pellet pada pakan ternak. Beberapakali mesin Pellet Mill mengalami kerusakan ditengah proses produksi, sehingga mengganggu proses produksi. Jika mesin mengalami kerusakan, perusahaan akan melakukan corrective maintenance atau perbaikan. Perbaikan pada mesin tidak selamanya efisien karena semakin sering mesin mengalami perbaikan maka keandalan mesin akan semakin menurun dan laju kerusakan semakin meningkat seiring bertambahnya waktu. Penelitian ini bertujuan untuk menentukan waktu optimum perusahaan melakukan tindakan pemeliharaan pada mesin Pellet Mill 5.12 dan 8.12 berupa pengecekan seluruh komponen dan melakukan penggantian komponen utama yaitu Die Press. Metode yang digunakan pada penelitian ini adalah Geometric Process yang menyatakan bahwa setelah mesin mengalami perbaikan maka dianggap memiliki kinerja dan keandalan yang menurun secara linier. Hasil penelitian menunjukkan waktu optimum untuk pemeliharaan mesin Pellet Mill 5.12 adalah pada kerusakan ke-8 dengan estimasi rata-rata biaya jangka panjang sebesar Rp 3.812.096 perjam dan pada mesin Pellet Mill 8.12 pada kerusakan ke-7 dengan estimasi rata-rata biaya jangka panjang Rp 7.344.398 perjam. ============================================================ PT Japfa Comfeed Indonesia, Tbk. Unit Margomulyo is a company that focuses on animal feed needs, especially broiler chickens. Livestock feed production process is assisted by several machines, one of them is Pellet Mill machine. Pellet Mill machine is machine that serves to form animal feed into pellet. Some of Pellet Mill machines are damaged during production process, thus disrupting the production process. If the machine is damaged, the company will perform corrective maintenance or repair it. Repairing the engine is not always efficient because the more often the machine is repaired then the reliability of the machine will decrease and the rate of damage will increase along time. This study aims to determine the optimum time for the company to take preventive maintenance on the Pellet Mill 5.12 and 8.12 in the form of checking all components and perform component replacement. The method used in this study is Geometric Process which states that after the machine has repaired then considered its performance and reliability would be decreases linearly. The result showed that the optimum time for preventive maintenance of Pellet Mill 5.12 was on the the 8th damage with the estimated cost of Rp 3.812.096 and the Pellet Mill 8.12 machine on the 7th damage with the estimated cost of Rp 7.344.398
