Abstract
PT. Kutai Timber Indonesia merupakan perusahaan yang memiliki bisnis utama berupa pemasaran dan pembuatan plywood dan produk-produk berbahan dasar kayu. Salah satu faktor yang mempengaruhi kualitas produk yang dihasilkan adalah mesin. Berdasarkan data kerusakan pada tahun 2017 chipper area di area produksi particle board PT. Kutai Timber Indonesia merupakan area produksi yang memiliki tingkat kerusakan yang tinggi, dimana mesin yang sering mengalami kerusakan adalah big chipper, pada mesin ini terdapat dua sistem utama yakni feeding roll dan rotor chipper. Dalam menjaga kinerja mesin perlu dilakukan kegiatan maintenance, kegiatan maintenance yang dilakukan PT. Kutai Timber Indonesia selama ini adalah plant maintenance. Namun kenyataannya kedua sistem tersebut sering mengalami kerusakan saat produksi sedang berlangsung hal ini mengakibatkan terganggunya proses produksi dan biaya kerusakan yang membengkak oleh karena itu, dilakukan penelitian untuk menentukan waktu optimum preventive maintenance dengan biaya minimum pada sistem feeding roll dan rotor chipper mesin big chipper di area produksi particle board menggunakan model Geometric Process. Model ini digunakan karena dapat menggambarkan kerusakan kedua sistem tersebut yang memiliki trend. Hasil analisis menunjukkan bahwa waktu optimum preventive maintenance masing-masing sistem berbeda dan rata-rata biaya jangka panjang yang dihasilkan lebih murah dibandingkan dengan biaya yang selama ini dikeluarkan perusahaan.

PT Kutai Timber Indonesia is the company that has a main business namely marketing and manufacturing of plywood and wood-based product. One factor that influences the quality of the product produced is the machine. Based on data on damage in 2017, chipper area in the particle board production area of PT. Kutai Timber Indonesia is a production area that has a high level of damage, where the machine that is often damage is the big chipper, in this machine there are two main systems namely feeding roll and rotor chipper. To maintain engine performance, maintenance activities which is conducted by PT. Kutai Timber Indonesia has been a plant maintenance. In fact, both systems often suffer damage while production is in progress, this results in disruption of the production process and the damage costs are inflated, therefore, research is carried out to determine the optimum time of preventive maintenance with minimum costs in the feeding roll and rotor chipper systems in big chipper machines in the particle board production area using the Geometric Process model. This model is used because it can describe the damage of two systems that have a trend. The results of the analysis show that the optimum preventive maintenance time for each system is different and the average long-term costs produced are lower that the costs incurred by the company.
