P PT. PG Rajawali II unit Subang merupakan sebuah perusahaan yang bergerak di bidang argo industri, produk yang dihasilkan adalah gula. Proses produksi PT. PG Rajawali II unit Subang adalah continuous process. Penelitian ini dilakukan di stasiun puteran, karena tingginya nila ikumulatif downtime yang menyebabkan terhambatnya proses produksi dan menyebabkan tidak tercapainya target produksi. Adapun tingginya nilai kumulatif downtime yang terdapat di stasiun puteran, merupakan kumulatif dari 17(tujuh belas) mesin, yang terbagi atas 2(dua) jenis mesin, yaitu 10 (sepuluh) mesin low grade centrifugal (LGC) dan 7 (tujuh) mesin high grade centrifugal (HGC). Berdasarkan hasil diagram pareto, yang memiliki nilai downtime yang terbesar adalah mesin high grade centrifugal (HGC). Adapun hasil diagram pareto mesin high grade centrifugal yang ditentukan berdasarkan nilai downtime adalah mesin high grade centrifugal 7 (23.98%), mesin high grade centrifugal 6 (20.58%), mesin high grade centrifugal 4 (14.46%), mesin high grade centrifuga /1 (7.92%), mesin high grade centrifugal 5 (6.37%), mesin high grade centrifugal 2 (3.27%) dan mesin high grade centrifugal 3(3.19%). Perhitungan nilai overall equipment effectiveness (OEE) yang dilakukan bertujuan untuk mengidentifikasi nilai efektivitas mesin. Nilai efektivitas mesin dengan perhitungan overall equipment effectiveness (OEE), yang menunjukkan bahwa mesin high grade centrifugal 7 dan high grade centrifugal 6 memiliki nilai OEE dibawah 95%. Nilai overall equipment effectiveness (OEE) untuk mesin high grade centrifugal 6 pada bulan Juni 2011 dan bulan Agustus 2011 masing-masing bernilai 94.94% dan 94.03% , serta mesin high grade centrifugal 7 Juli 2011 dan bulan Agustus 2011 masing-masing bernilai 94.32% dan 93.61%. Usulan perbaikan sistem perawatan mesin high grade centrifugal 7 dan high grade centrifugal 6 dilakukan dengan pendekatan lean assessment dan lean preparation. Lean assessment melakukanevaluasi terhadap proses total productive maintenance (TPM) high grade centrifugal 7 dan high grade centrifugal 6. Hasil lean assessment adalah interval waktu penggantian pencegahan dan interval waktu pemeriksaan serta waste of motion pada pengambilan tools dan komponen, kemudian pada tahap lean preparation memberikan usulan jadwal perawatan mesin untuk musim giling tahun 2012 dan meminimasi waste of motion dengan pembuatan shadow board berdasarkan metode 5S.

P PT. PG Rajawali II unit Subang ids accompany engaged in the agro industry, the resulting product is sugar. PT. PG Rajawali II unit Subangtype of production process is continuous process. The research was conducted at the puteran station, because of the heigh value of cumulative downtime that causes inhibition of the production process and the lead to failure to achieve production targets. The high value of cumulative downtime contained in puteran station, is a cumulative of 17 (seventeen) machine, which is divided into 2 (two) types of machine, namely 10 (ten) machines low grade centrifugal (LGC) and 7 (seven) machines high grade centrifugal (HGC). Based on the result of pareto diagrams, which has the largest value of downtime is high grade centrifugal machines. The result of pareto diagrams high grade centrifugal machines which is determined based on the value of machine downtime is high grade centrifugal 7 (23,98%), high grade centrifugal 6 (20,58%), high grade centrifugal 4 (14,46%), high grade centrifugal 1 (7,92%), high grade centrifugal 5 (6,37%), high grade centrifugal 2 (3,27%) and high grade centrifugal 3 (3,19%). The calculation of the vlue of overall equipment effectiveness (OEE) conducted aiming to identify the effectiveness of the machine. Value of the effectiveness of the machine with the calculation of overall equipment effectiveness (OEE), which indicates that the high grade centrifugal 7 machine and high grade centrifugal 6 machine has an OEE value below 95%. The overall equipment effectiveness value for high grade centrifugal 6 machine in June 2011 and August 2011 each worth 94,94% and 94,03%, as well as high grade centrifugal 7 machine in July 2011 and August 2011 respectively worth 94,32% and 93,61%. Proposed improvement maintenance system of high grade centrifugal 7 machine and high grade centrifugal 6 machine approach with lean assessment and lean preparation. Lean assessment to evaluate the process of total productive maintenance (TPM) fo high grade centrifugal 7 and high grade centrifugal 6 machine. The result are lean assessment and preventive replacement time interval inspection and waste of motion on the uptake of tools and components, then lean on the stage of preparation to give suggestions for the engine maintenance schedule in 2012 milling season and minimize the waste of motion with the making of shadow boards based on the 5S method.
