Abstract
PT. XYZ is a company engaged in construction and manufacturing. The company focuses on paving production. Where there is a problem with paving printing machines in carrying out production, there are many productions that do not reach the target or the production process does not run optimally. The purpose of this study is to find out the performance of paving molding machines, especially in the components that most often experience damage to paving molding machines. Based on historical data on machine damage, a paving molding machine is a machine that has had the highest frequency of damage for 5 years, because this machine operates continuously to meet production targets and paving demand from customers. Reliability and Risk Centered Maintenance (RRCM) methods to be used to analyze a historical engine malfunction. The results obtained in the form of 7 proposed maintenance tasks are 2 scheduled on-condition tasks, 3 scheduled restoration tasks, 2 scheduled waste tasks. In addition, the average maintenance time interval for pillow blocks is 7 months, iron molding is 11 months, and chain is 4 months. The total cost of proposed maintenance is lower than IDR 52,938,750 or 41.7% compared to the existing maintenance cost of PT. XYZ. The development of this research is to increase the application of RCM as a basis for maintaining the balance between preventive maintenance and corrective maintenance while optimizing maintenance costs to improve engine reliability by considering risk factors as an analysis.

Summary
Sektor industri menjadi sektor penting dalam pembangunan perekonomian Indonesia. Salah satu industri yang memberikan banyak manfaat dan perubahan yaitu industri konstruksi dan manufaktur. Penelitian yang dilakukan (Fang et al, 2019) hasil penelitian ini menunjukkan “Penerapan metode RCM dapat memberikan pengembangan strategi pemeliharaan yang sesuai dengan masalah pada komponen kritis, sehingga pengoperasian kereta api berjalan lancar”. Penelitian yang dilakukan (Sinha & Mukhopadhyay, 2015) hasil penelitian ini menunjukkan “Metode RCM memfokuskan penerapan pemeliharaan yang berpusat pada keandalan sistem guna meningkatkan kinerja mesin cone crusher dalam melakukan produksi”. Penelitian yang dilakukan (Atmaji et al, 2017) pada sub-sistem kritis mesin pesawat menjelaskan bahwa “Tujuan utama RCM adalah membangun prioritas mengenai desain yang mampu mendukung kegiatan pemeliharaan preventif dan mendapat informasi yang bermanfaat untuk meningkatkan desain komponen dengan keandalan, ketersediaan, dan pemeliharaan”. Penelitian yang dilakukan (Atmaji, 2015) hasil penelitian ini menunjukkan “Penerapan metode RCM menghasilkan jadwal pemeliharaan, interval waktu penggantian yang optimum dan total biaya pemeliharaan yang minimum untuk tiap komponen kritis”. Menurut (Selvik & Aven, 2011) menjelaskan bahwa “RRCM memiliki tujuan untuk menciptakan metode pemeliharaan yang akurat, fokus serta optimal agar mendapat keandalan (reliability) fasilitas yang maksimal dengan mengacu pada faktor risiko sebagai salah satu analisisnya”
