PT XYZ operate the machine Cincinati Double Gantry F since 1987. However, during the operating there are problems such as failure of the process that affect the performance of the machine so that the impact on the losses of the company, namely a decrease in revenue. Based on the damage data for the month of January 2016 – December 2018, the subsystem Axis and Electrical Panel & Control is a critical subsystem of the results of the risk matrix with the frequency of the highest damage, namely a total of 33 and 21. Therefore, the necessary steps to reduce losses that occur with conducting research to analyze the value of Reliability, Availability, Maintainability and Safety Analysis (RAMS). The results of the RAM by using the modeling of RBD based on the subsystem selected results obtained value of the reliability a subsystem of the Axis is lower than the Electrical Panel & Control. The time required to restore the subsystem Axis to normal range 1 hour (98%) and subsystems of Electrical Panel & Control ranged from 1 h (96%). Based on the evaluation standard IVARA World Class Maintenance Key Performance Indicators with leading indicators and lagging has reached the target of 95%. The results of research on the safety analysis at the time of the time interval of 16 hours a subsystem of the Axis is lower than on Electrical Panel & Control on the level of Safety Integrity Level However at the time of the time interval 80 hours, a subsystem of the Axis does not reach the target SIL according to standard IEC 61508.

INTRODUCTION (Use “Header 1” Style) In PT XYZ Machine Cincinati Double Gantry F which is a CNC machine. Machine Cincinati Double Gantry F has several subsystems that are integrated into the unity of the system unit that works to produce the bones of the wing of the plane As for the product that is produced in detail i.e. Drive Ribs, Joint Angle, Support Clear, Intercostal space lower, Joint plate, Reinforcing Angle, Nose Angel, Intermediate Ribs, Chord Wise. See the operational life of the machine has had a long operational period. This will affect the reliability of the system itself and do not close the possibility of failure on the machine in carrying out its functions. Addressing these objectives to be achieved of this research is to determine and analyze the value of Reliability, Availability, Maintainability (RAM) and determine the level of security by performing analysis of safety by using Safety Integrity Level (SIL). Where SIL is the level of security of a system if the value of the SIL the lower the this means that the level of security the machine is getting worse. Therefore, this study was conducted to determine the value RAM and security analysis of critical subsystem that was selected. The determination of the critical subsystem using the risk matrix where the consider the amount of damage that occurs on the sub system. Here is the data frequency of damage to the subsystems of the machine Cincinati Double Gantry F of the years 2016, 2017, and 2018: brought to you by CORE View metadata, citation and similar papers at core.ac.uk provided by JP Fakultas Ekonomi dan Bisnis Unsoed (Universitas Jenderal Soedirman, Journal &...
