PT. YGI, an automotive manufacturing company, uses the Press Injection GB-36 machine in its production process. However, this machine frequently experiences failures, causing high downtime and reduced production efficiency. This study aims to identify the types of failures, determine the most critical components, and propose a maintenance system using the Reliability Centered Maintenance (RCM) approach. The method used is descriptive qualitative, involving FMEA (Failure Mode and Effect Analysis), Logic Tree Analysis (LTA), and maintenance action selection. Data were collected through observations, historical failure documentation, and interviews. The analysis results indicate that components such as the injection nozzle, heating, and clamping are the most critical, contributing over 80% of total failures based on Pareto analysis and the highest RPN values in FMEA. Proposed maintenance actions include Condition Directed and Time Directed approaches. Additionally, the maintenance system is supplemented with standard operating procedures (SOP) and routine inspection schedules to improve machine reliability and reduce production downtime. This study is expected to enhance the efficiency and productivity of the Press Injection GB-36 machine at PT. YGI through the appropriate implementation of RCM.

PT. Dian Swastatika Sentosa generates electricity through a private thermal power plant. This company produces steam and electricity for paper mills. The company hopes to meet its steam and electricity needs in 2023 with a boiler with a load capacity of 180 tons and a maximum capacity of 220 tons. However, from February to July 2023, that goal was not achieved. The most common problems faced by this company are the failure to conduct preventive inspections and timely machine maintenance, as well as the failure to carry out necessary repairs. Delays in machine repairs, which result in inconsistent machine downtime schedules to meet customer demand, leading to damage to boiler equipment, causing abnormal boiler operation and reduced steam production. This research aims to design equipment to withstand operational impacts using failure mode and effects analysis (FMEA) with the Soft Systems Methodology (SSM) and reliability-centered maintenance (RCM) techniques. The RCM method assists in identifying the processes that must be followed to guarantee that a machine or system performs as intended. RCM can also be used to design, choose, and create alternative maintenance methods that are focused on safety, operations, standards, and economics. For the entire problem in the investigation, a dynamic model is necessary. An analytical system is used in this model in order to recognize and duplicate the features of the overall system., as well as to provide repair solutions and address the burden of the problem. This research produces a presentation in the form of problem identification, causal loops, diagrams of machines that frequently experience failures, rich images of the causes and effects of the ball plate crusher liner damage, root cause definitions, and conceptual models for repair and maintenance. business productivity and debating process.

The instability of the economy and increasingly sharp competition in the industry requires a company to further enhance the efficiency of its operations. Treatment method that has been used is still corrective maintenance where engine maintenance activities undertaken to improve and enhance the condition of the engine so as to achieve the standards set at the level tersebut.Besarnya machine downtime which reaches up to 40% each month. Due to the growing number of downtime that occurs it will be increasingly detrimental to the productivity of a company. In this study used methods Realibility Centered Maintenance abbreviated to (RCM), which is to determine the optimal engine maintenance activities for the company. Reliability Centered Maintenance (RCM) is an approach that combines maintenance practices and strategies of preventive maintenance (PM) and corrective maintenance (cm) to maximize the life (life time) and the function of assets / systems / equipment at a minimal cost. Subjects studied machine is the machine Injection Molding, where the focus of engine components that will be examined as many as six parts: Barrel, Piston Injection, Toggle Clamping, Nozzle, Hydro Motor, Hopper. As for the category based on time (TD), the treatment provided in the form of component replacement schedule. Category finding damage (FF) recommended replacement components if the level of damage exceeds tolerable limits. Failure of components that include safety problem 13:33%, Outage System 80.00%, 6.67% Economic System. Of the total minimum downtime obtained Screw interval of 30 days, the crosshead link 11 days, Seal 13-day, 12-day screening. Downtime Screw impairment 37.21%, 41.15% crosshead link, Seal 24.56%, and 29.32% Screening

This study aims to know the cost of designing maintenance using the Reliability Centered Maintenance method. Engine and fuel control, is a fuel engine system and fuel control system; in charge of distributing and measuring fuel from the fuel storage tank, to the combustion chamber. Gas turbine or  component area (Combustor), functions as a distributor of fuel used in aircraft systems and plays a role in carrying out its operation (Boeing 737-400 Aircraft Maintenance Manual). Reliability is the possibility of a component or system to be able to operate and/or carry out its functions. The function has been assigned to certain operating conditions and in a certain environment for a predetermined period of time. Thus, reliability is the probability that it will not fail or be able to perform its function for a period of time (t) or more. In the analysis of preventive maintenance financing, which is carried out when the reliability value reaches 70%, 60% and 50%, respectively, it is obtained for each component.
