Maintenance of production machinery is crucial for maintaining the quality of the production process. At PTPN VI Solok, there is a significant issue with the Close Roll Printing Machine, which plays a vital role in the tea pressing process. This study aims to understand the maintenance requirements of the Press Cap Roller Machine and provide maintenance recommendations using the Failure Mode and Effect Analysis (FMEA) and Reliability Centered Maintenance (RCM) methods. FMEA is utilized to examine and track potential failures, while RCM aims to select, develop, and create effective maintenance strategies. The FMEA analysis revealed that the crankshaft is the predominant cause of failure, with a Risk Priority Number (RPN) value of 17.07%. RCM analysis indicated that the Mean Time To Failure (MTTF) for components ranges between 1433.4 and 1811 hours. Recommendations for improvements include checking the crankshaft rotation to ensure it runs smoothly and performing maintenance according to the schedule. Additionally, regular gearbox inspections are crucial, such as checking oil levels, oil circulation conditions, gearbox area leaks, and replacing the gearbox according to the component's lifespan to maintain optimal performance. Other maintenance suggestions involve direct prevention of failure sources and appropriate maintenance, regular bearing replacements and inspections as per the schedule, and routine checks of electrical current and temperature. The implementation of FMEA and RCM methods is expected to provide more structured and effective solutions for maintenance issues, thereby maintaining the quality of the tea production process. This approach also aims to extend the machine's lifespan and reduce unexpected maintenance costs, thus enhancing the company's operational productivity and efficiency.

This investigation involved micro, small and medium enterprises (MSMES) engaged in home furniture manufacturing services. The conventional method used by these craftsmen usually uses tools that are easily available around us, using a woven or plaited system. Commonly used materials include Manau, bamboo, ropes and nails. This work is also said to pose a risk, because rattan, if it has been scraped or thinned to make it flexible, can endanger the craftsman. However, there are complaints from craftsmen who say that nowadays not many people want to use furniture made from handicrafts or from natural materials. People who have used a lot of home furniture made from various materials such as plastic, glass and others. In making this craft, a heating system is also used to heat the Manau with fire so that it can be easily bent to form parts of the craft framework.

The success of a project is uncertain. There is a possibility that the project was successful or failed. Some of the risks that may occur in the project include the arrival of goods or the completion of work late from the time set, design changes due to obstacles in the field, as well as other risks. It is therefore necessary to study the project risks to identify potential problems that may occur and make decisions to reduce risks and increase the likelihood of success of the project. In order for risk management to be performed, the owner must know the steps in evaluating the project and the steps in the implementation of risk management. This study discusses the development of algorithms for project evaluation and risk management. The resulting algorithm is then implemented to the CC-II civil construction project at Indarung VI Project. The results of the implementation show that the project is not running in accordance with the plan. The dominant factors causing delays include BOQ miscalculation by consultants, inadequate and slow decision-making mechanisms, and details of workmanship changes.
