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.

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.

Waste is one of the problems faced by many countries in the world, including Indonesia. Indonesia is one of the world's largest waste contributor developing countries. Waste can come from restaurants, factories, companies, schools, government agencies, households, etc. Domestic organic waste management is still a serious environmental problem, this is characterized by the high contribution of organic waste to national waste generation and limited capacity of landfills. Ecoenzymes are one of the alternative approaches developed in the use of organic waste. However, the development of ecoenzymes towards a wider production scale still faces the main challenge in the form of product quality variability, especially related to the stability of physico-chemical properties. This study aims to analyze the physico-chemical characteristics and variability of the quality of the eco-economy based on fruit, vegetable, and mixed waste materials as the basis for quality control and process stratification The study method used an experimental design with three treatments of 1:3:10 (sugar:waste:day) for 90 days under anaerobic conditions. The quality parameters analyzed included acidity (pH) and turbidity (NTU), which were measured using a digital pH meter and a calibrated turbidimeter. The data were analyzed statistically descriptively. The results showed that fruit-based ecoenzymes produced a lower and more stable pH (average 3.21 ± 0.15) compared to vegetable waste (average 3.9 ± 0.42). The turbidity level is low (<15 NTU), while vegetable waste produces a higher pH (3.95 ± 0.42) with high turbidity (< 50 NTU). From an industry perspective, vegetable-based ecoenzymes demonstrate the need for stricter process control and standardization to ensure product consistency in mass production.
