Abstract

Operations division employees in the telecommunications industry often face high mental workloads due to complex tasks, tight deadlines, and demands for accuracy and speed in their work. Excessive mental workload risks causing stress and reducing productivity. This research aims to evaluate the level of mental workload of PT Z operations division employees using the NASA-TLX method. NASA-TLX measures workload based on six main aspects: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration Level. Data collection was carried out through questionnaires, then analyzed to obtain the average Workload Weighting Level (WWL). The results of the analysis show that the average WWL value is 74.61, which is categorized as high. The main factors contributing to high mental workload include task uncertainty, tight deadlines, long hours working in front of the computer, and intensive multitasking. As corrective steps, this research recommends adjusting workload, providing sufficient rest time, and improving the ergonomics of the work environment. It is hoped that these findings can help companies manage employee workload to improve their welfare and productivity.

Abstract

PT XYZ is a manufacturing company in the paper industry with a continuous production system, making machine reliability a critical factor in maintaining smooth processes and high product quality. A vital system within the Cutter Strachain Henshain Machine (SHM) is the tension measurement system, which regulates paper web tension during the handling process. Field observations at PT XYZ revealed recurring disturbances caused by tension reading failure, which created significant discrepancies between Human Machine Interface (HMI) readouts and actual paper web conditions. While Reliability Centered Maintenance (RCM) is widely studied, its application to vintage, highly sensitive paper-tension control loops operating continuously for over two decades represents a distinct socio-technical operational gap. This study aims to analyze the maintenance strategy of the SHM tension measurement system using the RCM method to address this critical gap. Using a descriptive empirical approach incorporating structured observation, historical maintenance logging, and technical interviews, the system's operational functions, functional failure, and failure modes were systematically mapped. The analytical findings demonstrate that the primary point of failure stems from localized sensor contamination and localized degradation, severely compromising tension reading accuracy. Implementing an RCM-guided maintenance strategy, specifically through scheduled condition-directed maintenance and structured functional testing, is recommended. Quantitative projections indicate that these interventions can reduce total machine downtime by up to 15.4%, optimizing continuous production stability and mitigating cascading cutting defects.

Abstract

In the manufacturing industry, effective machine maintenance is essential to ensure production continuity and prevent downtime. PT KHAI faces performance degradation and damage to the automatic valve parts in its soy blending tanks, leading to significant production losses. This study analyzes the maintenance of these components using the Reliability Centred Maintenance (RCM) method. The novelty of this research lies in its specific application to piston-actuated butterfly valves within the liquid handling systems of the food processing industry, a specialized area that remains under-explored compared to heavy machinery or power plant sectors. The methodology involves system identification, Failure Mode and Effect Analysis (FMEA), Logic Tree Analysis (LTA), and Task Selection. The results identify critical failure components, including actuators, bearings, seals, packing valves, solenoid valves, limit switches, and control systems. The proposed maintenance strategy consists of time-directed tasks for four components, condition-directed for one component, and finding failure for three components. In conclusion, this study provides a new framework for mitigating hidden failures in automated actuation systems, offering a replicable maintenance model for ensuring high-hygiene production efficiency in the food industry.
