This company produces various types of plastic packaging for snacks, powdered drinks, soap, etc. This company produces more than 10,000 rolls and 1,000,000 bags every week so that the printing cylinders at PT. The Gift of Eternal Harmony reaches more than 3,000 items. The cylinder washing process is stressful for workers, thereby triggering fatigue which results in decreased productivity. Workers handle materials incorrectly using Manual Material Handling, causing workers to experience pain in their body parts. Workers' muscles receive continuous static loads over a long period of time, potentially resulting in musculoskeletal disorders. Thus, workers are asked to fill out the CMDQ questionnaire which aims to determine the level of ergonomic risk. Based on the CMDQ questionnaire, the body parts that workers often experience pain are the knee (left), shoulder (right) and lower back. Followed by an assessment of work posture using the OWAS method including the back, arms, legs and load, then completed with an assessment of work posture using the REBA method. There are 2 activities that have a high level of risk according to the OWAS method, washing cylinders using category 3 solvent, checking cylinders, category 3. For research on the REBA method, washing cylinders using solvents with a score of 8, checking cylinders with a score of 10, these results show that all activities require an improvement process.

Abstract

The study conducted at PT. Tjiwi Kimia aimed to assess the fatigue criteria and mental load experienced by production operators of cartoon box in the context of the company's 3-shift operation. Using the Bourdon Wiersma method for fatigue evaluation and the NASA TLX method for mental load analysis, findings revealed varying levels of fatigue and mental burden across different shifts. Notably, the morning shift exhibited "Good enough" speed fatigue but "Doubtful" accuracy fatigue, while the night shift showed "Enough" consistency fatigue. Furthermore, the mental burden was highest during the night shift, categorized as "High." These findings underscore the importance of addressing shift-related fatigue and mental load in industrial settings. Recommendations for implementing 3-shift rotations with weekends off and providing short breaks reflect potential strategies to mitigate worker fatigue and improve overall well-being. Future research could explore additional factors influencing worker fatigue and mental load, such as ergonomic interventions or technological advancements in production processes. Highlight: Shift Work Effects: Assessing fatigue and mental load in industrial settings. Evaluation Methods: Bourdon Wiersma and NASA TLX for worker analysis. Improvement Suggestions: Implementing 3-shift rotations and providing breaks. Keywoard: Fatigue, Mental Load, Production Operators, Shift Work, Industrial Setting

Abstract

One of the MSMEs engaged in the snack food sector and currently running is the taro chips business owned by Mr. Wahab which is located at Tambak Sari Village, Purwodadi Pasuruan, East Java. Business running for 1 year. Chips are snacks or snacks made from various ingredients such as flour and others, and also from tubers. Based on the results of interviews and observations obtained from consumers, the problem that is often complained of is the packaging used, which is thin plastic and easily torn or perforated. So that the condition of the chips is easily sluggish or not crispy. Kansei engineering is a technology that translates a customer's or consumer's feeling and image about a product which is then translated into design elements or in other languages, is a customer-oriented technology for product development based on computer science. The purpose of the Kansei engineering method is to make it easier for designers to gather consumer needs based on feelings or what can be called consumer psychology. The Kansei method will be integrated with the Analytical Hierarchy Process (AHP) to decide whether the new packaging is more feasible and good or not. The results showed that the packaging of taro chips was a simple design, bright color, and plastic material from the Kansei Engineering and AHP methods. The packaging is strong and durable so that it can maintain the crispness of the chips.
