Abstract

UD Company. Dua Putra has a total of 5 employees and applies a working time system of 2 shifts per day. In the production process, the target that must be met within 1 month is 2000 packing crackers. From April 2022 to September 2022, the production output of tofu crackers experienced an average decrease of 17% or 350 packs of crackers. This is caused by changes in working hours and operator fatigue during production activities. In overcoming this problem, overtime is an option to complete the predetermined targets. The aim of this research is to measure the level of work fatigue and determine the factors causing fatigue among workers in tofu cracker production operators and provide suggestions for improvements to reduce the level of worker fatigue. The method used in this problem is the Bourdone Wirsma method, which is a simple measurement method that can determine mental work load and measure speed, accuracy and concentration as well as monotonous work in employees. From the analysis of the Bourdone Wirsma test method for speed levels, the results obtained were 80% of the weighted score results of "8.5", "8", "13", "12" in the quite good category. Accuracy calculations for tofu cracker production employees obtained results of 100% from the weighted score results of "5", "5.5" in the doubtful category. Concentration calculations get results of 100% from the weighted score results of "5.5", "5" and "4.5" in the doubtful category.

Abstract

PT. Karunia Selaras Abadi is a flexible packaging converting company. 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.
