Ergonomic Analysis of Work Fatigue and Eyestrain Among Wig Makers at PT. SCI Indonesia Kupang City

Abstract

Making wigs is a job that requires high accuracy and concentration. If done for a long time with a heavy workload, and work posturethat is not ergonomic can cause work fatigue and eyestrain on workers. The work environment in the form of lighting that does not meet the requirements also affects the health of the worker's eyes. Eyestrain occurs because workers try to see small objects at close range with a long duration of time, causing tension in the eye muscles. Eyestrain can affect the work health and safety of workers, so as to reduce work productivity. This study aims to determine the relationship between work postureand eyestrain, the relationship of workload with eyestrain and the relationship of lighting to eyestrain in wigs of PT. SCI Kupang City. This research is a descriptive analytic study with cross sectional design. The sample in this study were 48 workers at PT. Kupang City SCI taken using Simple Random Sampling technique with data analysis using Chi Square test. Work Attitude, Workload and Lighting in the study are independent variables, while eyestrain and work fatigue are the dependent variable. The results showed that there was a significant association between work posture and work fatigue (p = 0,000 <0,05) and eyestrain (p = 0,011 <0,05). Workload was also associated with work fatigue (p = 0,002 <0,05) but had no relationship with eyestrain (p = 0,201> 0,05). The result also found that lighting was significantly related to both work fatigue (p-value = 0,002 <0,05) and eyestrain (p-value = 0,004 <0,05). It is expected that workers work with an ergonomic work posture so that eyestrain can be reduced, utilizing rest time as optimal as possible so that the perceived eyestrain and work fatigue can be reduced. Workers need to work with ergonomic posture, workloads and lighting in order to reduce work fatigue and eyestrain, which may lead to an increase in productivity.
