Abstract

ABSTRACTWork fatigue is the body's defense mechanism designed to avoid the body from overharm possibilites. Fatigue is characterized by a shift in both physical and mental state that lowers one's capacity for and endurance during work. It was established from the initial survey that 5 employees (or 50%) had moderate category fatigue and 5 employees (or 50%) had severe category fatigue. The purpose of this study was to ascertain the link between work tiredness and both physical and mental burden. A cross sectional analytic observational research design was adopted by for this study, and simple random sampling was used for the sampling method. The total sample population of this study are 87 workers. The NASA-TLX questionnaire, a reaction timer, and the 10-beat method of measuring pulse were all employed in this study. The Somers' test and the ordinal logistic regression test were employed as data analysis approaches. The findings of the bivariate analysis using the Somers'd test revealed a significant association between physical workload and work fatigue with a p-value of 0.000. According to the findings of the multivariate study, physical workload had a 7,028 times greater impact on job fatigue.

Abstract

An industrial development is always followed by technological developments, especially in the textile industry which in the process cannot be separated with the help of machines. One of the negative impacts of this development is the noise from activities that use machines. Noise can be interpreted by the brain as a stressor or a trigger for stress. This study aims to determine the relationship between noise and work stress on operators at PT Kusumaputra Santosa. This type of research is analytic observational with a cross sectional approach. The sample of this study were 43 workers in the spinning division at PT Kusumaputra Santosa. The sampling technique in this study used a purposive sampling technique. To measure noise using a Sound Level Meter (SLM). While the bivariate analysis technique used to determine the correlation between noise and work stress is the Somers'd test. The results of the study using the Somers'd test showed that there was a correlation between noise and work stress on the spinning operator with a p-value of 0.000 and correlation (r) = 0.516 (medium correlation strength). Suggestions for further research need to add other variables or factors that can affect work stress that have not been studied in this study, such as work relations, organizational structure, work atmosphere and work climate. For companies, it is necessary to upgrade personal protective equipment with better quality than before and comfortable to wear and for spinning workers, they need to wear earplugs that have been provided by the company.

Abstract

The rapid development of industrialization has resulted in the emergence of problems in the world of work, namely the emergence of work accidents. Work accidents can occur due to unsafe actions and unsafe condition. Physical workload affects the physiological condition of workers, workers who receive physical workloads that exceed capacity can cause fatigue which results in feelings of boredom and decreased concentration and alertness of workers, so that from these conditions will cause workers to experience negligence or unsafe actions while working,The sampling technique in this study used a total sampling technique with a total of 70 respondents. To measure the physical workload using a pulseoximeter, measuring work fatigue with the KAUPK2 questionnaire, and measuring unsafe actions with a questionnaire. The bivariate analysis technique used is the Somers'd test and the multivariate analysis used is the ordinal logistic regression test. The statistical test results show that the physical workload variable has a p-value = 0.000 (<0.05) and the work fatigue variable has a p-value = 0.000 (<0.05). Based on the results of the ordinal logistic regression test, it is known that the variable most related to unsafe actions is work fatigue with a wald value of 16,014.
