The Relationship Between Noise and Temperature to the Level of Work Fatigue in Workers in the Cutting Section

Abstract

Work fatigue is a decrease in or inability for a person to carry out work activities. Fatigue can occur due to factors in an unsupportive work environment. Workers in the cutting section at Small and medium-sized enterprises (SMEs) Gunungkidul Yogyakarta, Indonesia, carry out the production process in the form of cutting natural stone every day, which is at risk of being exposed to noise and rather high temperatures. Based on the results of the initial measurements, it was found that the level of noise intensity and temperature in the production area exceeded the allowable threshold value. This study aims to determine the relationship between the physical work environment, including noise and temperature, and worker fatigue and then analyze how much influence these factors have and which factors have the most dominant influence on worker fatigue. This study used multiple linear regression methods with randomly selected samples from several SMEs in Gunung Kidul, Yogyakarta. The results showed that the noise factor with a t test value of (4,086 > 2,093) indicated that noise had a positive and significant effect on work fatigue, while the temperature factor, based on the results of the T test, had a calculated T value of (1,787 < 2,093), which means that the temperature has no significant effect on work fatigue. With a coefficient of determination of 0.508 or an effect of 50.8% on worker fatigue.
