Faktor-faktor yang Berhubungan dengan Kelelahan Kerja pada Pengemudi Truk PT. Komol di Medan

Abstract

Work fatigue is one of the occupational health problems that can affect the performance, safety, and productivity of truck drivers. Factors such as age, mental workload, driving duration, rest time, and sleep quantity and quality are suspected to influence the level of work fatigue. This study aimed to determine the factors associated with work fatigue among truck drivers at PT. Komol in Medan. This research employed a quantitative approach with a cross-sectional design involving 38 truck drivers as respondents. Data were analyzed using the Spearman correlation test. The results showed that 26 drivers (68.4%) experienced moderate fatigue, followed by 6 drivers (15.8%) with mild and severe fatigue. Variables such as age, mental workload, driving duration, rest time, and sleep quantity had no significant relationship with work fatigue. However, sleep quality showed a significant relationship with work fatigue (r = 0.528; p = 0.0001) and was categorized as a moderate correlation. This indicates that the poorer the drivers, sleep quality, the higher their level of work fatigue. It can be concluded that the psychological factor, namely sleep quality, is the dominant variable associated with work fatigue among truck drivers at PT. Komol Medan.
