Study of Shift Work, Quantity and Quality of Sleep with the Occurrence of Fatigue at Universitas Indonesia Security, 2017

Shift work is one solution to increasing productivity. However, it can have several impacts, one of which is the disruption of the circadian rhythm, causing a decrease in the quality and quantity of workers and consequent fatigue. This study aims to establish the correlation between shift work, the quantity and quality of sleep, and the occurrence of fatigue. It is a cross-sectional study, conducted on security at Universitas Indonesia from May to June 2017, with 150 respondents. The instruments of the study were Industrial Fatigue Research Committee (IFRC) and PittsburghSleep Quality Index (PSQI) questionnaires, as well as an objective measurement of the quantity and quality of sleep through the actigraph (fitbit blaze) tool. The results show that 76 people, or 50.7 percent of repsondents, suffered from severe fatigue, while 74 (49.3%) had mild fatigue. The quality and quantity of sleep cannot directly affect the occurrence of fatigue, but in the literature there is a relationship between the variables. This study found no correlation between 2:1 and 4:2 working shift with regard to the occurrence of fatigue due to lack of sleep or its quality.
