The Influence of Working Hours Duration on the Fatigue Level of ATC Personnel in the Approach Control Procedural Unit in Banjarmasin, Indonesia

Abstract

This article analyzed the effect of working hours on the fatigue level of Air Traffic Controller (ATC) personnel in the
Approach Control Procedural unit at Syamsudin Noor International Airport, Banjarmasin. The research's background
highlights the vital role of ATC in ensuring flight safety, where long working hours can lead to fatigue, decreased
alertness, and circadian rhythm disturbances, ultimately increasing the risk of incidents. Therefore, this study aimed to
measure the impact of working hours on fatigue and identify related factors. The research used a descriptive quantitative
approach. A total of 20 ATC personnel were selected as the sample using a census sampling technique. Primary data
was collected through questionnaires with a Likert scale and then analyzed using SPSS to test for validity, reliability,
normality, simple linear regression, Pearson's correlation, and a T-test. The results show a significant and positive effect
of working hours on the fatigue level of ATC personnel. The simple linear regression analysis yielded a regression
coefficient of 0.864 with a significance value of 0.002 (p < 0.05), indicating that an increase in working hours
significantly raises fatigue levels
