Air Traffic Controller (ATC) is a service provider that regulates traffic in the air, especially airplanes to prevent planes from getting too close to each other and collisions. Increasingly crowded flight schedules the level of responsibility and workload of Air Traffic Controller (ATC) operators is increasingly numerous and this has an impact on the mental burden and fatigue felt by air traffic controller officers. This study aims to determine the sex relations, work shifts, Mass Index Body (BMI), and workload on work fatigue at the Air Traffic Controller operator at Sultan Hasanuddin Airport in Makassar. This research is a quantitative study with a cross-sectional design with a sample size of 65 people. Data were collected by conducting interviews. The instrument used was a data analysis questionnaire using the Continuity Correction test. The results of this study indicate that of the 65 respondents there was no significant relationship between sex and work fatigue (p = 1,000), there was a relationship between work shifts and work fatigue (p = 0.015), there was no relationship between Body Mass Index (BMI) with fatigue (p = 0.064), and there is a relationship between workload and work fatigue (p = 0.021). The results of this study concluded that there was no relationship between sex and body mass index on fatigue and there was a relationship between work shifts and workloads at the Air Traffic Controller operator at Sultan Hasanuddin Airport in Makassar. It is expected that the Air Traffic Controller (ATC) operator should regulate and maintain the diet and intake of nutrients consumed, utilizing good rest time in between the controls so as to prevent the occurrence of errors felt by the Air Traffic Controller (ATC) operator.
