Analysis of The Determinants of Work Fatigue in Aircraft Maintenance Engineers at Sultan Hasanuddin International Airport Makassar

Abstract

Introduction: Occupational Safety and Health (OSH) is important to prevent accidents and fatigue experienced by 32,8% of workers, while in the aviation industry, the shortage of technicians and 24-hour shift work system increases the risk of fatigue that impacts the safety and quality of aircraft maintenance. 
Method: This research is an analytical observational study with a cross sectional quantitative approach to 106 of 145 Aircraft Maintenance Engineers at Sultan Hasanuddin International Airport Makassar, using KAUPK2, NASA-TLX, PSQI questionnaires, as well as pulse oximeter and BMI measuring instruments, with chi-square analysis and logistic regression through SPSS. 
Results: The results showed a significant relationship between several variables with work fatigue, namely age (p=0,001) tenure (p=0,002) smoking habits (p=0,000), sleep quality (p=0,002) marital status (p=0,000) physical workload (p=0,000) and mental workload (p=0,008). The logistic regression model proved feasible (p=0,000) and was able to explain 47,6% of the variation in work fatigue, with the most influential variables being age, marital status, physical workload, and smoking habits.
Conclusion: This study concludes that job burnout in Aircraft Maintenance Engineers is significantly influenced by age, smoking habits, physical workload, and marital status, thus workload management, quality of life improvement, and work-family balance support need to be prioritized.
