Analysis Work Shifts, Workload and Smoking Habits on Blood Pressure Through Job Fatigue in Lift and Transport Operators of The New Makassar Container Terminal

Introduction: Occupational health disorders, including physical, mental, and cardiovascular diseases such as hypertension and hypotension, are increasing due to work factors such as workload, work shifts, and smoking habits, which impact workers' health and productivity. The objective was to assess work shifts, workload, and smoking habits on blood pressure through job fatigue in New Makassar Container Terminal lift operators.Methods: This quantitative study used an analytic observational design with a cross sectional approach, conducted at PT Pelindo New Makassar Container Terminal from September to October 2024, with a sample of 170 operators and data analysis through chi-square test and logistic regression using SPSS.Results: The results showed that work shifts and physical and mental workload had a direct effect on job fatigue, while smoking habits had a direct effect on blood pressure, but there was no direct effect of work shifts and physical workload on blood pressure. In addition, physical and mental workload influenced systolic and diastolic blood pressure through occupational fatigue.Conclusions: For workers, it is important to organize sleep routines, apply ergonomic techniques in physical workload, maintain mental resilience with rest time, and reduce smoking to prevent health risks. For companies, it is important to design a fair work shift system, conduct physical workload analysis with ergonomists, provide psychological support, and establish a clear smoking policy in the workplace.
