FACTORS RELATED TO WORK FATIGUE AMONG WORKERS AT PT. BOILERTECH IN INDONESIA PEKANBARU CITY

Abstract

Work fatigue is one of the occupational health problems often experienced by industrial workers due to high workloads and unfavorable work environment conditions. This condition can reduce productivity, increase the risk of work accidents, and negatively impact workers' physical and mental health. This study aims to determine the factors associated with work fatigue in workers at PT. Boilertech Indonesia, Pekanbaru City in 2025. This type of research uses a quantitative method with a cross-sectional design. The study was conducted with 30 respondents as a sample selected using an accidental sampling technique. Data were collected through an Industrial Fatigue Research Committee (IFRC) questionnaire and temperature measurements using a digital thermometer. Analysis was carried out univariately and bivariately using a simple linear regression test with a 95% confidence level (α = 0.05). The results showed that most workers experienced moderate levels of fatigue with an average score of 8.93. The bivariate test showed no significant relationship between age and work fatigue (p = 0.804) and no significant relationship between length of work per day and work fatigue (p = 0.714). However, there is a significant relationship between work environment temperature and work fatigue (p=0.000; r=0.731) with a very strong positive relationship direction.
