Background: Work fatigue had the potential to cause work accidents that had an impact on losses to the company. This study aimed to analyze the level of subjective-work fatigue and evaluated the effect of workload on fatigue in the production area at The Crumb Rubber Factories of Padang City, West Sumatra, Indonesia. Methods: The research respondents were all workers in the production area in the three largest crumb rubber factories in Padang, totaling 348 workers. The respondents consisted of 135 workers in the wet division and 213 workers in the dry division. Subjective fatigue analysis uses the Industrial Fatigue Research Committee (IFRC) questionnaire method. Measures workload based on Indonesian Standards No. 7269 of 2009 concerning Workload Assessment based on Calorie Level according to Energy Expenditures. Results: The percentage of work fatigue in the production area was 26.32% light level, 72.63% medium level, and 1.05% heavy level. The workload had a significant effect on work fatigue, with a P value of 0.003. Conclusion: On the basis of the results of multiple regression analysis of all the variable characteristics of the respondents and work area, the most influential factor affecting the occurrence of fatigue in a crumb rubber factory was the workload. All crumb rubber factories in Padang should make improvements related to workload in controlling work fatigue.
