Abstract

Background: Work fatigue plays a large role in all industries in terms of performance, work safety, and work productivity. Oil and gas is an industry with a high level of occupational safety and health risks. Research of work-related fatigue is needed to detect critical risk factors early in order to prevent the adverse effect of work-related fatigue. Objectives: This study aims to analyze the prevalence of work fatigue in oil refinery workers at one of the oil refinery companies in Indonesia, and analyze the factors that influence it. Design and Methods: A cross-sectional study was conducted on 224 oil refinery workers. Questionnaire and work-related fatigue scales were used to assess demographic characteristics and work-related fatigue. A medical examination was applied to assess the health status of workers based on blood pressure, body temperature, and respiratory rate. The sound level meter and heat stress meter was used to measure noise and work climate. Cramer’s V correlation was applied to identify correlations between work-related fatigue and other parameters. Results: Work-related fatigue of 100% was found among workers, with categorized as low, medium, high, and very high in 9.38, 53.57, 30.35, and 6.7% of the workers, respectively. Work-related fatigue was significantly correlated with working period (p=0.028), health status (respiratory rate) (p=0.018), noise exposure (p=0.000) and work climate/heat stress (p=0.001). Conclusion: The companies should improve the health status of workers, reduce workload for aging workers, control noise, and control heat exposure in the workplace.

  • Environmental factors such as temperature, noise, and lighting conditions are determinants in fatigue and stress scales.

    “Factores como la temperatura, el ruido y las condiciones lumínicas son considerados determinantes en las escalas de fatiga y estrés [18], [19], [20], [21].”

    From Impact of ergonomics on work performance in the manufacturing industry: A systematic review (2025) · cites this paper as [20]

    The Introduction (page not available) lists temperature, noise, and light level as environmental factors contributing to work fatigue; the “Noise and heat stress exposure and WRF” section reports significant relationships for noise and high temperatures. The paper does not establish that these factors determine stress-scale scores, and it does not report a measured relationship between lighting and fatigue. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
