Operator haul truck Haul truck operator is one of the high-risk occupations in experiencing fatigue caused by the implementation of shift work, sleep quantity and quality disturbance, other related factors. The objective of this study was to analyze the relationship between shift work, quantity and quality of sleep, and other factors associated with fatigue on the haul truck operator. A cross-sectional study was conducted in this study using questionnaires of Fatigue Assessment Scale (FAS), measurement of stress using cocorometer, and measurement of sleep quantity and quality using fitbit among 196 male respondents who work as haul truck operator. The result of this study shown there is a significant correlation between the quantity of sleep (OR = 3,222, p = 0,028) and fatigue, also between the quality of sleep (OR = 2,800, p = 0.025) and fatigue. However, shift work has no significant correlation with fatigue. Other factors, including mental workload (OR = 2,296, p = 0,027), work environment (OR = 2,400, p = 0,014), monotonous work (OR = 3,371, p = 0,002), age (OR = 2,708, p = 0,005), and sleep hygiene (OR = 3,840, p = 0,001) also have significant correlation with operator fatigue in PT X.

Shift and on-call workers in the electricity sector have a high risk of experiencing fatigue, which impacts cognitive function, productivity, health and safety. This fatigue is influenced by work-related risk factors (on-call system, work shift, work period, workload) and non-work-related risk factors (age, sleep, nutritional status, side job, married status, disease history). The purpose of this study was to analyze the risk factors for fatigue in shift and on-call workers. The study used a cross sectional design with mixed methods. Quantitative data were obtained from 98 respondents using OFER, PSQI, NASA-TLX questionnaires, height and weight measurements, and supported by qualitative data through open interviews. The results of this study showed that workload was significantly associated with acute fatigue (p = 0.027; OR = 2.703) and chronic fatigue (p = 0.034; OR = 2.618). In addition, sleep quantity (p = 0.035; OR = 3.906) and married status (p = 0.003; OR = 4.354) had significant associations with acute fatigue. The conclusion of this study emphasizes the importance of implementing fatigue management and increasing self-awareness in managing fatigue.
Industrial modernization requires automatisation system to be implemented morecommonly. Shiftwork system is also done to ensure that production activity in industryor vital services, such as hospital, do not stop. These systems requires workers to alwaysbe alert which needs to be supported by optimum body function. Even so, these systemsincreases fatigue, stress, and drowsiness, lowering alertness and increases the risk ofincident and accident which are detrimental to health and safety. Aromatherapy is amethod using essential oils to evoke physiological and psychological reaction which iseasy to use and has high potential. This study aims to find the effect of aromatherapy onalertness in adults using systematic literature review based on article from 2000-2020.Database searches are conducted using 7 database which resulted in 16 articles whichfulfilled the inclusion criteria. The results of the study are as follow: peppermint issuggested to be the most effective type of aromatherapy to positively affect alertness orvigilance; followed by lavender, petitgrain, cinnamon, and I. helenium.
