As health professionals whose main task are providing care during childbirth, 40.8% of midwives suffer from musculoskeletal disorders at neck and 24.5% on upper back due to poor repetitive and frequent work posture they need to do over a long time while assisting childbirth such as bending, tilting the body to the left and looking toward the birth canal. A study claimed that midwives had a very high risk to suffer from MSDs. This study aimed at analyzing the correlation between elbow and parturition bed height with the risk of musculoskeletal disorders among midwives while assisting childbirth at the hospital. Method: This cross-sectional design research was determined using non-probability sampling technique involving 11 midwives in the hospital delivery room. The examined variables covered age, period of working, anthropometry, parturition bed, posture, and MSDs using a measurement sheet, REBA and Nordic Body Map Questionnaire as the research instruments. The data is presented in the cross tabulation from computer analysis data program and in description. Results: As much as 91 % midwives were at the age of 26-45 years old with >10 years of experience that was about 72.7%; 3 midwives had BMI score > 29; 81.8% midwives had high score level of musculoskeletal disorders risk, 81.8% midwives did not set their parturition bed with appropriate elbow height; and the value of contingency coefficient from elbow and parturition bed height with musculoskeletal disorders was 0.707. Conclusion: There is correlation between elbow and parturition bed height with musculoskeletal disorder of midwives when assisting childbirth process at hospital.Keywords: childbirth, ergonomics, midwife, musculoskeletal disorders

Introduction: A hospital as a health service facility needs to provide safe infrastructures, especially during disasters. The evacuation route is a safety support facility that can be used by everyone. A previous study states that when disasters occurred, nurses in the hospital did not know how to evacuate due to the difficulty in accessing the evacuation route. This study aims to analyze the relationship between the employee characteristics and knowledge of the evacuation route utilization. Methods: The study used an inferential analytical quantitative method. The population in this study was 178 temporary employees. The stratified random sampling technique was used to gain a sample of 64 people. The variables analyzed in this study were age, work period, education level, training, and knowledge of the temporary employees. Moreover, questionnaires were filled by the temporary employees as a technique of data collection. The Chi-Square test was used as the technique of data analysis. Results: The results of the study show that in the highest number, 40.6% of the employees are 31-40 years old, 56.3% of the employees have 1-10 years of service, 39.1% of the employees have a diploma degree, and 65.6% of the employees have participated in the evacuation route training.In addition,based on the bivariable analysis, the authors find that there is a relationship between employees’ age and knowledge (p value = 0.036), work period (p value = 0.039), education level (p value = 0.029), and training (p value = 0.029). Conclusion: There is a relationship between the employee characteristics and knowledge regarding the evacuation route utilization.Keywords: disasters, employees, evacuation route, hospitals, knowledge Keywords: disasters, employees, evacuation route, hospitals, knowledge

Introduction: The increased use of computers in the era of technological advances had an impact on the eye health called Computer Vision Syndrome (CVS), a compound eye problem caused by computer use. Almost every job could not be separated from the use of computers. Based on data from World Health Organization (WHO) in 2014, the incidence of asthenopia (eye fatigue) ranged from 40% to 90%. This research aimed to determine the relationship between symptoms of Computer Vision Syndrome and Visual Display Terminal utilization. Methods: This research was a quantitative with analytic survey method. Based on the data collection method, this research included as observational research type. This research was conducted with cross-sectional study design. Data collection was carried out with doctor's diagnosis guidelines, interviews, measurement using questionnaires, and observation. The population was 47 permanent workers and the sample taken was 42 respondents from the design division workers. The sampling technique used simple random sampling. The variables in this research were age, working period, distance to VDT, and general lighting intensity. Results: This research showed that the factors associated with symptoms of Computer Vision Syndrome were working period and eye distance to VDT. Conclusion: The longer the working period and the more distance between the eye and the VDT, the more symptoms of VDT would be.Keywords: computer use, symptoms of computer vision syndrome, visual display terminal

Introduction: All works have the potential to cause work fatigue, one of which is in the dome installation work. Work fatigue leads to decreased work capacity and endurance to work. Factors causing work fatigue are age, sex, nutritional status, smoking habits, history of illness, work environment, workload, work hours, and rest periods. This study aims to find out the correlation between age, nutritional status, and smoking habits with work fatigue in dome installation workers at PT. A. Methods: This type of research was an observational analytic research using a cross-sectional approach. This study had a population of all employees of PT. A in the dome installation section. The samples used were 33 workers, taken using total sampling. This study was conducted in 2020. This study used variables of age, nutritional status, smoking habits, and work fatigue. Instrument for collecting data was a questionnaire. The Industrial Fatigue Research Committee (IFRC) questionnaire was specifically used to collect data on work fatigue. In addition, data on nutritional status were obtained from the calculation of Body Mass Index (BMI). The contingency coefficient was used to analyze the data. Results: Theworkers mostly (81.8%) experienced mild work fatigue and were aged ≤ 35 years, had normal nutritional status, and were mild smokers. Conclusion: There was a weak relationship between age and nutritional status with work fatigue and a veryweak relationship between smoking habits with work fatigue. Keywords: age, nutritional status, smoking habits, work fatigue
