Background: Workers who undertake occupations that require bending, climbing, crawling, reaching, twisting, excessive activity, or repeated movements may suffer from musculoskeletal disorders (MSDs). MSDs can be prevented by doing Workplace Stretching Exercise (WSE) which is useful for minimizing the risk of musculoskeletal injury, fatigue reduction, muscle balance, and posture improvement, and muscle coordination improvement. Purpose: To analyze the difference before and after giving WSE to the reduction of MSDs complaints. Method: This research takes a quantitative approach, utilizing a quasi-experimental design in one group before and after WSE administration. Total sampling is used for sampling. The respondents of this study were 34 workers in the production division of PT Crown Pratama in 2021. The T-paired test was utilized as a statistical test in this study. Result: The results of the univariate test mean MSDs complaints before and after WSE administration were 42.97 and 36.29. Conclusion: The bivariate test revealed differences in complaints of Musculoskeletal Disorders (MSDs) before and after workplace stretching exercise.

Type 2 diabetes mellitus is the most common type of diabetes accounting for 90% of all diabetes in the world is type 2 diabetes mellitus. Indonesia is ranked 7th out of 10 countries in the world. From health service data, the prevalence of people with type 2 diabetes mellitus has increased with a prevalence of 14.47% in 2019. This study aims to determine the relationship between sex, age, and physical activity with type 2 diabetes mellitus in the elderly at the Balaraja Health Center, Tangerang Regency. Methods This study used a cross sectional design. Sampling for respondent data uses the two-proportion difference test formula, and the number of samples obtained is 189 respondents. The sampling method used was random sampling with a systematic random sampling technique. The results showed that 76.2% did not suffer from type 2 diabetes mellitus, female 56.1%, elderly (60+ years) 66.7%, and high physical activity 89.9%. Based on the bivariate analysis using the chi-square test, there was a relationship between sex (p = 0.012) and age (p = 0.046) with type 2 diabetes mellitus, and there was no relationship between physical activity (p = 1000) and type 2 diabetes mellitus. This study can be concluded that there is a relationship between sex and age with type 2 diabetes mellitus, and there is no relationship between physical activity and type 2 diabetes mellitus. Physical activity is a protective factor against the incidence of type 2 diabetes mellitus.

Background: Based on RISKESDAS data from 2007, 2013, and 2018, the prevalence of injuries in Indonesia had increased from 7.5%, 8.2%, and 9.2% respectively. In 2018, the proportion of injuries ranked 12th place in morbidity in Indonesia with the highest cases in Central Sulawesi Province (13.8%). This study aimed to determine of injury inci­dents in the productive aged groups in Central Sulawesi. Subjects and Method: This was a cross-sectional design conducted in Central Sulawesi from October 2019 to January 2020. A total of 1,323 reproductive-aged household mem­bers was selected by random sampling method. The dependent variable was the incident of injury. The independent variables were age, gender, level of education, employment status, and nutritional status. The data were collected from secondary data of basic health research data in 2018 with household dan individual questionnaires. Bivariate analysis was performed by chi-square method. Results: The bivariate analysis showed that the incidence of injury among the productive aged groups increased with age (OR= 1.50; 95% CI= 1.10 to 2.05; p= 0.021), gender (OR= 1.29; 95% CI= 1.03 to 1.62; p=0.030), level of education (OR= 2.01; 95% CI= 1.14 to 3.56; p= 0.010), employment status (OR= 1.86; 95% CI= 1.19 to 2.90; p= 0.005), and nutritional status (OR= 0.77; 95% CI= 0.55 to 1.07; p= 0.033). Conclusion: The incidence of injury among the productive aged groups increases with age, gender, level of education, employment status, and nutritional status.

Introduction: Sensorineural hearing loss caused by loud noise exposure for a long time is known as the risk ofexperiencing Noise-Induced Hearing Loss. PT. Multi Karya Asia Pacific Raya (PT. MKAPR) is a company that provides products and services to the oil and gas industry in Indonesia. Based on its medical check-up, workshop workers at PT MKAPR have the risk of experiencing Noise-Induced Hearing Loss. The Lodan-9 Workshop area was known to have different noise levels, 88-91 dB in the fabrication, pump and engineering areas, and 90-102 dB in the function test area. The purpose of this study was to identify predicting factors of Noise-Induced Hearing Loss at PT. MKAPR. Method: This study used a case-control design. The population in this study were 26 cases and 48 control. Sample size in this study consisted of 26 cases and 26 control. We used a purposive technique sampling. Data were collected through questionnaire, and then were analyzed by using Chi-Square Test. Result: There were association between noise intensity (P-value: 0.035 OR: 4.714; 95% CI: 1.266-17.561), and work period (P-value: 0.029; OR 5.622; 95% CI: 1.342-23.55) with the incidence of Noise-Induced Hearing Loss. Meanwhile age of workers (P-value: 1; OR: 1.547; 95% CI: 0.336-2.976) and smoking habits (P-value: 0.465; OR: 0.435; 95% CI: 0.096-1.168) have no relationship with the incidence of Noise-Induced Hearing Loss. Conclusion: Noise intensity and work period were predictors of Noise-Induced Hearing Loss on PT.MKAPR’ workers. The longer the workers work in high noise intensity area, the more they are at risk of experiencing Noise-Induced Hearing Loss.Keywords: ear, noise-induced hearing loss, noise, noise intensity
