Abstract

In processing gambier farmers work with various postures, namely standing, sitting, and some in a bent position. This study aims to determine the work posture to assess the ergonomic risk level in gambier processing farmers. This study is an observational study using the Rapid Entire Body Assessment (REBA) method. The survey was conducted in March – July 2022 on gambier processing farmers in Pesisir Selatan Regency, West Sumatra. Work postures were assessed starting from picking gambier leaves, preparing for boiling, boiling, pressing, settling, draining, and printing gambier. There are 11 work postures that were assessed. Data were collected using observations, documentation, and REBA worksheets. Then the data were analyzed based on the score from the REBA table, and the risk score was calculated. The results of the ergonomic risk assessment at each stage of the gambier processing process are it is known that in the process of picking gambier leaves the final score is 10, in the boiling preparation stage there are 4 different work positions with 2 final scores of 6, and 2 final scores 8, then the boiling stage the score final 9, tying gambier leaves for press preparation with a final score of 9, gambier leaf counting with a score of 9, gambier leaf press process with a final score of 9, gambier sap draining process with a final score of 10 and printing process with a final score of 8. Out of 11 postures at the gambier processing stage, nine poses have high risk with a score of 8 to 10, and two positions are of moderate risk. Efforts need to be made to improve equipment for processing gambier to prevent work-related injuries and reduce the physical workload on gambier processing farmers.

Abstract

Refill Drinking Water Depot workers rely on physical strength to work, so they are at risk of experiencing Musculoskeletal Disorders (MSDs) complaints. Based on the initial survey, 13 out of 15 workers (86.7%) experienced MSDs. This research aims to determine the relationship between individual and work factors and MSD complaints among refill drinking water depot workers in Padang City. The study used a cross-sectional design. We collected data from November 2022 to July 2023 with a sample of 83 people, selected using proportional random sampling techniques. The dependent variable in this study is complaints of Musculoskeletal Disorders (high risk if NBM score > 20). The independent variables are age (at risk ³ 35 years), work period (at risk ³ five years), smoking habits (at risk if IB values ³ 200), Working posture (at stake if REBA score ³ 7), physical workload (at risk if ³ 100 beats/minute) and BMI (at risk if < 17 and > 25). Data analysis uses univariate and bivariate analysis (chi-square test). The results of the study showed that 71.1% of workers experienced MSD complaints, 34.9% of workers with a risky age, 19.3% of workers with a problematic work period, 32.5% of workers had a smoking habit, 9.6% of workers with a risky BMI, all workers are not at risk of physical workload and 56.6% of workers work with dangerous work postures. The bivariate test results showed that there was no significant relationship between the variables age (p=0.954), years of service (p=0.192), smoking habits (p=0.233), BMI (p=0.330), and work posture (p=0.499) with complaints of MSD. There was no relationship between age, length of service, smoking habits, BMI, and work posture with MSD complaints. We recommended that business owners collaborate with the Community Health Center to provide education about ergonomics when working for refill drinking water depot workers.

Abstract

Pneumonia remains one of the leading causes of mortality among children under five in Indonesia. Air pollution and climatic factors may increase the risk of pneumonia in this vulnerable population. This study aimed to examine the associations between air pollution, climatic factors, and pneumonia incidence among children under five in Padang City during 2023–2024. An ecological study was conducted using secondary data collected within a 5-km radius of an Air Quality Monitoring Station (AQMS). Air Quality Index (AQI) data were obtained from the West Sumatra Environmental Agency, while daily pneumonia surveillance data were obtained from the Padang City Health Office. Data were analyzed using simple linear regression, multiple linear regression, and descriptive spatial analysis. In the adjusted multiple regression model, carbon monoxide (CO) (β = 0.00, p = 0.027) and ozone (O₃) (β = 0.28, p = 0.039) were positively associated with pneumonia incidence, with O₃ identified as the strongest predictor. In unadjusted analyses, each 1 µg/Nm³ increase in CO and O₃ concentrations was associated with increases of 0.01 and 0.43 daily pneumonia cases, respectively. Together, both pollutants explained 27% of the variation in pneumonia incidence (R² = 0.27). Spatial analysis showed that areas with higher CO and O₃ concentrations tended to have higher pneumonia incidence. Strengthening air pollution control and targeted public health interventions are essential to reduce the burden of childhood pneumonia.
