Low Back Pain (LBP) is pain in the waist or lower spine that can be felt up to the buttocks and thighs. Many workers experience illness. Results The study was conducted on 9,482 workers in 12 regencies and cities in Indonesia, the disease experienced by workers was Musculoskeletal Disorder as much as 16% including Low Back Pain. This study aims to determine the relationship between work duration and work posture with complaints of Low Back Pain at Nagari Simpang Kapuak tailors, Lima Puluh Kota Regency. This research is quantitative with a cross sectional approach. Collecting data through a census of 43 tailors with interviews and questionnaires. Data analysis with univariate, bivariate and Chi-Square statistical test. The results of the study found that 58.1% of tailors experienced severe complaints of low back pain. 72.1% are classified as risky age, 74.1% are female, 58.1% have a BMI at risk, 67.4% work with risky work duration, 69.8% work with risky work postures. There is a relationship between age (p = 0.017), BMI (p = 0.013), work duration (p = 0.002), and body posture (p = 0.006) with complaints of Low Back Pain. To reduce the risk of Low Back Pain, tailors should relax and rest by stretching muscles, exercising based on the age of the worker, consuming foods that contain calcium, working with a balanced working time and doing an ergonomic work system.

Car painting work is one of the jobs that are at great risk of impaired lung function. Paint particles consist of hazardous chemicals such as cadmium, chromium, plumbum, mercury, acrylic resin, isocyanate, and toluene solvents. These materials when proven to enter the respiratory tract can cause lung function disorders. The purpose of this study is to identify hazards, analyze dose-response, analyze exposure and analyze the risk characterization of pollutants. This research is descriptive by analyzing environmental health risks to pollutants around the work environment. The population is all sanding, picking, and painting workers totaling 21 people which become sample. The instruments used in this study were low volume air sampler (LVAS), thermo hygrometers, anemometers, scales, and checklists for observing activity patterns. Data analysis uses stages in environmental risk analysis. Respondents smoke at work as much as 47.6%, and do not use APD 71.4%. Pollutants that exceed the quality standard are dust (0.1538 μg / m3), and Cd (0.0025 μg / m3). RQ value (life time) > 1 for all exposure materials, which means that agent risk is not safe after 30 years of work. Management needs to manage risks such as reducing concentration, exposure time, and frequency of exposure to safe limits by managing risk through a technological approach, socioeconomic approach, and an institutional approach.
