Ergonomic risk analysis with environmental interventions to reduce occupational diseases

Most small industries still rely on human labour as workers. The use of human labour requires special attention with regard to the risk of occupational diseases. Risks at work can arise from human, environmental and external factors. It has been observed that some manual jobs require energy beyond the worker's capabilities, a working environment that is not conducive and uncomfortable work equipment. Discomfort at work can cause workers to tire quickly. The risks associated with these working conditions can lead to long-term health problems. The aim of this research is to identify the human factors and work environment factors that can lead to occupational health risks. The approach used in this research is the ergonomic risk influenced by work environment factors to reduce the level of fatigue at work. The method used is REBA to identify postures that are not ergonomic due to the work environment and heart rate measurement to assess the level of worker fatigue. The research results show that the F-value < F-table is 1.23 < 3.478, which means that there is a significant relationship between temperature, noise, humidity and lighting on the level of fatigue experienced by workers. The Pearson correlation test confirmed a positive relationship between REBA scores and heart rate, showing that the worse the posture, the higher the level of physical fatigue experienced by workers.
