EFFECT OF COAL DUST EXPOSURE TO THE VALUE OF PEAK EXPIRATORY FLOW COAL MINING WORKERS SOUTH KALIMANTAN

Abstract

Occupational lung disease is a pulmonary disease that occurs due to inhalation of harmful particles, fog, vapors or gases while a person is at work. In Indonesia, occupational lung diseases caused by dust are estimated to be quite numerous, although existing data is still lacking. Dust inhaled by labor can cause abnormalities in lung function or capacity. However, the effect of coal dust exposure on coal mining company workers on the value of the peak expiratory flow (PEF) is not yet known. Studying the effect of coal dust exposure on coal mining company workers on the value of peak expiratory flow. Observational analytical research is carried out cross-sectionally. Data was collected from the results of the examination of the peak flow of respiration of PT. X Satui in September – October 2022. Test using chi-square method and independent t-test. Of the 16 subjects, there were 14 subjects with green PEF results and 2 subjects with yellow PEF results. Mean age 32.38±8.188, BMI 23.8337±3.75252, peak flow meter result 527.5000±91.97826. A total of 14 subjects smoked, 6 had comorbid dyslipidemia, 7 subjects had radiological features of pulmonary emphysema. Analysis of the relationship between PEF and age p=0.166, BMI p=0.917, smoking p=0.568, comorbid p=0.051, radiological features of pulmonary emphysema sign p=0.849. There is no relationship between coal dust exposure to peak expiratory flow.
