RESPIRATORY HEALTH OF WORKERS EXPOSED TO WOOD DUST IN THE CHIP AND WOOD UNIT OF PULP INDUSTRY PT. X
This study aims to analyze the decline in lung function in workers exposed to wood dust in the chip and wood department unit. The research was conducted in March 2021 at the Pulp Industry of PT. X South Sumatra. Research sample of 100 workers in the Pulp industry of PT. X and 20 sampling points. This study used quantitative methods, with a cross sectional design, multivariate analysis using multiple linear regression analysis. Work area dust measurement with IOM dust sampler, lung function test with spirometer and ATS-DLD-78A questionnaire. Inhalable dust measurement with gravimetric technique, dust concentration measurement using standard method NMAM-0500 from NIOSH. The variables of this study were age, smoking, height, symptoms of respiratory pain, phlegm; spirometry values in three parameters FVC, FEV1, FEV1/FVC. Determination of abnormalities of spirometry values based on Indonesian nomograms. Spirometry measurement results show the highest abnormality in FVC by 13%, FEV 1 by 2% and FEV 1 / FVC by1%. In this study, a predictive model of lung function disorders was obtained: FVC = -0.880 – 0.041Lk + 0.025Tb – 0.034age + 0.335smoking + 0.055cough + 0.098phlegm + 0.113Pd – 0.466Gsp. The variable that has the greatest influence on determining the value of FVC is the smoking variable of 0.207, the assumption of multicolinierity obtained VIF is no more than 10 so that it can be said that there is no multicollinearity in each variable, the assumption is fulfilled. The dust variable as a confounding variable that also affects lung function disorders with a prevalence risk of 1,893. The riskiest job site in the chip and wood department is debarking.
