The Effect of CO Emissions on Lung Vital Capacity in Vehicle Inspectors at the Transportation Department in Slawi

Carbon monoxide is a colorless and odorless gas that can cause various diseases, one of which is respiratory disease. The quantitative research method used a cross sectional approach and was analytic observational. Measurement of carbon monoxide at PKB Slawi building with an interval of 15 minutes obtained an average CO gas of 89.36 ppm. The analysis used was univariate and bivariate. Test used by Fisher's Exact Test. Of the 20 workers, there were 12 workers who had lung function disorders,and 8 workers have normal lung. Tests obtained a p value of 0.005 <0.05, which means that it has a relationship between exposure to CO emissions and impaired lung function. Meanwhile, for the confounding variable, each variable was obtained for a P value> 0.05 with a significance level of 95 so that Ho was accepted, Ha was rejected which means that theres no relation between the various variable with lung function. © 2025 Institute of Physics Publishing.
