Abstract
Aims : The research objective is to determine the safe concentration of non-carcinogenic toluene in Surabaya printing. Methods and Material : The research design used was observational analytic, cross sectional research design with a quantitative approach. The research location is a printing press in Surabaya. Total population was 37 workers, the study sample was taken using the accidental sampling method with a total sample of 30 respondents. The formula for determining the concentration of toluene non carcinogen intake is (CxRxtExfExDt): (Wbx30x365). Results : The concentration value of toluene exposure is greater than the standard set by labor regulations No. 5 of 2018 by 0.2 ppm. A total of 10% of workers falls under normal category, 73% above normal category and 27% below normal category.
