Benzene is a liquid aromatic hydrocarbon compound that is clear, colorless, flammable, and volatile. High concentrations of benzene in the body through inhalation can cause health problems. The purpose of this study is to determine the safe concentration of benzene exposure (C6H6) in Jakarta Kebon Jeruk toll gate keeper. Toll gate keepers are vulnerable to exposure to benzene compounds in the air. 20 toll gate keeper who are divided into toll gate 1 and toll gate 2 were population in the study. The sample technique used total population sampling. The present study used quantitative data analysis manually calculated through the calculation of safe concentration in the environmental toxicology concept. Safe concentration data on Jakarta Kebon Jeruk toll gate keeper were based on data from rat experimental animals, experimental body surface, workers’ characteristics of body weight, body height, body surface area, breathing rate and working duration. In addition, data on benzene concentration, animal km, human km, NOAEL and safe limits for toxin doses were also used. The average measurement results of benzene concentration in the air entering the body of workers through inhalation was 0.00167 mg/m3 (0.0052 ppm). This value is lower than benzene threshold according to the Minister of Manpower Regulation Number 5 of 2018 of 0.5 ppm.6 The safe concentration of benzene calculated was 0.0875 mg/m3 (0.0273 ppm). Based on the calculation of safe concentration, the concentration of benzene in the environment of the Kebon Jeruk toll gate keeper indicated safe.
