Purpose: The printing industry has been one of growing industries currently. The printing industry in Indonesia in 2011 is estimated to reach 4.7 percent or higher than the world average growth which is only 1.6 percent. This means that the production and printing services needs in Indonesia are greatly increased. Industrial processes that use labor, especially those related to using chemicals in the production process, will be at high risk of potential hazards. According to the Ministry of Industry and Trade, there are already 45 industries that use hazardous materials, one of which is the printing industry. The purpose of this study is to analyze exposure to toluene through hippuric acid levels in the urine of printing industry workers.

Method: This research is a quantitative observational analytic study using a cross sectional design conducted from March to July 2018. The sample of this study is 50 respondents located in 6 printing industries in Medan City.Most of the respondents are males, which is 38 people (76%).

Results: The amount of toluene exposure in ambient air at 6 printing averages of 6.97 ppm is much lower than the NAB value of 50 ppm, and the average hippuric acid level of printing employees is 143.5 mg / g creatinine which is far from normal NAB hippuric acid level (1600 mg / g creatinine). Statistical test results shows that there is a correlation between sex with levels of hippuric acid with p = 0.046 (p <0.05).

Conslusion: is strongly suggested for the owner of every printing industry to monitor the health of their employees periodically. The Health Ministry also needs to specifically regulate the protection of labor from toluen. To reduce toluen exposure, it is recommended that the owners of printing industries equip their employees with PPE (Personal Protective Equipment) and to manage better office hour, day off, and furlough
