Abstract Benzene is one of the components contained in the glue which is used in shoe-making process of home industry activities. The using of Benzene in a long period can cause hematologic disorders. The exposure of benzene in the working environment of the shoemaker is related to the individual characteristics and the conditions of the working environment. The level of trans, trans muconic acid (tt-MA) in the urine is a manifestation of a research subject's exposure to benzene exposure in the workplace. The purpose of this study was to analyze factors related to urine tt-MA levels of shoemaker. This study was an observational research, and the design of study is a cross-sectional research with 20 people as the research subjects. The independent variables were age, gender, nutritional status, working hours (hour/day), working periods (year) and smoking habit, whereas the dependent variable was urine tt-MA levels. The mean of benzene level in the air is 0.5111 ppm and the mean of urine tt-MA levels is 555, 65 μg/g creatinine. Pearson correlation test indicated that there is a significant relationship between the working hours (hour/day) with the urine tt-MA levels of the research subjects (p= 0.040). Continuous counseling needs to be carried out considering the risks of chemical substances in the home industry of shoes. In addition, the application of the regulation of 5R principles in the workplace is necessary, and maintaining personal hygiene and expanding ventilation as well as providing plantation to reduce the benzene vapor in the working environment of the shoemaker is important.
