Air pollution has become a global problem that cause mortality. Jakarta, the capital city of Indonesia has failed to meet the annual PM2.5 standard of 15 ?g/m3 , wherein East Jakarta specifically has the highest concentration of PM2.5 among the other administrative cities, with an average annual concentration of 49.69 ?g/m3. This study focuses on the knowledge and the perception of the public residing in East Jakarta regarding the health risks of air pollution, and the response preventive behavior. The perception is analyzed by applying the Health Belief Model. A qualitative method is chosen with an online questionnaire as the research instrument. Air pollution data from AQMS, Passive Sampler, and Low-Cost Sensor are used as an additional tool to analyze the perception and behavior based on the respondent’s subdistrict wherein the result show no statistically significant difference (p < 0.05) between the respondent’s subdistrict and knowledge, perception, and behavior despite the differences in PM2.5 and NO2 concentration within subdistricts. The multiple linear regression analysis shows that there is a moderately positive relationship between knowledge, perception, and preventive behavior (R = 0.578). The regression model with the independent variables of knowledge and perception is deemed statistically significant (p < 0.05), indicating that these variables collectively have a significant impact on preventive behavior. The most significant variable that shapes the behavior of the respondent is the perceived barrier (? = 0.345 and p < 0.001). From the multiple linear regression test, the gender, age, subdistrict, knowledge, and perception of the respondent accounts for 29% factors affecting preventive behavior related to health risks of air pollution, with perceived barrier, cues to action, and gender being the variables with significant influence.
