Antimicrobial resistance is an increasingly serious health problem in Indonesia. Based on the Antimicrobial Resistance in Indonesia Study in 2019, 43% of 2,494 respondents showed resistance to several classes of antibiotics. One of the main causes of this issue is the low level of public knowledge regarding the proper use of antibiotics. This condition allows microorganisms to develop and adapt, rendering antibiotics ineffective in treating infections. This study aims to assess the level of knowledge and passive behavior of the community regarding antibiotic use and to analyze the correlation between them in the Cibitung area, specifically Pondok Tanah Mas RT 01 RW 24, Bekasi Regency. The study design is descriptive-analytic observational with a cross-sectional approach. Data were collected in January–March 2025 using a Guttman scale questionnaire from 76 respondents who met the inclusion criteria. The results show that the majority of respondents are aged 36–45 years (24 respondents, 31,6%), female (44 respondents, 58%), and have a senior high school education (60 respondents, 80%). The most commonly used antibiotic is amoxicillin, reported by 42 respondents (55%). The knowledge levels of respondents are categorized as good (22.4%), fair (30,2%), and poor (47.4%). Passive behavior in antibiotic use is also recorded as good (22.4%), fair (30.2%), and poor (47.4%). The chi-square test shows a highly significant correlation between knowledge and passive behavior (p < 0.001). In conclusion, public knowledge and behavior regarding antibiotic use are still relatively low. Continuous education is needed to raise awareness and prevent antimicrobial resistance.
