<![CDATA[Pulmonary tuberculosis remains a global health problem with a significant burden, particularly in densely populated areas such as Jakarta. The occurrence of this disease is influenced not only by medical factors but also by the level of individual knowledge and family support in preventing its transmission. This study aims to analyze the relationship between knowledge level and family support with efforts to prevent the transmission of pulmonary tuberculosis in the working area of the Kemayoran Public Health Center, Central Jakarta. This study employed a quantitative approach with a cross-sectional design involving 75 respondents selected through a survey technique using a structured questionnaire. Data analysis was conducted using univariate analysis to describe variable distributions and bivariate analysis using Spearman’s rho correlation test. The results showed a significant relationship between knowledge level and efforts to prevent the transmission of pulmonary tuberculosis, with a strong correlation. In addition, family support also demonstrated a very strong and significant relationship with prevention efforts. The majority of respondents had a moderate level of knowledge, tended to have low family support, and their prevention efforts were generally in the moderate to good category. In conclusion, this study highlights that improving knowledge and strengthening family support play an important role in enhancing preventive behaviors against pulmonary tuberculosis transmission. Therefore, continuous health education interventions and family empowerment are needed to reduce the transmission rate of pulmonary tuberculosis, particularly in urban areas.]]>
