<![CDATA[Tuberculosis remains a major public health problem worldwide and continues to contribute significantly to morbidity and mortality, particularly in developing countries. Limited public knowledge regarding tuberculosis transmission and prevention often leads to delayed diagnosis and inadequate preventive practices within communities. Health education provided by nurses is considered an important strategy to improve community awareness and promote preventive behaviors against tuberculosis. This study aimed to determine the effect of a health education intervention on community knowledge regarding tuberculosis prevention in Tanak Beak Village, within the working area of UPT Puskesmas Narmada. This study used a pre-experimental design with a one-group pretest–posttest approach. The participants consisted of 30 community members selected using purposive sampling techniques. Data were collected using a structured questionnaire that measured knowledge of tuberculosis prevention before and after the health education intervention. The educational session was delivered by nurses using lectures, discussions, and visual educational media. Data analysis was conducted using descriptive statistics and a paired sample t-test to determine differences in knowledge scores before and after the intervention. The results showed that the mean knowledge score before the intervention was 56.3, indicating a moderate level of knowledge among respondents, while after the health education intervention the mean score increased to 82.7, reflecting a substantial improvement in community understanding of tuberculosis prevention. Statistical analysis demonstrated a significant difference between pretest and posttest scores (p < 0.05), indicating that the intervention was effective in increasing knowledge levels. In conclusion, nurse-led health education interventions play an important role in strengthening community knowledge and awareness related to tuberculosis prevention. Continuous community-based health promotion programs are recommended to support tuberculosis control efforts and reduce disease transmission.]]>
