<![CDATA[Tuberculosis remains a critical global health problem, including in Indonesia, where low health literacy regarding transmission and early symptoms hinders control efforts at the primary health care level. To address this challenge, an innovative health promotion approach using smartphone-based technology through digital educational media was implemented. This study aimed to analyze the effectiveness of utilizing "Sahabat TB" digital educational media in increasing community knowledge about tuberculosis among suspected cases within the operational area of UPT Puskesmas Labuhan Badas Unit 1. A pre-experimental study using a one-group pretest-posttest design was conducted on thirty-three suspected tuberculosis respondents selected via purposive sampling according to specific inclusion criteria. Data on knowledge levels were gathered using structured pretest and posttest questionnaires and analyzed using the non-parametric Wilcoxon Signed-Ranks Test. The results revealed that prior to the intervention, the vast majority of respondents had a poor level of knowledge (97.0%). Following the intervention, respondents' knowledge improved remarkably, with 93.9% achieving a good knowledge level and none remaining in the poor category. Statistical analysis showed a significant improvement in knowledge scores with a Z-value of -5.023 and a p-value of 0.000. In conclusion, the "Sahabat TB" digital educational media is significantly effective in enhancing public knowledge regarding tuberculosis, thereby offering a promising digital health promotion strategy to strengthen disease prevention and early detection in primary care settings.]]>
