Results: The average knowledge score increased from 65% at baseline to 86% after the intervention, representing an absolute increase of 21 percentage points and a relative improvement of 32.31%, exceeding the predefined success criterion of a ≥20% increase. Conclusion: The program was effective in enhancing Posyandu cadres’ understanding of smoking-related health risks and their ability to perform early hypoxia detection using pulse oximetry.
