Iodine deficiency remains a significant nutritional issue in Indonesia, particularly affecting rural communities with limited access to accurate health information. This research-based community engagement aimed to evaluate the effectiveness of an educational intervention on household knowledge and practices related to iodized salt usage in Bontobakka Hamlet, Jeneponto Regency. The intervention employed a door-to-door campaign using poster media and involved 31 female respondents who were assessed at three time points: pre-intervention, post-intervention, and six months post-intervention. The study utilized a summative evaluative approach based on the CIPP model (Context, Input, Process, Product) to measure program impact. The Friedman test revealed a statistically significant improvement in knowledge levels (p = 0.028), with 87.1% of participants achieving a "good" knowledge score at the final assessment. Integration of religious values through Q.S. Al-Baqarah: 168 enhanced community acceptance, demonstrating the importance of culturally sensitive messaging. The findings underscore the value of combining visual, contextual, and faith-based strategies to promote iodized salt consumption and address Iodine Deficiency Disorders (IDD) in rural Indonesia.
