<![CDATA[Breast milk (ASI) is the optimal nutrition for infants compared to formula milk. One key factor in the success of exclusive breastfeeding is Breastfeeding Self-Efficacy (BSE), which can be enhanced through health education. This study aims to determine the impact of health education on exclusive breastfeeding on breastfeeding self-efficacy. The research employed a quasi-experimental design with a nonequivalent (pretest and posttest) control group approach. The sample comprised breastfeeding mothers with infants aged 0 to 2 years, totaling 34 respondents divided into intervention and control groups. Purposive sampling was utilized for sample selection. The instrument employed was the Breastfeeding Self-Efficacy Scale Short Form (BSES-SF). Bivariate analysis was conducted using an independent t-test to examine whether there were differences in breastfeeding self-efficacy between the intervention and control groups. Results showed a significant p-value (0.000) < α (0.05), indicating an influence of exclusive breastfeeding health education on breastfeeding self-efficacy among breastfeeding mothers.
