Diarrhea is one of the diseases that remains a leading cause of morbidity and mortality among elementary school-aged children. A mother's knowledge as the primary caregiver is an important factor in the prevention of diarrhea. This study aims to analyze the effect of health education through pop-up book media on mothers' knowledge about diarrhea prevention in children at SDN 160 Mulyorejo II, Luwu Utara Regency. The research design used a quantitative quasi-experimental approach with a one group pretest posttest design. The population consisted of 143 mothers with children attending SDN 160 Mulyorejo II, with a sample of 54 respondents selected using stratified random sampling. The intervention was carried out by providing education using pop-up book media, followed by measuring knowledge before and after the intervention using a questionnaire. Data analysis using the Wilcoxon Signed Rank Test yielded p < 0.001, indicating a significant effect of health education through pop-up book media on mothers' knowledge about diarrhea prevention. This media is effective because it combines three-dimensional visual and interactive elements that enhance mothers' interest and understanding of health material. The conclusion is that health education through pop-up book media can significantly improve mothers' knowledge about diarrhea prevention in children, and is recommended as an alternative educational medium in public health promotion.
