Introduction -Indonesia is the third country with the highest prevalence of stunting toddlers in Southeast Asia or South-East Asia Regional (SEAR). Efforts that can be made to prevent stunting in preschool-age children include providing early stimulation. This stimulation can be carried out through early childhood education programs (PAUD). Preschool children can receive a stimulus using audiovisual media. Audiovisual media plays a somewhat important role in providing stimulation because this media can facilitate understanding and strengthen the memory of preschool children. After all, it is fascinating. Purpose -This study aims to determine the effect of providing early childhood education programs to prevent stunting (PAUD-INCASTING) through audiovisual media on improving nutritional status in preschool children. Method -This research used quantitative methods with a quasi-experiment design. The respondents included 39 preschool-aged children divided into intervention and control groups using purposive sampling techniques. The nutritional status was measured using microtoise measuring instruments. The data analysis in this study used a dependent sample t-test and an independent sample t-test. Results -This study found an increase in nutritional status in preschool children after being given intervention in audiovisual media through the PAUD-INCASTING program. The Pearson chi-square showed an influence between the two variables with a value of Z score p = 0.020 and nutritional status p = 0.034. Conclusion: Through audiovisual media, early childhood education program integration prevented stunting (PAUD-INCASTING) and could improve nutritional status in preschool children.

This study aims to develop audio-visual educational media in the Early Childhood Education (PAUD) program to prevent stunting in preschool children. The research design used is Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development or Production, Implementation or Delivery and Evaluations). The results showed that most resonances were male, as many as 11 respondents (55%), and the highest was SMA, as many as ten respondents (50%). There was an increase in total food intake, breakfast, and dinner, while lunch intake did not differ. The results of education with videos show an influence on food intake and handwashing behavior with a p-value <0.05, but there has been no change in the nutritional status of children. In conclusion, the development of audio-visual educational media in the PAUD program can prevent stunting in preschool children with indicators of increasing food intake, PHBS handwashing behavior, and children's nutritional status.   Keywords: Audiovisual, Handwashing Behavior, Nutritional Status, Stunting, Educational Video
