The research design was a pre-post test with a control group design and quasi-experimental design. The research design used in this research is "Control Group Design". In this study, there were two groups, namely the intervention group using the Emo Demo video method and the control group using e-leaflets. Results. Emo Demo video promotion has a positive effect on knowledge (p value 0.000), attitudes (p value 0.000), and behavior (p value 0.000) in adolescent girls to prevent anemia compared to e-leaflets. Conclusion. Emo Demo video as a learning media is more effective in increasing knowledge, attitudes, and behavior in choosing foods high in iron in adolescent girls than in the group using e-leaflets. It is important to provide continuous Emo Demo videos and do the monitoring of adolescent girls to prevent anemia.
