The aim of this community service is to provide preventive education based on the CERIA application in preventing anemia for young women at SMK X. The method used is the CERIA application from the Ministry of Health. The population is 21 female students consisting of representatives from each class X, XI, XII and members of the OSIS of SMK with a mean of 79.13. This means that female students experienced an increase in scores on knowledge about anemia. The results of the analysis showed that there was an increase in scores before and after being given the intervention, namely the socialization of anemia prevention in young women based on the CERIA application. It is hoped that this program will be able to prevent and manage adolescent girls who experience anemia so that the health status of adolescents can improve.
