In Indonesia, the incidence of anemia is still relatively high. The highest anemia was 57.1% in the adolescent age group. The aim of this research is to determine the difference between giving green bean juice and red guava juice on increasing hemoglobin in adolescents. daughter at SMP Negeri 2 Kledung.
