Abstract

Teenager period is the most critical for development at a later stage in life. Many changes occur in individuals both physically and psychologically. Anemia is defined as a hemoglobin level of less than 12.0 gram/100 ml. In 2018, the prevalence of anemia in Indonesia was 21.7% with anemia patients aged 5-14 years at 26.4% while anemia patients aged 15-24 years was 18.4%. The purpose of this study was to determine the effect of giving green bean juice on hemoglobin levels on the eighth grade students of Jogonalan 1 Junior High School. The research method used was quantitative, pre-experimental designs (Non-designs) with pretest-posttest with control group. The population was all eighth grade students of Jogonalan 1 Junior High School, namely 138 students. The sample used in this study was 24 students consisting of 12 case groups and 12 control groups. The results showed that green bean juice was effective for increasing hemoglobin levels with a p value of 0,000 (p˂0.05). The conclusion is green bean juice is effective for increasing hemoglobin levels. It is suggested that the school can work together with the canteen in providing green bean juice in order to prepare a generation that is not anemic.
