INTRODUCTION
Adolescents are a period of transition to adulthood. During this period there were many changes in adolescents, physically, psychologically, and psychosocial (Laura, 2012;Sofia & Adiyanti, 2014;Firdaus et al., 2018).

Menstrual conditions can increase the risk of anemia (Basith et al., 2017). Young women will experience lethargy, dizziness, and pale faces when they are anemic. This resulted in a decrease in their concentration and motivation to learn (Indartanti & Kartini,
