BACKGROUND: Anemia is mainly characterized by a lack of red blood cells. Although postpartum anemia is significant, it is rarely detected and studied as anemia among pregnant women. Postpartum mothers physically need to be ready to take care of their newborns, and the normal hemoglobin level needs to be considered to support their activity after delivery. An effort to improve the hemoglobin (Hb) level is by consuming date palm syrup. The study revealed that it could increase hemoglobin levels. AIM: The purpose of the study was to analyze the effect of date palm syrup on Hb levels in postpartum mothers. METHODS: The population of this study was all postpartum mothers who came to midwifery independent practices in Bengkulu City; those who met the inclusion criteria were involved as subjects in this study. This research method was quantitative using a quasi-experimental research design. This study used a two-group pre-test–post-test design to check hemoglobin levels before and after the intervention of date syrup of 10 ml/8 h for 10 days. RESULTS: The result showed date syrup’s effectiveness in increasing hemoglobin levels in postpartum mothers in Bengkulu City; p-value was 0.000 or p < 0.005. CONCLUSION: The results of this study are expected to be used as one of the non-pharmacological therapies given by health workers to increase hemoglobin levels in postpartum mothers.
