Background:Breast milk (ASI) is the best method of feeding for infants. The coverage of exclusive breastfeeding at the Tapin Utara Health Center is still below the target, which may be due to insufficient breast milk production. Asitri is a compound known to enhance breast milk production, and it is found in turmeric and kencur (aromatic ginger). Objective:To examine the effect of turmeric and kencur herbal medicine (jamu) on increasing breast milk volume in postpartum mothers in the working area of the Tapin Utara Public Health Center. Method:This was an experimental study using a quasi-experimental design with a one-group pre-test and post-test approach. Postpartum mothers were divided into an intervention and a control group.

Regarding the postpartum day, the most common was day three, with 5 respondents (50%) in both groups. Bivariate analysis showed a p-value of 0.000 (<0.05), indicating a significant effect of turmeric and kencur herbal medicine on improving breast milk production in postpartum mothers in the Tapin Utara Health Center working area.
