Background: Postpartum contraception is a way to prevent recurrent pregnancies to ensure the health of both mother and baby. Many postpartum mothers think that there will be no pregnancy during amenorrhea in the postpartum period and will use the contraceptive method after the first menstruation. There are still some who do not use contraception. Contraceptive success will be achieved if the counseling and media are effective. Palangka Raya's city has a Bapalas Bidan culture, a ritual in which a newborn baby is declared a midwife's child until the midwife's blessing ceremony is carried out for the baby and the mother.
Methods: This research type is a quasi-experimental study with two group comparison pretest-posttest design with counseling intervention and booklets. The research subjects were postpartum mothers who gave birth or were treated at the Midwives Individual Service in Palangka Raya City, amounting to 30 each per treatment and control group.
Results: There was a difference in the mean and an increase in the group's knowledge score after receiving counseling through the Bapalas Bidan (p = 0.000). The increase in knowledge was higher in the group that received counseling than in those who did not get counseling. Postpartum mothers who have high knowledge of contraception use contraception more than mothers with low knowledge. The proportion of postpartum mothers who used contraception was more in the group who received counseling (p = 0.018), aged 20-35 years (p = 0.015), had parity ≥3 (p = 0.024), and higher education (p = 0.006).
Conclusion: Postpartum mothers who have high knowledge of contraception use contraception more than mothers with low knowledge.
