The Relationship Between KOLAK PISIN (Lactation Counseling and Oxytocin Massage) and Breast Milk Production in the Kalisat Health Center Working Area

Insufficient breast milk production is a common concern during the early postpartum period and may undermine mothers’ confidence in maintaining exclusive breastfeeding. This study examined the relationship between KOLAK PISIN, an intervention combining lactation counseling and oxytocin massage, and breast milk production among breastfeeding mothers in the Kalisat Health Center working area, Jember, Indonesia. A posttest-only controlled experimental design was used. The study included 20 mothers on postpartum day 10 who met the eligibility criteria; all eligible participants were included by total sampling and were divided into an intervention group (n = 10) and a control group (n = 10). The intervention consisted of structured lactation counseling using a leaflet, discussion and question-and-answer activities, followed by oxytocin massage along both sides of the spine. Breast milk volume was measured with a manual breast pump and measuring cup, and group means were compared using an independent-samples t test after assessment of normality and homogeneity. Mean breast milk production was 703.50 mL/day (SD = 39.019) in the intervention group and 658.50 mL/day (SD = 24.950) in the control group. The mean difference was 45.00 mL/day (95% CI 14.23 to 75.77), with t(18) = 3.073 and p = 0.007. These findings indicate a statistically significant difference in milk production between groups, with higher production in mothers receiving KOLAK PISIN. The combined intervention may offer a practical postpartum support approach that addresses both breastfeeding knowledge and maternal relaxation. Confirmation in larger randomized studies with more standardized milk-volume measurement is needed.
