Unmet need for family planning (KB) remains a critical challenge in Indonesia. Padang City, West Sumatra, has consistently recorded unmet need above the national target, reaching 29.6% in Bungus District against a 6.5% target. The Kampung KB programme has been introduced, but its effectiveness remains unclear. Objective: To analyse local government policies for reducing unmet need for family planning in Padang City and identify factors influencing implementation success. Methods: A qualitative descriptive approach was employed, using in-depth interviews, observation, and document analysis with 20 purposively selected informants (4 DP3AP2KB officials, 4 PLKB, 4 health workers, 3 BKKBN representatives, 5 couples with unmet need). Data were analysed using the Miles and Huberman model. Results: Implementation has expanded contraceptive access, strengthened education and behaviour-change communication, empowered field workers, and fostered cross-sector collaboration. Effectiveness is constrained by limited resources, low public knowledge, socio-cultural norms favouring large families, and negative perceptions of contraceptives. Applying Edward III's implementation framework, communication, resources, and bureaucratic structure were largely adequate, but local government disposition was the critical constraint. Five factors driving unmet need were identified: knowledge, attitudes, access to information, religion, and husband's support. Novelty: This study offers a multi-stakeholder qualitative policy analysis integrating perspectives of policy makers, implementers, health workers, and unmet-need couples, applying Edward III's framework to examine the gap between policy design and grassroots delivery within the Kampung KB initiative. Conclusion: Reducing unmet need requires strengthened human resource capacity, equitable service access, optimised IEC, and sustained government-community synergy.
