Early marriage rates in Indonesia, particularly in West Kalimantan, contribute significantly to the stunting problem. Progress is slow despite a decline from 11.21% in 2018 to 8.06% in 2022. Kapuas Hulu District has the second-highest stunting rate in the province. This research aims to develop a strategic partnership model to control early marriage and prevent stunting in Kapuas Hulu District. The model involves local government, health institutions, NGOs, the private sector, and local communities. Using the Four-Pillar Strategic Partnership Model by (...) Thomas (2012) and Bryson (2013), the study engages stakeholders in planning, organizing, implementing, and monitoring. The local government leads, the private sector provides resources through CSR, the community is empowered in decision-making, and academia offers research support. This integrated approach aims to prevent early marriages and reduce stunting effectively. Based on research and analysis of the Kapuas Hulu District Medium Term Development Plan (RPJMD), it can be concluded that the issue of early marriage or child marriage is not explicitly included or a focus in the regional development planning document. Ease of dispensation is a gap and has the potential to weaken efforts to implement policies to prevent child marriage. The level of public awareness greatly influences the practice of child marriage. The effectiveness of Law Number 16 of 2019 concerning Marriage, especially regarding the implementation of the minimum age limit for marriage, still faces many major challenges. (shrink)
