<![CDATA[Abstrak Penelitian ini bertujuan untuk menganalisis efektivitas kolaborasi lintas sektor dalam pelaksanaan program percepatan penurunan stunting di wilayah perdesaan, dengan studi kasus di Kecamatan Blanakan Kabupaten Subang. Pendekatan penelitian yang digunakan adalah kualitatif deskriptif dengan teknik pengumpulan data berupa wawancara mendalam, observasi, dan dokumentasi. Hasil penelitian menunjukkan bahwa kolaborasi antara UPTD P5A, puskesmas, pemerintah desa, dan kader posyandu belum optimal. Hambatan utama terletak pada lemahnya sistem koordinasi, keterbatasan sumber daya, serta rendahnya partisipasi aktif masyarakat sasaran. Berdasarkan temuan ini, disarankan adanya forum koordinasi rutin lintas sektor, penguatan kapasitas kader dan pelaksana desa, serta integrasi anggaran stunting ke dalam perencanaan Dana Desa. Penelitian ini memberikan kontribusi praktis bagi penguatan tata kelola kolaboratif dalam pelayanan kesehatan masyarakat perdesaan.

The research employs a descriptive qualitative approach, with data collected through in-depth interviews, observations, and documentation. The findings reveal that the collaboration among UPTD P5A, community health centers (puskesmas), village governments, and posyandu cadres has not been optimal. The main obstacles lie in weak coordination systems, limited resources, and low active participation from the target communities. Based on these findings, it is recommended to establish regular cross-sectoral coordination forums, strengthen the capacity of village implementers and cadres, and integrate stunting-related budgeting into Village Fund planning. This study provides practical contributions to strengthening collaborative governance in rural public health services.
