<![CDATA[Blitar Regency recorded a stunting prevalence of 16.1 percent in 2024, remaining above the East Java provincial average of 12.1 percent and lagging 6.6 percentage points behind the adjacent Blitar City despite both regions being subject to identical national regulations. The fundamental problem raised is the intraregional anomaly indicating that the source of variation in stunting reduction performance lies not in national policy formulation but in the dimensions of regional policy content and implementation context. This study aims to identify and analyse the supporting and inhibiting factors for accelerating stunting reduction by separating the two dimensions of Grindle's model. The methodology employed is qualitative with an embedded single-case study design, two contrasting-performance locus villages as sub-units of analysis, and ten informants from regency level to beneficiaries. Data analysis was conducted through the interactive model of Miles, Huberman, and Saldaña with deductive-inductive coding. The findings reveal supporting factors including tiered regulations, village fund flexibility, local leadership commitment, case-per-child coordination, and cadre responsiveness. Inhibiting factors encompass cross-system data fragmentation, non-name-and-address targeting, location-based convergence claims, implementer workload, rigid APBDes revisions, sectoral egoism, stigma, and high family participation costs. The study concludes that regional policy content sets the performance ceiling while the implementation context determines a village's distance from that ceiling. The contribution of this research is providing a basis for separating interventions between policy design improvement and implementation environment strengthening for the Blitar Regency Stunting Reduction Acceleration Team.]]>
