Latar Belakang: Kabupaten Aceh Selatan mengalami lonjakan prevalensi stunting dari 27,3% (2021) menjadi 40,2% (2023), melampaui ambang krisis WHO (>20%), dan tetap tinggi pada 34,2% (2024), berlawanan dengan tren nasional yang menurun. Tujuh kecamatan ditetapkan sebagai lokus stunting berdasarkan SK Bupati Nomor 358 Tahun 2023. Tujuan Penelitian: Menganalisis pengaruh multidimensi meliputi enabling determinants (Resources, Norms), underlying determinants (Food, Practices, Services), dan immediate determinants (Diets, Care) terhadap kejadian stunting pada anak usia 24–59 bulan. Metode Penelitian: Penelitian kuantitatif cross-sectional pada 372 responden menggunakan rumus Slovin (error 5%) dan stratified random sampling dari 4.686 anak di posyandu tujuh kecamatan lokus. Data dianalisis menggunakan SEM-PLS (SmartPLS 3.29). Hasil Penelitian: Resources berpengaruh positif signifikan terhadap Norms, Food, Practices, dan Kejadian Stunting. Dari 7 hipotesis langsung ke Kejadian Stunting, hanya Resources, Diets, dan Care yang diterima; sedangkan Food, Practices, Norms, dan Services tidak signifikan. Diets merupakan pengaruh terkuat, diikuti Resources, sementara Norms memiliki pengaruh langsung terlemah. Resources terhadap Practices adalah pengaruh antarkonstruk terkuat, sedangkan Food terhadap Practices terlemah, dengan Norms terhadap Practices satu-satunya hipotesis antarkonstruk yang ditolak. Kesimpulan: Diets dan Resources adalah pengaruh paling dominan terhadap kejadian stunting. Peningkatan asupan gizi anak dan penguatan sumber daya rumah tangga melalui edukasi gizi menjadi strategi intervensi paling efektif di lokus stunting Kabupaten Aceh Selatan.

Background: Aceh Selatan Regency experienced a surge in stunting prevalence from 27.3% (2021) to 40.2% (2023), exceeding the WHO crisis threshold (>20%), and remained high at 34.2% (2024), contrary to the declining national trend. Seven sub-districts were designated as stunting loci based on Regent's Decree No. 358 of 2023. Objective: To analyze the multidimensional influence of enabling determinants (Resources, Norms), underlying determinants (Food, Practices, Services), and immediate determinants (Diets, Care) on stunting incidence in children aged 24–59 months. Methods: A quantitative cross-sectional study involving 372 respondents, determined using the Slovin formula (5% error margin) and stratified random sampling from 4,686 children at posyandu in seven locus sub-districts. Data were analyzed using SEM-PLS (SmartPLS 3.29). Results: Resources significantly and positively influenced Norms, Food, Practices, and Stunting Incidence. Of seven direct hypotheses toward Stunting Incidence, only Resources, Diets, and Care were accepted, while Food, Practices, Norms, and Services were not significant. Diets showed the strongest influence, followed by Resources, while Norms had the weakest direct influence. Resources on Practices was the strongest inter-construct relationship, while Food on Practices was the weakest, with Norms on Practices being the only rejected inter-construct hypothesis. Conclusion: Diets and Resources are the most dominant influences on stunting incidence. Improving children's nutritional intake and strengthening household resources through nutrition education are the most effective intervention strategies in the stunting loci of Aceh Selatan Regency. Keywords: stunting, children aged 24–59 months, enabling determinants, underlying determinants, immediate determinants.
