Multi-actor Collaboration for Stunting Reduction: A community-based Nutrition Education Model

Stunting remains a major public health challenge in Indonesia, particularly in Jeneponto Regency where prevalence remains high. This study develops a Community-Based Nutrition Education Innovation (CBNEI) model through a multi-actor collaborative approach. A mixed-methods design was employed, combining a quantitative survey (N = 100) with qualitative interviews, focus group discussions, and NVivo-assisted analysis. Six variables were examined. The findings show relatively high nutrition attitudes (M = 20.85) but low participation in nutrition-related activities (M = 15.36). Qualitative results identify four central elements: community articipation, cross-sector collaboration, knowledge strengthening, and behavioral support. Key actors include the Public Health Office, PKK, Bappeda, and private CSR institutions. The integration of findings highlights the role of cross-sector coordination, diversified funding sources, and participatory monitoring in ensuring program sustainability. The proposed CBNEI model integrates the CBPAR framework with the Quadruple and Quintuple Helix approaches. The model contributes to the literature on collaborative innovation and offers a practical, replicable framework for stunting reduction in comparable regions.
