To create a comprehensive framework for stakeholder collaboration, this chapter integrates systems thinking, system dynamics, and Service-Dominant Logic (S-D Logic) to analyze Indonesia’s food security issues. According to preliminary research, a lack of cooperation between ministries, local governments, operators, and communities has resulted in fragmented rules, unreliable data, pricing instability, and misaligned import decisions. In response, the government strengthened multi-sectoral food governance by establishing the National Food Agency (Bapanas) as a high-level regulator. This chapter argues that food security is a complex socio-institutional issue that goes beyond production capacity and requires a holistic approach that captures dynamic interactions, resource exchanges, and institutional alignment. Drawing on service science, this study conceptualizes food security as a value co-creation process that integrates knowledge, capabilities, and resources to achieve shared outcomes across various actors. System dynamics is applied to model stakeholder interactions through Causal Loop Diagrams (CLDs), which depict reinforcing and balancing feedback loops that influence willingness to collaborate, perceived benefits, institutional vision alignment, and conflicts of interest. The resulting conceptual simulation highlights leverage points for enhancing collaboration and improving policy coherence. Overall, this chapter proposes a collaboration-oriented systemic model that positions Bapanas at a strategic point, enabling adaptive governance, specifically as a regulator of Indonesia’s food ecosystem.
