Agricultural development in Indonesia had been conducted in a top-down manner since its independence, which has limited its effectiveness due to the gap between the reality faced by the development actors and actors who are involved in the agricultural supply chain. This paper provides evidence of a more participative model design by involving most of the actors in its process. The study was performed in action research by using a co-creation approach, involving actors who contributed their thoughts in designing the most suitable model that can support them in reaching a more sustainable supply chain for coffee agribusiness in Bandung Regency, West Java, Indonesia. The results show that a co-creation approach has managed to improve the performance of the coffee supply chain by the formation of a cooperative, which enhanced coordination among stakeholders. Furthermore, the involvement of farmers provided significant contributions in the design of the model.
