Abstract The high rate of stunting in Garut Regency has prompted the local government to engage in cross-sector collaboration as mandated by Presidential Regulation Number 72 of 2021 concerning the Acceleration of Stunting Reduction. However, the stunting rate in Garut Regency has increased again in 2023. This study aims to analyze the stages of collaborative governance in the process of collaboration in handling stunting in Garut Regency. The method used is qualitative with a case study type, with data collection through documentation and interviews, using purposive informant selection techniques. The theory used is Morse and Stephens' (2012) collaborative governance, which consists of four stages: assessment, initiation, deliberation, and implementation. The results of the study show that the collaboration process has not been optimal, with various obstacles at each stage, such as stakeholder incompatibility, limited resources, lack of basic collaboration rules, and obstacles in governance and program sustainability. These findings provide recommendations for improving collaboration governance so that efforts to reduce stunting can be more effective and sustainable.
