Subsidence of land levels and rising sea levels are two impacts of climate change that influence human activities, causing tidal floods. 12th and 16th RW (neighbourhood) of Tanjung Mas Subdistrict is a coastal area with a high population density that experiences tidal floods yearly. Structural mitigation programs receive more attention than non-structural programs. The mitigation process requires collaboration between stakeholders to obtain optimal results. This research aims to develop a disaster collaborative governance framework that integrates structural and non-structural mitigation. The research method used is a mixed method with a quantitative primary approach. The results show that collaborative governance in disaster mitigation involves various stages, such as collaborative initiatives, commitment to the process, collaborative processes, and monitoring evaluation. Non-structural mitigation is the primary basis for the success of the disaster management stage, while structural mitigation plays a significant role in the recovery stage. Emphasizing the balance of the role of the hexa helix is needed to create a sustainable mitigation process.
