Abstract
Indonesia has one of the most disaster-prone geographies in the world‚ however local wisdoms on disaster risk are yet to be mainstreamed into the national governance system․ This study investigates to what extent‚ and in what ways‚ local wisdoms are acknowledged‚ translated‚ and utilized in Indonesia's national disaster management system using Institutional Theory and Knowledge Co-production lens․ This study employed qualitative document analysis and semi-structured interviews as a research strategy․ We examined three policy documents for the periods from 2007 to 2029‚ and conducted interviews with 15 respondents at five levels of governance: national agency officials‚ regional administrative practitioners‚ cultural scholars‚ and local community leaders․ It can be said that respect for local wisdom is contained implicitly in Law No․ Both the 24/2007 and the more operationally ambiguous RENAS PB 2025-2029 are referenced in all three documents‚ but neither states how both plans would be appropriated or operationalized together․ Legal gaps in community-based disaster risk reduction‚ and dependency on external funding‚ continue to be challenges․ Regional regulation and institutionalization of Nyadran in Semarang‚ Amma Toa in South Sulawesi‚ and Besiru in East Lombok may be more realistic than national-level regulation․ This study contributes to a theoretical understanding of why local wisdom is not institutionalized in disaster governance and how institutionalization might work‚ drawing on the conceptual framework of Knowledge Co-production․
