INTEGRATING CAPACITY-BASED MITIGATION PARADIGMS AND SUSTAINABLE DEVELOPMENT GOALS (SDGs) INTO RESILIENT URBAN SPATIAL PLANNING : A CASE STUDY OF THE NOVEMBER 2025 HYDROMETEOROLOGICAL CRISIS IN LANGSA CITY

Abstract

Langsa City faces escalating challenges from hydrometeorological disasters that threaten socio-economic stability, as evidenced by the extreme flooding event on November 26, 2025. This study aims to formulate an integration model between local spatial planning policies (RDTR/RTRW) and capacity-based disaster mitigation paradigms within the Sustainable Development Goals (SDGs) framework, specifically Goal 13 (Climate Action). Employing a descriptive qualitative method with a spatial approach, this research identifies infrastructure vulnerabilities and socio-economic impacts across five districts. Spatial analysis reveals that rice field land cover in Langsa dropped from 2,410 hectares in 2012 to 1,925 hectares in 2025, representing a significant loss of natural water retention. Analysis of the November 26, 2025, event reveals spatial anomalies where floodwaters encroached into zones previously categorized as "low risk," indicating a systemic dysfunction of infiltration systems due to uncontrolled land conversion. Despite the Qanun RTRW mandate for 30% Green Open Space (RTH), field implementation is hindered by limited indigenous engagement in autonomous mitigation. This article recommends a drainage network engineering strategy integrated with Gampong Social Capital specifically institutional trust in Geuchik and Tuha Peut as a sustainable urban resilience solution. These findings contribute to the global urban resilience literature by emphasizing the empowerment of the smallest community units as a mitigation basis in developing nations.
