Resilience and Green Infrastructure Environmental Road Design and Disaster-Responsive Drainage in the Paser Urban Area According to Circular Letter of the Director General of Human Settlements 30/2020

Abstract; The sustainable improvement of slum settlements is crucial, aligning with Minister of PUPR Regulation No. 2/PRT/M/2016. The settlement in Desa Muser, Muara Samu District, Paser Regency, East Kalimantan, designated as a slum by Paser Regent Decree No. 653/KEP-116/2021, faces extreme vulnerability to disasters, notably major floods with a distinct 5-year cycle. This risk is exacerbated by inadequate environmental roads and conventional drainage systems. This study aims to analyze the integration of Resilience and Green Infrastructure (GI) principles into the design of basic infrastructure within this specific area. The analysis is guided by the technical provisions outlined in the Director General of Cipta Karya Circular Letter No. 30/SE/DC/2020 (RP2KPKPK guidelines). The Resilience approach focuses on enhancing the settlement's capacity to swiftly recover from recurring flooding, while GI offers sustainable, nature-based solutions for managing water flow and reducing risks. The findings indicate that the environmental road design must prioritize emergency accessibility (supporting fire mitigation efforts) and utilize permeable paving materials to minimize surface runoff. Concurrently, the drainage system requires a shift from conventional structures to GI solutions, specifically integrating biopores and rain gardens. These nature-based elements are essential for localized rainwater harvesting and infiltration, effectively anticipating and managing the high-volume discharge associated with the 5-year flood events. The adoption of Resilience and GI design principles ensures compliance with regulatory standards for physical quality improvement while fundamentally enhancing the long-term resistance and adaptability of Desa Muser settlements against severe hydrometeorological disasters. This approach provides a robust framework for sustainable slum management in East Kalimantan’s urban context.
