Analysis of Urban Development Dynamics and Flood Disasters in Samarinda City
Samarinda City as an economic, administrative center and a supporting region for the Capital City of Nusantara, It has experienced very good dynamics in both physical and socio-economic aspects. However, this dynamic development has been accompanied by an increase in the intensity and frequency of flooding disasters. The purpose of this study is to analyze the development of the city of Samarinda and its relationship to the phenomenon of flooding. The research uses the DPSIR (Driving forces-Pressures-States-Impacts-Responses) approach to examine the factors and impacts that will arise with economic, social, infrastructure, information technology, environmental, and disaster indicators. Spatial data analysis is carried out using GIS based on Landsat imagery in the period (2010-2025). The results show that the development of Samarinda City from 2010-2015 was very significant, with a transformation towards urbanization with a spatial pattern resembling an urban-rural mix towards an urban expansion zone pattern. This dynamic shows a shift in the morphology of urban space, with natural land being transformed into built-up space. The development of Samarinda from 2020-2025 indicates a phase of consolidation of built-up areas, where the pattern of urban sprawl is transforming into a regional metropolitan city. Land use change and mining expansion contribute to economic growth but cause the loss of the city's ecological functions, thereby increasing its vulnerability to flooding. Development of Samarinda. The results of the DPSIR analysis indicate that urbanization increases the demand for residential areas 10,158.12 ha (115%), Commercial Area 11941.08 ha (287%) leading to a reduction in forest area of 6,722.04 ha (64%). declining ecological functions, and vulnerability to flooding in the of Samarinda City. The results show that the development of Samarinda City from 2010-2015 was very significant, with a transformation towards urbanization with a spatial pattern resembling an urban-rural mix towards an urban expansion zone pattern.Received: 2026-01-06 Revised: 2026-04-06 Accepted: 2026-07-28 Published: 2026-08-08
