Landuse And Land Cover Change Of Alluvial Plain Using Geographic Information System And Integration High Resolution Imagery And Google Street View In Sempaja, Samarinda City

Abstract

Rapid urbanization in urban alluvial plains presents significant challenges, including changes in land use and land cover in the Sempaja alluvial plain of Samarinda City from 2002 to 2023 have increased flood risk in the area. This study aims to analyze land use and land cover changes and their impact on flood risk using Geographic Information Systems (GIS) and the integration of high-resolution imagery with Google Street View. Data were obtained from high-resolution satellite imagery (2002, 2013) by google earth pro and the 2023 photo map by the Ministry of Agrarian Affairs and Spatial Planning/National Land Agency of the Republic of Indonesia (ATR/BPN) which were then processed and analyzed using ArcGIS 10.8 software. GIS analysis revealed an increase in built-up areas from 30.6 hectares (14%) in 2002 to 73 hectares (34%) in 2023. The findings also show a decrease in the area of natural wetlands and rice fields converted into residential and commercial zones, leading to increased surface runoff and flood risk. The construction of stilt houses around the Karang Mumus River represents an effective adaptive strategy to local hydrological conditions. This study highlights the need for sustainable urban planning and improved flood management, including wetland preservation, green infrastructure creation, and adequate drainage systems. The implications of this research emphasize the importance of integrating various building types in urban planning to enhance flood resilience.
