Abstract

This study aims to analyze the suitability of residential land using a Geographic Information System (GIS) in Koto Tangah District, Padang City, and to compare it with the Regional Spatial Planning (RTRW). The research method used was descriptive quantitative with spatial analysis techniques through scoring, weighting, and overlay of several parameters, namely slope gradient, rainfall, soil type, land movement, and distance to main roads. The research data were obtained from various secondary sources such as Ina Geoportal, CHIRPS, and PVMBG. The results showed that most areas of Koto Tangah District have moderate to high land suitability levels for residential development, especially in lowland areas with good accessibility. Areas that are less suitable are generally located on steep slopes, prone to land movement, and have high rainfall intensity. The comparison with the RTRW indicates that most residential areas are in accordance with the spatial planning directives, although there are still several areas that require land use control to achieve sustainable development.

Abstract

Determining the priority scale for handling inundation or flooding in Koto Tangah District is very important to optimize the use of resources, minimize social and economic impacts, and improve the effectiveness of mitigation measures. This study aims to (1) determine the extent of the area affected by flooding in Koto Tangah District, Padang City; and (2) determine the priority scale for flood management in Koto Tangah District, Padang City. The data processing method used to determine the extent of flood-affected areas employed the Backscattering Thresholding Algorithm obtained from Google Earth Engine (GEE), utilizing ArcMap 10.8 software for flood area calculation. To determine the priority scale for flood management, a scoring method and hierarchical quantitative analysis were applied using a Geographic Information System (GIS). Based on the research results, it can be concluded that the flood-affected area in Koto Tangah District covered 9.92 km², with two villages having the largest flood impacts, namely Dadok Tunggul Hitam Village and Parupuk Tabing Village. The results of determining the flood management priority scale showed that the highest scores were obtained by Batipuh Panjang Village and Lubuk Buaya Village, which were categorized as Priority 1.
