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

This study aims to analyze the conversion of paddy fields into residential land and its impact on rice production in Koto Tangah District, Padang City. The research method used was descriptive quantitative by utilizing Landsat 8 satellite imagery from 2013 and 2024, rice production statistical data, and Geographic Information System (GIS) analysis. The research stages included image correction, land use classification, map overlay, calculation of land area changes, and estimation of rice production. The results showed that residential land area increased by 1,169.65 hectares, from 1,966.66 hectares in 2013 to 3,136.31 hectares in 2024. Meanwhile, paddy field area experienced a slight increase of 13.59 hectares, from 1,699.82 hectares to 1,713.41 hectares. The increase in paddy field area contributed to an increase in rice production of 78.82 tons. However, land use changes among villages were uneven, as several areas experienced a decline in paddy field area due to development pressure. The main factors influencing land use change were population growth, residential needs, and land economic value. Therefore, sustainable paddy field protection policies are needed to maintain regional food security
