Abstract

Cities develop as activity centers because they provide more facilities than rural areas.  After being established as the capital of Blitar Regency based on Government Regulation No. 3/2010 dated January 5, 2010, Kanigoro experienced a shift from rural to urban land use followed by an increase in population, causing the quality of the environment to decline, requiring the structuring of sustainable urban development from social, economic, and environmental aspects. This study examines the development pattern of urban settlements with an environmental perspective to build an understanding of the spatial growth process that occurs in urbanization and urban formation in a small suburban area. This research uses a quantitative approach from secondary data analysis. Initial identification of the urban regions using Arc GIS to analyze land use conditions, especially settlements, using secondary data images in 2022 to obtain land use and settlement area maps in 2022. Kanigoro Urban Settlement area develops following grid and linear patterns, following road access and service trade. The thick rural-urban mix is primarily agricultural and residential. The ecological approach of Kanigoro Urban tends to be differentiated; the population lives scattered in convenient areas that are easy to reach, and spatial expression is fragmented, including "bridgeheads" prioritized settlements near the city center, learning centrifugal style, urban functions from inside the city to the outside. Based on the land use and spatial pattern of settlement distribution, Kanigoro Urban is proposed to use the stellar/radial city model. Keywords: Land Use, Sustainability, Urban Settlements

Abstract

Rapid land use change due to population growth and urbanization presents significant challenges to urban development. This study aims to map the groundwater level and water infiltration conditions in residential areas and investigate the conditions in the Kanigoro Urban Area. This research identifies a spatial approach to analyze satellite image maps with ARC GIS software for land cover changes that overlap with slope maps, soil types, rainfall, groundwater basins, groundwater flow patterns, and spatial pattern plan maps to obtain water infiltration conditions and building distribution. The analysis showed that water infiltration capacity has been reduced due to converting open land into built-up areas, resulting in decreased groundwater quality and quantity and an increased risk of flooding.  Based on water infiltration capacity and potential environmental impacts, this map recommends the best locations for settlement development. The results show that the water infiltration condition of most settlement areas in the Kanigoro Urban Area is critical or rather critical. Therefore, efforts must be made to increase water infiltration capacity by implementing sustainable drainage systems, developing green open spaces, and utilizing environmentally friendly technologies. This research produced a settlement direction map based on the analysis of water catchment conditions and groundwater levels that can be used by local governments when they make better and more sustainable spatial plans.
