Distribution Of Slums, Building Configuration, And Land Cover Composition in Banjarmasin City, South Kalimantan Province, Indonesia Using a Geographic Information System
Keywords:Distribution of slums, building configuration, land cover, Banjarmasin City
On This research aims to analyze the distribution of slums, building configuration, and land cover composition in Banjarmasin City, South Kalimantan Province, Indonesia by using a geographic information system. Material and methods: To determine the existing conditions of space utilization for various types of designation, a Geographic Information System (GIS) is used with an overlapping technique (overlay). The map of land utilization used is the 2014-2019 map. Result: In 2019 it is also known that the distribution of slum areas in Banjarmasin City is evenly distributed with the category of light-slum and is divided into 52 locations in 5 Districts. In 2019 it was discovered that all land on the riverbanks has been covered by buildings. The settlement areas in Banjarmasin City continues to grow, in 2014 the area was 3712.28 ha (37.70%) while in 2019 the area was 5182.20 ha (52.63%). The use of water bodies especially swamp, began to decrease due to the expansion of the settlement areas. The use of water bodies in 2014 was 677.73 ha (6.88%), this use was reduced by about 2% in 2019 to 675.53 ha (6.86%). The use of land as dry agricultural land also decreased very drastically. In 2014 the area was 2441.94 ha (24.80%), while in 2019 the area was 911.30 ha (9.26%). Conclusion: The overlay results from land utilization and building configuration are very helpful in formulating policies for spatial planning and slum settlements in Banjarmasin City. Based on the results of the analysis, it is known that the area of settlements is increasing, and it reduces the use of water bodies, especially swamp. This can affect the quality of the river's carrying capacity in terms of its spatial and ecology.
