Application of the spatial model of road trace development in the swamp area of Banyuasin District

Planning for road network development in swampy areas is inseparable from determining road trace to obtain a suitable road network layout.  The suitability of geological, topographic, soil, hydrological and land use conditions is a matter that must be considered, coupled with other issues such as land value, land ownership, social and economic impacts, and identification of environmentally sensitive areas. There are nine components that are considered in determining road trace in swamp areas in order to obtain environmentally sound road construction, namely: soil texture, puddle, CBR value, peat soil, land use, average daily traffic, tonnage, accessibility, and sociogeography.  This study aims to obtain a road trace in an environmentally friendly swamp area using a road trace model in swamp areas developed by Indrayani, et al in 2019. The application was carried out in the swamp area of Banyuasin district, South Sumatra province, by taking the 9 components in the recommendation. The method used in this research is remote sensing in the introduction of the physical environment, while the scoring and weighting methods use multicriteria spatial analysis in determining the suitability of the area..  From the modeling results, it is found that the suitable area for road alignment is 136.66 km2, which is quite suitable for 3151.66 km2, and which is very inappropriate is 39.71 km2. Meanwhile, the road alignment that connects between districts in the study area is obtained in the form of a thematic map.
