Title: Study on Some Future Scenarios of Jakarta Megacity’s (Jabodetabek) Urban Expansion and Beyond: A West Jawa Conurbation Scenarios and Its Potential Impacts


The rapid urbanization in Asian developing countries over the past half century seems to have been followed by excessive of the urban population concentration in very large urban agglomerations which so called as megacities. The growth of megacities in Asia has led to various global problems and requires attention from global communities. Jakarta megacity has grown to become the second largest megacity in the world after Tokyo Megacity (RIHN, 2014). Jakarta as well as other Asian megacities is still experiencing continuous growth and facing various problems that have not been obtained by other major cities in the world. One form of the urban expansion of Jakarta Megacity is the ongoing expansion along the main transport route linking Jakarta to the metropolitan Bandung within 120 km from Jakarta. The objectives of this study were to describe (1) the tendency of urban physical expansion, as indicated by the land use/cover changes over the past 30 years, (2) the tendency of changes in the number and density of population along the Jakarta-Bandung corridor, and (3) describe the potential impacts of the Jakarta-Bandung conurbations. Spatial analysis is made by employing GIS (Geographic Information System) and using remote sensing data. GWR Analysis (Geographically Weighted Regression) is then used to determine the factors that cause the Jakarta-Bandung conurbations. The conurbation of Jakarta-Bandung accelerated after Cipularang highway road linking both cities and has shortened the travel time between them. Conurbations take place due to the tendency the establishment of the settlements and industrial estates built by the private sectors along the corridors. The population of the district and sub-districts along the corridor has grown much faster than population growth at the core of Jakarta megacity as well as the core of Bandung metropolitan. We identified four factors led to urban expansion in this region, namely: (1) government policy, (2) Private-led settlements and new towns, (3) private-manufacturing sector, and (4) infrastructure development. Some of the possible impact of this ongoing conurbation is the rice paddy land conversion, declining of biodiversity and in particular due to the declining of forest and agroforestry areas, congestion and air pollution caused by the increase of vehicle uses. Sustainability of megacities or mega urban regions should at least emphasized on the spatial structure and land use policies, transportation system, disaster hazard, resource consumption rate and governance.
