Spatial demand will increase when the population growth in an area. For sufficient space will occupy the surrounding land (periphery). This condition is known as urban sprawl. Urban sprawl is a complex phenomenon, as it affects social life and becomes a serious environmental problem. Environmental problems that occur because of the change in the land function of agriculture and forests into residential areas and commercial purposes. This study aims to conduct trend analysis of the spatial and temporal dynamics of urban/built-up areas during the periods 1990–2016. Integration of remote sensing, GIS, and Shannon’s entropy statistical approach was used to obtain information regarding dynamics change in the areas. The results of the trend entropy value analysis show that urban/built-up development is tending to spread, with increases in entropy values based on the region’s urban/built-up sub-watershed areas during the 1990–2016 periods of 1.464 and 1.597, respectively. Meanwhile, based on the radial distance from Bandung city, these are 1.511 and 1.737, respectively. The results of the relative entropy are equal to 0.151 in 1990, with an increase to 0.156 in 2016, based on the region’s urban/built-up area of the sub-watershed. Meanwhile, based on the radial distance from Bandung city, the values were 0.156 in 1990 and 0.170 in 2016. This study can be used as important benchmarks for planners, policymakers, and researchers regarding spatial planning in the study area. The results could also provide important inputs for sustainable land use plans and strategies to reduce disasters and flood hazards, as well as flood disaster vulnerability analysis of residential areas.
