Urban Spatial Patterns in Banda Aceh City Using the Shannon's Entrophy Model

The rapid development of the city of Banda Aceh occurred in general in the suburbs. The impact is the occurrence of propagation which is a complex urban phenomenon and difficult to measure. Policy makers need a simple method to control and evaluate urban spread. This study integrates the Shannon's Entropy model with remote sensing and GIS to analyze spreading patterns in each sub-district in Banda Aceh City based on two aspects of distance, namely the distance to the city center and the road network to describe urban spreading patterns. The application of the Shannon's Entropy method in Banda Aceh City in 2010-2020 can be seen in the Relative Entropy Matrix which shows that the linear propagation pattern (Quadrant C) is more dominant in Banda Raya District, Baiturrahman District, Kuta Raja District, Kuta Alam District, Lueng District Bata, and the District of Syiah Kuala. Whereas the spreading pattern of Meuraxa District and Jaya Baru District is in quadrant B, namely the elongated (Radial) type of propagation pattern, but in 2020 Jaya Baru District there has been a change in the propagation pattern, namely the linear propagation pattern. In the Ulee Kareng sub-district, there was a pattern of propagation changes in 2020 which was in quadrant D, namely the leapfrog development pattern from the previous year, namely 2010 and 2015 in quadrant C with a linear propagation pattern. The spreading pattern of Banda Aceh City tends to lead to the East. This is mostly caused by the shape of the land which is very suitable to be used as a built-up area
