Abstract

Semarang city has a total area of 373,70 km2. Semarang is administratively divided into 16 districts and 177 village, Semarang have astronomical positions between lines 6o50 '- 7o10' south latitude and line 109o35 '- 110o50' east longitude. As the capital of Central Java province, Semarang is a city that is growing economically. Indirectly, the economic development in the city of Semarang influences the spatial growth of the city.The purpose of this research is to create a growth model spatial map of Semarang by using the concept of spatial analysis. Data used in the form of raster data. Namely, Landsat 2002, 2007, 2013, and 2015 along with attribute data of Semarang City with shapefile format. The data in this study were processed using supervised classification method combined with multi-criteria evaluation methods.The results of this study showed that the spatial growth occurs towards the south in the period 2002-2007, and spatial growth occurred in the east in the period 2007-2013, and growth in all directions in the period 2013-2015. Then, seen from the pattern of distribution of economic centers, in the period 2002, 2013, and 2015, the distribution pattern economic centers in the District of Central Semarang and South Semarang shows the distribution pattern clustered, while in the period 2007 distribution pattern economic centers in the District Central Semarang showed clumped distribution pattern while South Semarang exhibit a random pattern on the economic center of the upper classes, while other classes have clumped pattern.
