KAJIAN DAYA DUKUNG WILAYAH DI DAERAH PINGGIRAN KOTA SEMARANG

Urban sprawl of Semarang that has spread to the urban fringe and surrounding areas, particularly to the south, making the process much land conversion occurs. Based RTRW Kota Semarang 2011-2031 , a urban fringe of the city of Semarang has a way of planning as a function of settlement, agriculture, and conservation. Semarang urban fringe area still has the potential of land to be built into the settlement area. However, on the other hand the existence of agricultural land and forest production still need to be preserved . This study examines aspects of the carrying capacity of the region for the benefit of regional development in the Kecamatan Mijen, Gunungpati, Banyumanik, and Tembalang, using three (3) types of bearing capacity calculation approach, namely: Agricultural environmental carrying capacity, carrying capacity protection function, and the carrying capacity of settlements. The purpose of this research include: analyzing the carrying capacity at district level in 2000 and 2008, the carrying capacity of the projected conditions in 2028, and compiled a typology of regions and provide policy input. Data processing is done in the secondary data in 2000 and 2008. Both the statistical data, as well as image data and spatial. Statistical data mathematically processed and mapped with regular intervals and classification method according to applicable regulations. In this study using Landsat 7 ETM+ imagery, and processed with a supervised classification method. Overview carrying capacity in 2028 is determined by the rate of population growth and land use changes. To prepare the area typology, use the method of K- Means Clustering. Results of this study indicate that the carrying capacity of the region and its quality is impaired . Physiographic factors (physical appearance) and demographic (population) affect the carrying capacity of the existing conditions. While the urban and accessibility factors influence indirectly. Typology of regions formed by 4 (four) clusters. Cluster 1 has the advantage of supporting functions that are still protected. Cluster 2 has the advantage in the agricultural environment that was supportive. Cluster 3 has the advantage that all existing functions and cluster 4 only superior in function of settlements are still supportive. According to the spreading pattern, cluster 1 to cluster in the western region and cluster 4 to cluster in the eastern part
