FAKTOR-FAKTOR YANG MEMPENGARUHI PERKEMBANGAN FISIKAL KAWASAN KORIDOR ANTARA KOTA PURWOKERTO � SOKARAJA (THE INFLUENCE FACTOR OF PHYSICAL DEVELOPMENT OF CORRIDOR AREA BETWEEN PURWOKERTO � SOKARAJA)

ABSTRACT The urban development of Purwokerto and Sokaraja was creat a physical urban sprawl fenomena on corridor area. It is covers the size of change from agricultural land to non¬agrcultural land, the presence of urban functions, new residential localities and change in physical conditions of the community's houses. A question, why the intensity of the physical development of three zones a long the corridor area are distinctive ? The aims of this research are: 1) to find out about the effects of internal factors (the condition of the natural physic of environment, accesibility, social and economics condition and the community's perception of land value) on physical development of corridor area between Purwokerto-Sokaraja. 2) to find out about the effects of external factors (the policy of urban development and the non-native residents' view on the environmental condition of the corridor area) on the physical development of corridor area between Purwokerto and Sokaraja.. 3) to find out about the pattern and intensity of spatial development of the corridor area. The research was conducted in the corridor area, which covers the strip of land on both side of the roads between Purwokerto and Sokaraja,Banyumas Regency. The area was divided into three zones on the basis of their distinction of physical appearance. The consisted of 33 heads of household (KK) for zone 1, 56 for zone 2 and 42 for zone 3, taken by non¬random sampling (purporsice sampling). Hypothesis testing was carried out by using a simple linear regression analysis, product moment correlation and cross tabulation. The result of this research were : 1) with regard to the external factors, the policy of urban development of Purwokerto and Sokaraja, the presence of non-native residents and their views on the condition of the corridor area show a positive correlation with the size of the change from agricultural land to non-agricultural land and the number of new residential in the corridor area,. 2) with regard to the internal factors : (a) the income levels of families positively correlate with the physical conditions of the main building of their houses, (b) the household heads' perceptions of the value of agricultural land negatively correlate with the size of change from agricultural land to non¬agricultural land, (c) accessibility positively correlates with the size of change from agricultural land to non-agricultural land, and the size of buildings coverage at each zone, 3) the spatial development pattern of non-residential buildings tend to be linear a long the road and the highest intencity of them at zone 3. The spatial development of residential buildings tend to be cluster back of the non-residential buildings and the highest of them at zone 1. Key words : corridor area, zone, accesibility
