Abstract

This research was held in the upper-stream of Ciliwung Watershed on March- September 2007. The research site was divided into 3 zones, Le. the upper-part, the middle-part and the lower-part with village sample in Tugu Utara, Cilember, and Katulampa, respectively. The objectives of research were (I) to evaluate land suitability for housing, (2) to analyze housing condition, (3) to analyze community behavior in environmental management, and (4) to draft recommendation for the development of environmental friendly housing. Land evaluation for housing was performed using the spatial analysis method by GIS Some land characteristics of slope steepness, erosion hazard and existing land utilization were used as evaluation attributes. It's indicated very suitable 1 class (S-I) 51 ha (3.8% the upper-part), 28 ha (9.4% the middle-part), and 183.3 ha (61.2% the J lower-part). Those S-1 areas are lower than the t::xisting housing area (2003), except in the lower- 1 part. Housing characteristic in the upper-part and the middle-part are almost similar, Le. informal, small to medium size~ dense, and linear. In the lower-part was indicated there are two types (formal and informal), large size, dense, and linear. Community waste management behavior in the upper-part and the middle-part are similar. They used public toilet without septic tank; domestic garbage was through out into river directly; drinking water source from spring. Most the lower-part community used private toilet; garbage is r:nanaged by public work agency; and water source from PDAM.
