Infrastructure Development Strategy for Sustainable Wastewater System by using SEM Method (Case Study Setiabudi and Tebet Districts, South Jakarta)

Abstract

The root of pollution problem that occurs in water surface and groundwater is the unavailability of adequate wastewater infrastructure in order to anticipate the rapid development of city with large populations [2]. Jakarta as a capital city with population of 9.733.880 million from the total area of 650 km2, only has 3% of its total population served by piping system, which are in Setiabudi and Tebet district. The Masterplan of wastewater and drainage (1991-2010) has been made with assistance from JICA through central government, and now it is under evaluation and compilation of new Masterplan 2012-2050 with JICA's. There was no significant progress in wastewater infrastructure development from 1991 to 2001. To know why the wastewater infrastructure is undeveloped and its obstacle issues, it needs a reaserch conducted to society, management, and the government as decision maker. This research is done by using the SEM Method to 270 respondents. The result of this research shows the pathway coeficient which has positive and significant influence to the sustainability which are intitution (0.203), environmental (0.197), technology selection (0.156), financial/economy (0.146) and social-culture (0.128). Those coeficients are used to compile the development strategy for wastewater infrastructure.
