Case Study: Wastewater Treatment Plant In Surakarta
Abstract
Untreated wastewater will impact on public health and environment. Therefore, providing Wastewater Treatment Plant (WWTP) is esssential to prevent that impacts. The Local Government of Surakarta has built a treatment plant to improve proper wastewater treatment service for community, protection toward public and environmental health. However,  the usage of WWTP only 25,73 of the target, the degradation of public and environmental health which associated with the wastewater pollution is still occuring. 
This thesis aims to evaluate the impact of wastewater treatment plant provision by investigating public acceptance, evaluate the impact of wastewater treatment plant in the quality of public health, residential environmental and river water. The research was carried out in the City of Surakarta. The evaluation of the usage of wastewater treatment plant is using a spatial analysis and spatial regression, and evaluation of the impact of wastewater treatment plant provision is using a spatial regression, especially using an ordinary least square and a geographically weighted regression.
The result of this research are the level of wastewater treatment plant usage influenced by the level of poverty, level of education, grant scheme, information delivery, and distance. The indicators of public acceptance has the significant influence to the level of wastewater treatment plant usage up to 75, 49%. The wastewater treatment plant usage have the significant relation to the public health and affect for 44, 54 % to public health. The WWTP usage have the significant relation to the residential environmental and have the contribution 30, 09 % to the public health. Centralized WWTP has less impact to river water pollution, but communal WWTP has high impact, due to the effluent of communal WWTP does not meet the quality standard. Future research should be directed to using another method to analyse the problems and than comparing with the result from this research.
