diolah Air limbah yang tidak akan berdampak pada kesehatan masyarakat dan lingkungan. Beberapa indikator menunjukkan bahwa pengolahan air limbah tidak optimal di Surakarta. Hal ini dibuktikan dengan dimasukkannya diare sebagai sepuluh penyakit tertinggi yang paling umum di Surakarta. Selain itu, sebagian besar kasus pencemaran air sungai di Surakarta disebabkan oleh air limbah. Oleh karena itu, kota Surakarta perlu menyediakan infrastruktur pengolahan air limbah, terutama untuk perumahan untuk mencegah polusi di sungai. instalasi Tesis ini bertujuan untuk mengevaluasi dampak dari penyediaan pengolahan air limbah pabrik dengan menyelidiki penerimaan publik, mengevaluasi dampak dari pengolahan air limbah terhadap kesehatan masyarakat, kualitas lingkungan perumahan dan kualitas air sungai. Penelitian ini dilakukan di Kota Surakarta. Evaluasi penerimaan publik menggunakan regresi spasial, dampak penyediaan instalasi pengolahan air limbah menggunakan regresi spasial, terutama menggunakan ordinary least square dan geographically weighted regression. instalasi pengolahan Penerimaan masyarakat terhadap penyediaan air limbah dipengaruhi oleh pendapatan, tingkat pendidikan, memberikan informasi, hibah, dan kondisi geografis. Dampak penyediaan instalasi pengolahan air limbah terhadap waterborne diseases adalah 44, 56%, terdapat 13 kelurahan yang mempunyai dampak paling kuat dan dampak pada kualitas lingkungan perumahan sekitar 30, 89%, terdapat 12 kelurahan yang memiliki pengaruh yang paling kuat. Pengolahan air limbah pabrik juga berdampak pada kualitas air sungai.

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.
