Performance evaluation of sewage treatment plants in the building of Gowa Engineering campus

Abstract

One of the severe problems caused by anthropogenic activities is wastewater that is not appropriately treated. Faculty of Engineering Campus in Gowa, for instance, is one of the areas in Makassar City that has implemented an integrated sanitation system, namely STP (Sewage Treatment Plants). The type of research used in this study is quantitative analysis based on the evaluation. The research aims to evaluate the efficiency of the STP in the Engineering Faculty of Gowa by testing some parameters such as Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), pH, Chemical Oxygen Demand (COD), oil and Grease from inlet and outlet samples. The purpose of the study is also comparing the evaluation results with the standard of Governor of South Sulawesi no. 69 of 2010 regarding quality standards and criteria for environmental damage in Makassar. Based on the evaluation results, all the parameters of STP in the Centre of Scientific (CSA) building, Classroom, Architecture, Civil, Naval, and Geology have met the quality standards. However, only in the COT building, some parameters do not meet the quality standard, which is TSS, BOD, and COD. It shows that the performance of STP in the faculty of engineering campus has worked well but not ideal.
