Analisis Parameter Fisika dan Kimia Outlet Ipal komunal Domestik Dusun Sukunan di Pusat Pengembangan Teknologi Tepat Guna Pengolahan Air Limbah (PUSTEKLIM) Yogyakarta

The domestic communal Wastewater Treatment Installation (IPAL) of Sukunan Village treats domestic wastewater generated from household activities. However, the wastewater treatment carried out does not guarantee the quality of the wastewater produced. In this study, several parameters were tested at the outlet of the domestic communal of Sukunan Village such as TDS, TSS, BOD, and pH. The tests for TDS and TSS levels were carried out using the gravimetric method, that is weighing the mass obtained after separation. BOD levels were tested using the iodometric method (azide modification), which was to determine the volume of sodium thiosulfate (Na2S2O3) solution used for titration of iodine (I2) which was released on the 0th and 5th day samples. While the determination of the pH value is done using universal pH. Based on the test, the TDS level is 1440 mg/L, TSS is 80 mg/L, BOD is 70.5625 mg/L, and has a pH of 7. This shows that there are parameters that exceed the domestic wastewater quality standard. The parameter is TSS, while the parameters TDS, BOD, and pH meet the requirements
