ANALISIS SUHU, DERAJAT KEASAMAN (pH), CHEMICAL OXYGEN DEMAND (COD), DAN BIOLOGYCAL OXYGEN DEMAND (BOD) DALAM AIR LIMBAH DOMESTIK DI DINAS LINGKUNGAN HIDUP SUKOHARJO

Abstract

Domestic wastewater is waste water originating from businesses and/or activities in settlements, restaurants, offices, commerce, apartments and dormitories that have the potential to pollute the environment. This is due to the temperature, power of hydrogen (pH), Chemical Oxygen Demand (COD), and Biologycal Oxygen Demand (BOD) values that are not in accordance with the Regulation of the Ministry of Environment and Forestry of the Republic of Indonesia Number: P.68/Menlh/Setjen/Kum.1/8/2016 concerning Domestic Wastewater Quality Standards. To overcome this, it is necessary to analyze the waste before it is disposed of in the environment. Laboratory analysis of domestic wastewater samples with code 063/AL/Lablingk_DLH/2021 includes determination of temperature, pH, COD and BOD levels. Temperature analysis was performed using a thermometer, pH analysis was performed using a pH meter, COD analysis was performed using a UV-Vis spectrophotometer and BOD analysis was performed using the iodometric titration method. The results obtained were a temperature value of 25.95 oC, a pH value of 7.415, a COD value of 13.299 mg/L and a BOD value of 1.512 mg/L. The results of the analysis of temperature, pH, COD and BOD showed numbers below the threshold quality standard for domestic waste
