S Situ Pedongkelan merupakan situ alami yang terletak di Kelurahan Tugu,Kecamatan Cimanggis, Kota Depok, Jawa Barat. Penelitian ini bertujuanmenganalisis sumber-sumber pencemar perairan, mengetahui kualitas air dan statusmutu air, menghitung laju degradasi pencemar, menghitung tingkat kesuburanperairan, serta menganalisis daya tampung beban pencemar. Penelitiandilaksanakan pada bulan Agustus 2022-Januari 2023. Pengambilan sampel kualitasair dilakukan pada 6 (titik) dengan menggunakan metode grab sampling. Parameterkualitas air yang dianalisis dalam penelitian ini, yaitu suhu, Total Suspended Solid(TSS), pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD),Chemichal Oxygen Demand (COD), Nitrat (NO3-N), Fosfat (PO4), dan E. coli.Kualitas air dibandingkan dengan baku mutu berdasarkan Peraturan PemerintahNomor 22 Tahun 2021, Lampiran VI, kelas 2 (dua). Terdapat 4 (empat) parameteryang melebihi baku mutu, yaitu BOD5, COD, PO4 dan E. coli. Status mutu airmenggunakan Indeks Pencemaran (IP) sebesar 8,42 (tercemar sedang). Koefisienlaju degradasi segmen A 0,61 mg/L/hari; segmen B 0,20 mg/L/hari; dan segmen C-0,32 mg/L/hari. Tingkat kesuburan perairan Situ Pedongkelan melalui N/P rasioadalah 0,54 (kesuburan rendah). Daya tampung beban pencemar untuk parameterBOD5 adalah 31,97 kg/tahun dengan beban existing 117,41 kg/tahun sehinggakelebihan beban 3,67 kali ; daya tampung beban pencemar COD adalah 266,39kg/tahun dengan beban existing 408,23 sehingga kelebihan beban 1,53 kali ; dayatampung beban pencemar PO4 adalah 0,32 kg/tahun dengan beban existing 13,93kg/tahun sehingga kelebihan beban 43,56 kali ; daya tampung beban pencemarNO3-N adalah 106,56 kg/tahun dengan beban existing 103,40 kg/tahun sehinggatidak terjadi kelebihan beban karena hanya -0,97 kali ; daya tampung bebanpencemar E. coli adalah 1,1 x 104 jml/tahun dengan beban existing 2,9 x 106jml/tahun sehingga kelebihan beban 268,49 kali dari daya tampung beban pencemaryang dimiliki oleh Situ Pedongkelan.
P Pedongkelan Lake is a natural lake which located in Tugu Village, CimanggisDistrict, Depok, West Java. This research aims to analyze the pollutant sources,determine the water quality and status water quality, calculate the rate ofdegradation of pollutants, calculate the fertility level, and analyze the pollutant loadcarrying capacity. This research was conducted in August 2022-January 2023.Water quality samples were taken at 6 (points) using the grab sampling method.The air quality parameters analyzed in this research were temperature, TotalSuspended Solid (TSS), pH, Dissolved Oxygen (DO), Biochemical OxygenDemand (BOD5), Chemical Oxygen Demand (COD), Nitrate (NO3-N), Phosphate(PO4), and E. coli. Water quality were compared with the quality standards basedon Government Regulation Number 22 of 202, Appendix VI, Class 2 (two). Thereare 4 (four) parameters that exceed the quality standard, which are BOD5, COD,PO4 and E. coli. The water quality status was carried out using the Pollution Index(IP) and the score of water quality is 8.42 (moderately polluted) The coefficient ofdegradation rate of segment A is 0.61 mg/L/day; segment B is 0.20 mg/L/day; andsegment C is -0.32 mg/L/day. The fertility rate of Pedongkelan lake through theN/P ratiois 0.54 (low fertility). The pollutant load carrying capacity of the BOD5 is31.97 kg/year with the existing load of 117.41 kg/year so it is 3.67 timesoverloaded; the pollutant load carrying capacity of the COD is 266.39 kg/year withthe existing load of 408.23 kg/year so it is 1.53 times overloaded; the pollutant loadcarrying capacity of the PO4 is 0.32 kg/year with the existing load of 13.93 kg/yearso it is 43.56 times overloaded; the pollutant load carrying capacity of the NO3-Nis 106.56 kg/year with the existing load of 103.40 kg/year so there is no overloadbecause it is only -0.97 times; the pollutant load carrying capacity of the E. coli is1.1 x 104 million/year with the existing load of 2.9 x 106 million/year so it is 268.49times overloaded of the pollutant load capacity of Situ Pedongkelan.
