ABSTRAK

Penelitian ini bertujuan untuk mengetahui status mutu air menggunakan metode STORET dan Indeks Pencemaran serta mengetahui kelayakan perairan menggunakan metode Environment Quality Index (EQI) di SUB-DAS Martapura Provinsi Kalimantan Selatan. Parameter yang diukur yaitu : suhu, kecerahan, pH (derajat keasamaan), DO (Oksigen Terlarut), Nitrat (NO₃) dan Fosfat (PO₄).

Hasil perhitungan STORET berdasarkanpPPkNo. 82 Tahuno2001 standar baku mutu air (kelas I) menunjukkan nilai (-12) hingga (-28) dikategorikan dengan kriteria sedang yaitu cemar sedang. Berdasarkan perhitungan metode IP sesuai dengan KepMen LH No. 115 tahun 2003 menunjukkan nilai berkisar (1,03 – 1,9) dengan kriteria cemar ringan. Hasil kelayakan perairan dilokasi penlitian dihitung menggunakan metode EQI berkisar (0,17 – 0,22) dengan kriteria buruk dan sangat buruk SUB-DAS Martapura untuk air baku air minum, untuk pemukiman, industri maupun pertanian dikategorikan buruk hingga sangat buruk.

ABSTRACT

This research aims to determine water quality status using the STORET method and Pollution Index and determine the feasibility of waters using the Environment Quality Index (EQI) method in the Martapura Watershed, South Kalimantan Province.

The parameters measured temperature, brightness, pH (degree of acidity), DO (Dissolved Oxygen), Nitrate (NO3) and Phosphate (PO4).

STORET calculation results based on Government Regulations No. 82 of 2001 the water quality standard (class I) shows the value (-12) to (-28) is categorized as medium criteria with medium polluted. Based on the calculation of the IP method by following the judgment of the Minister of Environment No. 115 of 2003 shows values ??ranging from (1.03 - 1.9) with mildly polluted criteria. The results of the water feasibility at the research location calculated using the EQI method ranged (0.17 to 0.22) with poor and very bad criteria. Martapura Watershed for drinking water, for settlement, industry and agriculture is categorized as bad to very bad.
