ABSTRAK

Penelitian ini bertujuan untuk mengetahui kualitas air berdasarkan parameter suhu, pH, dan oksigen terlarut (DO) pada Sub Sub Daerah Aliran Sungai (DAS) Kemuning, Kota Banjarbaru, Provinsi Kalimantan Selatan, serta menentukan status mutu air menggunakan metode STORET. Pengambilan data dilakukan secara in situ di tiga stasiun pengamatan selama dua hari berturut-turut dengan interval setiap enam jam. Hasil pengukuran menunjukkan rerata nilai dari ketiga parameter masih memenuhi baku mutu air kelas II sesuai Peraturan Pemerintah No. 22 Tahun 2021. Analisis menggunakan metode STORET menunjukkan bahwa pada hari pertama seluruh stasiun masuk kategori cemar ringan (nilai STORET -6 sampai -9), sedangkan pada hari kedua satu stasiun mengalami penurunan ke kategori cemar sedang (nilai STORET -14), sementara dua lainnya tetap cemar ringan. Hasil ini menunjukkan adanya dinamika kualitas air yang dipengaruhi oleh aktivitas domestik dan kondisi lingkungan sekitar sungai. Penelitian ini diharapkan menjadi rujukan dalam upaya pengelolaan kualitas perairan secara berkelanjutan di wilayah Sungai Kemuning.

ABSTRACT

This study aims to assess water quality based on temperature, pH, and dissolved oxygen (DO) parameters in the Sub-Sub Watershed of the Kemuning River, Banjarbaru City, South Kalimantan Province, as well as to determine the water quality status using the STORET method. Data collection was conducted in situ at three observation stations over two consecutive days, with measurements taken at six-hour intervals. The results showed that the average values of the three parameters remained within the Class II water quality standards in accordance with Government Regulation No. 22 of 2021. The STORET analysis indicated that on the first day, all stations were classified as lightly polluted (STORET scores ranging from -6 to -9), while on the second day, one station declined to moderately polluted status (STORET score of -14), with the other two stations remaining lightly polluted. These findings highlight the dynamic nature of water quality influenced by domestic activities and surrounding environmental conditions. This research is expected to serve as a reference for sustainable water quality management in the Kemuning River region.
