Abstract

WATER QUALITY STATUS IN THE TABUNGANEN MUARA RIVER FLOW SUB-REGION BARITO DISTRICT KUALA SOUTH KALIMANTAN PROVINCE

Sub DAS Tabunganen Muara merupakan anak sungai yang mengalir ke sungai besar Barito Kuala dimana sungainya adalah pasang surut. Berdasarkan pengukuran kualitas air pada variabel Suhu, TSS, pH dan DO dengan perhitungan sistem nilai air menggunakan Metode STORET dan mengacu pada standar baku mutu air sungai Peraturan Pemerintah Nomor 22 Tahun 2021. Status mutu air pada Sub DAS Tabunganen Muara kelas satu dan dua semua stasiun kriteria cemar ringan dan kelas tiga stasiun I, stasiun II kriteria memenuhi baku mutu sedangkan stasiun III kriteria cemar ringan. Kelas empat semua stasiun kriteria memenuhi baku mutu. Total skor nilai negatif hanya pada parameter kimia yaitu variabel DO. Berdasarkan analisis uji beda variabel Suhu, TSS, pH dan DO, keseluruhan tidak berbeda antara status mutu air pada Sub DAS Tabunganen Muara.

The Tabunganen Muara sub-watershed is a tributary that flows into the large Barito Kuala river where the river is tidal. Based on water quality measurements on the variables Temperature, TSS, pH and DO by calculating the water value system using the STORET Method and referring to river water quality standard standards Government Regulation Number 22 of 2021 Status of water quality in the first and second class of the Tabunganen Muara Sub-watershed for all criteria stations lightly polluted and third class station I, station II criteria meet quality standards while station III criteria are lightly polluted. Class four all criteria stations meet quality standards. The total score is negative only on chemical parameters, namely the DO variable. Based on the analysis of the different test variables for temperature, TSS, pH and DO, there was no overall difference between the status of water quality in the Tabunganen Muara sub-watershed.
