Abstract

Status mutu air merupakan paramater penting yang perlu dianalisis untuk mengetahui kualitas air sungai. Hal tersebut berkaitan dengan kesesuaian peruntukan air sungai. Sungai Tambak Bayan merupakan salah satu sungai kelas II di Daerah Istimewa Yogyakarta yang melintasi kawasan perkotaan dan dimanfaatkan oleh masyarakat. Pada penelitian ini dilakukan analisis status mutu air sungai Tambak Bayan menggunakan dua metode yaitu Storet dan Indeks Pencemaran (IP) sesuai Keputusan Menteri Negara Lingkungan Hidup nomor 115 tahun 2003 tentang Pedoman Penentuan Status Mutu Air. Data kualitas air yang digunakan merupakan data sekunder yang diambil dari database Dinas Lingkungan Hidup dan Kehutanan (DLHK) D.I.Yogyakarta 2013-2020 dengan parameter total suspended solid (TSS), nitrat, nitrit dan total Coliform. Terdapat empat titik pemantauan yang digunakan. Hasil perhitungan status mutu menunjukkan status mutu air sungai Tambak Bayan dengan metode Storet yaitu tercemar berat dan metode IP  yaitu tercemar ringan.

Abstract

Yogyakarta, Indonesia, has various municipal wastewater treatment (IPAL) facilities; however, only 40% are operational. The study examines how IPAL affects groundwater quality and identifies its causes. Ngaglik, one of three province districts with the largest IPAL number and population density, is the research site. This study only measures microbiological groundwater quality based on Total coliforms and Eschericia coli, according to APHA 2017. Inverse distance weighing (IDW) maps microbiological groundwater quality. The results of the study showed that the observed area had Total Coliform values of 0–170 MPN/100 ml and Escherichia coli concentrations of 0–7. Eleven of the twelve test samples met Permenkes drinking water quality requirements No. 492/Menkes/Per/IV/2010 and PerGub DIY No. 20 of 2008. Seven E. coli concentration measurements exceeded drinkable water requirements. This study showed that E. coli bacteria may have infiltrated groundwater near the sample site. The incident was the first sign that Kapanewon Ngaglik Municipal IPAL was malfunctioning. This data should help assess and improve the effectiveness of the municipal IPAL at the study site and other local IPALs.
