Abstract
Desa Siraisan merupakan salah satu desa di Kabupaten Padang Lawas yang berada di hulu Sungai Barumun. Sungai Barumun dimanfaatkan sebagai tempat pengaliran air hujan yang keberadaannya tidak dapat dipisahkan dari aktivitas manusia di sekitar DAS (Daerah Aliran Sungai). Kegiatan masyarakat yang berada di sekitar sungai berpengaruh terhadap peningkatan jumlah limbah ke badan Sungai Barumun yang berpotensi menurunkan kualitas air sungai. Penelitian terhadap badan air Sungai Barumun yang melintasi kawasan Desa Siraisan perlu dilakukan untuk mengetahui kondisi status mutu air Sungai Barumun dan mengetahui indeks pencemarannya. Hal ini dilakukan sebagai upaya dalam pemantauan kualitas, pengelolaan kualitas dan pengendalian pencemaran Sungai Barumun. Pengambilan sampel dilakukan dengan menggunakan metode grab sampling dengan titik sampling sebanyak 3 titik selama 3 hari, yaitu pada bagian sungai sebelum memasuki Desa Siraisan (T1), bagian sungai yang mewakili kawasan Desa Siraisan (T2) dan bagian sungai setelah melewati Desa Siraisan (T3). Parameter yang dianalisis adalah suhu, pH, DO, BOD, COD, nitrat dan fosfat. Hasil pengujian air sungai menggunakan baku mutu berdasarkan Peraturan Pemerintah Republik Indonesia Nomor 22 Tahun 2021 dan dilanjutkan dengan penentuan status mutu air menggunakan metode indeks pencemaran. Nilai indeks pencemaran pada titik T1 yaitu 1,67 dan memiliki status mutu air tercemar. Nilai indeks pencemaran pada titik T2 dan T3 memenuhi status baku mutu air dengan nilai indeks pencemaran 0,63 dan 0,62.
English Abstract
Siraisan Village is one of the villages in Padang Lawas Regency which is located in the upper reaches of the Barumun River. The Barumun River is used as a place for rainwater to flow, whose existence cannot be separated from human activities around the watershed area. Community activities around the river have an effect on increasing the amount of domestic waste to the body of the Barumun River which has the potential to reduce the quality of river water. Research on the water body of the Barumun River that crosses the Siraisan Village area needs to be done toknowing the condition of the water quality status of the Barumun River and knowing its pollution index. This is done as an effort in quality monitoring, quality management and pollution control of the Barumun River. Sampling was carried out using the grab sampling method with 3 sampling points for 3 days, namely:on the river section before entering Siraisan Village (T1), the river section representing the Village areaSiraisan (T2) and part of the river after passing Siraisan Village (T3). Parameters analyzed were temperature, pH, DO, BOD, COD, nitrate and phosphate. The results of river water testing use quality standards based on Government Regulation of the Republic of Indonesia Number 22 of 2021 and continue with determining the status of water quality using the pollution index method. The pollution index value at point T1 has a lightly polluted water quality status with a pollution index value of 1.67. The pollution index at points T2 and T3 meet the status of water quality standards with a pollution index value of 0.63 and 0.62.
