Wiratmojo, M. Adi and Dr.Eng.Ir. Tri Budi Prayogo,, ST.,MT and Emma Yuliani,, ST.,MT.,Ph.D. (2023) Studi Pengaruh Tata Guna Lahan Daerah Sub-Urban Sungai Brantas Ruas Kota Malang Terhadap Nitrat Dan Fosfat Dengan Pemodelan Qual2Kw. Sarjana thesis, Universitas Brawijaya.
Abstract
Sungai Brantas mengalir dan melintasi Kota Malang berpotensi mengalami penurunan kualitas air akibat perubahan tata guna lahan dan peningkatan jumlah penduduk di daerah Sub-Urban sepanjang sungai. Penelitian dilakukan pada bulan Februari-Maret-April tahun 2022 sepanjang ± 4,0 km. Penelitian ini bertujuan untuk mengidentifikasi kondisi eksisting kualitas air Sungai Brantas, besar Indeks Kualitas Air (WQI) di Sungai Brantas, mengitung beban pencemar, serta daya tampung beban pencemar pada Sungai Brantas dengan paket program Qual2Kw. Parameter pencemar utama adalah Nitrat dan Fosfat. Kegiatan di sekitar Sungai Brantas yang menjadi potensi pencemaran di bagian hulu adalah pertanian, serta bagian hilir adalah domestik. Hasil dari penelitian nilai kadar nitrat 3,24-3,56 mg/l (memenuhi baku mutu kelas II). Kadar fosfat berkisar antara 10,2-11.94 mg/l (melebihi baku mutu kelas II). Indeks Kualitas Air (WQI) pada sungai adalah masuk kelas 6 tercemar kotor. Daya Tampung Beban Pencemar untuk Nitrat adalah 7,481 kg/hari dan untuk Fosfat adalah 1,359 kg/hari. Sungai masih mampu menampung beban pencemar harian Nitrat dan Fosfat.
English Abstract
The Brantas River flows and crosses Malang City with the potential to experience a decrease in water quality due to changes in land use and an increase in population in Sub-Urban areas along the river. The research was conducted in February-March-April 2022 along ± 4.0 km. This study aims to identify the existing condition of the water quality of the Brantas River, the magnitude of the Water Quality Index (WQI) in the Brantas River, to calculate the pollutant load, as well as the carrying capacity of the pollutant load on the Brantas River with the Qual2Kw program package. The main pollutant parameters are Nitrate and Phosphate. Activities around the Brantas River that are potential for pollution in the upstream part are agriculture, and the downstream part is domestic. The results of the study showed that the value of nitrate levels was 3.24-3.56 mg/l (meets class II quality standards). Phosphate levels ranged from 10.2-11.94 mg/l (exceeding class II quality standards). The Water Quality Index (WQI) in the river is classified as dirty polluted class 6. Pollutant Load Capacity for Nitrate is 7.481 kg/day and for Phosphate is 1.359 kg/day. The river is still able to accommodate the daily pollutant load of Nitrate and Phosphate.
