Daftar Isi:
- Bedadung River is one of the main rivers in Jember Regency. Along with the river flow of the Sumbersari Subdistrict and Kaliwates Subdistricts, there is an anthropogenic activity in the form of densely populated housing and agricultural land that produces organic and inorganic waste. Such activities that are directly related to the river have the potential to increase the burden of pollution. The resulting pollution load can potentially lower water quality. The purpose of this study is to analyze the water quality and the rate of deoxygenation and reoxygenation of the Bedadung River Segment Sumbersari-Kaliwates District using the Streeter-Phelps method. Data collection in the form of water debit, TSS, DO, BOD, and COD with grab sampling. The results of the calculation of the rate of deoxygenation and reoxygenation are synthesized using quantitative descriptive methods. The TSS and DO values meet the grade I quality standard but the BOD and COD values do not meet the grade I quality standard. The mean deoxygenation rate (rD) and reoxygenation (rR) were 0.798 mg/L.day and 2.753 mg/L.day, respectively. The value of the reoxygenation rate is greater than the value of the deoxygenation rate. These conditions indicate that the Bedadung River's ability to perform well in reducing organic matter naturally. The size of rR and rD is influenced by the reoxygenation constant, deoxygenation constant, and the hydraulic profile of the river.
- Sungai Bedadung merupakan salah satu sungai utama di Kabupaten Jember. Sepanjang aliran sungai segmen Kecamatan Sumbersari dan Kecamatan Kaliwates ini terdapat aktivitas antropogenik berupa perumahan padat penduduk dan lahan pertanian yang menghasilkan limbah organik maupun an-organik. Kegiatan tersebut yang berhubungan langsung ke sungai berpotensi menambah beban pencemaran. Beban pencemaran yang dihasilkan dapat berpotensi menurunkan kualitas air. Tujuan penelitian ini yaitu menganalisis kualitas air dan laju deoksigenasi serta reoksigenasi Sungai Bedadung Segmen Kecamatan Sumbersari-Kaliwates menggunakan metode Streeter-Phelps. Pengambilan data berupa debit air, TSS, DO, BOD, dan COD dengan grab sampling. Hasil perhitungan laju deoksigenasi dan reoksigenasi disintesis dengan metode deskriptif kuantitatif. Nilai TSS dan DO memenuhi baku mutu kelas I akan tetapi nilai BOD dan COD tidak memenuhi baku mutu kelas I. Nilai rata – rata laju deoksigenasi (rD) dan reoksigenasi (rR) secara berurutan sebesar 0,798 mg/L.hari dan 2,753 mg/L.hari. Nilai laju reoksigenasi lebih besar dari pada nilai laju deoksigenasi. Kondisi tersebut mengindikasikan bahwa kemampuan Sungai Bedadung berjalan dengan baik dalam reduksi bahan organik secara alami. Besar kecilnya rR dan rD dipengaruhi oleh konstanta reoksigenasi, konstanta deoksigenasi, dan profil hidraulik sungai.
