Abstract

P enelitian dilakukan di Daerah Aliran Sungai (DAS) Citarum bagian hilir berawal dari Jl. Demang, Karawang dan berakhir di Muara Gembong, Kabupaten Bekasi dengan waktu penelitian mulai dari Bulan Februari â€“ Juli 2019. Tujuan dari penelitian ini adalah untuk mengidentifikasi sumber pencemar potensial, menganalisis kualitas air dan daya tampung beban pencemar serta membuat skenario penurunan beban pencemar Sungai Citarum bagian hilir sepanjang 108,5 km. Parameter yang dianalisis pada penelitian adalah suhu, kekeruhan, DHL, pH, DO, BOD, COD, nitrat, dan fosfat. Metode yang digunakan untuk identifikasi sumber pencemar dilakukan dengan melakukan survey lapangan, analisis kualitas air dilakukan sesuai dengan SNI dan dibandingkan dengan baku mutu menurut KEPGUB Jawa Barat No. 39 Tahun 2000, serta analisis daya tampung beban pencemar (DTBP) BOD, COD, nitrat, dan fosfat dengan menggunakan model QUAL2Kw. Pengambilan sampel dilakukan dengan menggunakan metode grab sampling pada bulan Maret, April, dan Juni 2019 di 10 titik utama sungai dan 1 titik anak sungai sebagai point source. Hasil identifikasi sumber pencemar potensial di Sungai Citarum bagian hilir didominasi oleh pemukiman, pertanian, industri, dan kegiatan domestik lainnya yaitu rumah makan dan warung. Hasil analisis kualitas air untuk parameter BOD berkisar 3,54 mg/L-16,21 mg/L, COD berkisar 19,20 mg/L-48 mg/L, nitrat berkisar 0,24 mg/L-1,2 mg/L, dan fosfat berkisar 0,68 mg/L-2,82 mg/L dengan parameter yang melebihi baku mutu meliputi BOD, COD, dan fosfat. Hasil simulasi model DTBP rata-rata untuk parameter BOD sebesar 19615,45 kg/hari, COD sebesar 32692,42 kg/hari, nitrat sebesar 32692,42 kg/hari, dan fosfat sebesar 653,85 kg/hari dengan beban pencemar rata-rata BOD sebesar21346,06 kg/hari, COD sebesar 91556,36 kg/hari, nitrat sebesar 1639,97 kg/hari, dan fosfat sebesar 4401,09 kg/hari sehingga persentase beban yang harus diturunkan untuk BOD,COD, dan fosfat berturut-turut adalah sebesar 10%, 64%, dan 85%. Terdapat 3 skenario penurunan beban pencemar. Skenario 1 yaitu pemasangan IPAL komunal untuk pemukiman memiliki kelebihan BOD rata-rata sebesar 1%, kelebihan COD rata-rata sebesar 56%, kelebihan fosfat rata-rata sebesar 82%. Skenario 2 yaitu penambahan debit dari Bendung Curug memiliki kelebihan BOD rata-rata sebesar 1,3%, kelebihan COD sebesar 25%, kelebihan fosfat rata-rata sebesar 9%. Sedangkan, skenario 3 yaitu pemasangan IPAL komunal dan penambahan debit memiliki kelebihan BOD sebesar 0%, kelebihan COD rata-rata sebesar 4%, dan kelebihan fosfat srata-rata sebesar 7%.

T he research was conducted in the downstream Citarum River watershed started from Jl. Demang, Karawang and ends in Muara Gembong, Bekasi Regency with the research period starting from February - July 2019. The purpose of this research was to identify potential sources of pollutants, analyze water quality and capacity of pollutant loads and create scenarios for the reduction of pollutants in the Citarum River section downstream along108.5 km. The parameters analyzed in the study were temperature, turbidity, conductivity,pH, DO, BOD, COD, nitrate, and phosphate. The method used to identify pollutant sources is done by conducting a field survey, water quality analysis is carried out in accordance with SNI and compared with quality standards according to KEPGUB West Java No. 39 of 2000, and analysis of BOD, COD, nitrate, and phosphate pollutant load capacity (PLC) using the QUAL2Kw model. Sampling was carried out using the grab sampling method in March, April and June 2019 at 10 main points of the river and 1 point of the tributary as a point source. The results of identification of potential pollutants in the downstream Citarum River are dominated by settlements, agriculture, industry, and other domestic activities, namely restaurants and stalls. The results of water quality analysis for BOD parameters ranged from 3.54 mg/L-16.21 mg/L, COD ranged from 19.20 mg/L-48 mg/L, nitrate ranged from 0.24 mg/L-1.2 mg/L, and phosphate ranges from 0.68 mg/L-2.82 mg/L with parameters that exceed the quality standards including BOD, COD, and phosphate. The average PLC model simulation results for BOD was 19615.45 kg/day, COD was 32692.42 kg/day, nitrate was 32692.42 kg/day, and phosphate was 653.85 kg/day with the average of pollutant load of BOD was 21346.06 kg/day, COD was 91556.36 kg/day, nitrate was1639.97 kg/day, and phosphate was 4401.09 kg/day so that the average of percentage of load that must be reduced for BOD, COD, and phosphates were 10%, 64%, and 85%. There were 3 scenarios for reducing pollutant load. First scenario was applying communal WWTP for settlements has an average overload of BOD was 1%, average overload of COD was 56%, average overload of phosphate was 82%. Second scenario was adding flowrate from Curug Weir have an average overload BOD was 1,3%, average overload of COD was25%, and average overload of phosphate was 9%. Meanwhile, third scenario was applyingcommunal WWTP and adding flowrate scenario has an average overload of BOD was 0%, average overload of COD was 4%, and average overload of phosphate was 7%.
