Abstract

Rawa Kucing Final Disposal Site serves 13 districts and has a solid waste generation of 1400–1500 tons daily. The existing treatment at Rawa Kucing Leachate Treatment Plant makes it difficult to degrade organic contaminant using conventional treatment. The leachate in the effluent cannot meet the quality standards on PERMENLHK or Regulation of Ministry of Environment and Forestry Number 59 2016, with a pH content of 8.21; BOD of 251 mg/L; COD of 867 mg/L; TSS of 287 mg/L; Total Nitrogen of 231 mg/L, while the Mercury and Cadmium content are <0.0005 and <0.003 mg/L. UV and H2O2 were used in this research to determine the performance of Advanced Oxidation Process in the BOD, COD, TSS, and Total Kjeldahl Nitrogen concentrations, as well as to analyze the optimum condition that affects the operation of the UV/H2O2 process.
Leachate effluent samples from Rawa Kucing Final Disposal Site are treated using UV and H2O2 by forming hydroxyl radicals by photolysis and oxidation of hydrogen peroxide with UV light catalysts. The use of operational process parameters, namely parameters of variations in H2O2 doses and variations in UV irradiation intensity resulting from variations in the distance of UVC lamps, affect the removal efficiency of contaminants which was obtained from analyzing the initial concentration of BOD, COD, TSS, and Total Kjeldahl Nitrogen parameters, then the experiment using a laboratory scale photochemical reactor and analyzing the final concentration of BOD, COD, TSS, and Total Kjeldahl Nitrogen parameters. Dosage variations were carried out based on the ratio of H2O2/COD concentration values, namely 1.063; 2.125 and 4.250. The irradiation distance variations were 24 cm, 33 cm, and 42 cm.
This study shows that the effectiveness of UV/H2O2 as post-treatment can reduce BOD concentration by up to 66% from 127.21 mg/L to 58.87 mg/L; COD concentration by up to 78% from 1310 mg/L to 290 mg/L; TSS concentration up to 57% from 535 mg/L to 228 mg/L; and Total Kjeldahl Nitrogen concentration up to 75% from 123.43 mg/L to 30.5 mg/L. With the optimum condition to decrease BOD, COD, TSS, and Total Kjeldahl Nitrogen on average H2O2 dosage of H2O2/COD = 4.250 and irradiation distance 24 cm.

Tempat Pembuangan Akhir Rawa Kucing melayani 13 kabupaten dan memiliki timbulan sampah 1400-1500 ton setiap hari. Perawatan yang ada di Unit Pengolahan Lindi Rawa Kucing sulit untuk mendegradasi kontaminan organik menggunakan pengolahan konvensional. Lindi dalam efluen tidak memenuhi baku mutu pada PERMENLHK atau Peraturan Menteri Lingkungan Hidup dan Kehutanan Nomor 59 Tahun 2016, dengan kandungan pH 8.21; BOD 251 mg/L; COD 867 mg/L; TSS 287 mg/L; Total Nitrogen sebesar 231 mg/L, sedangkan kandungan Merkuri dan Kadmium adalah <0,0005 dan <0,003 mg/L. UV dan H2O2 digunakan dalam penelitian ini untuk mengetahui kinerja Proses Oksidasi Lanjut pada konsentrasi BOD, COD, TSS, dan Total Kjeldahl Nitrogen, serta untuk menganalisis kondisi optimum yang mempengaruhi pengoperasian proses UV/H2O2.
Sampel limbah lindi dari Tempat Pembuangan Akhir Rawa Kucing diolah menggunakan UV dan H2O2 dengan membentuk radikal hidroksil melalui fotolisis dan oksidasi hidrogen peroksida dengan katalis sinar UV. Penggunaan parameter proses operasional, yaitu parameter variasi dosis H2O2 dan variasi intensitas penyinaran UV yang dihasilkan dari variasi jarak lampu UVC, mempengaruhi efisiensi penghilangan kontaminan yang diperoleh dari analisis konsentrasi awal parameter BOD, COD, TSS, dan Total Kjeldahl Nitrogen, kemudian percobaan menggunakan reaktor fotokimia skala laboratorium dan menganalisis konsentrasi akhir parameter BOD, COD, TSS, dan Total Kjeldahl Nitrogen. Variasi dosis dilakukan berdasarkan rasio nilai konsentrasi H2O2/COD yaitu 1.063; 2.125 dan 4.250. Variasi jarak penyinaran adalah 24 cm, 33 cm, dan 42 cm.
Penelitian ini menunjukkan bahwa efektivitas UV/ H2O2 sebagai post-treatment dapat menurunkan konsentrasi BOD hingga 66% dari 127.21 mg/L menjadi 58.87 mg/L; Konsentrasi COD hingga 78% dari 1310 mg / L menjadi 290 mg / L; Konsentrasi TSS hingga 57% dari 535 mg / L menjadi 228 mg / L; dan konsentrasi Total Kjeldahl Nitrogen hingga 75% dari 123.43 mg/L menjadi 30.5 mg/L. Dengan kondisi optimum penurunan BOD, COD, TSS, dan Total Kjeldahl Nitrogen rata-rata dosis H2O2 berdosis perbandingan konsentrasi H2O2/COD = 4.250 dan jarak penyinaran 24 cm.
