Abstract

Lindi sangat berbahaya bila mencemari lingkungan karena tingginya kandungan organik, logam berat, garam terlarut, asam, dan mikroorganisme yang dapat bersifat patogenik. Kandungan-kandungan tersebut dipengaruhi oleh kondisi iklim, umur landfill, komposisi sampah, dan kondisi geohidrologi. Lindi yang dihasilkan dari landfill berumur tua memiliki tingkat biodegradabilitas yang rendah sehingga cocok diolah secara fisik-kimia. Tingkat biodegradabilitas yang rendah dengan rasio konsentrasi BOD5/COD ≤ 0,1. Lindi pada Unit Pengolahan Sampah Terpadu (UPST) Bantargebang memiliki rasio konsentrasi BOD5/COD = 0,05. Kondisi terkini pengolahan lindi pada instalasi pengolahan air sampah (IPAS), yaitu IPAS 1 dan IPAS 3 memiliki teknologi pengolahan yang bersifat biologis. Metode oksidasi H2O2 merupakan salah satu metode fisik-kimia yang efektif menyisihkan polutan, karena memiliki nilai potensi reduksi tinggi Penelitian ini bertujuan untuk menentukan kemampuan pengolahan lindi dengan metode oksidasi menggunakan H2O2 dan pengaruh pH; waktu reaksi; dosis H2O2, terhadap residu H2O2. Penelitian ini menggunakan lindi inlet IPAS 3 UPST Bantargebang, dengan reaktor, sistem batch menggunakan beaker glass berkapasitas 1 L yang digunakan sebagai reaktor lalu dioperasikan dengan menggunakan magnetic stirrer pada kecepatan rotasi 200 rpm. Reaktor ditutupi dengan aluminum foil agar proses oksidasi tidak dipengaruhi oleh cahaya. Dosis yang digunakan berdasarkan rasio konsentrasi H2O2/COD yaitu 1,0625 dan 2,125. Waktu reaksi yang diterapkan selama 60 menit dan 180 menit. pH lindi awal yang digunakan adalah pH 5, pH 6, pH 7 dan pH lindi asli, yaitu pH 8. Setelah proses oksidasi, sampel dinetralisasi menggunakan NaOH yang bertujuan untuk dekomposisi H2O2 dan penyimpanan sampel. Analisis parameter lindi akhir yang diukur adalah pH, warna, BOD5, COD, TN, TSS, dan residu H2O2. Berdasarkan hasil penelitian ini, variasi yang memiliki nilai optimum pada pH 6, H2O2/COD 2,125, dan waktu reaksi 60 menit dengan rata-rata penyisihan warna, BOD5, COD, TSS, TN, dan H2O2 tereaksikan sebesar 65%. Konsentrasi residu H2O2 yang lebih tinggi didapatkan pada kondisi pH awal lindi yang bersifat asam, dan waktu reaksi yang pendek. Namun, waktu reaksi yang lebih panjang juga dapat menurunkan residu H2O2 seiring dengan meningkatnya pH akibat reaksi oksidasi. Selain itu, konsentrasi awal H2O2 juga mempengaruhi konsentrasi residu H2O2.

Leachate is very dangerous if it pollutes the environment. This is due to the high content of organic matter, heavy metals, dissolved salts, acids, and microorganisms that may be pathogenic. These contents are influenced by climatic conditions, landfill age, waste composition, and geohydrological conditions. The leachate, produced from old landfills, has a low level of biodegradability so it is suitable for physical-chemical processing. The low level of biodegradability has a BOD5/COD concentration ratio at less than 0.1. The leachate that is generated at the Unit Pengolahan Sampah Terpadu (UPST) Bantargebang has a BOD5/COD concentration ratio of 0.05. Currently, the leachate treatment plant for wastewater treatment plants IPAS 1 and IPAS 3 are using biological technology treatment. The H2O2 oxidation treatment method is one of the effective physical-chemical methods in removing leachate pollutants because of the high H2O2 reduction potential. The research aims to determine the ability of leachate treatment by oxidation method using H2O2 and the variation of pH, Reaction time, H2O2 dose on H2O2 residue. The H2O2 oxidation treatment method is one of the effective physical-chemical methods in removing leachate pollutants because of the high H2O2 reduction potential. This study used a sample of leachate inlet pond at IPAS 3 UPST Bantargebang, using a batch reactor system. A glass beaker with a capacity of 1 L was used as the reactor. The reactor was operated using a magnetic stirrer at a rotational speed of 200 rpm. The reactor is covered with aluminum foil so that the oxidation process is not affected by light. Dosage variations were carried out based on the ratio of H2O2/COD concentration values, namely 1,0625 and 2,125. The time variations were 60 and 180 minutes. The pH variations carried out were pH 5, pH 6, pH 7 and the original leachate pH of 8. After the oxidation process, the sample was neutralized using NaOH in order to decompose and to store the H2O2 sample. The final leachate was analysed for determining its concentration of BOD5, COD, TN, TSS, and residual H2O2. Based on this research, the most optimum variation has a value of pH 6, H2O2/COD 2,125, reaction time of 60 minutes with the average removal efficiency of colour, BOD5, COD, TSS, TN, and H2O2 reacted about 65%. Higher H2O2 Residue concentrations were achieved in the initial leachate acidic pH and short reaction time. However, longer reaction time also can reduce H2O2 residue as the pH level increases because of oxidation. Moreover, initial H2O2concentration also affects the H2O2 residue.
