Penelitian ini bertujuan untuk mendeskripsi pengelolaan air lindi di Tempat Pemrosesan Akhir (TPA) Cipayung Kota Depok Tahun 2019. Jenis penelitian ini yaitu deskriptif dengan metode penelitian kualitatif. Penelitian ini menerapkan teori pendekatan sistem dimana terdiri dari unsur-unsur input, proses, dan output . Pada unsur input pengelolaan air lindi mencakup enam hal yaitu man, money, method, machine, dan sarana penunjang. Unsur proses mencakup produksi dan pengolahan air lindi. sedangkan untuk unsur output mencakup kualitas air lindi yang dihasilkan. Data yang digunakan pada penelitian ini yaitu data primer dengan cara pengujian kualitas air lindi dan wawancara terhadap informan penelitian. Hasil penelitian yang didapatkan bahwa pengelolaan air lindi di TPA Cipayung sudah cukup sesuai dengan teori yang diterapkan pada penelitian ini hanya saja beberapa bagian dari unsur yang ada masih belum terpenuhi baik dari segi kualitas maupun kuantitas.

This study aims to describe the management of leachate at Cipayung Landfill (TPA) Depok City in 2019. This type of research is descriptive with qualitative research methods. This research applies a system approach theory which consists of elements of input, process, and output. The input elements of leachate management include six things, namely man, money, method, machine, and supporting facilities. Process elements include production and processing of leachate. while for the output element includes the quality of leachate produced. The data used in this study are primary data by testing the quality of leachate and interviewing research informants. The results showed that the management of leachate in Cipayung landfill was quite in accordance with the theory applied in this study except that only a few parts of the existing elements were still not fulfilled both in terms of quality and quantity.

Pengolahan lindi yang efektif sangat penting untuk mencegah dampak negatifnya terhadap lingkungan dan manusia. Dalam penelitian ini, digunakan Teknik Advanced Oxidation Process (AOPs) berbasis ozonasi dengan Reaktor Plasma Dielectric Barrier Discharge (DBD) Ozone Nanobubble untuk mendegradasi lindi. Udara diinjeksikan ke dalam reaktor, dan melalui reaksi dengan plasma, radikal hidroksil (•OH) dan ozon (O3) dihasilkan sebagai oksidator limbah. Penelitian ini bertujuan untuk menguji efektivitas metode dan menganalis pengaruh laju alir gas dan tegangan reaktor terhadap proses pengolahan lindi. Hasil setelah pengolahan selama 60 menit, terjadi pengurangan Total Suspended Solids (TSS) sebesar 100%, Chemical Oxygen Demand (COD) sebesar 95,5%, Biological Oxygen Demand (BOD) sebesar 71,95%, dan penurunan pH hingga 57,02%. Namun, terjadi peningkatan pada nilai Total Dissolved Solids (TDS) sebesar 436,13% dan Nitrat sebesar 75,27%. Laju alir ditemukan berpengaruh terhadap pH, TSS, COD, dan Nitrat. Sedangkan, tegangan berpengaruh terhadap pH, COD, dan Nitrat. Pada uji TDS ditemukan tidak dipengaruhi oleh laju alir dan tegangan. ......Effective leachate treatment is essential to prevent its negative impact on the environment and humans. In this research, ozonation-based Advanced Oxidation Process (AOPs) Techniques were used with an Ozone Nanobubble Dielectric Barrier Discharge (DBD) Plasma Reactor to degrade leachate. Injected air will react with the plasma thus generating hydroxyl radicals (OH) and ozone (O3) as waste oxidizing agents. This study aims to test the effectiveness of the method and to analyse the influence of gas flow rate and reactor voltage on the leachate treatment process. The results after processing for 60 minutes, there was a reduction in Total Suspended Solids (TSS) by 100%, Chemical Oxygen Demand (COD) by 95.5%, Biological Oxygen Demand (BOD) by 71.95%, and a decrease in pH up to 57.02%. However, there was an increase in the Total Dissolved Solids (TDS) value of 436.13% and Nitrate of 75.27%. Flow rate was found to have an effect on pH, TSS, COD, and Nitrate. Meanwhile, the voltage affects the pH, COD, and Nitrate. In the TDS test it was found that it was not affected by flow rate and voltage.
