Pandemi COVID-19 menyebabkan penggunaan obat-obatan seperti parasetamol (PCT) terus meningkat. Peningkatan konsumsi ini menyebabkan munculnya senyawa PCT di perairan Angke dan Ancol sebesar 0,42 µg/L dan 0,61 µg/L. Penelitian ini bertujuan untuk mempelajari potensi degradasi PCT pada lingkungan anoda sistem Microbial Fuel Cell (MFC) menggunakan konsorsium bakteri lumpur Danau Mahoni Universitas Indonesia. Percobaan dilakukan dengan memvariasikan konsentrasi awal PCT dan pH lingkungan anoda. Hasil menunjukkan bahwa terdapat degradasi PCT pada sistem ini dalam waktu 72 jam. Degradasi PCT sebesar 13,47±1,09%; 11,02±5,43%; dan 28,54±18,84% diperoleh untuk variasi konsentrasi awal 10,21; 20,24; dan 31,45 mg/L. Degradasi PCT juga diperoleh pada variasi pH lingkungan anoda 5,8; 7,0; dan 8,2 sebesar 31,31±3,54%; 11,02±5,43%; dan 48,69±0,86%. Analisis komunitas mikroba juga dilakukan menggunakan metode Next Generation Sequencing (NGS) 16s rRNA dan ditemukan bahwa bakteri yang berperan dalam mendegradasi PCT adalah Burkholderia sp. Hasil ini dapat digunakan untuk mengembangkan teknologi yang efisien dalam menghilangkan PCT pada air limbah farmasi. ......The COVID-19 pandemic has caused the use of drugs such as paracetamol (PCT) to continue to increase. This increase in consumption led to the emergence of PCT compounds in the waters of Angke and Ancol of 0.42 µg/L and 0.61 µg/L. This study aims to study the potential for PCT degradation in the anode environment of the Microbial Fuel Cell (MFC) system using a consortium of University of Indonesia Lake Mahoni mud bacteria. Experiments were carried out by varying the initial concentration of PCT and the pH of the anode environment. The results show that there is PCT degradation in this system within 72 hours. PCT degradation of 13.47 ± 1.09%; 11.02±5.43%; and 28.54 ± 18.84% obtained for variations in the initial concentration of 10.21; 20.24; and 31.45 mg/L. PCT degradation was also obtained at various pH of the anode environment 5.8; 7.0; and 8.2 of 31.31 ± 3.54%; 11.02±5.43%; and 48.69 ± 0.86%. Microbial community analysis was also carried out using the Next Generation Sequencing (NGS) 16s rRNA method and it was found that the bacteria that played a role in degrading PCT was Burkholderia sp. These results used to develop efficient technologies for removing PCT in pharmaceutical wastewater.

Air lindi merupakan air yang telah melalui tumpukan sampah sehingga berpotensi untuk merusak lingkungan dan menimbulkan penyakit. Lindi dapat diolah menggunakan teknik Advanced Oxidation Processes (AOPs) berbasis ozon yang digenerasikan dengan Sistem Reaktor Plasma Dielectric Barrier Discharge (DBD) Ozon Nanobubble dengan umpan gas oksigen. Ozon dan spesies reaktif lainnya berperan untuk mengoksidasi air lindi sehingga dapat menurunkan konsentrasi Chemical Oxygen Demand (COD), Biology Oxygen Demand (BOD), Total Suspended Solid (TSS), Total Dissolved Solid (TDS), dan nitrat (NO3-), serta menetralisir pH larutan yang akan menjadi parameter penelitian. Penelitian dilakukan dengan lindi yang diambil di TPST Bantar Gebang dan diberi pre-treatment koagulasi menggunakan tawas dan filtrasi menggunakan karbon aktif. Penelitian dilakukan selama 60 menit dengan variasi laju alir, tegangan listrik, dan durasi uji. Hasil terbaik yang didapat dari masing- masing parameter percobaan adalah pH dengan penurunan 21,8%, TSS dengan degradasi 100%, TDS dengan kenaikan 514,4%, COD dengan penurunan 91,7%, nitrat dengan penurunan 78,8%, dan BOD dengan penurunan 75,1%. ......Leachate is water that has gone through a pile of garbage so it has the potential to damage the environment and cause disease. Leachate can be processed using the Advanced Oxidation Processes (AOPs) technique with the basis of ozonation generated by the Ozon Nanobubble Dielectric Barrier Discharge (DBD) Plasma Reaktor System with oxygen gas feed. Ozon and other reactive species play a role in oxidizing leachate so that it can reduce the concentrations of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solid (TSS), Total Dissolved Solid (TDS), and nitrate (NO3-), as well as neutralize the pH of the solution which will be the research parameter. This research was carried out with leachate taken at the Bantar Gebang TPST and pre-treated with coagulation using alum and filtration using activated carbon. The research was conducted for 60 minutes with variations in flow rate, voltage, and test duration. The best results obtained from each experimental parameter were pH with 21,8% decrease, TSS with 100% degradation, TDS with 514,4% increase, COD with 91,7% decrease, nitrate with 78,8% decrease, and BOD with a decrease of 75.1%.
