The purpose of this study was to evaluate the ability of biocover to oxidize the methane on a certain layer thickness with a continuous flow conditions.

The results showed that the thick er layer of biocover, the higher the efficiency of methane oxidation. The oxidation efficiency obtained in each layer thickness of 15, 25, 35 and 60 cm was 56.43%, 63.69%, 74.58% and 80, 03% respectively, with the rate of oxidation of 0.2 9 mol m -2 d -1 and the fraction of oxidation of 9 9 %. The oxidation result was supported by the identification of bacteria isolated in this experiment, namely metanotrophic bacteria that have the ability to oxidize methane through the form of methanol metabolite. ABSTRAK Penanganan sampah kota di Indonesia pada umumnya dilakukan pada tempat pemrosesan akhir sampah ( TPA ), yang sebagian besar dilakukan dengan cara pengurugan (landfilling) yang cenderung bersifat anaerob (tidak ada oksigen). Cara pengurugan ini biasanya dioperasikan lapis perlapis sehingga memungkinkan terjadinya proses anaerob. Pada kondisi ini dipastikan biogas, yaitu gas metana (CH 4 ) dan CO 2 , akan muncul. Metana adalah gas rumah kaca dengan potensi pemanasan global lebih besar dari CO 2 , dan dapat mengabsorpsi radiasi infra merah 23 kali lebih efisien dari CO 2 pada periode lebih dari 100 tahun. Salah satu c ara yang dapat dilakukan untuk mengurangi gas metana dari landfill yang lepas ke alam adalah dengan m engoksidasinya dengan memanfaatkan material penutup landfill (biocover) sebagai media mikroorganisma pengoksidasi metana . Aplikasi kompos sebagai material penutup landfill merupakan pendekatan dengan biaya rendah untuk mereduksi emisi gas dari landfill sehingga cocok untuk negara berkembang . Biocover yang digunakan pada penelitian ini adalah kompos landfill mining, yaitu kompos yang terdegradasi secara alami di landfill. Tujuan penelitian ini adalah mengevaluasi kemampuan biocover kompos landfill mining dalam mengoksidasi metana pada ketebalan lapisan tertentu dengan kondisi aliran kontinyu. Tiga buah r ea k tor kolom yang digunakan terbuat dari flexy glass berukuran tinggi 70 cm dan diameter 15 cm. Gas metana dialirkan dari bawah reaktor secara kontinyu dengan laju alir 5 ml/menit. Kolom diisi dengan biocover kompos landfill mining dengan ketebalan lapisan 5, 25, 35 dan 60 cm. Hasil percobaan menunjukkan bahwa semakin tebal lapisan biocover, semakin tinggi efisiensi oksidasi metana. Efisiensi oksidasi yang diperoleh pada setiap ketebalan lapisan 15, 25, 35 dan 60 cm adalah masing-masing 56,43%, 63,69%, 74,58% dan 80,03%, dengan laju oksidasi 0,287 mol m -2 d -1 dan fraksi oksidasi 97%. Hasil oksidasi yang diperoleh tersebut diperkuat dengan identifikasi bakteri yang berhasil diisolasi, yaitu bakteri metanotrofik yang memiliki kemampuan dalam mengoksidasi metana melalui metabolit antara berupa metanol. }, issn = {2407-5973}, pages = {179--186} doi = {10.14710/reaktor.14.3.179-186}, url = {https://ejournal.undip.ac.id/index.php/reaktor/article/view/5730} }
