Abstract

Studi literatur ini berisi tentang pengaruh pengadukan proses biogas yang dihasilkan dari proses biogas MSW (Municipal Solid Waste) dan Sampah Organik. Metode yang digunakan yaitu dengan review 15 jurnal terkait proses biogas dengan pengadukan dan tanpa pengadukan, kemudian dianalisa, dan disimpulkan. Penelitian ini bertujuan mengetahui hasil produksi biogas MSW (Municipal Solid Waste) dan sampah organik menggunakan pengadukan dan tanpa pengadukan terhadap jumlah gas metana yang dihasilkan. Hasil analisa mendapatkan data tertinggi menggunakan pengadukan yaitu sebesar 717 liter dengan kecepatan pengadukan 10 rpm berbahan baku kotoran sapi + limbah rumah potong hewan dengan waktu fermentasi 20 hari berkapasitas ±5,2 liter dibandingkan dengan hasil yang tidak menggunakan pengadukan menghasilkan sebesar 102,9 liter berbahan baku kotoran sapi dan rumput gajah berkapasitas 100 liter waktu fermentasinya 60 hari. Hal ini dapat disesuaikan berdasarkan pernyataan teori bahwa proses pengadukan dapat menggeser waktu produksi biogas satu atau dua hari lebih awal dibandingkan reaktor yang tidak dilakukan pengadukan, sehingga dengan pengadukan akan mempercepat terbentuknya biogas.
