Abstract
Baterai MFC merupakan bahan bakar penghasil potensial listrik dari oksidasi substrat organik dengan bantuan mikrobial. Salah satu faktor yang berperan dalam menentukan besar-kecilnya produksi listrik pada baterai MFC adalah konsentrasi substrat. Pengembangan baterai MFC berhubungan dengan substrat yang mudah dijangkau, contohnya adalah maltosa. Penelitian ini bertujuan untuk menentukan pengaruh konsentrasi substrat maltosa dalam baterai MFC, menentukan potensial listrik maksimum dengan variasi konsentrasi substrat maltosa menggunakan Lactobacillus bulgaricus, dan menentukan potensial standar maltosa (E°maltosa) berdasarkan persamaan Nernst. Pengukuran potensial listrik dilakukan pada variasi konsentrasi substrat maltosa 3-7%. Bakteri Lactobacillus bulgaricus dapat tumbuh dalam substrat maltosa dan mengalami peningkatan jumlah seiring dengan peningkatan konsentrasi substrat. Potensial listrik yang dihasilkan berhubungan dengan aktivitas bakteri terhadap substrat dan toksisitas pada bakteri mengakibatkan penurunan potensial listrik. Hasil pengukuran potensial dan arus listrik pada variasi konsentrasi 3-7% berturut-turut, 0,57 V; 0,51 V; 0,48 V; 0,46 V; 0,39 V. Secara teori menggunakan persamaan Nersnt diperoleh E°maltosa sebesar +0,5637 Volt. Hasil tersebut menunjukkan bahwa konsentrasi substrat berpengaruh dalam sistem baterai MFC.
