Abstract


Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi inokulum bakteri Zymomonas mobilis dan lama fermentasi terhadap produksi etanol yang optimum. Penelitian ini dilakukan pada bulan November 2012 sampai Mei 2013 di Laboratorium Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Institut Teknologi Sepuluh Nopember. Penelitian ini menggunakan variasi perlakuan yaitu konsentrasi inokulum (0, 5, 10 dan 15%) dan lama fermentasi (0, 2, 4, 6, dan 8 hari). Masing-masing perlakuan diulangi sebanyak 2 kali, sehingga diperoleh 40 unit percobaan dan dianalisis menggunakan uji ANOVA. Parameter yang diamati adalah kadar etanol. Hasil yang diperoleh dalam penelitian ini adalah kadar etanol optimum sebesar 9,5% (v/v) dihasilkan pada interaksi konsentrasi inokulum 10% dan lama waktu fermentasi 6 hari
