Abstract


Pulau Poteran merupakan salah satu pulau terbesar yang dimiliki oleh Kabupaten Sumenep dengan sektor prioritas pengembangan sumber daya perkebunan. Hasil penelitian sebelumnya menunjukan kandungan bahan organik tanah pulau Poteran sangat rendah. Penelitian ini dilakukan untuk mengetahui potensi eksoenzim yang dihasilkan bakteri tanah desa Talango, pulau Poteran, dalam mendegradasi bahan organik, dan mengetahui genus bakteri tersebut. Potensi eksoenzim dihitung dengan indeks amilolitik pada medium starch agar, indeks proteolitik pada medium Bushnell-Haas Casein 1%, indeks selulolitik pada CMC agar, dan indeks lipolitik pada Tween 80-pepton agar. Karakterisasi bakteri dilakukan menggunakan kunci dikotomi berdasarkan buku Bergey’s Manual Determinative of Bacteriology hingga tingkat genus. Penelitian ini mendapatkan empat isolat bakteri tanah desa Talango yang berpotensi proteolitik dan selulolitik, dua isolat diantaranya berpotensi amilolitik, dan dua isolat berpotensi lipolitik. Setelah dilakukan karakterisasi dan identifikasi kelima isolat bakteri tersebut cenderung terbagi ke dalam dua genus yaitu Corynebaterium, dan Aeromonas.
