KEANEKARAGAMAN BAKTERI TANAH PENDEGRADASI BAHAN ORGANIK DI DESA TALANGO DAN DESA POTERAN PULAU POTERAN

ABSTRAK

Pulau Poteran merupakan salah satu pulau terbesar yang dimiliki oleh Kabupaten Sumenep dengan sektor prioritas pengembangan sumber daya perkebunan. Hasil penelitian sebelumnya menunjukkan kandungan bahan organik tanah pulau Poteran sangat rendah. Penelitian ini dilakukan untuk mengetahui potensi eksoenzim yang dihasilkan bakteri tanah desa Talango dan desa Poteran pulau Poteran dalam mendegradasi bahan organik dan mengetahui keanekaragaman 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 dan indeks lipolitik pada Tween 80-Pepton agar. Karakterisasi bakteri dilakukan menggunakan kunci dikotomi berdasarkan buku Bergeys Manual determinative of Bacteriology hingga tingkat genus. Penelitian ini mendapatkan total 49 isolat bakteri diantaranya 17 isolat bakteriberasal dari desa Talango dan 32 isolat bakteri berasal dari desa Poteran. Terdapat 29 isolat bakteri yang menunjukkan potensi amilolitik 45 isolat bakteri menunjukkan potensi proteolitik 32 isolat bakteri menunjukkan potensi selulolitik dan hanya 14 isolat bakteri yang menunjukkan potensi lipolitik. Setelah dilakukan karakterisasi dan identifikasi isolat tersebut diduga terbagi menjadi lima belas genus yaitu Bacillus Corynebacterium Micrococcus Staphylococcus Pseudomonas Aeromonas Vibrio Escherichia Morganella Proteus Providencia Edwardsiella Shigella Yersinia dan Lampropedia.


ABSTRACT

Poteran island is one of the largest islands in Sumenep the priority sector is plantation resource development. Results of previous studies indicate that soil organic matter content is very low. This study was conducted to determine the potential of soil bacteria exoenzyme in Talango and Poteran village Poteran island in degrading organic matter and determine the bacterial diversity. Exoenzyme potential calculated by the amylolytic index on starch agar medium proteolytics index on Bushnell-Haas Casein 1 medium cellulolytics index on CMC agar medium and lipolytic index on Tween 80-Peptone agar medium. Characterization of bacterial conducted using dichotomous keys based on Bergeys Manual of determinative Bacteriology up to the genus level. This study get 17 isolates of bacteria from the Talango village and 32 isolates of bacteria from Poteran village. Isolates that have potential of amylolytic totaled 29. Isolates that have potential of proteolytic totaled 45. Isolates that have potential of cellulolytic totaled 32. Isolates that have potential of lipolytic totaled 14. After characterization and identification of suspected isolates divided into fifteen genera are Bacillus Corynebacterium Micrococcus Staphylococcus Pseudomonas Aeromonas Vibrio Escherichia Morganella Proteus Providencia Edwardsiella Shigella Yersinia and Lampropedia.
