Abstract

Kappaphycus alvarezii merupakan salah satu jenis rumput laut yang sering terinfeksi penyakit ice-ice dengan ditandai adanya perubahan warna talus rumput laut putih bening atau transparan. Penyakit ini dapat menyebabkan penurunan produksi pada beberapa lokasi budidaya rumput laut. Oleh karena itu, pengendalian penyakit ice-ice melalui karakterisasi dan enumerasi bakteri perlu dilakukan untuk mengetahui lokasi budidaya yang cocok sehingga mampu meningkatkan jumlah produksi rumput laut. Penelitian ini bertujuan untuk mengetahui karakter dan dinamika kelimpahan bakteri yang terdapat pada masing-masing lokasi budidaya rumput laut terkait adanya kemunculan penyakit ice-ice dengan adanya perubahan kondisi lingkungan. Dinamika kelimpahan bakteri di perairan desa Talango, Saronggi, dan Lobuk fluktuatif. Sedangkan dinamika kelimpahan bakteri di perairan desa Palasa selalu meningkat namun jumlah peningkatan dari bulan Desember 2015 sampai April 2016 tidak selalu sama. Karakteristik bakteri yang teridentifikasi pada tiap bulan di seluruh lokasi perairan budidaya rumput laut adalah bakteri Gram negatif dengan kemampuan motilitas untuk melakukan pergerakan ============================================================================================= Kappaphycus alvarezii is one kind of seaweed that often infected by ice-ice disease with discoloration into translucent or transparent white. This disease reduces the productivity of seaweed cultivation in some locations. Therefore restainining of ice-ice disease through characterization and enumeration bacteria has to be conducted to determine the suitable location for cultivation to increase the ammount of seaweeed productivity. This study aims to determine character and total dynamic of bacteria that found in each location of seaweed cultivation related to the occurrence of ice-ice disease with changing environmental conditions. The result showed that total dynamic of microbes in Talango, Saronggi, and Lobuk seaweed cultivation was fluctuative. Whereas total dynamic of microbes in palasa seaweed cultivation increased but the total excalation of bacteria from December 2015 until April 2016 was not equal in each month. Characteristics of bacteria that identified in each month across all locations of seaweed farming was a Gram-negative bacteria with the ability to perform a movements
