Berdasarkan Hasil Pengamatan Dilapangan, Sudah Banyak Udang Yang Dibudidayakan Di Tambak Tradisional Terserang Berbagai Penyakit, Salah Satunya Adalah Bakteri Vibrio Sp. Tujuan Dari Penelitian Ini Adalah Untuk Mengidentifikasi Bakteri Vibrio Sp Yang Terdapat Di Air Tambak Tradisional Kota Tarakan. Penelitian Ini Akan Dilaksanakan Dari November 2015 Sampai April 2016. Uji Bakteri Dilakukan Di Stasiun Karantina Ikan Dan Pengendalian Mutu Kelas II, Kota Tarakan, Berdasarkan Sampel Air Dari Tambak Tradisional Kota Tarakan Di 3 Kecamatan Kota Tarakan, Yakni Kecamatan Tarakan Utara, Tarakan Barat Dan Tarakan Timur. Pengambilan Sampel Sebanyak 2 Titik Yakni Didalam Dan Diluar Tambak. Sampel Air Diambil Dengan Botol Yang Sudah Disterilkan, Kemudian Untuk Di Identifikasi Di Laboratorium. Sampel Kemudian Di Tabulasi Untuk Kemudian Di Analisis Secara Deskriktif Dengan Pendekatan Studi Literatur Yang Sesuai, Dan Ditunjang Dengan Data Kualitas Air Tambak Serta Hasil Identifikasi Dari Beberapa Pengujian Bakteri. Dari Hasil Penelitian Diketahui Bahwa Bakteri Jenis Vibrio Sp Teridentifikasi Di Dua (2) Tempat Berbeda, Yaitu Di Kecamatan Tarakan Barat Dan Tarakan Timur. Jika Melihat Dari Kualitas Air Tambak, Adanya Kemiripan Kualitas Air Tambak Antara Kedua Tempat Tersebut Memungkinkan Terjadinya Kontaminasi Bakteri Ini, Sedangkan Pada Tambak Tarakan Utara Tidak Ditemukan Bakteri Ini Karenakan Dominanya Bakteri Anaerobiospirillium Dan Bakteri Actinobacillus.

Based On The Observation In The Field, There Are Many Shrimps That Was Cultured By Traditional Ponds Has Infected From Many Species Bacterial. One Of Them Was Vibrio Sp. The Aim In This Research Was To Identify Of Vibrio Sp. Bacteria In Traditional Pond Waters At Tarakan City. This Research Did From November 2015 To April 2016. Bacterial Test Did At Quarantine Station Fish And Quality Control Class Two, Tarakan City. Based On The Water Sample Was Taken From Traditional Pond In Three District That Are North Of Tarakan, West Of Tarakan, East Of Tarakan. Sample Was Took From Both Of Pond. Sample Of Water Took In The Sterile Bottle, Than To Identified At Laboratories. And Then This Sample Was Tabulated To Analist Descriptive Scale With Literature Approach Suitable And Support Of The Data Water Quality In Pond. From The Result, Known That Species Vibrio Bacterial Was Identified In Two Location Different, Both Of District West Of Tarakan And East Of Tarakan. If View From Water Quality There Has Similarity Water Quality Pond Between Both Of The Probably Occur Contamination Vibrio Bacteria, Meanwhile In The Pond North Of Tarakan Not Found Vibrio Bacteria, Which Of The Domination Are Bacrterial Anaerobiospirillium And Bacterial Actinobacillus.
