<![CDATA[ABSTRAKPenelitian ini bertujuan untuk mengisolasi dan mengidentifikasi bakteri Pseudomonas sp pada ikan asin di TPI Labuhanhaji Aceh Selatan. Penelitian ini menggunakan 15 sampel ikan asin dari 3 pedagang. Setiap pedagang diambil sejumlah 5 macam ikan asin, diantaranya ikan asin tongkol, dencis, layur, kembung, dan ikan kepala batu lalu diperiksa di Laboratorium Mikrobiologi Fakultas Kedokteran Hewan, Universitas Syiah Kuala Banda Aceh. Ikan asin di stomacher lalu di swab steril dan dimasukkan ke media Nutrien Broth dan diinkubasikan pada suhu 37oC selama 24 jam, selanjutnya dilakukan penanaman pada media Pseudomonas Agar Base lalu diinkubasikan kembali pada suhu 37o C selama 24 jam. Koloni bakteri yang tumbuh pada media PAB dilakukan pengamatan bentuk bakteri, pigmentasi, permukaan, pinggiran, elevasi dan aspek koloni. Pewarnaan Gram dilakukan untuk memastikan bakteri yang didapat adalah kelompok Gram negatif. Terakhir dilakukan uji IMVIC,uji biokimia Triple Sugar Iron Agar dan uji gula-gula. Hasil penelitian ini di analisis secara deskriptif. Hasil pemeriksaan dari 15 sampel ternyata di temukan adanya pertumbuhan koloni bakteri Pseudomonas sp pada media PAB dan hasil pewarnaan Gram menunjukan Gram negatif. Oleh karena itu dapat di simpulkan bahwa ditemukan bakteri Pseudomonas sp pada ikan asin di TPI Labuhanhaji Aceh Selatan. ABSTRACTThis study was aimed to isolate and identify Pseudomonas sp bacteria in salted fish in Fishing Auction Station (TPI) in Labuhanhaji Aceh Selatan. This study used 15 salted fish as the samples from 3 different traders. From each trader taken a number of 5 kinds of salted fish, including Euthynnus affinis, Sardina piichardus, Trichiurus lepturus, Rastrelliger, and Osmeridae then they were checked in Microbiology Laboratory Faculty of Veterinary Medicine, Syiah Kuala University Banda Aceh. The salted fishs were placed in stomacher continued by putting them in sterile swab then they were put into Nutrient Broth medium incubated at 37oC for 24 hours, then planted on medium Pseudomonas Agar Base followed by incubating them again at 37oC for another 24 hours. Coloni of bacteria that grow on PAB were conducted to observe its bacterial form, pigmentation, surfaces, edges and elevation and the aspects of the colony. Gram staining was underdone to ensure the bacteria are the Gram-negative group. In the last treatment, IMVIC, Triple Sugar Iron Agar biochemical and sugar test were conducted. The result of this research is analyzed descriptively. The Results of examining 15 samples showed that there are the growth of Pseudomonas sp on PAB media and Gram staining results showed Gram negative. Therefore, it can be concluded that the Pseudomonas sp bacteria on salted fish in TPI Labuhanhaji Aceh Selatan were found. ]]>
