ABSTRAK
Ikan yang dijual di pasar tidak menutup kemungkinan terkontaminasi oleh bakteri.
Penelitian ini bertujuan untuk mendeteksi adanya cemaran bakteri Shigella sp. pada ikan kuniran
(Upeneus sulphureus) di pasar Al-Mahira Banda Aceh. Penelitian ini menggunakan metode survei
cross-sectional dan pengambilan sampel menggunakan metode sampling jenuh (sensus).
Pemeriksaan sampel menggunakan metode Carter. Sampel yang digunakan pada penelitian ini
sebanyak 12 ekor ikan, yang diambil dari 4 pedagang ikan di pasar Al-Mahira Banda Aceh. Ikan
dibedah secara aseptis dan ususnya diambil kemudian dimasukkan ke dalam media Nutrient Broth
(NB) dan diinkubasi pada suhu 37℃ selama 24 jam. Kemudian dilakukan penanaman pada media
Salmonella Shigella Agar (SSA) dan diinkubasikan kembali pada suhu 37℃ selama 24 jam. Hasil
penanaman pada media SSA menunjukkan bahwa semua sampel positif terkontaminasi Shigella sp.
yang ditandai dengan adanya bulat berwarna bening pada koloni yang ditanam. Selanjutnya koloni
bakteri yang tumbuh dilakukan pewarnaan Gram dan diperiksa secara mikroskopis. Hasil pewarnaan
Gram menunjukkan bakteri yang terlihat berwarna pink/merah dan berbatang pendek, yang
menunjukkan bakteri tersebut adalah genus Shigella sp. Dari hasil penelitian dapat disimpulkan
bahwa semua sampel yang diperiksa positif tercemar bakteri Shigella sp.

ABSTRACT Fish sold in the market does not rule out being contaminated by bacteria. This study aims to detect the presence of bacterial contamination Shigella sp. on kuniran fish (Upeneus sulphureus) at Al-Mahira market Banda Aceh. This study used a cross-sectional survey method and sampling using the sampling jenuh method. Samples were examinated using the Carter method. The samples used in study were 12 fish taken from 4 fish traders in the Al-Mahira market Banda Aceh. Fish were dissected aseptically and their intestines were removed and the put in Nutrient Broth (NB) media and incubated at 37 ℃ for 24 hours. Then it was planted on Salmonella Shigella Agar (SSA) media and re-incubated at 37 ℃ for 24 hours. The results of planting on SSA media showed that all positive samples were contaminated with Shigella sp. which was indicated by presence of clear colored circles on the planted column. Futhermore, the column of bacteria that grew was stained with Gram stain and examined microscopically. The result of Gram staining showed that the bacteria were pink/red and had short trunks, which indicated that the bacteria were of genus Shigella sp. The result of the study can be concluded that all samples used were positively contaminated with Shigella sp. Keywords : Al-Mahira Market, Kuniran Fish, Shigella sp.
