Ikan depik (Rasbora tawarensis) merupakan spesies ikan endemik Danau Laut Tawar yang memiliki nilai ekonomi dan ekologi penting bagi masyarakat sekitar. Peningkatan aktivitas domestik di danau dapat menyebabkan pencemaran air yang berdampak pada kualitas dan keamanan ikan sebagai bahan pangan. Penelitian ini bertujuan untuk mengetahui tingkat kontaminasi Salmonella sp. pada ikan depik yang berasal dari Tempat Pendaratan Ikan (TPI) dan ikan depik yang dijual di Pasar Paya Ilang Takengon. Penelitian ini menggunakan metode survei dengan pendekatan cross-sectional. Pengambilan sampel dilakukan satu kali secara acak dari tiga nelayan di TPI Danau Laut Tawar dan dua pedagang ikan di Pasar Paya Ilang Takengon. Sampel diuji menggunakan media Salmonella Shigella Agar (SSA) di Laboratorium Kesmavet FKH USK. Hasil penelitian menunjukkan bahwa seluruh sampel ikan depik dari kedua lokasi terkontaminasi Salmonella sp. Ini menunjukkan adanya keterkaitan antara sumber ikan dari TPI dan kontaminasi yang terdeteksi pada ikan yang dijual dipasar, serta mengindikasikan bahwa kontaminasi berasal dari lingkungan danau yang telah tercemar. Berdasarkan hasil penelitian yang telah dilakukan terhadap sampel ikan depik (Rasbora tawarensis) di TPI Danau Laut Tawar dan pasar Paya Ilang Takengon yang diperiksa menunjukkan hasil positif terkontaminasi oleh Salmonella sp. dengan persentase 100%.

Depik fish (Rasbora tawarensis) is an endemic species of Lake Laut Tawar that holds important economic and ecological value for the surrounding community. Increased domestic activities in the lake area may cause water pollution, which affects the quality and safety of fish as a food source. This study aimed to determine the contamination level of Salmonella sp. in depik fish originating from the Fish Landing Site (TPI) and those sold at Paya Ilang Market in Takengon. This research used a survey method with a cross-sectional approach. Samples were collected once randomly from three fishermen at the TPI of Lake Laut Tawar and two fish vendors at Paya Ilang Market. The samples were tested using Salmonella Shigella Agar (SSA) at the Veterinary Public Health Laboratory, Faculty of Veterinary Medicine, Syiah Kuala University. The results showed that all depik fish samples from both locations were contaminated with Salmonella sp. This indicates a connection between the source of fish from the TPI and the contamination detected in fish sold at the market, suggesting that the contamination originated from the lake environment. Based on the examination of depik fish (Rasbora tawarensis) samples from TPI Lake Laut Tawar and Paya Ilang Market in Takengon, the results confirmed a 100% contamination rate by Salmonella sp.
