Screening Profile Albumin dan Protein Ikan Air Tawar Konsumsi di Perairan Sungai Deli, Kota Medan, Provinsi Sumatera Utara

Abstract

The research was located in the Deli River which is located in Medan City, North Sumatra Province regarding the Albumin and Protein Content Test of Consumed Freshwater Fish. This research was conducted in June 2023- July 2023. The Deli River is an aquatic ecosystem that has an important role in producing freshwater fish for consumption. Human activities around the Deli River can affect the decline in water quality and quantification of freshwater fish consumed in the river, so it is necessary to test the albumin and protein content in freshwater fish consumed in the Deli River. The research used three stations, namely Upstream, Central and Downstream. From the three stations, three types of fish were found at each station, namely Tilapia (Oreochromis sp.), Snakehead Fish (Channa sp.) and Catfish (Clarias sp.). The samples that were obtained were tested for albumin and protein content using the Lowry method, namely by measuring the wavelength using a spectrophotometer. The results of this research show that the albumin and protein profiles have an accuracy value of % recovery, namely 100%. The RSD values of albumin and protein profiles have accuracy, precision and precision between >2%. With the % recovery and RSD values, the results obtained have met the requirements, namely % recovery in the range of 98- 102% and RSD < 2%.
