Extraction of dissolved protein of Channa Striata from Tarakan, North Borneo, as a source of fish serum albumin has been done. Albumin is a water-soluble protein and it is applied in various fields, including health, industry, and technology. The many benefits of albumin make albumin very important. However, albumin is a protein found in the body of living things, so it is necessary to perform the separation process. One of the living things that contain relatively high albumin is snakehead fish ( Channa striata ). The dissolved protein was extracted from snakehead fish meat using water as a solvent at a temperature of 50 °C. The protein obtained was characterized using proximate analysis and Fourier Transform Infra Red (FTIR) Spectrophotometer. The proximate analysis showed that the water, the fat, and the protein content were 8.67%, 3%, and 64.18%, respectively. The FTIR spectrum showed an amide group at 1600-1700 cm −1 which is important in the albumin functional group. This study shows that snakehead fish in Tarakan, North Kalimantan has the potential as a source of fish serum albumin.
