Short Communication: Proximate analysis, amino acid profile and albumin concentration of various weights of Giant Snakehead (Channa micropeltes) from Kapuas Hulu, West Kalimantan, Indonesia. Biodiversitas 21: 1196-1200. Fish is an important foodstuff due to its nutritional value and high protein. One of popular fish as a foodstuff in tropical Asia is giant snakehead fish (Channa micropeltes). This study aims to examine the proximate composition, amino acid profile, and albumin concentration of giant snakeheads in various weights and to determine the best weight of giant snakeheads according to the proximate, amino acid, and albumin concentration. This research used natural-caught giant snakehead as a material of study, which was categorized into 4 weight sizes consisting of 4-5 grams (B1), 6-14 grams (B2), 15-34 grams (B3), 35-300 grams (B4). Based on the results of the test, the highest water content was found in B1 of 80.5%, the highest levels of protein and fat were in the B4 group of 16.8% and 1.7%, respectively. The highest total amino acid profile was found in B4, with the highest composition of essential amino acids, lysine, which was 2.02%, while the composition of the highest non-essential amino acid in glutamate was 3.60%. The highest albumin levels were in the B4 group which was 16.7%. According to the result of this research, the best weight to consume according to the proximate analysis (Protein, fat content), amino acid profile, and albumin concentration is a giant snakehead at the weightiest of 35-300 grams (B4). Keywords: Albumin level, amino acid, Channa micropeltes, Kapuas Hulu, West Kalimantan INTRODUCTION The giant snakehead fish (Channa micropeltes) is one of the foodstuffs in tropical Asia (Benziger et al. 2011). They belong to Channidae in Channiformes and have been distributed in the fresh waters of Southeast Asia, such as the Malaysia peninsula, Menam River, Mekong River, Sumatra Island (Jiang et al. 2016). The giant snakehead is also popular and widely available in the area of West Kalimantan (Roberts 1989). Based on statistics from the Department of Maritime Affairs and Fisheries of West Kalimantan Province (2014-2017), the total of Giant Snakehead production from natural catches has increased significantly, total catches of 1,924 tons in 2015, and increased to 6,572 tons or of 241.57% in 2017. Channa micropeltes are consumed for their dietary proteins, mainly protein albumin (Fitriyani 2018). Some studies found that consuming snakeheads is good for human body to keep healthy (Jacob et al. 2008). Consuming snakehead also lead to accelerating the wound healing process (Nicodemus et al. 2015). Nevertheless, the snakehead can also enhance dermal wound healing, to reduce post-operative pain and discomfort (Jais et al. 1994), and treatment of skin conditions such as eczema. The studies on the determination of tensile strength of healed wounds treated with giant snakeheads have indicated the efficacy of the fish in wound healing (Baie and Sheikh 2000a, 2000b). In West Kalimantan, giant snakeheads (Channa micropeltes) were caught in various weight ranging from small to adult, even reaching weights> 2 kg per individual. The bodyweight of the snakehead affects the content of albumin (Asikin and Kusumaningrum 2018). However, practical information about the chemical composition such as albumin and amino acid profile of the Giant Snakehead (Channa micropeltes) is not known based on variations in size. So this study aims to analyze the proximate, amino acid profile and albumin levels of giant snakeheads in various sizes.
