Local food has the potential to be expanded in a variety of diversified the fishery products. Therefore analysis of Lawar nutrient content needs to be done. The research objective was to determine the nutrient content of Lawar in Wearlilir waters as raw material for fish pellets. Proximate analysis of Lawar used 1995 OAC method and composition of fatty acids by GC-MS. The Results proximate analysis obtained includes Lawar proximate when blooming in September that consisted of moisture, 13.06%, ash 12.45%, fat 10.55%, and 61.94% protein, and carbohydrates 2.0%, and Lawar proximate when not blooming consists of 20.01% moisture, 12.67% ash content, the fat content of 10.16%, 55.06% protein, 2.1% carbohydrates. Results of analysis of fatty acid composition consist of saturated fatty acids 0.62% strearat acid (C18: 0), 0.22% palmitic acid (C16: 0), cyclopentadecanone 0.14%, 0.06% 3-carboxamide and fatty acids unsaturated 0.23% arachidonic acid (C20: 4, n-6). 6-oktadekanoid 0.08% acid, 9-oktadekanoid acid 0.06%. There were 17 kinds of amino acids, the amino acid is the highest hydroxyprolin 22, 015 mg. Keywords: Lawar, nutrition, fish pellet, proximate 1. Introduction The high biodiversity of Indonesian coastal and marine offers many opportunities to diversify the utilization of biological resources, both in terms of types of biota and kinds of usage. Fishery products that have become their own source of food and income sources in the country and exports, in the form of various types of fish and non-fish continuously sought in a massive scale. To avoid the immense pressure on the usage, we need to look and introduced the kinds of marine biota such as the types of marine worms from Polychaeta class and other invertebrate that has the potential as fishery commodity with high market potential value. One of the aquatic biological resources of Wearlilir is "Lawar" Perinereis cultrifera. Lawar from Wearlilir waters experienced blooming in April, May, September to December, the highest biomass of Lawar (blooming) were in September with an average of 5921 g / 2dm3. No blooming period start from January to March and June to August [7]. One potential alternative material as feed additives is the earthworms because it contains high protein and complete amino acids. The chemical composition of earthworms Lumbricus rubellus flour was 65.63% protein content [2] as well as the amino acid proline approximately 15% of the total 62 amino acids [1], whereas the earthworm species L. Terestris containing 32.60% crude protein [4], earthworm flour Perionyx excavatus containing 57.2% crude protein and contains complete essential amino acids [17], with the provision of earthworm flour (TCT) as poultry feed proved to accelerate the growth of live weight, increase muscle tissue formation, and increase feed efficiency [3]. Antimicrobial activity was also reported there in earthworms. Earthworm Eisenia foetida has glikolipoprotein mixture of G-90 and having inhibition against Staphylococcus sp. higher than the antibiotic Gentamicin 10 mg and 20 mg Enrofloxacin. P. cultrifera worm is used by the Langgur community as one of the popular traditional food for generations [10]. Until now this marine worm is used as the nutritious side dishes with a fairly complete composition of nutrients (Table I). The worms are also sold to supplement the family income with an average price IDR 50,000/kg [6]. With the advantages, P. cultrifera worm has opportunities to be exploited and developed in order to meet the needs of human beings. For instance, it is used as a raw material for food and pharmaceutical industries such as supplement foods or fortified ingredients in food products [12]. Table 1: Nutritional Contents of P. Cultrifera Worm Content Composition Protein 13.5% Fat 0.11% Ash 2.40% Water 76.71% Ca 1814.45 ppm Fe 21.65 ppm Essential amino acids Histidine 0.34% Threonine 0.57% Tyrosine 0.34% Methionine 0.23% Valine 0.68% Phenylalanine 0.53% Isoleucine 0.62% Leucine 0.81% Lysine 0.77% Unsaturated fatty acids palmitoleate acid (C16: 1, n-7) 16 mg oleic acid (C18: 1 n-9) 56 mg linoleic acid (C18: 2, n-6) 15 mg Paper ID: ART20161607 DOI: 10.21275/ART20161607 831
