Abstract

ABSTRACTCaulerpa lentillifera is one of the potential seaweed commodities and is known as sea grapes. This study aims to determine the maceration extraction technique of C. lentillifera in stages using different polarity solvents. The method used in this research is experimental, namely the extraction of C. lentillifera by graded maceration using solvents of different polarity consisting of n-hexane (non polar), ethyl acetate (semi polar), and methanol (polar) with a comparison of sample to solvent (1:3 w/v) for 72 hours. The extract was filtered with whatman paper and evaporated using a rotary vacuum evaporator at a temperature of ± 40°C to obtain a thick extract. Parameter analysis calculation of yield of each extract produced from different solvents. The results showed that the average yield of each extract of n-hexane, ethyl acetate, and methanol was 0.36%, respectively; 0.39%; and 0.42%. The lowest yield was from n-hexane extract and the highest was methanol extract.Keywords:Sea grape; C. lentillifera; extraction method; graded maceration

Abstract

AbstractEel is one type of fish that can be used because it has a high nutritional content. Eel can be used as raw material for fish meal because it is known to contain complete protein and amino acids. This study aims to determine the chemical composition of eel flour which is dried in the sun and oven. The research method used was an experiment by making eel flour dried in an oven and in the sun. Parameter analysis of chemical composition and calcium content. The results showed that using a drying oven using a light oven produced moisture (9.35%), ash (3.80%), protein (81.01%), fat (2.07%), calcium (2.66%). Eel flour was dried in the sun compared to using the sun with moisture, ash, protein, fat content, 9.99, 77. 60, 2.07%, and calcium content of 2.66%. The results showed that the eel flour which was dried in the sun and oven had different chemical compositions. Oven-dried flour is better than sun-dried flour.Key word: Chemical composition, calcium, dried method

Abstract

ABSTRACT               Vanname shrimp (Liptonaeus vannamei) is widely consumed by the community, on the other hand, the skin waste is underutilized. Shrimp shell has a potential use as a chitin product. Chitin can be isolated from shrimp shell by demineralization and then deproteination their shells. The demineralization process was carried out using citric acid. This study aimed to determine the effect of different pH on the use of citric acid in the manufacture of chitin. The research method used was experimental composed as a non-factorial completely randomized design (CRD) with 3 treatment levels, namely K1(pH 4), K2(pH 5) and K3 (pH 6). The best characteristics of vannamei shrimp waste chitin with citric acid at pH 4 indicated by the highest yield of 48.82%, water content 2.18%, ash content 3.30%, and the degree of deacetylation of 40.3%. Keywords:Chitin, Citric acid, pH, Vanname shrimp
