Abstract

ABSTRACTFreshwater mussleclamsis one of the mollusks that is originated in freshwater. The meat of the Freshwater mussle clams was widely consumed but itsshells werestill unused and so becoming as the waste. However, clamshells have the potential to become a chitin product.The production of chitin and chitosan in the deproteination process using chemical method can damage the quality of the chitin and chitosan. This study aimed to determine the best concentration of papain enzymes fortheclamshells deproteination. The treatment conducted in this research was in the using of papain enzyme at different concentrations (15%, 20%, and 25%) for the deproteination process of clamshell. The amount of protein hydrolyzed was determined by using Kjeldahl method.The results obtained the best chitin characteristics in the K3 treatment, namely levels3.23% water, 7.45% ash content, and 4.60% protein contentKeywords:Chitin, Deacetylation, deproteination, Freshwater mussleclams, Papain enzym

Abstract        This study aimed to determine the best concentration of papain enzymes on fish protein hydrolysate, including non-protein nitrogen, proximate chemical composition, yield, and total amino acids. This research was carried out in 3 stages, namely 1) preparation of fish meat, 2) Making of fish flour, 3) Making of fish protein hidrolysate. The results showed that the use of papain enzymes had affected significantly to the characteristics of the protein hydrolysate and the concentration of papain 14% was the best concentration in making the mudskipper protein hydrolysate. The product contain of non-protein nitrogen was 8,2259 mg/l, water was 65.00% (w/w), ash was 8.83% (d/w), fat was 1.67% (d/w), and protein was 80.00% (d/w).   Keywords: enzym papain, hydrolysis of protein, mudskipper

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
