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

ABSTRACTBerunok is a type of marine biota that lives on muddy coasts and seagrasses but has not high economic value. This study aimed to determine the effect of different concentrations of acetic acid on the yield and chemical composition of collagen from sea cucumbers. The research method used was a non-factorial completely randomized design (CRD) with 3 treatment levels by repeating 3 times, namely 0.50 M acetic acid concentration, 0.75 M acetic acid concentration and 1 M acetic acid concentration. Parameters for analysis were analysis yield, and chemistry (water and protein). The results showed that the yield values extracted with acetic acid concentrations of 0.50 M, 0.75 M and 1 M were 2.74%, 3.56% and 5.07%, respectively. The chemical composition consisted of water content and protein extracted with acetic acid concentrations of 0.50 M, 0.75 M, 1 M respectively 17.15%, 14.21%, 11.54% and protein successively 75.69 %, 78.26%, and 79.21%. Keywords: Collagen, yield, Proximate Sea Cucumber

Abstract

ABSTRACTThis study aimed to determine the yield of Caulerpa lentillifera extracted with polar (methanol p.a.), semi-polar (ethyl acetate p.a.) and non-polar (n-hexane p.a.) solutions. The research method was explorative, the data is analyzed descriptively. The analysis parameter was yield. The results showed that Caulerpa lentillifera extracted with different solvent solutions had successively methanol, ethyl acetate, and n-hexane yields of 0.70%, 0.58%, 0.53%. The highest yield value was produced by methanol extract (polar) of 0.70%. Keywords: Caulerpa lentillifera dried, extract, identification, yield.
