Abstract

Scales of fish represent side product which not yet been exploited optimally. Fish scales in industrial scale (side product of fish fillet industry) can be used as collagen source, while in domestic scale generally only thrown. This research aim to know fish scales potency by determining rendemen, chemical composition and physical, and possibility of existence active component in fish scales. If the target point have been known, hence which wish known hereinafter is influence of fish weight toward content of fish scales. Result of research on fish scales of carp with 260-3.315 gram in weight is rendemen mean of carp scales from 3,0-5,7 %. Carp scales is over three big component which is protein 29,8-40,9%, water 30,0-36,8%, and dusty 18,7-26,3% ( content of calcium 5,0-8,6%). Other component are fat 0,1-1,0 % and carbohydrate by differences 2,0-5,7 % ( content of chitin 0,4-3,7 %). Carp scales is alkalis, pH 8,0-8,7. Carp scales thickness is 0,02-0,07 mm and diameter range is 0,9-2,1 cm. Carp scales contain alkaloid, carbohydrate, compound of peptide, and amino acid. Carp weight have an effect on chitin rate. Ever greater of carp weight, progressively have lower chitin rate at its scales

Abstract

Free radicals are highly reactive a molecule because it has one or more unpaired electrons. Reactivity of free radicals can be inhibited by antioxidant systems. Antioxidants are compounds that can inhibit reactive oxygen species/reactive nitrogen species (ROS/RNA) as well as free radicals. The raw materials are expected to have antioxidant activity is snail papaya. Conch papaya is widely used gastropods waters of Cirebon, West Java. The purpose of this study was to determine the characteristics, yield of crude extract, antioxidant activity and bioactive components of the snail papaya with various kinds of solvents. Test of antioxidant activity using DPPH method. The examination of fitokimia and antioxidant activity which performed on kloroform, etil asetat and methanol extracs with concentration activity antioxidant 200, 400, 600 and 800 ppm. Results yield the largest extraction solvent extraction using methanol (polar), while the smallest yield that is using the solvent ethyl acetate (semi-polar). The highest antioxidant activity contained in the innards of methanol crude extract with IC50 value of 1156 ppm, whereas the lowest activity of the innards that come from crude chloroform extract with IC50 value of 2799 ppm. The antioxidant activity of snail meat or offal papaya has a very low activity. Conch papaya has alkaloids, carbohydrates. Bioactive components in the form of steroid found only in extracts of chloroform and ethyl acetate extract. Bioactive components in the form of an amino acid found only in meat and offal of crude extract of methanol
