Abstract

Collagenase was purified from intestines of milkfish (Chanos chanos, Forskal) by extraction,ammonium precipitation, ion exchange chromatography on DEAE Sephadex A-50 and gelfiltration on a Sephadex G-100 column. The purification and yields were 114.731 fold and1.26% when compared to those in the starting-crude extract. The molecular mass of milkfishserine collagenase was estimated to be 14.63 kDa and 27.46 kDa.

Abstract

Consumer demand for commodities is growing, especially for the type of fish that have high economis value, one of which is dumbo catfish (Clarias gariepinus). Handling of the transport system is needed to keep fish alive until the destination. The purpose of this research was to study the effect of light intensity on simulated fish either at rest or moving. The study was conducted with simulation of a closed system transportation for six hours and measuring the water quality each hour. The treatment used were a light simulation, dark simulation, non-simulated light, and dark non-simulation. DO values decrese from 5,0175 ppm to 2,3812 ppm after 6 hours transportation. Water temperature during research at 27,8-29,4˚C. PH values in the study range from 7,2 to 6,3 ppm. The values of carbondioxide increased during transportation. The highest concentration of ammonia presented after six hours in all treatment.The best treatment of this study was non-simulated light.Keywords : Catfish (Clarias gariepinus), closed system transport, water quality

Abstract

The study about chemical and physical characteristics, bioactive compounds and  antioxidant activity of mangrove api-api (Avicennia marina) leaf have been done.  The structure of leaf tissues was analyzed with microscopic method, chemical compositions were determined by proximate analysis, antioxidant activity was determined by DPPH method, while bioactive compounds were determined by phytochemical assay. The microscopic analysis shown that api-api’s leaf have common feature dicotyl leaves structure, but it has a unique additional structure, that was salt extruding gland.  The result of proximate analysis showed that api-api’s leaf was high in crude fiber (4.12%) and carbohydrate (23.00%).  Ethyl acetate extract of api-api’s leaf showed higher antioxidant activity than hexane and methanol extracts, with IC value is 182.33 ppm.  The ethyl acetate extract in concentration 300 ppm had higher ability to inhibite autooxidation that occurred in oil/water emulsion.  Flavonoid, steroid dan reduction sugar were detected in api-api leaf extract.Keywords: antioxidant activity, Avicennia marina, DPPH, flavonoid, salt extruding gland.

Abstract

Marsilea crenata is classified as hydrophytes plant growth in paddy's field, ponds, lakes, swamp or river and called semanggi  as Javanese local name. The plant ethnobotanically used as food by steaming. The research was aimed to describe the histological and chemical composition of leaves and stems as well as the influence of steaming on chemical components. The result showed that the structures of  stalks, stem and root were not equipped with collenchymas tissue. The cortexes consist of many aerenchym as well as the abaxial and adaxial laminas were equipped with a layer of epidermis and the stomata on the upper part of leaf. Leaves and stems contain water, ash, fat, protein, and crude fiber 89%, 2.70%, 4.35%, 2.28% (w/w), respectively. Steaming process reduced about 80% of ash content while the vitamins C, beta carotene and total carotenes content decreased about 17%, 37%, and 43%, respectively. The content of potassium as main mineral dropped 7% due to steaming process. The fresh leaves and stems of Marsilea crenata contain reducing sugar, steroid, carbohydrate, and flavonoids.Keywords: histology, leaf, Marsilea crenata, steaming, stem

Abstract

The research objectives were determine the concentration of lime and soaking time that could reduce the smell of sardine, the concentration of curcumin that could prevent the oxidation of fish, and the effect of curcumin on chemical and microbiology characteristic of sardine abon during 30 days storage. Sardine was soaked in lime solution with concentration from 5 to 20% (v/v) for 10, 20, and 30 minutes. After the best concentration of lime was found, the experiment was continued to determine the optimum concentration of curcumin in maintained he chemical and microbiology characteristic of sardine abon by adding the fish with curcumin from 1% to 5% (w/w). The abon was stored for 30 days andevery 10 days the sensory test, proximate analysis, analysis of water activity (aw), TPC and TBA were carried out. Sensory test showed that the addition of lime until 15% could increase the result, however, the sensory test result depleted when 20% of lime was used. The period of immersion also gave positive correlation with sensory test. The preliminary experiment also showed that the addition of curcumin increased the value of sensory test with 1 and 2% of curcumin gave better result compared with 3, 4 and 5% curcumin. During 30 days storage period, the value of sensory parameters and proximate properties were decrease, meanwhile, the water activity, TPC and TBA were rised. In conclusion, up to 30-day storage period, teh quality of fish abon was decrease,d but still could be accepted by the panelists. Immersion of fish abon on 15% of lime for 30 minutes and addition of 2% curcumin gave better quality of fish abon compared with others treatmen with value of water content 10.71%, ash4.16%, fat 26.82%, protein 30.51%, carbohydrate 27.80%, aw 0.51, TPC 2.45 colonies/ gram, and TBA 1.76mg/kg. The addition of curcumin fish abon did not significantly influence the appearance, water content, ash, fat, and carbohydrates, however the color, aroma, texture, flavor, protein content, water activity (aw), value TBA, and TPC significantly influenced.Keywords: curcumin, fish abon, lime, sencory parameters

Abstract

Crabs (Portunus pelagicus) is one member of the class Crustacea that being a major exported commodity. It is exported mostly in form frozen without head and shell and canned pruduct. Steam process is one important step in crab’s canning industry. This research aimed to study the yield, proximate composition, water-soluble protein, salt-soluble protein, amino acids content and the structure of crabs meat’s tissue analysis in a fresh and after steam process. Fresh crabs has higher yield than the steamed one. Steamed crab’s yield decreased by 14.99%. Proximate composition of fresh and steamed crabs as follows, moisture (wb) 78.47% and 75.43%, ash (db) 7.66% and 6.02%; protein (db) 68.09% and 66.63%; fat (db) 0.84%   and 0.75%, charbohydrate (db) 23.41% and 26.62%; water-soluble proteins (db) 40.87% and 25.32%; salt-soluble proteins (db) 58.06% and 30.77%. Crabs meat contained 15 amino acids, 9 essential amino acids and 6 non essential amino acids. The highest essential amino acid composition was arginin by 6.87% in fresh crab and 6.80% in steamed crab, while the highest non essential amino acid composition was glutamate by 10.92% in fresh crab and 9.81% in steamed crab. Fresh crab meat has connective fibers, while the steamed crab meat has  disjointed and not compact fibers.Key words: amino acids, crab (Portunus pelagicus), meat tissue, protein, steaming.

Abstract

Tanaman lindur (Bruguiera gymnorrhiza) merupakan salah satu tumbuhan mangrove yang biasadimanfaatkan sebagai makanan dan obat tradisional, namun masih belum cukup informasi sebagaisumber antioksidan. Tujuan penelitian ini adalah menentukan komposisi kimia, komponen bioaktif,aktivitas antioksidan, dan kemampuan ekstrak buah lindur dalam menghambat pembentukan bilanganperoksida. Ekstraksi yang digunakan adalah ekstraksi bertingkat dengan tiga jenis pelarut yang memilikitingkat kepolaran berbeda, yaitu n-heksana, etil asetat, dan metanol. Penentuan aktivitas antioksidandilakukan dengan menggunakan metode 1,1-diphenyl-2-picrylhidrazyl (DPPH). Buah lindur memilikikadar air 62,92%, kadar abu 1,29%, kadar lemak 0,79%, kadar protein 2,11% dan kadar karbohidrat32,91%. Hasil ekstraksi menunjukkan bahwa rendemen ekstrak kasar tertinggi dihasilkan oleh ekstraksidengan metanol, diikuti ekstraksi dengan etil asetat, dan n-heksana. Ekstrak metanol memiliki aktivitasantioksidan sangat kuat dengan nilai IC50 sebesar 9,42 ppm. Ekstrak etil asetat dan n-heksana memilikiaktivitas antioksidan sangat lemah dengan nilai IC50 sebesar 443,61 ppm dan 2256,13 ppm. Uji fi tokimiamenunjukkan bahwa ekstrak yang memiliki aktivitas antioksidan terbaik mengandung steroid, fl avonoid,dan tanin. Konsentrasi ekstrak yang memiliki daya hambat terbaik terhadap pembentukan peroksidapada emulsi minyak adalah pada konsentrasi 250 ppm dengan bilangan peroksida sebesar 0,21 Meq/kg.
