Abstract

Squid (Loligo sp.) is one of fisheries commodities export in Indonesia. Squid has cartilage that can be utilized in the food and non-food sectors. The inner skin of the squid cartilage contains chemical compounds are chitin and chitosan. The objectives of this research are to produce chitosan from squid cartilage and tested the antibacterial effectiveness of chitosan in bacteria Staphylococcus aureus and Escherichia coli. The research method was carried out in twophase; the manufacturing phase of chitosan from squid cartilage and the testing phase for the antibacterial activity of chitosan. The results of the first phase of this study indicate that the chitosan produced meets the quality standards of chitosan with water content 7.82% (bk), ash content 0.57% (bk), nitrogen content 3.18% (bk) and degree of deacetylation 87.43%. Further more the results obtained in the second phase showed that the higher of chitosan concentration, the greater of inhibition zone in the tested bacteria. The best antibacterial activity was found at 0.8% chitosan concentration, with an inhibition zone of 12.8 ± 0.06 mm in E. coli and 11.1 ± 0.12 mm in S. aureus. At a concentration of 0.8% showed a greater inhibitory value when compared to 70% alcohol.

Abstract

Gelatin adalah sejenis protein yang dapat diekstraksi dari tulang dan kulit ikan maupun hewan lainnya. Gelatin bersifat mudah larut dalam air, pada suhu ±71 ºC gelatin akan tercampur secara homogen. Penelitian bertujuan untuk mengetahui pengaruh berbagai konsentrasi enzim papain dalam perendaman tulang ikan tuna. Analisis data dilakukan menggunakan analisis ragam (Anova) dengan uji-F. Hasil analisis menunjukkan rendemen gelatin tertinggi 1.50% pada konsentrasi enzim papain 16% dan rendemen gelatin teredah sebesar 1.39% pada konsentrasi enzim papain 24%. Berdasarkan hal ini dapat dikatakan bahwa konsentrasi enzim papain sebesar 16% v/w dapat meningkatkan rendemen gelatin yang dihasilkan.

Abstract

The development of science and technology has resulted in many mononatrium glutamate (MSG) flavorings which can have side effects for human health. The development of natural flavors needs to be done to reduce side effects for human health. Betell plant sap can be used as a source of protease enzymes that have the potential as active agents in flavor production. Flavors can be obtained from animal protein such as flying fish. The purpose of this study was to determine the best treatment of the enzyme biduri in producing flavored flying fish. This study uses a factorial completely randomized design (RALF) method with concentrations of 1.5%, 2.0%, and 2.5% slurry proteases with a hydrolysis duration of 30, 60, and 90 minutes. The results obtained indicate that the best water content at a concentration of 1.5% hydrolysis time is 90 minutes (47,84%), dissolved protein in concentration 2.5% hydrolysis time 60 minutes (86,83%), total amino acids in concentration 1.5% hydrolysis time 90 minutes (3,11%), and organoleptic value in concentration 1.5%.

Abstract

Sea urchin is an aquatic animal that contains calcium carbonate. Calcium carbonate usually extracted from solid limestone suspension but in this case, calcium carbonate is extracted from sea urchin exoskeleton. The aim of this research is to characterize the calcium carbonate preparation from sea urchin exoskeleton. All steps in this research included destruction, extraction, and precipitation. All characteristic of calcium carbonate preparation from sea urchin exoskeleton is water content 12.83±1.33%, ash 37.10±1.02%, fat content 0.93±0.06%, protein content 2.01±0,67% and carbohydrate by-Difference 47.12±4.12. For characterization of calcium carbonate are rendement 64.29±0.60%, water content 0.69±0.30%, ash 57.23±0.25%, calcium content 25.53±2.50%, and FTIR spectroscopic identified OH¯ dan CO3. Absorbent bend of OH group appears in 3420.57 cm-1 and CO3 group in872.89 – 1416.66 cm-1.

Abstract

Solar dryer is a device that use solar energy to try substances. Using a solar dryer is more hygiene than drying directly into the sun. This experiment aims to construct a solar dryer device and to examine product water content. There are some steps in this experiment which are constructing a solar dryer device and examination of the product water content of two different solar device construction. Products that examined are mackerel tuna dried with salt and without salt. Water content examination is established every 4 hours and 12 hours. All data are examined descriptively. Results showed that temperature in device type 1 are between 40-45 0C dan device type 2 are between 44-45 0C. Results for water content in salted dry fish showed a score of 37.99% in device type 1 and 30.27% in device type 2. For water content in non-salted dry fish showed a score of 38.4% in device type 1 and 27.35% in device type 2. Base on this it can be concluded that device type 2 able to lower water content in products better than device type 1.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui aktifitas anti mikroba dari ekstrak ethanol daun mangrove api-api (avecennia marina) terhadap total mikroba dan staphylococcus epidermidis yang di isolasi dari ikan pinekuhe. Penelitian ini dibagi dalam dua tahap yaitu ekstraksi dengan metode maserasi menggunakan pelarut ethanol 57% hasil destilasi dari minuman captikus dan uji aktifitas anti mikroba metode kertas cakram Kirby Bauer. Metode penelitian yang digunakan yaitu metode penelitian eksperimental dengan rancangan acak lengkap dengan parameter konsentrasi ekstrak yaitu 0%, 20%, 40%, 60%, 80% dan kontrol positif kloroamfenikol. Analisis data menggunakan uji normalitas metode Chi square dan dilanjutkan dengan uji nonparametrik Kruskal Wallis. Hasil pengujian aktifitas anti mikroba terhadap total mikroba tidak menunjukan adanya pengaruh nyata, sedangkan terhadap staphylococcus epidermidis menunjukan adanya pengaruh nyata dengan tingkat kepercayaan 95%. Pengaruh tertinggi yaitu pada konsentrasi 80% dengan diameter zona bening rata-rata yaitu 11,67 mm dan terendah yaitu pada konsentrasi 20% dengan diameter zona bening rata-rata yaitu 8,33 mm. Penelitian ini membuktikan bahwa hasil metabolit sekunder daun mangrove api-api yang dikstrak menggunakan ethanol memiliki senyawa aktif  yang bersifat antibakteri  terhadap staphylococcus epidermidis.
