Abstract

Getah buah papaya diambil dan diisolasi enzim papain kemudian ditambahkan dalam proses pengolahan daging kerang darah baik dengan cara direbus maupun dikukus dan sebagai pembandingnya dilakukan hal yang sama untuk daging kerang darah baik di rebus dan dikukus tanpa penambahan enzim papain hasil isolasi tersebut. Dilakukan Uji  kualitas kimia daging kerang darah  (Anadara granosa) hasil olahan melalui analisis proksimat dan analisis asam lemak. Hasil penelitian menunjukkan berat molekul dari enzim papain yang diisolasi dari  Getah buah papaya adalah 21 kDa. Komposisi proksimat yang terbaik dibandingkan dengan kontrol (tanpa penambahan enzim papain) adalah pengolahan dengan penambahan enzim dimana pengolahan direbus dengan penambahan enzim diperoleh pH 6.757, Kadar air 68.21, kadar lemak 5.66598, dan kadar abu 1.78764 sedangkan dengan dikukus  diperoleh pH 6.437, Kadar air 59.29,   kadar lemak 4.22242, dan  kadar abu 2.35173. Kadar protein dan nilai susut masak tertinggi berturut-turut pada perlakuan penambahan enzim papain sebesar 67 % dan 50.94   sedangkan  terendah pada perlakuan tanpa penambahan enzim papain sebesar 18 %  dan 40.18. Hasil analisis asam lemak dengan metode GC-MS menunjukkan bahwa kerang darah tanpa penambahan enzim mengandung 6 jenis asam lemak yaitu metil ester asam meristat (4.15%), metil ester asam palmitoleat (8,81%), metil ester asam palmitat (19.24%), metil ester asam oleat (3.43%) metil ester asam stearat (14.09%) dan metil ester arakidonat (5.19%) sedangkan  kerang darah dengan penambahan enzim mengandung 7 jenis asam lemak yaitu metil ester asam meristat (5,25%), metil ester asam palmitoleat (9.62%), metil ester asam palmitat (21.54%), metil ester asam oleat cis (3.97%), metil ester asam oleat trans (4.20%),  metil ester asam stearat (13.33%) dan metil ester arakidonat (5.15%).

Abstract

Analysis of histamine content in processed bullet tuna (Auxis thazard) stew flesh can be carried out by Spectrophotometry method, using p- phenildiazonium sulfonate reagent. A qualitative, visual comparison of colour intensity of samples with reference colour scale of the standard solution concentration can be used to determine levels of histamine without the aid of a spectrophotometer. The histamine content is determined quantitatively by the standard curve regression equation (y= 0.003x–0.062) with determination coefficient value (R2= 0.938). The results showed that histamine content inprocessed bullet tuna (Auxis thazard) obtained: 46.9964; 40.3093; 34.4348; 28.9900 and 24.8862 mg/100g fish, at 0.5; 1.0; 1.5; 2.0 and 2.5% concentration of NaCl, respectively.

Abstract

An extraction of chitin from shell of the tiger shrimp (Penaeus monodon), a convertion chitin into chitosan and depolymerization chitosan into oligochitosan using hydrogen peroxide based on variations in heating temperature have been done. Chitosan had depolymerized and it’s molecular weight had tested by end group analysis method and it’s degree of deacetylation had tested by UV-Vis spectrophotometry method. Oligochitosan had obtained from the conversion of chitin is isolated from the shell of tiger shrimp and from commercial chitin. The content of chitin obtained in tiger shrimp shells was 35.90% while the result of the conversion of commercial chitin into chitosan amounted to 62.33%. Characterization of functional groups using FTIR spectrophotometry showed that the conversion of chitosan from chitin commercial have absorption bands of 3617.56 (OH), 3050.47 - 3127.63 (-NH stretching), 2894.24 (-CH methylene), 1679.06 (-C = O), 1564.30 (-NH bending), and 1076.30 cm-1 (-CO-). The commercial chitosan which is characterized by FTIR spectrophotometric method also supports the results of the conversion of chitosan from chitin commercial. In the process of depolymerization of chitosan by hydrogen peroxide was found that the greater heating temperature was used, the smaller the percent yield and molecular weight of oligochitosan were at 40 oC, 50 oC, 60 oC and 70 oC gained weight average molecular oligochitosan were 1030.12 g/mol, 1019, 28 g/mol, 978.12 g/mol, and 908.82 g/mol, respectively

Abstract

Microalgae are photosynthetic microorganisms that are widely distributed in waters. They have the potential as an alternative source of pigments, lipids, proteins, and carbohydrates. In this study, identification and isolation of single-cell microalgae from Ambon Bay were carried out by serial dilution method and inoculation of the culture by appearance/spread on the surface of the solidified agar medium. The results showed that the waters of Ambon Bay have physical parameters such as temperature, pH, salinity, and TDS, which are still within the threshold specified in the seawater quality standard for biota. The water conditions at the 10 sampling locations had different salinity, pH, temperature, and TDS. This condition affects the distribution of microalgae in the waters in Ambon Bay. The image from light microscopy shows that there are 27 species of microalgae scattered in the waters of Ambon Bay, which belong to the classes Chlorophyceae, Flagilariophyceae, Bacillariophyceae (diatoms), Coscinodiscophyceae, and Dinophyceae. Microalgae isolation obtained five species (single-cell) including four species from the class Bacillariophyta (Navicula sp, Nitzschia sp, Cyclotella sp) and one species from the class Chlorophyta (Chlorella sp).

Abstract

In Maluku, nutmeg and mace are considered valuable market commodities, while the pod are wasted andleft in the field. The research aimed to expand and to characterize the quality of the nutmeg-pod oil by someprocess technology (methods of drying and distillation). Drying of sliced nutmeg pod either under shade, in thesun, or using cabinet dryer were carried out followed by distillation process either using water distillation orwater-steam distillation. Physical characteristics (refraction index and solubility in 90% alcohol), myristicincompound and oil yields of the essential oil resulted from those process combinations were analyzed. Resultindicated that the highest yield was obtained (1.65 g) from the combination of drying under shade and watersteam distillation. The refraction index and solubility in 90% ethanol of the extracted oils were all in the rangeof the SNI Quality Standard. There were about 21 different components in the oil of nutmeg pod. The level ofmyristicin (the valuable component) was much higher than that found in the nutmeg.

Abstract

Microalgae are photosynthetic microorganisms that contain carbohydrates can be converted into glucose through a hydrolysis process so that they can be used as raw materials for bioethanol production. Navicula sp. strain TAD is a type of marine microalgae that is spread in the inner Ambon Bay (TAD) sea waters and is used to manufacture bioethanol. This study aims to determine the content of carbohydrates and bioethanol produced from tropical marine microalgae Ambon bay Navicula sp. strain TAD. The research was conducted through several stages, namely the cultivation of Navicula sp. strain TAD to obtain biomass, determine carbohydrate content in biomass, hydrolyze biomass and manufacture bioethanol through a fermentation process using Saccharomyces cerevisiae. The results showed that Navicula sp. strain TAD cultivation for seven days had the highest cell density of 72.167 × 105 ± 0.946 cells mL-1 with dry biomass of 0.933 ± 0.062 g and productivity of 0.166 ± 0.011 gL-1 hour-1. The sulfuric acid hydrolysis process was analyzed for a sugar content of 146.5695 ± 0.758 mg. A fermentation process follows the results of the hydrolysis to produce bioethanol. The bioethanol content obtained was 6.357%. These indicated that Navicula sp. strain TAD has the potential to produce bioethanol
