Abstract

Vegetable oil can be produced from a perennial plant such as coconut (Cocos nucifera L.). There are few techniques for coconut oil extraction, such as physical, chemical, and fermentative processes. The fermentation process uses microbial inoculum as starter. Ground coconut meat was soaked in warm water, than squeezed several times to get coconut milk. After being allowed to stand for 4-5 hours, it separated into two layers, cream and skim. Starter was prepared from a mixture of milk and coconut water (1:9, v/v) which enriched with 2% tomato extract, 0.5% urea, and 1.0% molasses and then preincubated for 5 days under agitation. Starter with different concentration (1.0; 2.5; 5.0; and 10%) were added onto coconut milk and allowed to be fermented for over night. The extracting oil was analyzed for further experiment, especially, on its antibacterial activity. The maximum yield of 23% was achieved by using 2.5% starter. Total protein, fat, FFA, and cholesterol content of the fermented coconut oil were 0.05%, 96.45%, 0.29%, and 0.008%, respectively. The gas chromatogram showed that this oil contained high lauric acid (46.20%), and 13.94% miristic, 5.97% palmitic, 9.00% palmitoleic, and 19.73% stearic acid, respectively.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: coconut oil, fermentation, antibacterial activity, biochemistry analysis.

Abstract

Amorphophallus titanum Becc. (Araceae), is known by titan arum (western) or bunga bangkai (Indonesian), is the bulkiest inflorescence in the world. The species is valued for its unique character of their inflorescence. The species has been overexploited and is considered as vulnerable plant species. The present study is carried out to assess genetic diversity and to estimate genetic relationship among 22 accessions collected from two different populations in Sumatra using Random Amplified Polymorphic DNA (RAPD). Nine RAPD primers generated 143 scorable bands which 137 (95.84%) of them were polymorphic. Clustering analysis was performed based on RAPD profiles using the UPGMA method. The range of genetic dissimilarity value among accessions was from 0.14 to 0.59, while the range of genetic dissimilarity among populations was from 0.67 and 0.77. These values showed that A. titanum from Sumatra were more genetically diverse among genotypes than that of among populations.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Amorphophallus titanum Becc. random amplified polymorphic DNA.

Abstract

RAPD-PCR method and isozyme analysis were used to obtain information of genetic relationship among cucumber varieties. Such information is urgently utilized to support plant breeding program of cucumber. Research was done at the Biotechnology Laboratory of Plant Pest and Diseases, Faculty of Agriculture of Brawijaya University, Malang and Molecular Biology Laboratory, Faculty of Matemathic and Natural Sciences of Brawijaya University, Malang. DNA isolation was done using CTAB method by additional NaCl modification. Sixteen primers from operon were employed to amplify DNA genome by RAPD-PCR. Two enzymes, Esterase and AAT were chosen for isozyme analysis. Clad 97 Program was used for analyzing the data and results in data grouping based on proximity value. Cluster analysis based on isozyme data indicated that there was an adequate lower genetic variation in cucumber, where seven of nine tested varieties showed proximity value of 1.00. Eleven of sixteen primers in RAPD-PCR analysis produced DNA bands. Relativity analysis by using RAPD-PCR method showed high enough of genetic variation. Relativity analysis by using both methods showed that variety 07 was the furthermost. The proximity value between varieties 01 and 02 was 0.916667, these varieties have the higest proximity value among allvarieties.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Cucumis sativus L., RAPD-PCR, isozyme.

Abstract

Starch of ganyong is one of the sources of ethanol which is able to be produced by acid hydrolysis and fermentation process. It had high concentration of carbohydrate that is 80%, so it could produce glucose highly within acid hydrolysis process. The result showed that the optimal amount of reducing sugar had been produced by nitrate acid 7% (dextrose equivalent, DE = 28.4). Nevertheless, type and concentration of acid had no significantly correlation to reducing sugar yielded. The total amount of glucose had correlation to amount of ethanol, in fermentation process. The optimal amount of ethanol was yielded from 4.81% of glucose and it produced about 4.84% ethanol. The more amount of glucose was yielded the more ethanol was produced. Controlling pH every 12 hours did not affected to production of ethanol significantly.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: bioethanol, Canna edulis Ker, acid hydrolysis, fermentation.

Abstract

The objective of this study was to found on composition and structure of vegetation of upstream Cianjur Watersheds at the montane zone Mt. Gede Pangrango National Park. Research sampling conducted by using plot method placed purposive random sampling at research location with increase elevation equal to 300 m from sea level. Every 300 m elevation level, were taken 10 sample plots so that up to 1600- 2400 (montane zone) totalize plot were 30. Measured parameter cover density, frequency, dominancy, Important Value Index (IVI), Diversity Index (H'), and Evenness (E). The subdividing pattern plot had been done through cluster analysis. Result of research indicatethat species puspa (Schima wallichii) and rasamala (Altingia excelsa) were two species with highest Important Value Index, so that both species considered to be dominant the community. The species diversity index (H’) equal to 3.78 categorized to high, but the evenness value (E) was categorized to low (1.26). The phenomena happened because the distribution of species was heterogeneous. The Cluster Analysis indicated that there were three sub-groups which can be categorized as sub-zone in sub-montane zone were the sub-zone lower, middle and high.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: structure and composition, vegetation, montane zone, Mt.
