Abstract

ABSTRACTGenetic Variation of Monascus purpureus Isolated from Chinese Red Rice. An attempt was carried out to detect genetic variation among six Monascus purpureus isolates by RAPD finger printing. The isolates studied were isolated from Chinese red rice (ang-kak) collected from Indonesian markets. Seven types of oligonucleotide 12-mer primers were used in this study. These primers were different from G+C ratio (42%, 50%, 68% and 75%) so as to know the best ratio for DNA amplication. Products of DNA amplication by seven primers were observed such as 158 banding patterns, comprise of 23 common fragments and 135 polimorfic fragments. The result showed that the six isolates were divided into two groups based on DNA banding patterns. The same grouping was also shown by phylogenetic analysis. This analysis indicated two cluster which were different from its genetic distance (49%) and two pairs of isolates were identical to each other. So far, this RAPD analysis proved that there was high genetic variation within the six isolat of M. purpureus. It was assumed that there was a tendency of species separation within those isolates. It is suggested that sequencing analysis on 18S rDNA should be carried out to ensure status of M.purpureus species used in ang-kak production.Key words: Monascus purpureus, variation, genetic, Chinese red-rice, RAPD

Abstract

Frogs communities of degraded areas in Curug Nangka area, West Java. A Total of thirteenfrog species were found in degraded land areas of Curug Nangka, on the foot hills of MountSalak at elevation of 640 m - 730 m above sea level (asl). In the fast-flowing river habitat, threefrog species dominated this habitat, they were Huia masonii, Hylarana chalconota andOdorrana hosii; whereas in fast-flowing ditch habitat, Phrynoidis aspera and H. chalconotawere the dominant species, and for the pine plantation, H. chalconota and H. nicobariensisdominated this habitat. On the river transect, the presence of individuals H. masonii wasinfluenced by the dynamics of air temperature and water temperature. In the open ditchtransects, the presence of individual P. aspera was influenced by water temperature. Therewas a stronger positive association between the presence of individuals H. masonii andindividuals of O. hosii than between individual O. hosii and H. chalconota on the rivertransect. Among individuals of H. masonii and individuals of H. chalconota there was apositive association; however in the open ditch transects, there was no association betweenthe presence P. aspera and H. chalconota. The presence of H. chalconota and H. nicobariensison the pine plantation transect had strong positive association.Keywords: frog community, degraded area.

Abstract

The animal obtains energy from foods. Apparent Metabolizable Energy (AME) is used to determine metabolizableenergy value of bird’s food. The objective of this research was to evaluate Apparent Metabolizable Energy (AME)value in Blue-crowned hanging parrot (Loriculus galgulus L., 1758), fed with corn mashes, oat mashes, dan pollardmashes. This research consisted of two experiments, which were 1 week of preliminary study and 8 weeks of datacollection. Studies were carried out with six Blue-crowned hanging parrots, two males and four females. The birdswere kept individually in metabolism cage (70 x 43 x 52 cm). The birds were treated with 3 different energy sources,corn-based diet (P1), oat-based diet (P2), and pollard-based diet (P3). The diets were then offered to the birds adlibitum in the form of mashes. Variables observed include dry matter consumption and Apparent MetabolizableEnergy (AME) value. From the calculation, AME of birds that fed with pollard mashes was higher compared to cornand oat mashes as well. In P1, AME value of birds was 43.64 cal/g with 93.90% of metabolic efficiency. While, inthe P2 and P3, AME value were 43.86 cal/g and 39.07 cal/g with number of metabolic efficiency 91.75% and94,58% respectively.Keywords: nutrition, pollard, oat, corn, AME, metabolic efficiency

Abstract

ABSTRACTSeren Taun Ceremony at Cigugur, Kuningan District, West Jawa: TraditionalCeremonial For Environment Conservation. Human being couldn’t be separatedfrom the environment, but in reality the damage of the land is precisely caused by humanbehavior. The reason of this is that people don’t have good relationship with the surroundingenvironment. Following this logic, with participatory observation I have done it in February4 until 15th, 2004, the indigenous people with their tradition have their own way toconserve the land. They have a ritual tradition that can be used as a means of educationfor their adherent. Furthermore, ritual traditions also show the nearness of emotionalrelationship between human and the environment.Keywords: environtment, ritual tradition, Cigugur Kuningan

Abstract

ABSTRACTThe objective of study was to isolate, identify and characterize the CMC-ase producing yeast from South East Sulawesi, Indonesia.  We isolated 142 strains and obtain 53 strains (37.32%) were CMC-ase producer consist of 26 species residing within 10 genera.  Candida was the most diverse genus consisting of 15 species. It is important to note that several strains residing within this genus could be candidate for new taxa, among others Candida aff. cylindracea PL2W1, Candida aff. insectorum PL3W6, Candida aff. friedrichii  MKL7W3, Candida aff. lessepsii, Candida aff. tenuis.  Five new candidates for novel species of cellulolytic yeast close to Yamadazyma mexicana: were Yamadazyma aff. mexicana (5 strains). Pichia, Pseudozyma, Sporodiobolus, and Sporobolomyces were other cellulolytic yeasts found in South East Sulawesi.  It is obvious, that leaf litter was a good source for cellulolytic yeasts. This CMC-ase producing yeasts dominate this biome, and production of extracellular cellulase is critical strategy for such yeast to survive in cellulose rich ecosystem such as leaf-litter.  This finding would suggest that yeasts play key role on hydrolyzes of cellulose and important resources for sustainable energy research. Keywords: cellulolytic yeasts, secondary forest, South East Sulawesi, leaf-litter

Abstract

Ethnobotany Contributes to The Understanding Human Relationship with Plant and TheirEnvironment. The scope of ethnobotanical research has been developed to a broader scopefrom the originated word of ethnobotany was coined.. This discipline attempts to explainreciprocal relationships which occur between local societies and its natural world, in extant,between local societies and their cultures that reflected in the archeological records.Ethnobotany is also very closely related to the domestication of plants such as the speciesdomesticated, where these species domesticated, the purpose of domestication, the manner,and the status of the domesticated plants today. Etnobothany also concerns to the role ofplants in ecology, environment and phytogeography as conceived by tradition or by the localcommunities. In addition to its traditional role in economic botany and the exploration ofhuman cognition, ethnobotanical research has been applied to the practical areas such asbiodiversity prospecting and vegetation management. Thus ideally, ethnobotany shouldincludes rules and categorization acknowledged by local communities. Rules and categorizationare use to appropriately facing daily social situations in recognizing, interpreting and utilizingplant resources in their environment. In summary, the scope of research in ethnobotany isinterdisciplinary and ethnoscience as mentioned earlier and these scopes will be the mainfocus of discussion in this article. In particular, in its relation to the strategic position ofIndonesia based on wealth, diversity of plants, species and ecosystems and socio-culturallife.Key Words: Ethnobotany, Localknowledge, Wisdom

Abstract

Freycinetia Gaudich. is a climber plant belongs to the family of Pandanaceae. Seven species of Freycinetia from Mount of Nyiut and Palung located in West Kalimantan have been recognized based on leaf anatomy. Paradermal and transversal leaf sections of those species were observed, and the data was used to construct a dendrogram using Jaccard similarity index  and Unweighted Pair Group Method with Arithmetic Average (UPGMA) method. Six main characters have been used to distingush and evaluate the similarity between its, i.e. number of hypodermal layers, number of palisade layers, shape of sponge tissue, layout of sclerenchyma tissue, stomata size,  presence of costal and intercostal cells, and shape of vascular bundle. Cluster analysis based on the anatomical data showed that seven Freycinetia species were clustered into two major groups at similarity coefficient 0.38. The first group consisted of F. angustifolia,   F. imbricata, F. sarawakensis, and F. winkleriana, while the second group consisted of F. corneri, F. sessiliflora and F. sumatrana. Keywords: Anatomical variation, Freycinetia, West Kalimantan
