The study aims at quantifying trade scale of some economically wild birds and describing captured trends which have been practised by wild bird catchers. The study was conducted in Tanah Grogot, Paser District, East Kalimantan Province, from September to December 2008, by surveying wild bird market and interviewing catchers and sellers. We measured two main attributes of market dynamics; first, each species availability in the market as the percentage of market days sampled where the species appeared; second, daily abundance of a species as the monthly average number of each bird per day for all days sampled. Seven wild bird species that have been traded commodities for years were White-rumped Shama Copsychus malabaricus (25.41%; 602.25+70.79 individuals per month), Yellow-vented Bulbul Pycnonotus goiavier (11.47%; 111.25+12.50 individuals per month), Crested Myna Acridotheres cristatellus (12.30%; 73.25+10.44 individuals per month), Spotted Dove Streptopelia chinensis (5.73%; 22.00+12.83 individuals per month), Hill Myna Gracula religiosa (12.30%;12.00+0.82 individuals per month), Greater Green Leafbird Chloropsis sonneratii (7.38%; 11.75+2.50 individuals per month) and Magpie Robin Copsychus saularis (6.56%; 8.75+1.71 individualsper month). Specific capture location within Paser District could reflect distribution and habitat preference of each bird species.

Publisher : Research Center for Biology-Indonesian Institute of Sciences

A total of 27 soybean {Glycine max (L.) Merrill} genotypes including check variety (Kawi) were evaluated on dry land at Ngale Experimental Farm, Ngawi, East Java during early rainy season of 2009/2010. The experiment was conducted in a randomized complete block design with three replications. Plot size was 4 m x 5 m, plant spacing was 40cmx20cm, each hill contained two plants. A correlation and path coefficient analyses were used in order to determine the association among characters and quantify the direct and indirect effects of agronomic traits on seed yield. The study has identified 3 varieties, i.e. Kaba, Wilis and Tanggamus produced the highest yield (>1.6 t/ha) and had good adaptation on dry land. Two varieties (Grobogan and Argomulyo) having large seed size (>15 g/100 seeds), and four varieties,i.e. Tidar, Grobogan, Gepak Ijo and SHR-W60 had early maturity (81days). Therefore, these varieties can be used as source of parents on breeding program. Among the agronomic characters, plant height, number of pods per plant and harvest index were positively and significantly correlated with grain yield. The direct effect of plant height, number of pods per plant and harvest index to grain yield as indicated by path coefficient were the highest, while other causal effects to grain yield were small or negative. Based on both analyses, soybean genotypes with high grain yield should have sufficient plant height, high number of pods per plant and high harvest index. Therefore, plant height, number of pods per plant and harvest index can be suggested for selection criteria in selecting high yield soybean genotypes on dry land.

In order to develop yeast Candida tropicalis as a model cell for evaluation of substance having anti- or pro-oxidant activity in cell level, the effect of hot water tea {Camellia sinensis (LJ Kuntze) extract on peroxidized lipids, a marker of oxidative stress and cell mortality in the yeast caused by paracetamol has been evaluated. Incubation of yeast cell in the presence of 1.38 % green tea for 2 h decreased cell viability followed with increasing of peroxidized lipids, whereas 0.27 % green tea caused increasing of peroxidized lipids without causing cell death.Yeast cell was not affected by 0.1 % green tea. Incubation of yeast cell with presence of 0.15 % (g/v) paracetamol for 2 h did not cause cell mortality, however content of peroxidized lipids increased significantly. In the presence of higher dose of paracetamol (0.3 %) cell viability remarkably decreased and followed with increasing of peroxidized lipids significantly. Green tea of 0.1 % increased cell viability of cells treated with 0.3 % paracetamol while peroxidised lipids decreased. The data indicated that high dose of paracetamol caused oxidative stress in yeast cells, while green tea with lower concentration might protect paracetamol toxicity due to its antioxidant property. Although the antioxidant property, high dose of green tea could cause oxidation due to its pro-oxidant activity. In conclusion, yeast C. tropicalis could be potentially used as a model cell to evaluate substances having antioxidant property in cell level.

N-acetyl-D-glucosamine (GlcNAc), the monomeric unit of polymer chitin has attracted much attention for their therapeutic activity in osteoarthritis.It is mainly produced by acid hydrolysis of chitin which affect the environmental problem because of its acidic wastes.Therefore, it is need to develop the new method for GlcNAc production. The aim of this experiment is to produce GlcNAc by mean of submerged fermentation of chitin. The preliminary study showed that fermentation of chitin by Aspergillus sp.501 produced higher GlcNAc than that of Saccharomyces sp. It was 1.39 ng/ml and 1.07 ng/ml. Then the Aspergillus sp. 501 was used in optimation of GlcNAc production. The effect of pH and nitrogen course such as bacto peptone, yeast extract, amonium sulfat and urea to GlcNAc production was examined. Then the product of GlcNAc was precipited by vacum evapotated and freeze dryed. The results showed that the highest of production GlcNAc of 2.228 ng/mL was obtained on pH 4 of medium solid state fermentation using urea as Nitrogen source at 10 days incubation.

Salmonella enteritidis is one of pathogenic bacteria in chicken and human with re-emerging foodbome pathogen. Uncontrol use of antimicrobial drugs for the prevention and treatment of infectious diseases in chicken and human may lead to the development of antimicrobial resistance. Sampels of chicken eggs were collected from markets, layer farms, and grant parent stock farms. Sampels from human were anal swabs collected from hospitals and a laboratory of microbiology. Identification of bacteria was conducted by isolation and biotyping using selected media for Salmonella, while serotyping S. enteritidis was conducted with spesific 0 somatic (1, 9, and 12) and H flageIJa (m) antigen.Antimicrobial resistance tests were conducted by the standard diffusion method using antimicrobial disks.The results of isolation and identification of Salmonella show that 9 out of 122 (7.4%) sampels of layer eggs and 7 out of 23 (30.4%) sampels of embrioneted eggs were positive with Salmonella spp. The results of serotyping against S. enteritidis show that 7 out of 9 (77.0%) from layer eggs and 7 out of 7 (100.0%) from embrioneted eggs were positive with S. enteritidis.From the IS anal swabs of human were obtained 14 (93,3%) contain S. enteritidis.The antimicrobial resistance profiles of S. enteritidis isolated from layer eggs show high resistances to streptomycin (42.9%), neomycin (85.7%), doxicycline (64.3%), and ciprofloxacin (57,1%), whereas those S. enteritidis isolated from human show high resistances to streptomycin (50.0%), neomicyn (85.7%), tetracycline (42.9%), and doxicycline (42.9%).Multiple resistance profiles of S. enteritidis isolated from eggs were mostly to 2-3 antibiotics and those of S. enteritidis isolated from human were mostly to more than 5 antibiotics.

Flowering in jatropha (Jatropha curcas L.) was considered as one of major factors that contribute to its productivity. Small number of female flowers produced in each inflorescence was believed as the main cause of low seed production.Introduction of Hd3a flowering gene driven by rol C promoter was supposed to improve total number of flowers including female flower.The objective of this research was to optimize cell proliferation and regeneration medium in Jatropha transformation method mediated by Agrobacterium, to obtain transgenic Jatropha containing Hd3a flowering gene as well as to understand the effect of this transgene on jatropha flowering character.Callus induction medium containing 0.5 mg/1 IBA added with 3 g/1 PVP produced the highest frequency of shoot formation.We obtained 26.67% to 33.33% putative transgenic plantlets that were able to grow in 40mg/l hygromycin selection medium. PCR analysis revealed that seven out of 10 putative transgenic plantlets were positively transgenic.Extremely early flowering character that was confirmed by histological analysis was also shown by some transgenic plantlets.
