Abstract

ABSTRACTFoxtail millet [Setaria italica (L.) Beauv.] is one of potential cereal plants that can be developed as a source of carbohydrates in marginal and dry lands. The purpose of this study was to examine the tolerance to drought of foxtail millet accession of Buru Merah as a result of gamma radiation treatment. In this study, the seeds of the Buru Merah accession were treated with gamma ray at doses of 0, 25, 50, 100 and 200 Gy. The established growing plants were then treated with different intervals of watering, which were every day (as control), 2 days, 4 days, and 6 days which were arranged in factorial randomized block design with three replications. The observed variables were increase plant height, increase of leaf number, leaf chlorophyll content, plant water potential and  yields. The results revealed that the radiation treatment did not show any significant difference in the production of plant biomass. With radiation treatments of 0, 25, 50 and 100 Gy. and a two-day watering interval the plants can still maintain its water potential above -3 MPa and showing optimum growth. However radiation treatment resulted a significant difference in panicle production, especially between the radiation dose of 200 Gy. and others. The combination of 0-100 Gy. radiation treatment and 2-day watering interval produced plants with optimum panicle production.Keywords: drought, growth, millet, production, radiation, tolerant

Abstract

In Indonesia, data on the phenotype of AI virus subtype H5N1 is very limited, due to the facilities for such testingshould be performed in a laboratory Biosafety level III. Additionally influenza virus has a high error rate duringtranscription of their genome has low RNA polymerase. High error rates generate quasispecies. In this study, wedid some H5N1 viruses infection with different genetic variations and conducted DNA sequencing in severalorgans. To determine the possible emergence detection of quasispecies in different organs and until the virus wasexcreted. We tested the hypothesis that the quasispecies might arise from virus that was infected to theexperimental animals. The results of this study showed that the AI virus subtype H5N1 had different phenotypes inanimal depending on their genetic character. AI virus subtype H5N1 killed chickens within 48-72 hoursdepending on the genetic character of the virus. New AI viruses of subtype H5N1 caused more severe organdamage severe than the character of the old AI viruses. Adaptation of virus in each organ also proved that the viruslikely create variations/quasispecies, which was different from the viral origin.Keywords: Phenotypes, avian influenza, H5N1, genetic character, quasispecies

Abstract

ABSTRACTStudy on the relationships between vegetation coverage and bird distribution in Moti Island,Ternate, North Moluccas. Research study on relationships between vegetation coverage andbird distribution in Moti Island, Ternate, Moluccas was conducted on May 2010. The objectiveof this research is to understand the bird species occurrence on a vegetation type as anindicator for environment quality determination in small Moti Island. Data on the occurrenceof bird species in the every vegetation type was collected and recorded using explorationmethod. The bird species were identified for the scientific name, local name, their activities,location or coordinate position and their vegetation or habitat. The data then compiled andtabulated for the spatial analyses using Ikonos image and topographic (SRTM) maps data.The data output from the spatial analyses then analyzed using Principle Component Analyses(PCA) to get the most important factors of vegetation cover types that influenced the occurrenceof the bird species. The results showed that about 34 bird species, belong to 20 families and 29genera have occurred in the Moti Island. About 13 vegetation types were recorded as naturalsites of bird species for feeding, playing and breeding grounds. Analyzing data using PCAshowed that at least 3 vegetation types have played as important sites for bird species in thisarea. The sites were mangrove, secondary forest and mixed gardens. The roles of both threeimportant vegetation types and bird species as environment quality indicators were in detaildiscussed in this paper. The discussion also includes how to develop fisherman villages inMoti Island using its own natural resources and biodiversity.Key words: Moti Island, birds distribution, vegetation coverage, spatial analyses

Abstract

The aims of this study was to isolate and select Bacillus from the gut of catfish as probiotic candidates in the fish feed production. Isolation was conducted by heating samples at 80 °C for 10-15 minutes using Triptone Soy Agar (TSA) media which have been added with 1% skim milk for proteolytic activity and 1% starch for amylolytic activity. Selection was conducted based on pathogenicity test, antibiotic susceptibility test and total suspended solids. Isolate that have ability to degrade feed would be made the growth curves, analysis of protease and amilase activites and also combination of bacteria isolate with feed. Selected isolates as candidate probiotic were identified furthermore using 6S-rRNA gene. Among 16 isolates, there were 7 isolates that have gamma hemolytic activity (PTB 1.1, PTB 1.2, PTB 1.4, PTB 1.7, STB 1.6, STB 1.1 and STB 2.1). Antibiotic susceptibility test showed that 3 isolates were sensitive to the tested antibiotics (PTB 1.4, PTB 1.7 and STB 1.6). These three selected isolates were tested for their ability to degrade fish feed. PTB 1.4 isolate was able to degrade the feed with the smallest residue on the filter paper (0.0068 g). PTB 1.4 isolate also has proteolytic and amylolytic index of 0.61 and 0.60, respectively. Amylase activity of PTB 1.4 isolate added with 1.2% feed reached the highest peak in 120-hour of observation time (0.399 µ/mL) and the highest protease activity was in 72-hour of observation time (6.595  µ/mL). PTB 1.4 isolate has the ability to degrade the feed with the amount of 106 CFU/mL inoculum. Based on 16S-rRNA gene sequences isolate PTB 1.4 was 99% homolog with Bacillus megaterium. Isolation and selection of probiotic candidate from Clarias sp. get PTB 1.4 was a best isolate that there were not pathogenic, sensitive to antibiotic test, had protease and amilase activities. PTB 1.4 isolate had capability to degrade the feed. Keywords: Bacillus, Clarias sp., probiotic, feed
