Abstract

ABSTRACTThe Screening of Isolated Rhizobium from Wamena on Weki in Green House Condition. The green house experiment has been carried out to study the effectiveness of some Rhizobium isolates on the growth of weki (Paraserianthes falcataria) seedlings. Thirteen isolates of Rhizobium viz. 1wy(1), 1wy(2), 1wy(3), 2wy(4), 3wy(1), 3wy(2), 4wy(1), 5wy(1), 6wy(1), 7wy(1), 9wy(1), 10wy(3) and 11wy(1) have been screened and inoculated to the plant seedlings. The purpose of the study was to find out whether the Rhizobium isolates able to stimulate and improve the growth of weki seedlings. The results showed that all of the Rhizobium isolates could stimulate the production of the root nodules . However each isolate was difference effect on the plant growth. Isolate number 11 wy(1) could stimulate all the plant growth parameters significantly.Key words: Screening, seedling, Paraserianthes falcataria, weki, green house, Rhizobium.

Abstract

ABSTRACTStatus of avian influenza virus subtype H5N1 in Indonesia until 2014 is still endemic in poultry and recorded, there were two types clade of circulating H5N1 namely clade 2.1.3 and the new introduction of lade 2.3.2 since the end of 2012. Both of the clade of avian influenza viruses subtype H5N1 (clade 2.1.3 and 2.3.2) caused the the  AI vaccination program to control of AI in poultry needs to be evaluated.  In this study, we developed a bivalent AI vaccine (which contains clade 2.1.3 and 2.3.2 viruses as a seed vaccine) that   adapted with  the circulation of AI viruses in the field. Result of the study showed that the bivalent vaccine which developed in this study has good efficacy that was challanged with both of AI clade AI and proven to reduce shedding / viral contamination to the environment. It is expected that  the development of bivalent H5N1 vaccine will increase the effectiveness and efficacy of vaccination programs to control highly pathogenic avian influenza disease in Indonesia. Keywords : avian influenza virus, clade, vaccine, bivalent

Abstract

ABSTRACTSexual Dimorphism, Reproduction and Prey of Long Tailed Lizard Takydromus sexlineatusDaudin, 1802 (Lacertilia :Lacertidae). The morphology and reproductive biology of Takydromussexlineatus were studied in Bogor. Males are larger than females. There is sexual dimorphism onhead size and tail length (larger and longer tail on males) of body size among sexually matureadults, apparently as a consequence of sexual selection. The diet of T. sexlineatus consists ofvariety of insects and their larvae, arachnids, decapods and snails. Most of the diet are insect(more than 70 % for adults and juveniles). There are higher prey competitions at adult skinksbetween males and females, adult females and juveniles, but not between adult males andjuveniles. The length of adult males and females are 44.6 - 58.1 mm and 49.6 - 62.3 mm respectively,lay eggs throughout the year with 2 -3 clutches, per clutch consists of 1 - 3 eggs.Key words: Lizard, Takydromus, Ecology, Sexual Dimorphism, Prey, Reproduction, Bogor, Indonesia

ABSTRACTDigestibility and Feed Emciency of Flying Squirrel (Petaurus breviceps) in Captivity.Two male flying squirrel (Petaurus breviceps) were used in this experiment to observe feedintake, digestibility and feed efficiency of them. The animals were given alternative diets incaptivity, namely passion fruit, sweet corn, banana, guava, papaya, coconut, sun flower bean,bread, and dogfood. The result showed that average intake of ash, crude protein, ether extract,crude fiber, nitrogen free extract, and gross energy were 2.4%, 2.3%, 9.3%, 6.0%, 69.9%, and4.0 kkallg respectively. The nutrient digestibility coefficient ash, crude protein, ether extract,crude fiber, and nitrogen free extract were 33.6%, 73.5%, 96.2%, 60.9%, and 95,5%respectively. Average body weight gain is 0.35 g/head/week and feed efficiency is 0,4%. Thepreferred feed is bread (58%), sweet corn (l2%), and coconut (1 1 %).Key words: Digestibility, consumption, feed efficiency, Petaurus breviceps

Abstract

ABSTRACTInformation on genetic diversity of fermentative yeast which produce ethanol is very crucial in developing biofuel production in Indonesia. Research on ethanol producing yeasts is interest of many scientist. The objective of study was to reveal yeast diversity in Indonesian fermented foods that able to produce ethanol. The sample of fermented foods were collected in the traditional market in Karimun Besar Island, Kepulauan Riau. Yeast isolation was performed using serial dilution with direct plating and enrichment culture with glucose as carbon source. Fifteen of isolates were isolated and identified by amplification of D1/D2 region LSU 26S rDNA. Its ethanol production characteristic was analyzed base on fermentation activity and measurement with gas chromatography for ethanol content. The result revealed that 8 yeast species were found belong to Ascomycetous and grouped into 5 clades which are able to produce ethanol. The highest ethanol production was obtained by Saccharomyces cerevisiae Y15Kr107 (3.53%) followed by Torulaspora delbrueckii Y15Kr104 (1.63%), Saccharomyces cerevisiae Y15Kr093 (1.58%), Candida glabrata Y15Kr110 (1.4%), Torulaspora delbrueckii Y15Kr103 (1.29%), Candida glabrata Y15Kr108 (1%), Torulaspora globosa Y15Kr094 (0.92%), Kodamaea ohmeri Y15Kr096 (0.61%), and Pichia kudriavsevii Y15Kr106 (0.31%) Y15Kr105 (0.21%) Y15Kr109 (0.16%). Other yeasts strains did not produce ethanol but may play different role in fermentation process.Key words: yeast, fermented food, ethanol, Kepulauan Riau

Abstract

ABSTRACTSpatial Modelling Impact for Sumatran Serow Occupancy [Capricornissumatmensissumatraensis (Bechsteiu, 1799)] at Sipurak-Kerinci Seblat National Park, Jambi.Existency for habitat preference of sumatran serow is very important to support the wildlifemanagement. The research was designed to study the influence of factor of spatialhabitat occupany or habitat preference of sumatran serow [Copricornis sumatraensisAbstractsumotraensis (Bechstein, 1799)l. The detection-non detection survey method was appliedfor observation. Data processed by using software Arcview 3.2, and PRESENCE PC.From the ten model selected, there was little variation in the estimates of occupancy (Y )IPA0 (ranging from 0,7283 to 0,7637) and detection probability orp (0,2407 to 0,2495).The top two ranked models are distance to forest and slope. It's mean th%t distance toforest and slope have good influence on occupancy of Sumatran serow. The factors ofspatial habitat have positive correlation to PAO. Sumatran serow occupancy was greaterin grid cells that were further from the forest edge, in grid cells that were located onsteeper slopes, and also from others spatial habitat factors.Key words: The factor of spatial habitat; sumatran serow; PAO; detection probability; Sipurak.

Abstract

An indirect enzyme-linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectiousbronchitis (IBV). Antigen was prepared from whole virus of infectious bronchitis local isolate PTS-III serotype.Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera indeveloped ELISA were determined 0.4μg/well, 1:2000 and 1:100, respectively. Correlation optical densities (OD)were compared with a standard commercial ELISA (R2=0.933). The developed ELISA has a better sensitivity to hemagglutinationinhibition (HI) test. The developed local isolate ELISA can be used to detect antibody against infectiousbronchitis virus and it is suitable for sample screening at the diagnostic laboratories.Keywords: ELISA, antibody, chicken, IB PTS-III local isolate

Abstract

Mass propagation of leafy Anthurium (Anthurium spp.) from seed by in vitro technology. We have developed an efficient in vitro propagation of A. plowmanii from seed explants. The protocols include inoculation of seed in MS medium supplemented with 2 g/l BA. This medium is used to proliferate cluster of buds that developed from seeds. To induce the growth of the shoots from the bud clusters, the clusters were devided and transffered to MS medium enriched with 340 mg/l KH2PO4 and 0,1 mg/l BA and 0,05 mg/l NAA. To get high survival rate, the clusterof shoots were acclimatized as a whole cluster that in turn the shoots become easily separatable from each other during the growth. The acclimatized plantlets grew into mature plants through serial transfer to bigger pots and regular fertilizer application. This technology is applicable to other leafy anthuriums as well.Key words: leafy Anthurium, in vitro technology, BA, NAA, KH2PO4, plowmanii, hookeri, jenmanii, longilinguum
