Abstract

ABSTRACTPotential virus A/Ck/West Java/PWT-Wij/06 for Vaccin. Vaccination program for controllingavian influenza (AI) virus infection in poultry have been emerged during the past 5 years inIndonesia. However, due to the mutation character of this virus the available vaccines were nolonger effective. Therefore a new local isolate of avian influenza virus A/Ck/West Java/Pwt-Wij/2006 was studied. The virus, formulated as inactive vaccine, was injected in to 3 weeks oldof layer chickens intramuscularly. At 3 weeks after vaccination, vaccinated chickens werechallenged against seven local isolates of HPAI H5N1 intranasaly. Unvaccinated chickenswere included in the challenge test as control. Results showed that the vaccine produced100% protection against A/Ck/West Java/Pwt-Wij/2006 (homologous), A/Ck/West Java/1067/2003, A/Ck/West Java/Hj-18/2007, and A/Ck/Payakumbuh/BPPVRII/2007; produced 90%protection against A/Ck/BB149/5/2007, and 80% protection against A/Ck/West Java/Hamd/2006 isolates. The vaccine also stoppped viral shedding by day 5 to 7 after challange. Thisstudy indicate that the new local isolate of avian influenza A/Ck/West Java/Pwt-Wij/2006 hasgood potency as vaccine with broad spectrum against a range of AI viruses available inIndonesia.Key words: avian influenza, HPAI, H5N1,vaccine, poultry.

Abstract

Deforestasi di Taman Nasional Bukit Barisan Selatan, Sumatra, Indonesia. Studi ini menerangkan deforestasi dan penyebabnya di Taman Nasional Bukit Barisan Selatan (TNBBS) yang merupakan habitat bagi berbagai satwa liar yang terancam punah. Penelitian ini menghubungkan metode penginderaan jauh dengan metode wawancara untuk memperkirakan laju deforestasi dan mengetahui penyebab deforestasi. Hasil wawancara menunjukan bahwa penggundulan hutan di TNBBS di mulai sejak tahun 1960an, lebih awal dari perkiraan sebelumnya.Hasil tersebut di perkuat oleh hasil analisa citra-satelit yang menunjukan bahwa sebelum 1972 tutupan hutan seluas 46.100 ha atau sekitar 13% dari luas hutan di TNBBS telah hilang. Ratarata laju deforestasi sejak 1972 hingga 2006 adalah 0,64% per tahun. Hanya sekitar 67.225 hahutan yang tersisa pada 2006 dari 310.670 ha hutan pada tahun 1972, atau sekitar 22% tutupan hutan telah hilang sejak 1972 hingga 2006. Laju deforestasi di TNBBS paling tinggi di hutan perbukitan (9.01 km2/tahun), kemudian hutan dataran rendah (7.55 km2/tahun), and hutanpegunungan (3.43 km2/tahun). Deforestasi tertinggi terjadi pada dekade pertama (1972-1985), setiap tahunnya seluas 28 km2 hutan di babat habis, kemudian pada dekade berikutnya (1986-1996) deforestasi hanya 15 km2/tahun, namun pada dekade terakhir deforestasi meningkat kembali(21 km2/tahun). Pelaku yang secara fisik membabat hutan di TNBBS adalah petani yang tinggal di dalam dan di sekitar hutan. Meskipun demikian, yang menjadi penyebab terpenting deforestasidi TNBBS adalah penyebab tidak langsung seperti illegal logging, Hak Pengusahaan Hutan, tingginya harga kopi, lemahnya penegakan hukum, dan situasi sosial-ekonomi di tingkat lokal dan nasional. Faktor-faktor tersebut merupakan faktor external yang mendorong petani untukmembuka hutan di TNBBS atau memperluas lahan garapannya.Kata kunci: Deforestasi, Penyebab deforestasi, Survei wawancara, Penginderaan jauh, Taman Nasional Bukit Barisan

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

ABSTRACTVariation in The Mitochondrial Cytochrome b Gene in The Two White Cockatoo Species (Cacatua alba and C. molucensis). DNA sequence variation in the 791-bp of mitochondrial cytocrome b gene in the two white cockatoo species (C. alba and C. moluccensis) were analyzed in this study. Two pairs of internal primers used to amplify two fragments of cytochrome b from 30 individuals cockatoo. The results show that there were genetic variations among individuals of C. alba and C. moluccensis. Twenthy eight haplotypes occured in 30 individuals studied; 14 haplotypes (Hca1-Hca14) in 16 individuals of C. alba, and 14 haplotypes (Hcm1-Hcm14)in 14 individuals of C. moluccensis. Hca5 was dominant and owned by 3individuals (H37, KBS62, 28, BBP88). Within C. alba there were 18 variable sites, 0.00701 of nucleotide diversity (Pi), 0.975 ± 0.035 of haplotype diversity (Hd), and 0.005 ± 0.002 of mean genetic distance. Whitin C. moluccensis there were 18 variable sites, 0.00830 of Pi, and 0.9999± 0.028 of Hd, and 0,010 ± 0.002 (0.001-0.010) mean genetic distance. Divergence between C. alba and C. moluccensis was 0.064 ± 0.088 %. Neigbor-joining (NJ) analysis showed two main clusters consisted of : C. alba and C. moluccensis separately, and indicated that althoughthere were some variations in the DNA sequences, but the individuals within a species remain clustered in the same cluster.Key words: genetic variation, mitochndrial cytochrome b, cockatoo bird, Cacatua alba, Cacatuamoluccensis

Abstract

ABSTRACTGenetic variation and relatedness of two new species of star fruit (Averrhoa leucopetalaRugayah et Sunarti sp nov and A. dolichorpa Rugayah et Sunarti sp nov., Oxalidaceae)based on Random Amplified Polymorphic DNA. Two wild species of Averrhoa from Papuaand Gorontalo respectively has recently been described. These two species were previouslytreated as ‘intermediate species’ between A. carambola and A. blimbi on the basis ofmorphological characters. This present study aimed to assess genetic variation and geneticrelatedness of the two species compared to their relatives (A. carambola and A. blimbi) byusing Random Amplified Polymorphic DNA (RAPD). Five RAPD primers (OPA 9E, OPA 13,OPB 7, OPB 18 dan OPN 12) were used to amplify total DNA genom and produced 31 bands towhich 90.32% were polymorphic. These bands were ranging in size from 300-1700 bp. DNAfingeprints for each species was indicated by differences in RAPD profiles resulted fromamplification of five primers. Clustering analysis was performed based on RAPD profilesusing the UPGMA method. The genetic similarity range between 0.25-1.00 indicating widerange of genetic variations observed. Results also indicated that the two species weregenetically distant from A. carambola and A. blimbi, thus supported the recent morphologicaltreatment.Key words: Averrhoa, RAPD profiles, genetic variations.

Abstract

ABSTRACTPreliminary study: Gene transfer from transgenic potato Katahdin RB to non transgenicpotato. One of the concerns associated with the release of transgenic crops, is the possibilityof the gene flow from transgenic crops to neighboring crops of the same species or to relatedspecies. In plants, gene flow is a routine process occur through the natural hybridization. Theopportunity for gene flow occur depends principally on two factors, the degree of sexualcompatibility between donor and recipient species, and the physical distance between thetwo. The experiment was conducted to determine whether the gene flow from transgenicpotato Katahdin RB to non transgenic was occurred, based on selection using a 50 mg/lkanamycin, and to estimate gene flow mediated by natural hybridization at different isolationdistances. Preliminary result indicated that a rapid and simple method using MS0 liquid mediawith kanamycin 50 mg/l was effective for screening the seeds. There was a gene flow fromtransgenic potato Katahdin RB to non transgenic, based on a rapid and simple selectionmethod using 50 mg/l of kanamycin as selectable marker. The isolation distance used in thestudy were 0.8, 1.6, 2.4, 3.2, 4.0, 4.8, 5.6, 6.4, 7.2, 8.0, 8.8, 9.6, 10.4, and 11.2 m from the row oftransgenic potato Katahdin RB. The gene flow through natural hybridization at a isolationdistances of (0.8 - 1.6 m), (2.4 – 4 m), and (4.8 – 6.4 m) from transgenic to non transgenic plantswere 13.78, 10.92, and 3.82%, respectively. At a distance of 7.2 – 8 m, the frequency of gene flowwas declined to 0%. The frequency of gene flow from transgenic potatoes to non transgenicpotatoes markedly decreased by increasing the isolation distance, and was negligible at 7.2 m.Key words : natural hybridization, transgenic potato RB, kanamycin selection

Abstract

ABSTRACTThe Effect of Environmental Factors on the Horizontal and Vertical Movement of Frogs. Fourenvironmental factors (moon phase, air temperature, water temperature and air humidity) weremeasured to determine the impact of environmental factors on the dynamics of horizontal andvertical spread of the frog Rana erythraea, R. nicobariensis and Occidozyga lima in a wetlandarea of Ecology Park, LIPI Campus Cibinong. Observation was done follows transect line(100 meters long) and set along the edge of the lake where the habitat was more diversecompared to the other sites. Observations were carried out from July to November 2009. Theposition of individual frogs (distance from water’s edge and height from the ground or water)was recorded and then grouped into intervals of 100 cm distance and height each. Correlationanalysis between the number of individuals per unit distance or height with environmentalfactors was measured using the statistical program SPSS version 16.0. The results of thisstudy proved that the air and water temperature as well as air humidity have significant effecton horizontal and vertical ecological distribution of R. erythraea and R. nicobariensis; whereasfour environmental factors had no impact on horizontal distribution of O. lima. The movementof R. erythraea was strongly positively correlated with air temperature, but strongly negativelycorrelated with air humidity; however the abundance of R. nicobariensis was strongly negativelycorrelated with air temperature and strongly positively correlated with air humidity. Mixedvegetation of species Leerxia hexandra and Eleocharis dulcis at a distance between 0-100 cmfrom the edge of the water and height between 0-100 cm from the ground constituted thepreferred microhabitat of frog species R. erythraea and R. nicobariensis.Key words: Environmental factors, Rana erythraea, Rana nicobariensis, Occidoziga lima,Ecology Park, wetland.
