Abstract

ABSTRACTPollinator Bat Identification Based on Pollen as Feed Resources at LinggarjatiDistrict-Ciremai National Park, West Jawa. Pollen identification that used for feedresources by six species of frugivorous bats from Ciremai National Park was identifiedunder microscope. The results shown that are known 21 species as important plants forbats and in the contrast possibly for bats as pollinator. By the principle componentanalysis and cluster grouping based on Euclidian distance indicated that Aethalops alecto,Chironax melanocephalus as important polinator role in primary forest and high in elevationlevel, C. brachyotis and Macroglossus sobrinus in secondary or fragmented forest andMegaerops kusnotoi in lower primary forest and Cynopterus tittacheilus is important rolefor intermediate area between primary and secondary forest and at lower elevation range.On the niche overlaps analysis indicated that the highest overlaps were known in C.brachyotis and M. sobrinus (0.881) but the lowest in niche overlaps between M. sobrinusand C. melanocephalus (0.288)Key words: pollen, bats, feed resources

Abstract

Vocalizations Rhacophorus edentulus Mueller, 1894 have never been described before. The advertisement calls of four individual males of R. edentulus which originated from Mekongga Mountains, Southeast Sulawesi were recorded in December 7-8, 2010 at air temperatures of 20.5°C.  Location of sound recording for the four individual males were performed at two different places, call of one individual was recorded when it was calling in a plastic bag in the base camp, while calls of the other three individuals were recorded in their habitat in the forest. Adobe Audition 3.0 software was used to visualize sound waves.  Calls of R. edentulus have two types, i.e. pulses and pure tone.  Sound wave of pulses has two types, namely pulse type 1 and pulse type 2; whereas sound wave of pure tone also has two types, namely pure tone type 1 and pure tone type 2.  Based on the dominant frequency and the fundamental frequency of pure tones waves and pulse waves, the natural noise in the forest habitats affects the dynamics of the frequency of calls that were released by males R. edentulus; frequency sound with low noise is more dynamic than the frequency of the sound with high noise level. Key words: vocalization, Rhacophorus edentulus, Mekongga Mountains, Southeast Sulawesi.

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

ABSTRACTThis study aims to determine the cross-reaction between the antigen of avian influenza (AI) H5N1 virus clades 2.1.3 and 2.3.2 in duck and chicken sera, which were vaccinated with inactivated AI H5N1 clade 2.1.3 vaccine against AI H5N1 clade 2.3.2 antigen and those vaccinated with inactivated AI H5N1 clade 2.3.2 vaccine against H5N1 clade 2.1.3 antigen. The sera tested were obtained from postvaccination and control (unvaccinated) chickens and ducks in the laboratory condition, and from AI H5N1 postvaccination ducks in the field condition. HI test was conducted by using AI H5N1 clades 2.1.3 and 2.3.2 antigens. The results of HI titer were analyzed by the geometric means and by ANOVA. The results show that cross-reactions in both chicken and duck sera after AI H5N1 clade 2.3.2 vaccination tested with AI H5N1 clade 2.1.3 antigen occurred with low antibody titers, whereas in chicken and duck sera postvaccination with avian influenza H5N1 virus clade 2.1.3 showed cross-reaction with high antibody titer against clade 2.3.2 antigen. The conclusion of this study, postvaccination sera of AI H5N1 clade 2.1.3 provide better cross-reaction compared to the postvaccination sera of AI H5N1 clade 2.3.2.Keywords: sera, chicken, duck, AI H5N1, clade 2.1.3 and clade 2.3.2.

Abstract

ABSTRACTBacterial inoculants affect the early growth of Jatropha (Jatropha curcas L). Genera ofAzotobacter, Bacillus, Chromobacterium, Citrobacter, Nitrosomonas, Rhizobium, andSpaerotillus natans were soil bacterial isolates. The soil was collected from numerous placesaround Pontianak, West Kalimantan. Those isolates were used as inoculants, and formulatedto single and mixed bacterial inoculants, then used to stimulate the early growth of jatrophaseedling in 15 weeks at greenhouse condition. Bacterial inoculations caused better growthperformance compared to its control as pure soil garden medium without inoculations, andneither to bare soil dresses with compost. In the presence of inoculants, plant height wasaccelerated quickly while other inoculants affected to stalk diameter development. Daily growthperformance of jatropha peaked in 8 and 11 weeks after inoculation of Citrobacter andNitrosomonas bacterial component were used as single inoculant, respectively. The increasingof shoot biomass accumulation was three times as caused by single inoculants (Bacillus sp),and the highest one up to four times of biomass weight caused by a mixture inoculants asconsortium of Azotobacter, Bacillus, and Nitrosomonas spp. That selective inoculant hasopportunity to be used for jatropha farming, and this basic study is meaningful to jatropacultivation for standing to bio-fuel resources.Keywords: Jatropha curcas L., inoculants, Azotobacter, Bacillus, Chromobacterium,Citrobacter, Nitrosomonas, Rhizobium , Spaerotillus natans.Kata kunci: Jatropha curcas L., inoculants, Azotobacter, Bacillus, Chromobacterium,Citrobacter, Nitrosomonas, Rhizobium , Spaerotillus natans.

Abstract

Percentage changes of litter nutrient due to decomposition process of four deciduous plant species in Purwodadi Botanic Garden. The nutrient release pattern of plant litter is different among species. Decomposition and nutrition release of organic material was observed in four species Swietenia macrophylla, Lagerstroemia speciosa, Ficus benjamina and Kigelia Africana in Purwodadi Botanic Garden. Litter mass was measured and chemical compositionwas analized including poliphenol, celulose, lignin, carbon (C), Nitrogen (N), C/N ratio, phospor (P), and Kalium (K) during 3 months. Litterbag method was applied in this research. Freshlitters were brought into bag and placed in the forest floor. Litterbag and litter chemical monitoring was established once a week. The research result showed that C ratio of four species in early phase increase then decrease in late phase of incubation and significantlydifferent from initial phase except in F. benjamina. N ratio decreased in first month and increases until late phase of incubation. C/N ratio increase in early phase then significantly decreasesuntil 3 months incubation. P ratio tends to decrease in first and third month. Ratio of polyphenol and Lignin decreases, however celluloses increase. The litter of four species has low chemical quality, respectively have low C/N ratio (< 25 %), lignin < 15 %, poliphenol < 3 % and (L+Pp)/ N > 8 %. Consequently, the litter tends to immobilize than mineralize. It effected to high ratio ofN such in L. speciosa. Decreasing and releasing of N in K. Africana showed that its nutrient transfer is better than in other species. P ratio quickly decreases in first 4 weeks of decomposition, it showed that P is not a limiting factors in species decomposition, relatively.Keywords : Litter, decomposition, percentage changes, nutrient
