Abstract

ABSTRACTThe Mega Bat (Pteropodidae) Distribution on Several Land Coverage at Surrounding KerinciNational Park. The study of bats was carried out on May 2005 to July 2005. In all 5 major landuse system (primary forest, disturbed forest, old rubber plantation, young rubber plantationand mix garden) survey was conducted using the same standardized mistnetting. Each of theland use system was sampled for 4 days using 4 mist-nets a night. The total of 2512.5 m2 ofmist-nets night area were set during this survey. A total of 156 bat individuals which consist of14 specieses and 5 families (Pteropodidae, Vespertilonidae, Emballonuridae, Hipposideridaeand Rhinolophidae) acquired. Calculation result using the diversity index measurement frombat samples indicate that the highest diversity was in disturbed forest habitat (H’=1.831;E=0,865) and the lowest was in forest habitat (H’=0.5; E=0.561), meanwhile the biggestdominancy reside in the young rubber plantation (?=0.767) and disturbed forest had the lowestdominancy (?=0,138). The most dominant at young rubber plantation habitat is Cynopterusbrachyotis. The result of clustering analysis using SPSS 11.5 showed that habitat type weredivided become 2 clusters which were old rubber and non old forest (forest, disturbed forest,young rubber plantation and mix garden). This division showed that forest and non forest hada distinctively different habitat. According to Canonical Correspondence Analysis (CCA) byusing Canoco for Windows version 4.5 indicated that physical parameter such as temperature,humidity, rainfall and altitude influenced the distribution, commnunity and clustering of batsfor land use systemKey words: Bats, diversity, Kerinci Seblat National Park, land use type, rubber plantation

Abstract

ABSTRAKPengelolaan Taman Nasional dalam Era Otonomi Daerah Dilihat dari Perspektif PolitikKonservasi Biology: Studi Kasus Tanjung Puting -Kalimantan Tengah. Paper ini menganalisispengelolaan taman nasional dilihat dari perspektif politik ekologi yang menekankan atas perandan persepsi ‘stakeholders’. Peran taman nasional adalah sangat penting sebagaibenteng terakhir dalam menjaga keberadaan hutan alam. Tetapi, kondisi riil Taman NasionalTanjung Puting sekarang ini menghadapi suatu ancaman, karena dua faktor penting yakniadanya praktek aktivitas illegal logging dan penggalian untuk usaha tambang, yang dilakukanoleh para pedagang kayu dan investor lokal dari luar dengan menyuruh masyarakat lokal untukmemotong pohon dan menggali tanah. Dengan demikian, untuk mengantisipasi masalah yangkritis tersebut, diperlukan aksi afirmatif seperti pengelolaan kolaborasi dengan berbagaistakeholders (pemerintah daerah baik propinsi dan kabupaten, LSM, masyarakat lokal) atasprogram reboisasi berbagai pohon, penegakkan hukum, sanksi yang keras, dan pemberdayaanekonomi dan sosial bagi masyarakat lokal. Terjadi juga konflik kepentingan antara pemerintahpusat dan daerah dalam pengelolaan sumber daya hutan, khususnya taman nasional.Pemerintah pusat berpendapat, berdasarkan UU No.5/1990, pasal 14, yang menekankan ‘tamannasional sebagai sarana preservasi hutan alam yang memilki kehidupan ekosistem yang unikdan dikelola berdasarkan sistem zonasi (inti, rimba dan riset). Kewenangan pengelolaan tamannasional tersebut diberikan kepada pemerintah pusat, karena misi utamanya ialah ialah untukmenjaga keanekaragaman hayati, memproteksi dan mengembangkannya. Sebaliknya pemerintahdaerah (Propinsi dan Kabupaten) berpendapat, bahwa keberadaan taman nasional di daerahnya,dapat digunakan sebagai income PAD (Pendapatan Asli Daerah), untuk membanguninfrastruktur daerah dan meningkatkan kesejahteraan masyarakat, khususnya dalam masa Otda.Sejalan dengan misi pemerintah daerah, masyarakat lokal juga melihat ‘taman nasional’ darikeuntungan nilai ekonomi langsung, sehingga sering terjadi praktek aktivitas illegal lggingdan tambang di kawasan taman nasional Tanjung Puting yang pada akhirnya berakibat terhadaprusaknya hutan. Dalam konteks ini, baik kepentingan konflik antara dua aktor stakeholdersyang utama baik pemerintah pusat dan daerah sangat menarik untuk dikaji.Kata kunci: Pengelolaan taman nasional, kolaborasi, stakeholders, kepentingan konflikpemerintah pusat dan daerah.

Abstract

ABSTRACTParturition Behavior and Estrus of Sulawesi spiny rat Maxomys hellwandii (Jentink, 1879).This research is aimed to study the parturition behavior of wild Sulawesi spiny rat involvingobservations of pre-parturition, parturition and post- parturition behaviors. In this study, 15female white tail rats at the ages of 60 days old were used to evaluate their estrus. Animals weremaintained in cages made of glass at size of 1m x1mx1.5m. The covers of cages were made ofram wire and completed with feeder and drinker. For estrus observation, animal cages weremade of plastic trays of 39 cm x42 cm x15 cm. The phase of estrus cycles observation was doneby collecting sample of vagina smear from the animals. The determination of cycles phase wasbased on the cell types that were obtained from preparation vagina smear. The results showedthat about six hours before parturition, the animals were nervous and urinated 4 to 9 times asthey showed agonistic. The parturition process needed 3 to 8 minutes. The deviation times ofsuckling progeny were 8-12 seconds. The progeny at the ages of 1 to 5 days old slept againsttheir mother nipples. For the estrus, the results showed that estrus cycle of wild white tail ratswas ranging from 3 days to 5 days, consisted of pro estrus (12 hours), estrus (12 hours), metestrus (18 – 12 hours) and di-estrus (45 - 54 hours).Key Words: Parturition Behavior, Estrus, Maxomys hellwandii.

Abstract

ABSTRACTGenetic Mapping of Indonesian Avian Influenza Viruses 2007.Department of agricultureimplements vaccination as one a tool to control of avian influenza disease. The vaccinationprogram use virus seed such as H5N1, H5N2 and H5N9. Such as vaccination program for otherdiseases, avian influenza vaccine program have lack implementation in the field. In 2007,department of agriculture evaluated the AI vaccination program such as the master seedvaccine that can be used. Result of the evaluation showed that 11 of AI vaccines that weredistributed in Indonesia did not give protection more than 60% to Indonesian isolates in 2006(A/Ck/Pwt-Wij/06). From this point and many AI cases in the field in 2007, the aim of thisstudy was to conduct genetic diversity of avian influenza viruses which have circulated inIndonesia region. We used virus isolation for propagate the viruses, RT-PCR for identificationand DNA sequencing on HA1 region to analysis genetic diversity for genetic mapping anduseful for master seed candidate. The result of the study showed that there were 6 group ofgenetic diversity in 2007; Isolates from group 1, 5 and 6 can be used for AI vaccine candidate.Key words: genetic mapping, genetic diversity and avian influenza viruses

Abstract

ABSTRACTCharacterization of Nitrile Hydratase and Amidase of Pseudomonas sp BP3 in Bioconversionof Adiponitrile to Adipic Acid. Adipic acid is a commercially important compound, primarilyused as precursor for the production of nylon 6.6. It is also used for plasticizer, fibers, and foodadditive. Synthesis of adipic acid by chemical means requires large amount of energy andconcentrated acid. It also produces N2O as by product, which is very toxic and suspectedcauses depletion of the ozone layer. The purpose of this research was to study thebioconversion of adiponitrile by Pseudomonas sp. BP3 and to characterize the involved enzymesin the whole cell. Pseudomonas sp. BP3 was able to utilize adiponitrile as the sole source ofcarbon and nitrogen. It’s doubling time (td) and growth rate constant (?) during the growth inadiponitrile were 2 hours and 0.346/h, respectively. The optimum pH and temperature of nitrilehydratasewere pH 7.0 and 30°C, respectively, while those of amidase were pH 6 and 50°C.Vmax and Ks of nitrile hydratase were 8.3 nM/ml.min. and 55.56 mM, respectively, and ofamidase were 5,9 nM/ml.min and 50 mM. The rate of adiponitrile consumption was 0.245 mM/h and of adipic acid formation was 0.181 mM/h. The yield of bioconversion of adiponitrile andadipamide were about 50 % and 25%, respectively.Key words: Bioconversion, adiponitrile, adipic acid, Pseudomonas sp. BP3, nitrile hydratase,amidase

Abstract

ABSTRACTVegetation structure and carbon stock of primary tropical rain forest at Batang Toru, NorthSumatra. Deforestation and forest degradation contribute for 20 to 25 percent of annual totalcarbon dioxide (CO2) emissions and to be one of substantial factor of climate change or globalwarming. Avoided deforestation into carbon-market regime by reducing emission fromdeforestation and forest degradation (REDD) scheme has been agreed on COP 13 of UNFCCCthat was held in Bali on December 2007. REDD application need reliable scientific basic aboutthe amount of carbon storage in well managed natural forest. The aims of this research were todetect vegetation structure and to estimate aboveground biomass, carbon stock and CO2absorption of primary tropical rain forest at Key Biodiversity Area of Batang Toru ForestBlock, North Sumatra Province by existing allometric equation. We designed 20 sampling plotsof 20 x 20 m in two forest area, i.e. Aek Game-game forest and Aek Silemes forest. All trees 5 cmat diameter at breast height (dbh) and above were measure and identified. From the study, thedistribution of diameter class formed “L” curve which mean an indication as balanced forest.The aboveground biomass of the forest is 544.4 to 583.0 t/ha in Aek Silemes forest and 604.5 to613.6 t/ha Aek game-game forest. It is equivalent with 272.2 to 291.5 t C/ha or 999.0 to 1,069.9 tCO2/ha in Aek Silemes forest and 302.2 to 306.8 t C/ha or 1,109.2 to 1,125.9 t CO2/ha in Aekgame-game forest. More of carbon stock (>46% for Aek Silemes forest and >58% for Aek gamegameforest) saved within dbh of trees 50 cm and above. Therefore, sustainable managementof forest ecosystem is very important to reduce CO2 emission from deforestation and forestdegradation and to improve the function of forest ecology and economy.Keywords: aboveground biomass, carbon stock, CO2, primary tropical rain forest, BatangToru-North Sumatra
