Judul: Analisis cadangan karbon pada perkebunan sawit menggunakan citra satelit landsat: studi kasus Perkebunan sawit di Kec. Hanau dan Danau Sembuluh, Kalimantan Tengah
Abstrak: Analysis of carbon stock in two different vegetations is based on the coversion of non oil palm plantation land cover (this study consisted of agriculture and plantation forests, rubber, bush) into oil palm plantation and a large emmiter of carbon in Indonesian, especially in Sumatra and Kalimantan. The method used to estimate carbon stocks is approaching the energy balance method with Landsat satellite image processing, where energy which is received by the canopy for photosynthesis process will produce potential biomass through Beer-Lambert law. The potential of biomass is converted into carbon stock value with multiplying the potential biomass value by 0.4. Non oil palm and oil palm plantation have a small difference of carbon stock value. Carbon stock distribution map shows that in 2001 the carbon stock of oil palm plantation is 25.59 to 41.06 ton/ha, while the other ranging from 25.56 to 41.03 ton/ha. In 2004 carbon stocks in oil palm plantation ranging from 14.18 to 38.45 ton/ha, while the other ranging from 14.01 to 38.39 ton/ha. In 2008 carbon stocks in vegetation of oil palm plantations ranging from 25.61 to 41.71 ton/ha, while the other ranging from 25.61 to 41.26 ton/ha. In 2009 carbon stock in oil palm plantations ranging from 23.98 to 38.60 ton/ha, while the other ranging from 23.97 to 38.54 ton/ha.

Judul: Pendugaan Cadangan Karbon Biomassa Di Lahan Gambut Kebun Meranti Paham, PT Perkebunan Nusantara IV, Labuhan Batu, Sumatera Utara
Abstrak: Carbon stock of peatland in the oil palm is an important role in balancing global climate to support sustainable management of oil palm plantation. The study was carried out in oil palm of Meranti Paham, PT. Perkebunan Nusantara IV, Labuhan Batu, North Sumatra. Carbon stocks of terrestrial ecosystems consist of carbon above ground including carbon stocks of oil palm and shrubs, and below ground carbon. The aim of study was to estimate the amount of carbon stored above and below ground in oil palm of peatlands estates of Meranti Paham, PT. Perkebunan Nusantara IV, Labuhan Batu, North Sumatra. Data was collected by field measurement and laboratory analysis. Peat carbon stock calculation was based on weight of peat per unit area that was calculated by using multiplication of the study area x bulk density x organic carbon content x peat depth, whereas carbon biomass of oil palm calculation was based on destructive method. The result showed that carbon stocks in the oil palm biomass and shrubs of Meranti Paham Estates, about 122.108 tons and 2.595 tons. The total carbon biomass stocks above ground contained in Meranti Paham, PT. Perkebunan Nusantara IV, approximately 124.703 tons. To measure the carbon stored in peat soil based on degree of decomposition of peat. The data required were the bulk density (BD), carbon content, thickness and area of peatlands. These data are directly proportional to the carbon content is stored. Carbon stock of below ground contained in hemik an average about 1.270.272 tons and fibrik an average about 9.078.600 tons. Thus the average total carbon stock below ground of Meranti Paham Estates is about 10.348.872 tons. Finally, total carbon stocks of Meranti Paham Estates in 2009 obtained by summing up carbon stocks of above and below ground, that obtaines result about 10.473.575 tons.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
