Judul: Model Persamaan Alometrik Penduga Biomasa Hutan Alam Tropika di Areal IUPHHK-HA PT. Wapoga Mutiara Timber, Papua
Abstrak: This research aims to create allometric equation models to estimate the biomass of tropical natural forests in eastern Indonesia. Allometric equation models made by destructive methods and using purposive sampling method to take 30 sampling trees. Best equation model to estimate tree biomass of this research consists of biomass tree parts model and total tree biomass model. Models to estimate the biomass of the tree parts such as W = 0.0245 D2,23 Tt0,74 to estimate the stem biomass, W = 0,0003 D3,91 Tbc-0,66 for the branch biomass, W = 0,054783 D2,42 Tt-0,63 for twigs biomass, and W = 0,0513 D1,62 for leaf biomass. The best model to estimate the total biomass is W = 0,0655 D2,52Tbc0,23 where W is biomass, D is diameter at breast height (cm), Tbc (clear bole), and Tt is the total height of the tree. This models have R2(adj) of 78,31 – 97,75% and the deviation (s) of 0,1337 – 0,3201.

Judul: Model Persamaan Alometrik Penduga Biomassa dan Masa Karbon Pohon Di Hutan Alam Tropika Basah (Studi Kasus Di ArealIUPHHK-HA PT Suka Jaya Makmur, Kalimantan Barat)
Abstrak: Global warming is one of green house effect phenomena which cause by increasing the concentrations of greenhouse gases (GHG) emissions in the atmosphere, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), and sulfur hexafluoride (SF6). Forests can absorb CO2 from the air and store in the trees. Tropical natural moist forest is one of the forest types, which can absorb CO2 very well so it has quite high potential carbon stock. This studies was conducted in IUPHHK-HA PT Suka Jaya Makmur, West Kalimantan. The main goal of this study is to get tree biomass and carbon allometric equations of tropical natural moist forest in IUPHHK- HA PT Suka Jaya Makmur. Sampling conducted by purposive sampling. Laboratory analysis of sample materials were done in the Laboratory of wood chemistry, Department of Forest Product, Faculty of Forestry to determine the carbon content in each part of the tree. The best equations was selected based on the highest R2(adj) and the smallest standard deviation (s) value. Estimation of biomass and carbon mass were done on roots, stems, branches, twigs, and leaves of the tree. The results of this study indicate that the carbon content of every part of the trees (roots, main stems, branches, twigs and leaves) are very significant difference. Allometric equations for tree biomass was selected Btot=0.2729D2.53Tbc-0.332, and model allometric equations to estimate potential carbon Ctot=0.1503D2.57Tbc-0.357. The potential of biomass and carbon mass location of each study is 68.35 ton/ha and 41.69 ton/ha.

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.
