Judul: Tabel Berat Pohon Tegakan Akasia Mangium (Acacia mangium Willd) (Studi Kasus di IUPHHK-HA PT. Bumi Pratama Usaha Jaya Sumatera Selatan)
Abstrak: The availability of tools in a Comprehensive Forest Inventory Periodic activities (IHMB) are necessary to speed up the activities and minimize the errors that occur in the measurement. The purpose of this research is composing the tree weight table of Acacia mangium (Acacia mangium Willd) species in IUPHHKHA PT. Bumi Pratama Usaha Jaya. Results of the regression analysis were taken into three categories that can indicate good or bad for an equation is the coefficient of determination ( ), standard error (SE) and count. The model validation can be performed using the aggregation deviation test (SA), the average deviation (SR), the RMSE (Root Mean Square Error), the value of the bias and real difference test conducted with the chi-square test between the alleged weight with the weight of fact table. Based on the results obtained, the equation can be used to infer a tree weight with skin and without skin based on the diameter in IUPHHK-HA Acacia mangium plant area of PT. Bumi Pratama Usaha Jaya each have Bdk = 0,4799 D1,9109 equation for tree weight with skin and Btk = 0,2096 D2,0841 equation for tree weight without skin.

Judul: Model persamaan alometrik biomassa dan massa karbon pohon Akasia mangium (Acacia mangium Willd.): studi kasus pada HTI Akasia mangium di BKPH Parung Panjang, KPH Bogor, Perum Perhutani Unit III Jawa Barat dan Banten
Abstrak: Increasing concentrations of greenhouse gases like carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulfur hexafluoride (SF6) in the atmosphere already have environmental impacts caused by rising air temperature at the earth. Forests can absorb greenhouse gases by way of transforming CO2 from the air to deposit the carbon stored in trees. Acacia mangium is a fast growing tree species having ability to tolerate wide-range soil conditions, which make this spesies attractive for tree planting in critical lands. This research was conducted in Acacia mangium plantation forest at Parung Panjang Sub-District, Bogor District, Perum Perhutani Unit III, West Java and Banten. The objective of this research are (1) to learning the carbon content of tree biomass component, (2) to learning the allometric equation models for biomass and carbon mass estimation and (3) estimating the carbon stocks of Acacia mangium plantation. Selection of sample trees in each diameter class were conducted by purposive sampling, starting from diameter class 0-5 cm to those of 35-40 cm. Laboratory tests were conducted to determine the carbon content of tree biomass component. Selection of the best equation was conducted by using allometric regression based on the highest R2(adj). The results of the case study on Acacia mangium stands, showed that there is a differences in carbon content of tree biomass component (roots, stems, branches, twigs and leaves). The highest carbon mass is in the main stem of the tree, and the lowest is in the leaves. The model of tree biomass allometric equation of Acacia mangium is W = 0,140928 D2,31 and tree carbon mass allometric equation is C = 0,060255 D2,39. Potency of carbon stocks in Acacia mangium plantation forest at Parung Panjang Sub-District was 25,4183 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.
