Judul: Model Penduga Biomassa Pohon Agathis (Agathis loranthifolia) Berdiameter Kecil di Hutan Pendidikan Gunung Walat, Sukabumi, Jawa Barat
Abstrak: One of the tree species for rehabilitation in Gunung Walat University Forest (GWUF) is agathis (Agathis loranthifolia). The biomass of small diameter agathis (≤ 10 cm) can be estimated by using Biomass Expansion Factor (BEF) and allometric biomass model, either for each tree component (stem, branches and twigs, and leaves) or for the total of above ground biomass. Based on data analysis using 32 sample trees, the stem biomass was 74%, branch biomass was 16%, and leaf biomass was 10%. The BEF of small diameter agathis was 1.075 (for lower wood density (WD)), 1.022 (for medium WD), and 0.944 (for higher WD). The allometric biomass models for each tree component and total biomass are Wstem = 0,0139dp3,132 (R2 = 99,2%), Wbranches and twigs = 0,0042dp2,963 (R2 = 97,3%), Wleaves = 0,0115dp2,276 (R2 = 97,1%), and Wtotal = 0,0276dp2,945 (R2 = 99,0%), where dp is collar diameter

Judul: Model Alometrik Biomassa Puspa (Schima wallichii Korth.) Berdiameter Kecil di Hutan Pendidikan Gunung Walat, Sukabumi
Abstrak: One of tree species in Gunung Walat University Forest (GWUF) is schima (Schima wallichii Korth.). Schima can produce timber and absorb carbon dioxide emission from the atmosfer. The objective of this study was to determine biomass expansion factor (BEF) and biomass conversion and expansion factor (BCEF) and to develop allometric biomass model for small diameter of schima. This study used destructive sampling method to measure biomass of 30 sample trees. The biomass content of stem, branch, and leaves of schima was 76.13%, 14.34%, and 9.53% respectively. The average BEF value of schima was 1.36, while the average BCEF value was 626.03 kg/m3. Allometric biomass models for stem, branch, leaves, and total aboveground biomass of schima were Wstem = 0.128DBH2.244, Wbranch= 0.021DBH2.342, Wleaves = 0.032DBH1.928, and Wtotal = 0.178DBH2.222 respectively.

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.
