Judul: Pendugaan Potensi Tegakan Shorea sp Menggunakan Metode Tree Sampling dan Circular Plot di KHDTK Haurbentes, Kabupaten Bogor
Abstrak: This study aims to estimate the potential Shorea sp. standing stock in KHDTK Haurbentes by using tree sampling and circular plot method, which is Tree Sampling method consists of Six Tree Sampling, Eight Tree Sampling, and Ten Tree Sampling then to know the level of accuracy of both four sample units. The calculation result of the four sample units shows that Six Tree Sampling sample unit has the highest median value for total volume that is 724 710 m3/ha, bole volume is 563.705 m3/ha and basal area is 50.842 m2/ha, which is Sampling Error for total volume is 25.304%, 22.748% for bole volume, and 22.017% for basal area. Six Tree Sampling sample unit has faster working time which is 153.57 minutes for total time, or 6.31 minutes per plot. So Six Tree Sampling is standing stock estimation method that is most suitable to use in KHDTK Haurbentes compared than three other sample units

Judul: Struktur dan Potensi Tegakan Hutan Tanaman Meranti (Shorea spp.) di KHDTK Haurbentes Kabupaten Bogor
Abstrak: Structure and potency of forest stand meranti (Shorea spp.) in Forest Area with a Specific Purpose (FASP) Haurbentes is very interesting to be studied. FASP Haurbentes is a plantation forest area that built in 1940-1986. Variety compositions and vegetation covers of FASP Haurbentes are similar to the natural forest condition. Important Value Index (IVI) are used to measure the forest stand structure. IVI can be used to determine the compositions of vegetation type in various stage of growth level on the observation plots. Furthermore, forest stand potency needs to be estimated through volume estimation testing models that is already made. Research method use a line plots method. In the observation plots, forest stands structure in FASP Haurbentes forms an inverted J curve. Varieties that have the highest IVI in seedlings, saplings, poles and trees stage respectively are Shorea pinanga (47.1%), Shorea pinanga (80.1%), Shorea mecisopteryx (90.9%), and Shorea selenica (87.3%). Meranti Stands potency in FASP Haurbentes is in the amount of 434.66- 551.94 m3/ha. Meranti volume estimation model in FASP Haurbentes is V = 0.000234423 Dbh2.37.

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.
