Judul: Korelasi arsitektur pohon model rauh dari jenis pinus merkusii junghuhn & de vriese dengan konservasi tanah dan air di area PHBM yang ditanami coffea arabica L. RPH Gambung KPH Bandung Selatan
Abstrak: Trees in CBFM (Community-Based Forest Management) ecosystems are suspected to modify rainfall interception, infiltration and as a consequence, erosion. Their effect urges to be assessed and modelled in various conditions of soil and density of vegetation. The most important parameters that affect the soil water balance and erosion were identified as being the total input of water (throughfall and stemflow) to the ground and the runoff ratio. This research was studied correlation of erosion on rainfall, throughfall, stemflow, and runoff. The aims of the research were to : (1) identify architecture model of pine tree, (2) observe throughfall, stemflow, runoff, and soil loss values, (3) study impact of architecture model of pine tree to water and soil conservation. Runoff and soil loss data were collected for thirty-four days of rainfall from three runoff plots situated on a 36% uniform slope areas. Three fields are studied on this research ; pine forest planted with Coffea arabica L., natural vegetation dominated by Altingia excelsa Noronha., and cultivated land. Erosion measurement was conducted at plots 12 long and 4 m wide. The result of the research indicates that P.merkusii and A.excelsa have same tree architecture, Rauh model. Result of loading plot analysis indicate that correlation between throughfall, stemflow and runoff with rainfall and erosion are positive. Forest planted P. merkusii and natural vegetation dominated by A. excelsa prevent or decrease the risk of soil erosion. The greatest amount of sedimentation was observed in cultivated land (55.99 ton/ha/yr). In conclusion, important to consider the type and model of tree architecture which will be planted so as to conserve soil and water and to keep the ground cover to decrease soil erosion.

Judul: Korelasi model arsitektur pohon dengan laju aliran batang, curahan tajuk, infiltrasi, aliran permukaan dan erosi (suatu studi tentang peranan vegetasi dalam konservasi tanah dan air pada sub-DAS Cianjur Cisokan Citarum Tengah)
Abstrak: Every tree species which grows at an watershed has a certain architectural model that is why it has also different capacity in transforming rainfall directly as stemflow, througfall an interception. The research was conducted with purpose of (1) identifying architectural model of thirty trees, their IVI at each zone and water conservation and (2) easuring litter production of thirty tree species growing at the upstream of Cianjur watershed in the GPNP.

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.
