Judul: Correlation of Massart Architecture Model for Agathis dammara L.C.Richard with Soil and Water Conservation at 27th plot RPH Gambung PHBM’s Area, KPH Bandung Selatan.
Abstrak: Agathis dammara L.C. Richard is plant that shaded Coffea arabica L. in the Pengelolaan Hutan Bersama Masyarakat (PHMB)'s ecosystem in South Bandung. Agathis dammara L.C. Richard with Massart's architecture has the contribution toward the soil and water conservation within its ecosystem. The purposes of this research are: 1) Determining the parameter’s scale of soil and water conservation (rain fall, stem flow, through fall, surface run-off and erosion) in the PHBM’s ecosystem, 2) determining the correlation between the parameter of soil and water conservation in PHMB's ecosystem, 3) determining the role of plant architecture model Massart of Agathis dammara L.C. Richard toward soil and water conservation in PHBM’s ecosystem. The results shows the scale of rain fall, stem flow, through fall, surface run-off, and erosion of Massart architecture model of Agathis dammara L.C.Richard in a row are 981.6 mm, 17.905 mm, 515.86 mm, 45.49 mm, and 5.314 ton/ha/year. Biplot Analysis shows the positive correlation among the parameter of rain fall, stem flow, through fall, surface runoff and erosion. Therefore, it can be concluded that the Massart’s Architecture model for Agathis dammara L.C. Richard is good for supporting the soil and water conservation of PHBM’s ecosystem where stem flow is the most closely related to the erosion.

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: 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.
