Abstrak: The changes of surface run off and river discharge caused by landuse changes, could be estimated by watershed hydrology models. Soil and Water Assessment Tool (SWAT) model is a hydrology model that developed to predict effect of land use not only to water yield, but also sediment, pesticide contents, and chemical result of agriculture. Previous research of SWAT model application in Ciasem sub-watershed (5 659.6 Ha) by using global and local data show that the prediction average monthly discharge was appropriately match with measured average with the values of R2 and NS were > 0.51 and > 0.74 respectively. This research applied SWAT model to predict river discharge changes due to landuse change in the entire Ciasem watershed (67 794.8 ha). The purpose of this research is to predict changes in discharge due to changes in land use in the Ciasem watershed using SWAT model. Landuse changes in 2006-2011 occurred at forest plants being mixture of dryland farming, were 696.5 ha and forest plants being farms, were 131.8 ha. Simulation result of run off and discharge in landuse 2006 and 2011 and input climate 2006 showed it increase the runoff by 0.4 mm/month (4.8 mm/year) and discharge by 0.05 mm/month (0.6 mm/year). Land use simulation which changes mixture of dryland and dryland farming become forest plants reduce run off by 1.3 mm/month (15.6 mm/year) and discharge by 0.7 mm/month (8.4 mm/year) especially during wet months and increased discharge in dry months.

Abstrak: Increasing developed area and decreasing forest area lead to increase runoff coefficient that further to increase the stream discharge during rainy season and draught in dry season. The hydrological model can be applied to understand that phenomena. One of them is SWAT model. Application SWAT model in this research is focused only in rainfall transformation into discharge. Research is conducted in Ciasem Sub Watershed. The aim of this research is to know the dinamics of land use change and stream discharge in Ciasem Sub Watershed, also to know the effectiveness of SWAT Model for analyzing stream discharge by using available data in Ciasem Sub Watershed. The change of land use at 2003, 2006, and 2009 particularly happened on paddy field which was changed into a mixed agricultural dryland area of about 3253,8 ha, decreased runoff coefficient. Discharge estimation using SWAT model with measured rainfall at Curugagung Rain Station as input did not fit succesfully to measured discharge at Ciasem Sub Watershed outlet. Discharge estimation using SWAT model with simulated rainfall as input results better fitting to measured discharge at Ciasem Sub Watershed outlet with the value of R² > 0,51 and NS > 0,74. The result of the simulation showed that land use change of paddy filed to mixed agricultural dryland decreased runoff coefficient from 0,21 to 0,12 and also monthly maximum runoff discharge from 117,55 m3/s to 79,68 m3/s.

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.
