Judul: Analisis Perubahan Penggunaan Lahan dan Debit Aliran Sungai Ciwidey, Jawa Barat
Abstrak: Population growth and rapid regional development in Ciwidey Watershed lead to very intensive land use changes that icrease flooding risk in the region. This study aimed to identify land use changes and its effects on river discharge in Ciwidey Watershed. Land use changes that occured during 1994 up to 2005 periode werw primary forest, secondary forest, industrial zones, mixed garden, dry land agriculture, plantations, settlements, and ricefield. Most of land use changes occurred in the period 1997 to 2001. During that period, the primary forests and secondary forests esperienced the largest change where respectively 742.3 ha and 471.1 ha were converted to other land uses. The maximum discharge are Ciwidey river in 1997 and 1998 were 27.0 m3/s and 33.1 m3/s with run coefficient of respectively 0.69 and 0.84 . The high runoff coefficient was allegedly associated with dominant land use changes that occurred in the periode of 1997 to 2001. There are other factors that might contribute to the high discharge and high magnitude of runoff coefficient, namely the impact of El Nino and La Nina which occurred in 1997 and 1998. El Nino causes drought season and La Nina causes long rainy season.

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.

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.
