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: Rainfall-discharge transformation in a watershed is an indicator that shows the capability of watershed to control water yield and flood. During 2007-2012, in the region of Jakarta and Bogor show that the rainfall transformation into runoff in Ciliwung watershed including upper watershed in Ciliwung remains high. Knowledge about rainfall transformation in Ciliwung upper watershed are needed. Hydrological models are possible to estimate that rainfall transformation. One of the models that currently often be used is SWAT (Soil Water Assessment Tools) model. The prediction of discharge with SWAT model in Ciliwung upper watershed has satisfying result with coefficient of determination (R2) 0.53 and NSE 0.73. Landuse changes from 2009 to 2012 has decreased the coefficient of measured runoff from 0.76 into 0.22 and based on the estimated runoff has decreased from 0.9 into 0.7. Based on the best scenario of the landuse changes is to apply soil and water conservation in agricultural land with contoured tillage and improving mixed agriculture with agroforestry system, rainfall – runoff transformation runoff decreased from 1763 mm/year into 1565.2 mm/year and the discharge decrease from 4367.0 mm/year into 4350.9 mm/year.

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.
