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.

Judul: Pemanfaatan Data Penginderaan Jauh untuk Analisis Perubahan Lahan dan Curah Hujan terhadap Aliran Permukaan di DAS Ciliwung
Abstrak: The potential of flood occurrence in Jakarta has increased year by year. It caused by the presence of positive growth population that led the landuse change in the watershed (DAS) of Ciliwung. This landuse change has raised surface runoff in Jakarta and surrounding areas. This study aims to analyze the effect of landuse changes and precipitations to the surface runoff in Ciliwung watershed using Soil Conservation Services (SCS) method based on remote sensing satellite data. The results showed that the heavy rainfall has triggered the high runoff in the certain area. This heavy rainfall had various distributions in each sub-watershed so it was difficult to find runoff pattern in the watershed. Based on the soil hydrologic group (KHT), the forest area in upstream which has C type had lowest runoff coefficient (C) value than D type. The settlement and agricultural area in the central and downstream watershed had the highest C value. The decreasing of forest area in the upstream watershed was found around 1.7 % along with the increasing of settlement area and mix garden/plantation area in the central and downstream watershed that were 17.7 % and 10.4 %, respectively. Those conditions have caused the increasing of runoff coefficient around 24 % from year 2002 to 2012. The influence of ENSO phenomenon such as La Nina has caused high surface runoff in the Ciliwung watershed causing inundation/flooding in the downstream watershed area (Jakarta and surrounding areas) in those years.

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.
