Judul: Perubahan penggunaan lahan DAS Citarum dan dampaknya terhadap suplai air irigasi (studi kasus : periode tahun 2002-2009)
Abstrak: The research used secondary data between 2002 to 2009 in PJT II Jatiluhur and Citarum-Ciliwung watershed Management Agency. Generally, this research was done in Citarum watershed area, West Java province, from August to October 2010.The research aims to investigate: 1). Land use change in Citarum watershed area; 2). Effect of land use change on water yield; 3). Changes in water yield and its impact on irrigation needs; and 4). Effect of irrigation water supply to changes in rice acreage. According to the digital citra analysis, Citarum watershed area that located above Jatiluhur dams has changed land use (450.649 ha) between 2002 and 2008. In agriculture areas land use change significantly increased from 59.76% in 2002 to 70.52% in 2008. Changes in water results continue to demonstrate the value decreases with increasing area of agriculture following the equation ym = 2987.74-0.00766887x2 (x2 is an extensive agricultural area in ha; ym is the result of water in million m3/th). Decrease in water yield has not been an adverse impact on irrigation needs, seen from an index value of the use of water in the reservoir continues to decline, resulting in increased efficiency of reservoirs. Index decreased use of water reservoirs affected by the increase in annual precipitation, so as to reduce the effects of the decline that occurred in the water. Changes in area of rice fields terjadididuga because of land conversion to non-agricultural activities that are not triggered by lack of water.

Judul: Pengaruh perubahan penggunaan lahan terhadap karakteristik hidrologi DAS Citarum Hulu
Abstrak: Land use change in a certain area will affect hydrologic characteristic there, so that it can be used as a reference whether the area is critical. This research objective is to study the effect of land use change to hydrologic characteristic of Upstream Citarum Watershed. There are 5 sites observed in Upstream Citarum watershed: Cikapundung, Citarik, Cirasea, Cisangkuy, and Ciwidey. This research was carred out by analyzing data of rainfall, discharge, and runoff, and by observing land use map. The result of analysis was then linked and matched to the data of land use descriptively. The result of this research showed that Cisangkuy sub-watershed was the worst due to its hydrologic characteristic. It can be seen from its increase in discharge and relatively high runoff coefficient in 2008, compared to ones of 2003. This condition was caused by land use changes happened there, which were decreasing primary land dry forests area, and increasing settlement area and wet rice field.

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.
