Judul: Evaluation Land Use Changes and The Effect on The Hydrological Characteristics of the Upper Citarum Watershed
Abstrak: Currently mayority of watersheds in Indonesia have suffered a lot of decreased function in maintaining water availability and environmental health, one of which is citarum watershed. Land use changes in the Citarum watershed are very intensive, especially in the upstream part. The upstream watershed plays an important role as a water absorbtion area and a buffer zone for the downstream area. The research was conducted in the upper Citarum watershed covering an area of 175,158.9 hectares with the outlet at Nanjung stream monitoring station, which aims to analyze land use changes on hydrological characteristics in the upper Citarum watershed, and formulate land use direction in the upper Citarum watershed that are able to preserve the hydrological function of the watershed. The research were devided to; (1) visual interpretation of SPOT image data; (2) analysis of land use changes; (3) hydrological response analysis of river discharge; (4) analysis of the effect of land use changes on river discharge; (5) analysis of the suitability of upper citarum watershed spatial pattern to spatial plans of West Java. Spot image interpretation can be done well as shown by the Overall Accuracy (OA) coefficient of 93.33% and Kappa Accuracy (KA) of 90.6%. The results of the analysis of the map of land use changes in the upper Citarum watershed in the period 2009 - 2018 showed an increase in vacant land (+95%), developed land (39.7%), rice field (+13%), and plantations (+6.4%). The increase was accompanied by a decrease in bushland (-60%), rice fields (-17.4%), and forests (-5.5%). The percentage of suitability of the existing land is 59.6% suitable and 40.7% not in accordance with the spatial pattern of the West Java spatial plans. The results of hydrological response evaluation show that the Ciwidey, Cisangkuy, and Cihaur sub-watersheds are classified as first priority to be restored it’s hydological response entirely. Second Priority is Cirasea, Cikeruh, and Cikapundung sub-watersheds, where efforts to restore hydrological response are gradual. Where as the Citarik sub-watershed is classified as third priority that the hydrological conditions must be maintained. The application of land conservation that combines vegetative and physical conservation is aimed at types of land use that do not match the area's spatial pattern. The management and utilization of agricultural and plantation land by applying agroforestry systems, intercropping and terracing along with the application of a zero runoff system in built-up land is expected to improve the hydrological response of the Upper Citarum Watershed.

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.
