Judul: Analisis Faktor Pendorong Perubahan Penutupan dan Penggunaan Lahan di Daerah Aliran Sungai Cimandiri dan Cibuni
Abstrak: North region West Java’s development around Jakarta is constantly accelerating. The development itself has caused many problems which are happening until today. However, the development in south region of West is very slow, although there are many potential land for development. Two watersheds which are located in south region, namely Cimandiri and Cibuni watershed are less developed than the watersheds in the north region of West Java. Therefore, supporting landscape planning to explore the watershed resources potential and landscape management to consider the environmental impacts for supporting the Low Carbon Societies (LCS) movement is needed. The purposes of this research are to analyze land use and land cover changes, and to determine the driving factor of the changes in Cimandiri and Cibuni watershed. The used methods are supervised classification and Logistic Regression Analysis (LRA). The results are land use map of Cimandiri and Cibuni watershed in 1978, 1995/6, and 2012. Farm field, forest, and bushes field are dominating in both watersheds. The driving factors for Cimandiri watershed show that there are four factors while there are three factors in Cibuni watershed that are significantly affecting land use and cover change.

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: 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.
