Judul: Studi geomorfologi pulau ternate dan penilaian resiko longsor
Abstrak: Ternate Island is an active volcano (Gamalama Volcano) where the capital city of Ternate Municipality located. The island has however highest population density in compare to other regencies in North Maluku Province. The population tend to grow by time and the demand of land for settlements increase following the population growth. Some of the lower part of volcanic slope has recently been occupied by settlement and unfortunately it triggered landslides in recent days. The purposes of this research are to study geomorphology of Ternate Island and to analyze landslide hazard and risk. To achieve this purposes the satellites imageries, i.e. Geo Eye (Google Earth) and SRTM imagery, were used for geomorphological visual interpretation. The landforms were used as a parameter for landslide hazard analysis along with other parameters such as slope steepnes, soil texture, and land use. The landslide hazard then used together with community vulnerability parameter to analize the landslide risk. In this study, the method of weighting and scoring were applied to each parameter and its variables to assess landslide hazard and risk, and all of data analyzed using Geographic Information Systems. The results showed that the geomorphology of the study area is dominated (71.15%) by volcanic landform following the morphogenesis of Ternate Island, while the rest are fluvial landform (26.1%), marine landform (2.5%), and anthropogenic reclamation landform (0.25%) occupied by settlements and commercial area. Based on geomorphological conditions, 18.2% of study area considered safe area from landslide hazard, but 23.7% classified as low hazard, 29.8% as moderate, and 28.1% as high hazard. In compare to landslide susceptibilty assessment result, it appears that land use changes in the study area are quite a major effect provoking landslide hazard. The result of landslide risk analysis showed that 96.3% of study area is far from risk, but 1.16% classified at low risk, 2.2% at moderate risk, and 0.44% at high risk. In relation of these zones of risk, there are of about 2.0221 houses at low risk area, 4.041 houses at moderate risk area, and 826 houses at high risk area. All these numbers of risk can however be increased by time when the value of each parameter change. Therefore monitoring of land use changes, particularly for residential, is very important for study area, especially in relation to the government mitigation program and spatial planning.

Judul: Pemetaan Kawasan Rawan Bencana dan Analisis Resiko Bencana Tanah Longsor dengan Sistem Informasi Geografis (SIG) (Studi Kasus Kawasan Kaki Gunung Ciremai, Kabupaten Majalengka)
Abstrak: Landslide disaster is one of the natural disasters that often occur in Indonesia and is generally common in mountainous regions, the rainy season and is closely related to natural conditions such as soil type, rock type, rainfall, land slope and land cover. The aim of this study is to mapping hazard landslide areas and to analyze the risk of landslides in the Ciremai foothills region Majalengka district. Puslittanak (2004) is using to be a model of analyzing landslide susceptibility prediction in study area, the formula is Total Score = 0,3 FRain Falls +0,2 FGeology +0,2 FLand Slope +0,2 FLand Cover +0,1 FSoil Types. Risk analysis was analyzed by quantitative models based on research of Alhasanah (2006) through the overlaying property map score (infrastructure map, road map and land cover) with landslide vulnerability map. In study area, low landslide susceptibility class dominated by flat topography, the dominant rock type is Qa (Aluvium), soil type is Latosol and rainfall intensity 2500-3000 mm/year. Medium landslide susceptibility occur in flat to a relatively steep slope with the type soil dominated by Andosol and level of rainfall intensity is 2500-3000 mm/year. At high landslide susceptibility, dominated land cover is forest with steep topography (15-30%), rock type is dominated by Qvu and the soil type is Andosol with rainfall 3000-3500 mm / year. Very high vulnerability to landslides mostly located in forest areas with very steep slope (>45%), high rainfall intensity 3000-3500 mm/year and dominated by Qyu rock type and Andosol soil type. Based on the analysis of vulnerability map, in area study obtained low vulnerability covered area 2160,45 hectares, medium vulnerability with covered 15319,71 hectares, 21992,49 hectares of high landslide vulnerability and very high vulnerability covered 6191, 91 hectares. Very high vulnerability mostly located in Argapura with 2811,78 hectares (45,41%). Based on the analysis of risk maps, the area of research has a low risk area with a wide level of 13212,36 hectares (28,93%), medium risk level covered 31507,38 hectares (69,00%), high risk level covered 806,94 hectares ( 1,77%) and very high risk level covered 137,88 hectares (0,30%). Areal distribution of very high risk level areas are the largest in the Maja with covered area 32,67 hectares (23,69%).

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.
