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: Analisis Perubahan Garis Pantai di Pantai Barat Daya Pulau Ternate, Provinsi Maluku Utara.
Abstrak: A study pertaining analysis of shoreline change in southwestern coast of Ternate Island, North Moluccas Province has been conducted to analyze the shoreline change (abrasion and sedimentation) for 11 consecutive years from 2001-2011. The background of this study was based on the reality that southwestern coast of Ternate Island has undergone serious abrasion and sedimentation reaching the residential villages. There were no comprehensive studies yet conducted on how serious the coastal changes occurred. This study was aimed to analyze the wave transformation and shoreline change in southwestern coast of Ternate Island. The transformation of wave spectra in coastal environments is predicted with Nearshore (NSW modeul) MIKE 21 DHI models. Wave the paramters include the effects of refraction, nonlinear wavewave interactions, and parameterizations of wave breaking and bottom friction. Analysis was done applying two approaches i.e. using MIKE LITPACK DHI model and image digitation using Landsat Image 7 ETM+. Results of wave tansformation analysis is a waves coming from the west direction parallel to the Sasa Beach in station C, so the station C have a major impact of the wave transformation. Results of image analysis was used as comparison to validate the output of MIKE LITPACK DHI model. Overlying between results of model analysis and results of image analysis showed similar contour patterns of shoreline changes. Based on the results of model analysis, the highest abrasion level was found at station C (Sasa Beach) as far as 83.67 m and sedimentation occurred at station B as far as 45.69 m, whereas, based on the results of image analysis, the highest abrasion was found at station C as long as 27.14 m and sedimentation was concentrated at stasiun E as long as 24.09 m. The extent of abrasion and sedimentation was influenced by wave action occurred and activity of sand mining by local people in southwestern coast of Ternate Island.

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.
