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: Perubahan garis pantai dari pantai Teritip Balikpapan sampai pantai Ambarawang Kutai Kertanegara Kalimantan Timur
Abstrak: Shoreline change from coast of Teritip Balikpapan to coast of Ambarawang Kutai Kertanegara, East Kalimantan from 2000 – 2007 was analyzed by developing a model. Initial shoreline as an input for model was the result of Landsat image in 2000, and the shoreline from Landsat ETM in 2007 was used to compare the final result of model. The model predicts shoreline change due to along shore sediment transport generated by wave that brakes at the shoreline. The characteristics of broken waves was predicted by analysing wave transformation from off-shore sea where the wave was generated by winds. Sediment transport along the coast were mostlynortheastward as the main winds that blown toward the coast were mostly from the south. Simulation for 8 years showes that accretion more intensive in the northern part than those in the south. In general, shoreline shape resulting from model show a good resemblace to those from Landsat image in 2007. Discrepancies between the two shoreline shape occurred mostly at the upstream of the head land where results of model shows erosion but the images show the shoreline almost stable. This is perhap due to existance of mangrove that prevent erosion, but the effect of this vegetation is not included in the model.

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.
