Judul: Komputasi Data Multibeam Sonar untuk Perencanaan Pembangunan Jembatan Selat Sunda.
Abstrak: The bridge is a construction for marine transportation facility. The Indonesian Government initiated will carry out the largest projects to build a bridge at Sunda Strait on 2014. The bridge construction will take quite a long time, therefore effort should be made to obtain relevant information to the construction of the bridge is running efficiently. The purpose of this research is to apply the instrument hydroacoustic of multibeam sonar to measure sea water depths and to map the distribution of sediment types. Survey conducted in Sunda Strait on the coordinates of 5052’-6002’S and 105045’-106054’E. Data acquisition done by using hydrostar software. Bathymetry data was processed with Caris HIPS&SIPS. Data amplitude was processed with MB Systems to make sediment classification. Tides in research area is mixture type, where tidal type is suitable for the construction of the bridge was held because tidal type has a relatively small effect on the scatter and distribution of sea floor sediments. Depth research area have range from 17,5-175 m, there are several ridge sea that can be used as a laying pole bridge. There are two locations considered suitable on location 1 and 2, where both the location is ridge sea with depth range17-35 m. The type of sediment obtained by processing data amplitude and core of sample sediment. The types of sedimen in research area are silty sand, sandy silt, sand and rocks. Sediment is dominated by sandy silt with percent coverage of 49%. Location 1 and 2 have a sandy silt sediment. The pole type that fits is the pillar of the prisoner's coherency between the pole to the ground (Friction piles), when the pole to stick on the ground with powerful high friction values such as sand, then load that is accepted by the mast will be withheld based on friction between the pole and the land around the pole.

Judul: Aplikasi Multibeam dan Side Scan Sonar untuk Mendeteksi Target Runtuhnya Jembatan Kartanegara di Kutai Kalimantan Timur
Abstrak: Kutai Kartanegara bridge is a suspension bridge crossing over Mahakam River in East Kalimantan. This bridge is to facilitate between Tenggarong and Samarinda city. However, on 26 November 2011 Kutai Kartanegara bridge damaged. Thus, pushing many people took to the field for the evacuation and search for the cause of the accident. The objectives of this research are to find out bottom information such as water depth and position of the target from the collapsed bridge to assist in the evacuation process. Multibeam and side scan sonar (sss) is a hydroacoustic instrument capable of detecting bathymetry and determine the condition of the sea bottom. In this survey, the data acquisitions are conducted by using a Multibeam Reson Hydrobat and SSS EdgeTech 4200. Bathymetric data were processed using PDS 2000 and a Caris HIPS & SIPS 6.1 software, side scan sonar data were processed with SonarWeb and a Caris HIPS & SIPS 6.1 software, and analism of the amplitude value from the target with the help of SeiSee and a Xtf2segy software. The results of the research are bathymetry map with depths ranging from 4.07 meters to 58.15 meters and found the targets of sea bottom that have the shape of frame of the bridge, target-shaped box / square, strap-shaped targets, target-shaped small bumps, and target objects straped. The mosaics of acoustic wave reflection intensity were resulted from the sea bottom and have been obtained the estimation value of the highest amplitude from the target shape of frame bridge is 7200 – 7974 mV and the lowest of the substrate around the strap-shaped target is 258-454 mV.

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.
