Judul: Variabilitas Arus di Sekitar Selat Sunda Tahun 2007-2010 dari Hasil Model INDESO
Abstrak: Model output of high-resolution (1/12°) ocean general circulation model from INDESO project between 2007-2012 were used to investigate the structure and variability of currents at two locations around the Sunda Srait, one location is in Java Sea (JS) and the other is in Indian Ocean (IO) side. Model sea surface height (SSH) is validated with altimetry data, which shows a high correlation coefficient of 0.90 in the IO and 0.76 in JS. In general, both model and altimetry data indicate that SSH in JS is always higher that found in IO. However, between November-January each year, there exists a reversal flow northward in Sunda Strait, which may be related to arrival of coastally trapped Kelvin waves. An intensification of current appears near surface layer both in JS and IO. Analysis of power spectral density energy exhibits a wide range of current variability from intra-seasonal, semi-annual and annual time-scales. Power density energy of zonal current component is much stronger that that meridional component, and amplitude of energy is much stronger in IO it show that current in IO is stronger than JS. Cross correlation analysis show that there is strong relation between between JS and IO currents fluctuation which showed by coherence value between two areas of 0,99.

Judul: Simulasi Arus Musiman di Perairan Indonesia
Abstrak: ROMS-AGRIF INDO03 model configuration with medium-resolution 1/3° has been developed to examine general circulation of Indonesian Sea from 95 °E – 14 °E and 20 °S – 20 °N. Wind driven and atmospheric flux obtained from climatological data COAD (2005), and climatological data of seawater properties obtained from the World Ocean Database (2006), meanwhile lateral boundary driving force was used from the simulation results Drakkar INDOORCA05 climatology (1970-2003). This study aim to examine annual current circulation of Indonesian sea. The 10th year simulation results with a daily average value were used in this study. A correlation betwen sea surface level of the model and sea surface level from altimetri climatology satelit (2000-2010) run from the model showed a fairly high value (0.5-0.9). The mean flow surface current in the Indonesia sea is more influenced by the monsoon winds. In the Indian Ocean flow Java Coastal Current and South Equatorial current. In the North of Papua mean flow of surface current flowing to westward which is part of the New Guinea Coastal Current. Seasonal current from modeling results indicate the direction of flow in the West Season from West to East, opposite the East season from East to West. Vertical structure current in the Java Sea and Strait Karimata flowing from surface to sea floor is relatively homogeneous, in relatively shallow waters that are still affected by seasonal current until the sea floor. Vertical structure current in the Makassar Strait, Banda Sea, and Indian Ocean there is a difference in the surface layer and thermocline layer, because it waters so that the seasonal current happend only on the surface and Arlindo that happend in the thermocline layer. Seasonal variation seen in the difference in surface temperature and salinity on the West and East season.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
