Judul: Variability of chlorophyll-a and some oceanographic parameter in related with monsoon, ENSO and IOD at the Banda Sea.
Abstrak: The Banda Sea is a very fertile area because it’s a potential area of fisheriesfield, and is one of the largest fishing areas in Indonesia. The Banda Sea is influenced by external factors such as El Nino Southern Oscilation (ENSO), the cross-currents of Indonesia (Arlindo) and season. Furthermore the Banda Sea can also be called “the heart of “ current flow in the waters of Indonesia, as well as “the capasitor of ”water mass transport to the Indian Ocean and one of the areas that upwelling occurs where the water surface temperature can reach down to 25oC, was caused by the cold water from the bottom layer is elevated to the upper layers. The purpose of this study was to analyze the influence of variability of sea surface height parameter, sea surface temperature and chlorophyll-a; to analyze the influence of ENSO and Indian Ocean Dipole (IOD) has related with the variability of sea surface height (SSH), sea surface temperature (SST) and chlorophyll-a; and to search the internal forcing that causes the variability. The research was carried out in February 2011-June 2012, located in the Banda Sea with position between 3.5-7.5oLS and 124-133oBT. The data used are the sea surface height, sea surface temperature, chlorophyll-a, which are derived from MODIS-Aquamulti-sensor satellite data from 2002 to 2012, and surface wind data obtained from the European Centre for Medium-Range Weather Forecasts (ECMWF). The data were analyzed by using the Ferret software version 6.0 in order to show the view variability of seasonal cycle and it’s annual cycle. Then the wind data, the Nino index 3.4 and Dipole Mode Index (DMI) will be analyzed by using wavelet methods in Matlab 2010 software to show annual cycle in the format of continous wavelet transform (CWT) and cross wavelet transform (XWT). In the variabilityof monthly average sea surface height from 2002 to 2012, there were the maximum value in March (transitional season I) with the value is 0.1498 m. The sea surface height of minimum in August with the value is -0.02 m. The Variability of sea surface temperature is maximum in December (west season) with a value is 30.68oC. The lowest temperature value found in August with avalue was 26.67oC. The value of chlorophyll concentrationat west ranged from 0.125-0.145 mg/m3 and chlorophyll concentration value at transitional season II ranged from 0.125 to 0.146 mg/m3. The chlorophyll concentration values at east season are 0.285 to 0.458 mg/m3 and chlorophyll concentration value at transitional season I range between 0.372-0.134 mg/m3. The highest value of the chlorophyll concentration which occurs on east season in August with a value of 0.458 mg/m3 and the lowest at west season in December with a value of 0.125 mg/m3. Zonal wind circulation patterns in January (west season) with speed 5.32 m/sec is more stronger because occurrence of the southwest monsoon winds are blown strong whereas in July (east season) the wind speed are weaker at -4,987 m/sec. The meridional wind circulation patterns in July (east season) are more powerful with a value 5.252 m/sec, where happened is south eastern wind monsoon while in February

Abstrak: The Indian Ocean Dipole Mode (IOD/IODM) is an oscillation of the interaction between atmosphere and ocean system. IODM comprises of bipolar structure that characterized by the difference of sea surface temperature to normal. This phenomenon provides important influence to the several parameters of oceanographyc. While the positive event of IODM, during southeast munsoon (June to October), southeasterly wind from Australia generates upwelling, bringing cooler waters and increased nutrients to the surface along the southern coast of Java and Sumatera and its condition has been increasing chlorophyll-a concentration. The objectives of this study is to know the variability of chlorophyll-a along the southern coast of Java and Sumatera on positive IODM event. The sea surface temperature (SST) images taken from thermal sensor of Advanced Very High Resolution Radiometer-National Oceanic and Atmospheric Administration (AVHRR-NOAA) has been used to detect the cooler water as upwelling indicator. We investigated the spasial and temporal variability of chlorophyll-a along the south coasts of West Java and Sumatera from September 1997 to December 2009, by using the data of the Sea-viewing Wide-field of view sensor (SeaWiFS) of Sea Star satellite. The results shown that formation phase of IODM in transitional season I (May), while the strengthening of the South Equatorial Current followed by early cooling of the SST. The maturation phase in the southeast monsoon (June to August) and decay phase in November was followed by warming of the SST. At the Southeast monsoon (June to August), there is a visible presence of upwelling in the south of Java and western coast of Sumatera. Upwelling with highly intensity was founded in the southern coast of Java and western part of Sumatera on strong positive IODM event assosiated with intermediate of El Niño event, 1994. Higer chlorophyll-a concentration corresponds very well with monsoon-generated upwelling during the Southeast monsoon cycle. During the peak of anomalous easterly winds on strong positive IODM event (1997 and 2006) were induced strong upwelling. This event produced higher chlorophyll-a concentration that extended further northwest-ward along the Sumatera coast. The impact of upwelling while the IODM positive event on pelagic fish catch, likely follow the temporal variability in chlorophyll.

Judul: Telaah Histopatologi Urolithiasis Pada Kucing
Abstrak: Urolithiasis adalah suatu keadaan dimana ditemukannya batu di dalam saluran urinaria. Batu tersebut dibentuk dalam pelvis ginjal dan bergerak turun sepanjang ureter kemudian masuk ke dalam vesika urinaria dan uretra. Penulisan ini bertujuan untuk mempelajari lebih dalam secara histopatologi tentang kasus kematian seekor kucing dengan urolithiasis yang dinekropsi di Laboratorium Patologi FKH-IPB. Pemeriksaan patologi anatomi menemukan adanya fokal atelektasis paru, dilatasi ventrikel kiri jantung, hidrothoraks, hidroasites, ginjal pueat dan batu-batu berbagai ukuran dengan diameter 0,1-0,5 em pada vesika urinaria yang berdarah. Pada pengamatan histopatologi menunjukkan pembendungan semua organ, nephritis interstitialis kronis disertai bentukan mikrokista dan endapan mineral pada lumen tubuli dan sistitis nekrotik disertai pendarahan yang meluas. Pemeriksaan pada organ paru-paru ditemukan lumen alveolus sebagian mengempis dan sebagian lagi meluas. Dinding alveol menebal akibat adanya akumulasi eritrosit. Sedikit koloni bakteri tampak dalam lumen usus, bercampur dengan epitel usus yang terlepas di ujung viii. Hati mengalami pembendungan, ruangan sinusoid tampak meluas. Beberapa megakariosit tampak di dalam pulpa merah yang menunjukkan adanya aktivitas hematopoetis. Organ jantung tidak menunjukkan adanya perubahan histopatologi yang spesifik.
