Judul: Analysis and predictive catch for skipjack tuna (katsuwonus pelamis) in buton region waters south east sulawesi
Abstrak: One of the effort to predict the Skipjack catch is determined by environmental factors; for instance the local climate (wind speed, obstruct wind, rainfall, sun intensity, air temperature), the global climate (ENSO) and oceanography factor (Sea Level Temperature). This study was conducted to determine the affecting of climate and oceanography factor to Skipjack catch. The data is analyzed by using the discriminant Analysis. The result of this research showed that the most of affecting factor toward the catch are wind obstruct and ENSO. The accurate of dscriminant analysis in determining the catch category show ed that value of the model is 84% and to predict of cross validations is 86%. The Correlations of Wind obstruct and ENSO to the catch are described by function 1 : Z1 =22.088+0.009 X1+ 0.754 X2, function 2: Z2 =-1,557+0.009 X1+1.013 X2 where Z=Skipjack catch; X1=wind obstruct at the second mounth for every kwartal X2=ENSO at the second mounth for every kwartal.

Judul: Sustainability of skipjack katsuwonus pelamis fisheries in Indonesian Exclusive Economic Zone (IEEZ) of Indian Ocean at Southern Coast of East Java
Abstrak: Indonesian exclusive economic zone of Indian Ocean at southern coast of East Java includes in WPP-RI 573 which has potential biological resources to be utilized for economic development. Specific oceanographic condition has caused the regions relatively more fertile than other regions. An abundance fishery resources in the region is skipjack which has a sufficiently high economic value. Utilization rate of the species is assumed of being moderate thus enabling further increasing in its utilization. One type of fleet used to exploit skipjack resources in WPPRI 573 is sekoci boat based in PPP Pondokdadap, Malang Regency. The fleet number has showed a significant increase during 2001-2010. Size of the vessel includes in medium category and still uses traditional fishing gears (hand-line). Sekoci boat has been reliably used to catch fish at a distance of 50-200 miles, with catching period 8 to 12 months every year in areas fitted with a fish aggregating device. Research objectives were to analyze the conditions of oceanographic factors, skipjack stock biomass, linkages between oceanographic aspects and stock biomass, fisheries sustainability status on ecological, economic, technological, social and institutional dimensions, as well as management strategy of the fisheries through priorities setting based on multidimensional sustainability status. Research results showed that wind monsoon affected vertical and horizontal distribution of sea surface temperature (SST) and chlorophyll-a concentration. Distribution of those parameters during eastern monsoon favored the abundance of skipjack population compared to that in western monsoon. CPUE fluctuations trailed monsoon patterns, with higher values in the eastern monsoon than in the western monsoon. Fishing season peak occurred in July to October annually. During the eastern monsoon SST decreased while concentration of chlorophyll-a and CPUE values tended to increase. Contrary, during the western monsoon SST increased and chlorophyll-a concentration as well as and CPUE tended to decrease. Furthermore, sustainability index for each dimension indicated that ecological dimension included in sustainable category, followed by technological dimension in moderate category. Sustainability index of institutional, economic, and social dimensions included in less sustainable category with the lowest index on social dimension. Multidimensional index indicated that overall status of skipjack sustainability in IEEZ at southern coast of East Java was moderate which required arrangement of various sensitive attributes. Smart analysis result showed policy priorities for social dimension followed by institutional and economic dimensions. The highest score attributes of the dimensions were consecutively business ownership, enforcement of rules, and environmental awareness. Application of policy priorities would result in increases in sustainability index with higher values after application of the policy.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
