Judul: Modeling wintering habitat distribution of migratory raptor “Oriental Honey-buzzards” based on satellite tracking data in West Java.
Abstrak: Raptors are at the top of the food chain, so their health depends on the health of the ecosystems they live in or migrate through. Thus, declines in raptor populations can indicate a problem in an ecosystem that raptors depend on. This study aims : 1) to build the distribution model of the OHB wintering habitat based on the data of satellite tracking in Talaga Bodas and surrounding areas; 2) to extrapolate the model for the entire province of West Java; 3) to analyze specific aspects of vegetation microhabitats in Talaga Bodas; 4) to develop wintering habitat management implications of OHB in West Java. This project was conducted in Talaga Bodas and surrounding areas then the model were validated in the other areas in West Java Province. Main methodology was combining satellite-tracking data of OHB with the GIS/remote sensing analysis, spatial modeling and vegetation analysis. Analyses were based on the comparison features (environmental variables) at the presence and pseudo-absence sites of OHB, which were detected from satellite-tracking data. Vegetation analysis to count Important Value Index and Diversity - Shanon Wiener Index in Talaga Bodas. The result, from 18 environmental variables, only 7 variables were detected as important variable for characteririzing the distribution of wintering habitat. Wintering habitat distribution model were predominantly influenced by slope 25%-40% (DS5), elevation 0-100 m (DE1), elevation 100-300 m (DE2), elevation >1000 m (DE5), forest (DFT), paddy field (DPF) and water body (DWB). Before the logistic regression model extrapolated in West Java, has been validated beforehand. Validation results showed that this model has an ommision error of 20,34%. 24 patches were detected from model extrapolation which is scattered in the region of West Java. The results of the vegetation analysis’s known that the core habitat biodiversity tend to have slightly less variable than the edge habitats. Results of this study suggested four implications for wintering habitat management of OHB.

Judul: Pengelolaan Lanskap Habitat Musim Dingin` Sikep Madu Asia (Pernis ptilorhyncus) Berbasis Data Satellite Tracking Di Kalimantan Tengah
Abstrak: Since 2003, 49 Oriental Honey Buzzards (OHB) had been satellite tracked and 47% (23 raptors) have selected Borneo Island as their wintering habitat which is composed by core and edge habitat. The objective of this study are to identify the landscape characteristics of wintering habitat, to compare core and edge habitat characteristics, to compare landscape habitat characteristics in West and South Borneo, and to recommend the landscape management plan of OHB’s wintering habitat. Landscape habitat characteristics were analyzed both in core and edge habitat using Principal Component Analysis (PCA) combined with GIS and t-student test was used to compare the habitat characteristics both in West and South Borneo. The first ten principal components (PCs) and thirteen PCs were retained, which are explained by 77.737% and 78.027% of the data variance in landscape characteristics of core and edge habitats. The basic characteristic between that habitats were not found. According to the landscape characteristics comparison, both in core and edge habitat, a landscape management plan was

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….
