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: Pengelolaan Lanskap Habitat Musim Dingin Sikep Madu Asia (Pernis ptylorhynchus) Berbasis Satellite Tracking Di Kalimantan Tengah
Abstrak: Knowledge about landscape characteristic of oriental honey buzzard (OHB) in the context of wintering habitat is a prerequisite for understanding their wintering as well as managing their habitats. This study intends to identify landscape characteristic of wintering habitat of OHB (core and edge habitat) in Central Kalimantan and to recommend management plan of wintering landscape habitat of OHB in Central Kalimantan. Geospatial Information System (GIS) combined with Principal Component Analysis (PCA) was used for analyzing several environmental variables in order to identify the characteristic in both core and edge habitats. Nine principal components (PCs) were retained and explained by 78,7% and 77,9% of the data variance in landscape characteristic of core and edge habitat, respectively. T-Student test method was used to compare environmental variables between core and edge habitat and also to compare with previous study in South Kalimantan, then the result was significantly different. Management of wintering habitat can be planed within a certain period (short term and long term) and specific location (core and edge habitat).

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….
