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 ptilorhynchus) Berbasis Satellite Tracking di Kawasan Talaga Bodas, Jawa Barat
Abstrak: Oriental Honey Buzzard (OHB) (Pernis ptilorhynchus) is one of migratory raptor that had been satellite-tracked since 2003. One of area which chosen by OHB was Talaga Bodas, placed in West Java. The objectives of this study were to identify and to compare the core and edge landscape characteristics of OHB‟s winter habitat in West Java, to compare characteristics of OHB‟s winter habitat in West Java with South Kalimantan, and to obtain the landscape management plan of OHB‟s winter habitat in Talaga Bodas area. Principal Component Analysis (PCA) combined with Geographical Information System (GIS) was used to identify and to compare the landscape characteristics. The results of this study were defined by twelve principal components (PCs) and eleven PCs, which were explained by 76% and 76,3% of the data variance in landscape characteristics of core and edge habitats respectively. The basic characteristics of core and edge ii habitats in West Java were related to the nearest distance by semi-plain area (3-8 % slope), the nearest distance by open land, and the nearest distance by paddy field. The difference of core and edge habitats in West Java and South Kalimantan was the conservation areas, where conservation areas of South Kalimantan placed in core habitat, whereas conservation areas of West Java area placed in edge habitat. Landscape management of winter habitat based on period (short and long term) was planned, and the ecotourism based on raptor migration was developed in Talaga Bodas area.

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….
