Judul: Respon Antibodi Ayam Broiler yang Divaksinasi Newcastle Disease (ND) dan Diberikan Ramuan Herbal Fermentasi.
Abstrak: Ramuan herbal atau produk yang mengandung ekstrak tanaman digunakan sebagai alternatif feed supplement dalam usaha peternakan. Penelitian ini bertujuan untuk mempelajari pengaruh pemberian fermentasi herbal (ekstrak jahe, bawang putih, temulawak, dan kunyit) terhadap respon pembentukan antibodi pada ayam broiler setelah vaksinasi ND. Penelitian ini menggunakan dua jenis herbal yaitu herbal fermentasi lama (A) dan herbal fermentasi cepat (B). Sebanyak 140 ekor day old chick (DOC) dibagi menjadi tujuh kelompok dan tiap kelompok berisi 20 ekor. Kelompok II, III, IV, dan V dibagi menjadi dua kelompok (A,B) dan tiap kelompok berisi 10 ekor, kelompok A diberikan herbal fermentasi lama (A) dan kelompok B diberikan herbal fermentasi cepat (B). Pemberian vaksinasi dan tiap kelompok adalah sebagai berikut: kelompok I (divaksinasi tanpa herbal), kelompok II (diberi herbal tanpa vaksinasi), kelompok III, IV, V (divaksinasi dan diberi herbal), kelompok VI, VII (tanpa vaksinasi dan herbal). Vaksinasi dilakukan dua kali yaitu pada hari ke-3 dan hari ke-15 dengan vaksin live ND tipe B1 (GallivacTM Lasota) melalui air minum. Uji tantang dilakukan satu minggu setelah vaksinasi kedua dengan isolat lapang ND strain Sato (103.32 EID50/ml) melalui tetes mata. Sampel serum diambil pada usia satu hari untuk mengukur titer antibodi maternal, dua minggu setelah vaksinasi pertama, satu minggu setelah vaksinasi kedua, dan satu minggu setelah uji tantang. Titer ND diukur menggunakan uji HI. Nilai titer antibodi pada ayam yang divaksinasi berada dibawah 23. Rataan nilai geometric mean titer (GMT) ND pada tiap kelompok tidak menunjukan adanya perbedaan nyata. Hal tersebut mengindikasikan bahwa fermentasi herbal yang mengandung jahe, bawang putih, temulawak, dan kunyit tidak meningkatkan respon pembentukan antibodi setelah vaksinasi.

Judul: Studi Kemampuan Vaksin ND-IB Lived: Pembentuk Kekebalan dan Perlindungan terhadap Paparan Virus Newcastle Disease pada Ayam Pedaging
Abstrak: The objective of this study was to measure the antibody titer of broilers were vaccinated with lived ND LaSota-IB H120 vaccine, and to observe the clinical signs and pathological lesions on challenged group. As much as 60 commercial Day Old Chicks were used in the experimental. Twenty chickens were bleed at day one to measure maternal antibody against Newcastle Disease (ND) using Hemaglutination Inhibition (HI) Test. The remaining fourty chickens were divided into four groups. Each group consisted of ten broilers. Group K1 and K2 were unvaccinated. Group K3 and K4 were vaccinated on the 2nd day according to the manufacture procedure. Challenge was carried out on 14th day (12th day post vaccination) to group K1 and K3 with ND Indonesia isolate virus. Blood samples from unvaccinated and vaccinated group were taken on 7th, 14th, and 22nd day. The result showed that chickens had high maternal antibody titer. The combination of intranasal and oral vaccination was able to produced protective antibody against ND viral infection. Vaccination was able to reduced lethargy and petechiae cecal tonsil. The clinical signs and pathological lesions were more severe on unvaccinated group.

Judul: Klasifikasi Spasial untuk Objek Spasial di Kota Bogor
Abstrak: Various spatial objects in Bogor City have caused a significant increase of spatial data in Bogor City. These spatial data needs to be processed and analyzed using spatial data mining technique, which is able to extract the knowledge or patterns in the spatial database. This research extracts the patterns of terminals, stations, railroads, rivers, roads, and landuse characteristics using one of the spatial data mining techniques, namely spatial classification. In this research, the spatial relations between an object and its surrounding is determined using topological relations, with spatial operations such as contains, overlaps, equals, disjoint, intersects, within, crosses, and touches. The result of spatial classification accuracy using C4.5 algorithm is 72.117%. From this spatial classification result, the characteristics of spatial objects in Bogor City can be identified based on spatial operations.
