Judul: Evaluasi Antibodi Asal Induk (Maternal Antibodi) pada Kuning Telur Asal Ayam Single Comb Brown Leghorn yang Divaksinasi  dengan Vaksin Avian Influenza H5N9
Abstrak: Penelitian ini bertujuan untuk mengetahui tingkat kekebalan asal induk (maternal antibodi) pada kuning telur asal ayam yang divaksinasi H5N9 dan diuji dengan virus standar avian influenza H5N1. Penelitian ini menggunakan hewan coba berupa ayam petelur strain Single Comb Brown Leghorn berjumlah 6 ekor. Semua ayam divaksinasi dengan vaksin inaktif H5N9, setelah sebelumnya dilakukan uji HI dengan menggunakan virus H5N1 sebagai virus standar untuk memastikan bahwa ayam-ayam tersebut memiliki titer antibodi terhadap H5N1 yang rendah atau tidak memiliki antibodi sama sekali. Telur dikoleksi setelah titer antibodi yang terbentuk di dalam serum mencapai 26. Imunoglobulin Y diperoleh dengan metode purifikasi menggunakan PEG-Kloroform. Rataan hasil penghitungan titer IgY H5N9 dengan menggunakan uji HI tiap minggu dari minggu ke-1 sampai minggu ke-5 adalah 21, 20.75, 20, 21, 20. Berdasarkan hasil tersebut menggambarkan bahwa vaksin H5N9 pada induk tidak memiliki kemampuan untuk memicu terbentuknya antibodi maternal pada kuning telur atau IgY yang kebal terhadap H5N1.

Judul: Studi Kemampuan Netralisasi Antibodi Anti AI H5N1 Asal Induk Dalam Kuning Telur Ayam Yang Divaksinasi Berbagai Vaksin AI H5N1 Komersial Terhadap Virus AI H5N1
Abstrak: The research was designed to study the capability of antibody anti H5N1 Avian Influenza from egg yolk to neutralize H5N1 AIV. Twenty five hens were divided into five groups, one group as a control group were unvaccinated and four other groups were vaccinated with H5N1 AI inactive vaccine produced by several Indonesia vaccine company. Four H5N1 AI inactive vaccine code VS, VC, VV and VM were vaccinated twice for each group with a month, interval. Group 2 were vaccinated with vaccine code VS, group 3, 4, 5 were vaccinated by vaccine code VC, VV and VM. A week after second vaccination the egg were collected and analyzed the antibody titer against H5N1 AIV by heamagglutination test using H5N1 AIV field isolates as standard virus (Nagrak (2009) and Lawang (2010)). Egg yolk which contains high antibody titer (above 26) were collected and tested against H5N1 AIV field isolates (Nagrak (2009) and Lawang (2010)) by serum neutralization test. The result showed that H5N1 AIV Nagrak (2009) isolate were neutralized by antibody anti H5N1 AIV from egg yolk produced by hens vaccinated with VS,VC,VV and VM, but Lawang (2010) isolate were only neutralized by antibody anti H5N1 AIV from egg yolk produced by hens vaccinated with VS, VC and VM. It is concluded that hens which were vaccinated with H5N1 AI inactive vaccine were able to protect their off spring against H5N1 AIV from the field by transferred maternal antibody trough the egg yolk with titer above 26 Keywords : Maternal Antibody, Antigen, Vaccine, Egg yolk. .

Judul: Penyelesaian Stacker Crane Problem dengan Algoritme Largearcs dan Smallarcs
Abstrak: In graph theory, the Rural Postman Problem (RPP) aims to determine the shortest route with minimum cost, in which only certain edges or arcs are necessarily traversed. One type of RPP is Stacker Crane Problem (SCP) which deals with a mixed graph but only arcs are necessarily traversed. SCP can be solved by using two heuristic algorithms, i.e. Largearcs and Smallarcs algorithms, which include other algorithms in their steps, such as: Dijkstra algorithm to determine shortest route, Hungaria method to determine minimum bipartite matching, Prim algorithm to determine minimum spanning tree, and van Aardenne-Ehrenfest & de-Bruijn algorithm and Fleury algorithm to determine Euler circuits. The shortest Euler circuit resulted from two heuristic algorithms can be used to find a solution of SCP. The application of SCP is illustrated in establishing the minimum distance route of catering delivery.
