Judul: Kemampuan Netralisasi Antibodi Spesifik Avian Influenza H5 Terhadap Beberapa Virus H5N1 Isolat Lapang
Abstrak: Avian Influenza (AI) is well known as Avian flu, Fowl pest, Fowl plaque, or Flu burung, caused by influenza virus type A. This virus is belonged to Orthomyxoviridae and could infect many kind of species such as bird, pig, horse, cat, as well as human. Vaccination is applied to control the disease using inactivated vaccine, which induced the specific antibody against H5 antigen. Passive immunization using specific antisera against H5 antigen is thought to be usefull in controlling the disease especially in the treatment of infected host. In this experiment the neutralization ability of specific antisera against H5 were studied using various field viral isolates subtype H5N1. Antisera was developed in Cavia porcellus which vaccinated with AI subtype H5N1 in activated vaccine. The titre of antisera obtained is 28 used HI test. Four AI virus subtype H5N1 isolates from 2003 to 2006 agains viral were we as tested virus. The neutralization test showed that the sera were able to neutralizing 10 4 EID50 AI virus H5N1 with neutralization index range between 1,1– 1,3. The result indicated that the specific antisera had the neutralization potency to the field virus.

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: Pemodelan Proses Layanan Bisnis Untuk Routing Dan Costing Transportasi Laut Minyak Sawit: Studi Kasus Di PT. X.
Abstrak: One of business service of maritime transport is to provide ship rental for the tenants to deliver their products to the destination. Main focuses of problem this work are determining routing and costing and time efficient so it can arrives on time. The company needs to determine the route, operating costs are required, the distance to be taken and the optimization time. The purpose of this study was to get the optimal path, determine the operating costs per voyage the ship and determine the rent. The Modeling shows the determination of the route the ship can be done using the Kruskal’s algorithm while the modeling for the cost of rent shows that the magnitude of the rent is affected by the size of cargo ships and operating costs are calculated after the ship sailed.
