Judul: Studi Reseptor Virus Infectious Bursal Disease (Ibd) Pada Organ Limfoid Ayam Pasca Vaksinasi Dengan Metode Imunohistokimia
Abstrak: Kejadian infektious bursal disease (IBD) berdampak ekonomis bagi peternak karena dapat merusak organ limfoid terutama bursa Fabricius dan menyebabkan kegagalan program vaksinasi. Reseptor VIRUS IBD pada organ limfoid diduga berkontribusi terhadap kejadian subklinis dan klinis IBD pada ayam. Tujuan penelitian ini adalah untuk mengetahui sebaran reseptor virus IBD pada organ limfoid ayam yang mendapat vaksin IBD yang berbeda. Sebaran reseptor pada bursa Fabricius, limpa, dan timus diamati secara mikroskopis menggunakan metode imunohistokimia dan dievaluasi menggunakan perangkat lunak Image J®. Penelitian ini menggunakan antibodi monoklonal anti sel LSCC-BK3 (Gifu University, Japan) sebagai antibodi primer. Hasil penelitian menunjukan bahwa reseptor virus IBD banyak ditemukan pada bursa Fabricius kemudian limpa dan timus. Sebaran reseptor virus IBD pada organ limpa dan timus ayam yang mendapat program vaksinasi 1 kali tidak berbeda nyata dengan ayam yang mendapat program vaksinasi IBD 2 kali. Sebaran reseptor virus IBD pada organ bursa Fabricius ayam yang mendapat program vaksinasi 2 kali lebih banyak dibanding ayam yang mendapat program vaksinasi IBD 1 kali.

Judul: Kajian vaksinasi Infectious Bursal Disease (IBD) dengan uji serologi dan Imunohistokimia pada broiler
Abstrak: In Indonesia,Infectious Bursal Disease (IBD)has been an important poultry disease because of its immunosuppressive and mortality impacts.To prevent the disease, avariety ofvaccines containing different IBD virus strainsare currently available in the market. This study was aimed to compare IBD vaccination strategies using 3 different vaccines in broiler chicken followed by challenge using Indonesian field virus (Kediri strain from East Java, Indonesia). There were 8 broiler groups, group I as infection control (did not vaccine, but infected), and group NI as vaccine negative control (did not infected, and did not vaccine). Vaccine used in this study are vaccine strain W2512 (intermediate plus vaccine) which applied at hatchery, vaccine strain D78 (intermediate vaccine) which applied at 13 days and vaccine strain 228E (intermediate plus vaccine) which applied at 13 days. Evaluation antibody titer by using Enzyme Linked Immunosorbent Assay/ELISA method at 21 and 29 days, demonstrated that there were no significantly difference among all groups. Applied of vaccination made decreased in bursal index while infection of IBD will increasing in bursal index. Immunohistochemistry works showed that there were positive immunoreactivities results by using field virus primary antibody in both vaccinated groups and infected groups

Judul: Implementasi Space Time Composite (STC) Data Model Menggunakan Model Data Relasional
Abstrak: The data model is a concept that describes the data stored in the database and the relationship between the data to the user in logic. Development of data models is very important in the design of the database as the basis of the stage of database design to be made. This study aims to apply the concept of Space Time Composite (STC) on the Model Data storage vector data types that can store enough information and describes the process of drafting objects and objects spatiotemporal evolution over time. From the results of the test queries on the data model that have been created, queries in a system are acquired that can help display the information preparation of objects from time to time and know the history of the object polygon and arc that has undergone changes in topology.
