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.

Judul: Pembangunan Spatiotemporal Data Model pada Tipe Data Vektor dengan Konsep Event-based Spatiotemporal Data Model (ESTDM)
Abstrak: Spatiotemporal data are spatial data with well-defined spatial, area, and location information, as well as temporal attribute (time). Various types of changes to the spatiotemporal data require a data model to store this information. This research constructed a data model for spatiotemporal data with event-based spatiotemporal data model (ESTDM) concept that can store the cause of spatiotemporal data changes, type of changes, and action of changes conducted by spatial objects. The used data were land surface area in Indonesia in 1994 and 2001 in the form of polygon vector data. The data were processed by the ESTDM concept in order to produce an appropriate data model that can provide the necessary information with spatiotemporal query analysis. There were eight spatiotemporal queries that were used to analyze the object changes, in the form of contain, overlap, and coveredby. It was found that the application of event-based spatiotemporal data model concept on the polygon data type requires a more diverse type of data in terms of spatial changes and longer observation time. Other spatiotemporal queries may be used to improve the proposed data model.

Judul: Perubahan patologi ginjal ayam akibat penyakit virus infectious brochitis
Abstrak: Infectious Bronchitis (IB) adalah penyakit viral akut dan kontagiosa yang disebabkan oleh virus golongan Co- ronaviridae. Virus ini menyerang alat pernafasan ayam dan beberapa strain seperti Australian T, A3, S, Holte menye rang ginjal ayam dan mengakibatkan tingkat mortalitas yang tinggi terutama pada anak ayam umur lebih kecil 5 minggu. Kerugian lainnya adalah pertumbuhan yang terlambat, produk- si telur merosot dan daya tetas telur yang menurun. Ginjal unggas secara garis besarnya serupa dengan pada mamalia, hanya pada unggas fungsi ginjalnya bekerja lebih efisien. Urin dan feses dikeluarkan bersama-sama melalui kloaka. Sesuai dengan fungsinya yaitu filtrasi, sekresi atau ekskresi dan absorpsi peranan ginjal amat penting dalam menjaga keseimbangan cairan serta zat-zat yang ada dalam tubuh. Kerusakan pada ginjal akan mengakibatkan terganggunya keseimbangan cairan serta zat-zat yang ada dalam tubuh. Kerusakan ginjal yang diakibatkan oleh virus IB adalah berupa Nephritis Interstitialis. Kekebalan silang yang terjadi antar serotipe tidak cukup untuk melindungi tantangan dari virus dialam, oleh sebab itu vaksin yang digunakan disuatu daerah harus sesuai dengan serotipe virus IB didaerah bersangkutan.
