Judul: PengembanganData Warehouse dan OLAP untuk Metadata Penelitian Institut Pertanian Bogor
Abstrak: Data warehouse is a subject oriented, integrated, time variant, and nonvolatile collection of data used in strategic decision making. Bogor Agricultural University library has metadata. The activity of searching and browsing in the library Bogor Agricultural University can be based on metadata fields, such as title, author, faculty, department, subject, year, and keyword. This research develops a data warehouse and web-based OLAP (Online Analytical Processing) for undergraduate theses, master theses, disertations, and journal articles. Data warehouse and OLAP are part of Business Intelligence. Document corpus contains 65026 research metadata, 51389 undergraduate theses, 11260 master theses, 2377disertations, and 2000 journal articles from 1958 to 2011. The metadata are represented in a multidimensional model using galaxy scheme that consists of four data cube, with five dimension tables, i.e., faculty, department, time, lecturer, subject, and number of research. The result provides information that can be visualized into various types of graphic models, such as bar graphs, line graphs, and pie charts using Microsoft Sharepoint 2010. This application can be used to analyze undergraduate and graduate research as well as to provide a decision making support for research management in Bogor Agricultural University.

Judul: Pembangunan Data Warehouse Akademik (Studi Kasus : Kurikulum Mayor-minor Program Sarjana Departemen Ilmu Komputer IPB)
Abstrak: University need in-depth knowledge to conduct evaluation, planning and decision making. Static reporting systems are considered not flexible in exploring information within an existing information system. Dynamic reporting tools are needed so that users can perform data analysis by looking at the available data from various dimensions. A solution proposed in this paper is to develop a data warehouse. Information for the data warehouse is extracted from the existing operational data stores. The research represented here elaborates the use of data warehouse for academic purpose at Bogor Agricultural University especially for Computer Science Department, starting from the planning stage to design and implementation stage. Online Analytical Processing (OLAP) integrated with data warehouse is developed to analyze academic data including student‟s grades, GPA, and cumulative GPA for every semester as well as every academic year. This research aims to develop a data warehouse and web-based OLAP using Mondrian 3.1.6 as OLAP server. The steps in this research are 1) data preprocessing including data cleaning, data integration, data transformation and 2) data warehouse using galaxy scheme and OLAP development. This research produces a data warehouse and web-based OLAP containing three data cubes: Subject_Grade, GPA, and Minor. Data warehouse consists of seven dimensions (Time, Generation, Sex, Subject, Grade, Status of study, and Minor) and three tables (Subject_Grade, GPA, and Minor). This application provides information as of bar chart, line chart, pie chart, report with Excel Spreadsheet, and file pdf. Users can explore this application to get academic related information in Computer Science Department by application OLAP operations including roll-up, drill-down, dice, slice, drill through, pivot, etc.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
