Judul: Data warehouse dan aplikasi olap akademik kurikulum mayor-minor berbasis linux
Abstrak: Data warehouse is a specialized database for decision support purposes, which is integrated data from different systems, query performance, relieving source systems from long running queries, and the tracking of history. Accordingly, data warehouse is often use by company. This research represents the elaboration of data warehouse for academic purpose at Bogor Agricultural University using Online Analytical Processing (OLAP). OLAP is part of the broader category of business intelligence, which also encompasses relational reporting and data mining. OLAP which is integrated with data warehouse, developed to analyze academic data yearly including student’s grades, GPA, and cumulative GPA for Major and Minor. This research produces a data warehouse and web-based OLAP containing two data cubes: Subject_Grade and GPA. Data warehouse consists of seven dimensions (Time, Generation, Sex, Subject, Grade, Status of study, and Minor) and two cubes (Subject_Grade and GPA). This application provides information as of report with Excel Spreadsheet, and pdf file. 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: 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: Durability of Specific Immunoglobulin (Ig) Y Againts Influenza and Covid-19 in Sunscreen
Abstrak: The benefit of specific immunoglobulin Y (Ig Y) as an active ingredient in personal care products such as sunscreen has not been properly studied. Our study aims to evaluate the reliability of specific IgY against influenza and the COVID-19 virus in a sample sunscreen product. Specific IgY influenza and COVID-19 viruses were inserted in the sample sunscreen at two concentrations of 0.1% and 0.25%. Three treatments were observed: control (C) sunscreen without IgY, treatment 1 (T1) sunscreen with 0.1% IgY, and treatment 2 (T2) sunscreen with 0.25% IgY. Organoleptic observations were carried out to monitor changes in aroma, color, and texture, and sunscreen sampling was done every week for 6 weeks. The durability of IgY was evaluated using an enzyme-linked immunosorbent assay (ELISA) and a neutralization assay. Organoleptic observation from weeks 1 to 6 showed consistency in its aroma, color, and texture. Enzyme-linked immunosorbent assay and neutralization assay (NA) results of the T1 and T2 groups showed negative results except for sample T1 at week 5, which showed a positive result in the Influenza A ELISA. Based on the results, it seems that IgY concentrations of 0.1% or 0.25% were not optimal. However, this negative result might be due to low concentration of the IgY and the presence of beeswax, which inhibits IgY and causes it to dissolve in distilled water, thus preventing it from being detected in the assay.
