Judul: Prototipe data warehouse penjualan produk bakosurtanal
Abstrak: Speeding up reporting process and obtaining strategic information based on a multidimensional analysis query can be done by building OLAP applications integrated with data warehouse. Development of data warehouse Bakosurtanal product sales data and web-based OLAP applications has been done using Palo. Palo is one of the OLAP server with multidimensional data storage model (MOLAP). Mondrian is an OLAP server with relational data storage model (ROLAP) This research aims to develop a data warehouse and wab-based OLAP using Mondrian 3.1.6. This research designs the data warehouse using star scheme and OLAP development. This research produces a web-based OLAP cube consisting of one data cube: sales of products and four dimensions: time, type of data, qualification, and scale. Users can interact with the following facilities: 1) Selecting dimensions to display the information at the level needed, 2) Displaying information in the form of bar charts, stacked bar, line charts, line charts, stacked area, and pie charts 3) Exporting files into Microsoft Excel format. Users can explore this application using OLAP operations including roll-up, drill-down, slice, dice, 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.
