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: Prototipe Data Warehouse Data Penjualan Produk BAKOSURTANAL
Abstrak: National Coordinating Agency on Surveys and Mapping (BAKOSURTANAL) is a non ministry government agency authorized to conduct governance duty in the field of surveys and mapping. BAKOSURTANAL holds the prime role in the distribution and services of maps to the public. One of BAKOSURTANAL activity is selling maps, atlas, and other products required by its stakeholders. The reports of sales revenue are not only necessary to improve services, but also can be used to know the exact amount of sales revenues in BAKOSURTANAL. The process of analyzing data of sales is still done manually by looking at the existing data of sales. This way of data processing leads to a less accurate result, and also requires significant time and efforts. Building OLAP application integrated with data warehouse is one way to analyze and to have the knowledge of sales revenues with different point of view. This research is intended to make the data analyzing on surveys and mapping’s sales products no longer done manually, so the result can be more accurate. The steps require : covering, pre data processing, designing and developing of data warehouse, continued with developing of OLAP application. Data warehouse is developed using the galaxy scheme. This research yields in forming four dimensions (Time, Data Classification, Qualification, and Scale) and the two facts (sale_sheet and sale_price). The development of data warehouse of BAKOSURTANAL’s sale products produces two data cubes, which are the sale sheet data cube and the sale price data cube. The two data cubes can be visualized quickly and accurately in three forms of graphics and charts using the OLAP Palo 2.5. The operations of OLAP conducted on the data cubes are roll-up, drill-down, dice, and slice.

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.
