Judul: Modul Extract, Transform, Load (ETL) untuk Data Warehouse Akademik Departemen Ilmu Komputer IPB Menggunakan Kettle
Abstrak: Extraction, transformation, and loading (ETL) are processes which have important role to determine data warehouse quality. ETL is bridging between data source and data warehouse. Activities such as cleaning, integration, and data loading at data were done in this process. Making ETL manually is inefficient, because data that will grow and data with different sources become problematic in data integration. This research performs ETL using special tools that are expected to simplified the ETL process and consistently of data output. ETL tool which used are Kettle, while designing a data warehouse using Pentaho Schema Workbench and result are visualized in OLAP in Mondrian to test the ETL process. The result in this research is a data warehouse having integrated and dynamic ETL.

Judul: Modul Extract, Transform, dan Load untuk Data Warehouse Pengamatan Cuaca Menggunakan Kettle.
Abstrak: Data warehouse merupakan teknologi yang dinilai dapat menangani permasalahan penumpukan data yang berukuran besar. Tahapan penting dalam pembangunan data warehouse adalah proses extract, transform, dan loading (ETL). ETL merupakan penghubung antara sumber data dengan data warehouse. Proses ETL secara manual dinilai tidak efektif dan efisien karena data yang cukup besar dan tersebar di berbagai sumber. Pada penelitian ini dilakukan perancangan dan implementasi modul ETL untuk data warehouse pengamatan cuaca yang dibuat dengan menggunakan perangkat lunak Kettle. Data yang digunakan penelitian ini adalah data pengamatan cuaca dari tahun 1986 hingga tahun 2016 yang diperoleh dari 170 stasiun cuaca di Indonesia, data lokasi stasiun cuaca dan data peta wilayah administratif Indonesia. Pengujian dilakukan dengan melakukan verifikasi dan validasi terhadap modul ETL yang dibangun. Penerapan modul ETL diharapkan dapat meningkatkan efisiensi sumber daya dan menekan biaya dalam implementasi data warehouse.

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.
