Judul: Konsep Dasar Pembuatan Distribusi ILOS Hasil Turunan Distribusi PCLinuxOS
Abstrak: Saat ini Open Source Software (OSS) berkembang cukup pesat karena kode sumbernya bebas untuk digunakan, dipelajari, dikembangkan dan disebarluaskan. GNU/Linux merupakan salah satu sistem operasi open source. Kebebasan yang diberikan oleh Open Source Software (OSS) tersebut memungkinkan orang atau perusahaan untuk membuat distribusi GNU/Linux sesuai kebutuhan masing-masing. Di Institut Pertanian Bogor (IPB), dengan adanya distribusi GNU/Linux ILOS (IPB Linux Operating System) diharapkan akan menjadi media pemersatu untuk Open Source Software (OSS) yang dibuat atau dikembangkan oleh mahasiswa IPB. Penelitian ini bertujuan memberikan penjelasan mengenai konsep dasar pembuatan distribusi GNU/Linux hasil re-mastering dengan batasannya adalah distribusi yang akan dibuat merupakan hasil re-mastering dari turunan atau keluarga Red Hat serta lingkungan desktop yang digunakan adalah K Desktop Environment (KDE).

Judul: The Development of ILOS Distribution for Education (ILOSedu).
Abstrak: The objective of this research is to develop a Linux distribution, ILOSedu, targeted for academic users. This distribution is built through remastering another established distribution, similar to the previously developed ILOS in 2008. In order to know the needed applications to include in ILOSedu, a survey was conducted at FMIPA IPB, participated by 27 students and 14 lecturers. We experimented with Fedora Core and PCLinuxOS using Revisor and Mklivecd to remaster, respectively. PCLinuxOS with Mklivecd was chosen for the final ILOSedu as it gave better flexibility in the remastering. Comparison results with ILOS show that ILOSedu has better hardware support. Keywords: Linux, ILOSedu, ILOS, remastering.

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.
