Judul: Modul Word Graph Kata Benda pada KG_EDITOR Berbasis Java Desktop
Abstrak: One natural language processing method that can represent result of semantic analysis of a text as a graph is Knowledge Graph (KG). BogorDelftConstruct is a software developed to analyze a text and visualize it as a graph using KG. BogorDelftConstruct was developed using MATLAB programming language, which is not freely accessible. Because of that, in this reseach we develop a system using Java programming language, so everyone can run this system freely. The objective of this research is to add a word graph module for Indonesian noun in the system. Indonesian nouns comprise of 20 word graph patterns. All but one of them are formed by affixation. The process of forming word graph is started by getting root word and affix contained in input word using stemming based on Kamus Besar Bahasa Indonesia (KBBI). The root word is used to determine the part-of-speech in KBBI, which is used as a parameter to determine which pattern is appropriate. The pattern containing the meaning of the word would then be generated by the system. In this word graph module, only 19 patterns can be implemented. From 176 words used in testing, there were only 4 errors, equivalent to an accuracy of more than 97%

Judul: Modul Word Graph Kata Kerja pada KG_EDITOR Berbasis Desktop
Abstrak: Knowledge Graph (KG) represents result of text-semantic analysis as a graph. KG_EDITOR is an application to generate KG. It is a desktop-based application developed using Java programming language. The purpose of this research is to create a module to generate a word graph of Indonesian verb using KG method based on user‟s input. Based on the recent research, there are ten types of word graph for Indonesian verb along with 31 formation patterns due to affixation process. KG generation process is started by input pre-processing. Afterwards the input is looked up in Kamus Besar Bahasa Indonesia (KBBI). The word will be stemmed, if it is not found in KBBI. Then, data will be generated in the form of basic word and affix. Those data are used to determine the word graph pattern to generate. In this research, the module can recognize 10 types of word graph of verb with more than 98% accuracy

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.
