Judul: Penerapan Algoritme Dijkstra Pada Rute Angkot Bogor Berbasis Android
Abstrak: There are some problems dealing with angkot in Bogor. The problems are related to the complexity of route system and amount of angkot unit. In this research, information system was developed for guiding user in order to choose the most efficient route to reach the purpose location. The Dijkstra algorithme was employed to support the system in order to find the route that provide the shortest distance from the origin to the purpose location. The system was developed by using Java and XML programming language and evaluated by applying black box testing method. The evaluation results show that the system can succesfully meet all requirements, particularly providing the most efficient route of a certain location.

Judul: Sistem Informasi Angkutan Kota di Kabupaten dan Kota Bogor dengan Google Maps
Abstrak: Many people who live in Bogor use city transport as transportation. Bogor city have many city transport routes, so we need an information system that is capable of providing information on public transportation to the public. The purpose of this research is to develop an information system that can provide information regarding the transport routes that the user needs to take in order to reach a certain destination from a starting position using the shortest possible path. This system is provided in two modes: web-based system and Android mobile system. In achieving this goal, the system uses Dijkstra's shortest path algorithm to provide the route information. From the test conducted , the information system has been able to work well and produce correct output.

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.
