Coronavirus disease 2019 or COVID-19 caused by SARS CoV 2 is a tragedy in the world of global health. Even the World Health Organization (WHO) has stated that the corona virus outbreak is a Public Health Emergency of International Concern (PHEIC) or an international public health emergency. Not only has an impact on health but this virus outbreak also has a major impact in various sectors such as disruption of the country's economy, obstruction of the teaching and learning process and so on. This impact is caused by the rapid spread of the virus. Therefore, the authors designed a monitoring and screening application for COVID-19 using certainty factor and forward chaining methods which aim to make it easier for people to monitor the spread of the COVID-19 virus in real time and be able to carry out early screening for COVID-19. Both of these methods produce a system diagnosis with the same results, that is, someone is indicated as SUSPECT COVID-19.

Letter is a written communication medium that is made or received by a party related to the implementation of a main task and function of the organization to another party. The Office of the Secretariat of the Rectorate of the National University, which is the working unit for managing correspondence for the leadership, is currently still using manual mail management, both in recording, archiving and disposition. Therefore, the authors designed a mail management system at the secretariat of the web-based rectorate with the PHP programming language and MYSQL database that are easily accessible online via internet browsing, with the aim of making it easier for employees to manage letters, so that work efficiency has increased, disposition becomes faster. and accurate, and the mail management system is becoming more integrated and computerized. The white box testing method is used in system testing, where the results obtained are of the same value for the number of Cyclomatic Complexity City (CC) = 22, Region (R) = 22 and Independent Path = 22, meaning that the logic flow of this system shows that the mail management system is based on This website is correct and appropriate, and free from logical errors.

Nowadays the economy is an important factor in the survival of the society as well as the state. One of the competence needed as a strategy for economic problems in terms of buying and selling goods offered, particularly the selling price of the product. As a support for the Society 5.0 era, this research is conducted to ease the setting of the selling price with economic methods and algorithms. The technique used to set the selling price is Cost Plus Pricing. In the application of the method, this system will generate the product selling price collaborated with the Forward Chaining algorithm to provide recommendations on the profit margin determined based on several facts that have been processed from a set of kaggle data. These recommendations can support or compare the value of the margin that a user wants. The test is carried out with the Stress Testing system using the Apache Jmeter tools resulting in an error value of 1%, std.deviation and a good increase in throught so that the server performance of the selling price determination application can still survive well.
