Alumnus is someone who has graduated from high school or college and has an important role in showing image and quality, because the alumni association forum is not just a forum for friendship between alumni, but also a forum for discussion and communication in an effort to advance higher education. Until now, alumni of the National University (UNAS) integrate and communicate only through social networks such as WhatsApp and Facebook, so with this web-based internet facility, alumni can utilize and facilitate communication between alumni. This web-based social network is designed not only to connect alumni from the National University (UNAS) but can establish relationships between National University lecturers (UNAS) and can exchange information in various types such as job vacancies, training, professional certification, campus environment activities and information others that are useful for alumni and lecturers of the National University (UNAS). This site was created by first starting the system design using UML then proceed with the creation of a user interface and using the PHP and MySQL programming languages as database management. This site still has some shortcomings both in terms of features and security

Humans are facing a non-natural disaster that threatens the entire human population on Earth. Non-natural disaster is called Corona Virus Desease (COVID-19), which is a large family of viruses that can attack humans and animals that are currently a global pandemic. Humans usually cause respiratory infections, ranging from the common cold to serious illnesses such as MERS and SARS. COVID-19 itself is a new type of coronavirus found in humans and in the Wuhan area, Hubei Province, China in 2019. To assist medical staff in early detecting symptoms experienced by patients and facilitate the administration of hospital records, one of them was made an expert system that could detect this COVID-19 early with the Certainty Factor (CF) method. This expert system mimics similar symptoms experienced by COVID-19 patients and will be grouped into several patient statuses. Patients who experience serious symptoms will be grouped into Patients Under Supervision (PDP) and patients who are considered to have milder symptoms will be grouped into Insider Oversight status (ODP) while those who experience symptoms that are outside of the main symptoms will be classified into Non Suspect (NON) status . From 152 patient data inputted in this study, 114 ODP results with an average CF value of 91.38%, 36 PDP with an average CF value of 98.25% and 2 NONs with an average CF value of 40%. CF with system calculation experiments that represent patients get a CF value of 0.998848 or 99.88% to PDP. This expert system can be used to make decisions that can help medical personnel perform actions and administer better before conducting a through test in the laboratory to ensure positive or negative patients COVID-19
