Sampar, also known as a pest or black death or plague, is a bacterial infection of Yersinia pestis (Y.pestis), where the disease is actually a zoonotic disease, which is an animal disease transmitted by humans. This disease is caused by the bacterium yersinia pestis which lives on fleas, where these fleas live in rodents (especially mice). Fleas spread disease when sucking rat or human blood. This disease is also called plague due to black patches found in the skin of the patient at the beginning of the outbreak. This pestilence was once an epidemic in 1347-1351 in Europe and other regions and killed approximately 75 million people in the world. This disease in Indonesia is still under monitoring and is one of the infectious diseases in the outbreak law that must be reported to the health office. According to WHO this disease is one of the deadly infectious diseases after infection and patients can die within 24 hours. So that people are more careful with this disease so that they are not exposed to pestilence. Because many people do not recognize the transmission of Yersinia pestis bacterial infections and do not know the symptoms that arise from pestilence. then a system for pestilence is created which aims to better diagnose early onset of this pestilence. The method applied in expert systems and one of them is a case based hybrid. Hybrid case based is one of the mathematical theories for proof based on belief functions and plausible reasoning, which is used to combine separate pieces of information or evidence to calculate a probability of an event (Arthur P.Dempster and Glen Shafer)

Pharmacists are professional workers who have basic education and skills in the field of pharmacy and are given the authority and responsibility to carry out pharmaceutical work. In the pharmaceutical industry, both those that have been operating and are about to be established, there must be at least 3 (three) Indonesian pharmacists. Decision Support System (SPK) has the aim of providing predictions, providing information and directing information users to be able to make decisions more effectively. Decision Support System (SPK) applications use a flexible, interactive and adaptable CBIS (Computer Based Information System) that was developed to support solutions to specific unstructured management problems. The VIKOR method is used to overcome the problem of complex multi-criteria systems that focus on ranking and selection of alternatives. The first proposed procedure calculates the ideal and negative solutions by considering the criteria and weights of each alternative, and the corresponding utility.

Continuing education to post-graduate level, even doctoral is the dream of all educators, in this case, lecturers. However, the limited cost is one of the obstacles encountered by a lecturer. The existence of scholarships given by institutions to lecturers to continue their education is a dream for a lecturer. But in awarding the scholarship, use the criteria set, so that the awarding of post-graduate scholarships to selected lecturers is correct and free of errors. For this reason, the author intends to conduct research on the selection of post-graduate scholarships by applying the AHP and WASPAS methods. AHP is used to produce weights on each criterion according to the priority of the criteria for awarding a post-graduate scholarship. While the WASPAS method is used to rank the alternatives. It is expected that the results of the study will provide effective results for the institution towards recipients of post-graduate scholarships.

In the era of globalization which is laden with competition, good service quality is a concern for companies that want to continue to exist, especially companies in the service sector such as banks in Indonesia. Institutions with low service quality will be less desirable or even abandoned by customers. Therefore, identification of service quality characteristics is needed in an effort to improve service quality. One of them is the teller who plays the most important role in customer service. Of course the selection of the best tellers must be done as well as possible. Based on these problems, the PSI method used in this study is to determine the teller by considering aspects of the determination that has been determined by the Bank. The aspects of determination which are the basis of determination by the Bank in determining the best teller are attitude, skill and appearance. By using the PSI method it is expected to be able to assist the leadership of the CIMB Niaga Bank in determining the teller process so that it is faster and more effective. Become a reference for research related to the Bank.

The Covid-19 pandemic which has an impact on people's lives and tourism management, which results in a decrease in public interest in traveling due to the Covid-19 pandemic which requires all people to comply with the regulations set by the government such as the regulations set, namely keeping a distance from crowds and reducing mobility. . Which is where this regulation can hinder activities in traveling because it is certain that traveling will experience close distances, crowding and leaving the house, then this is the cause of business actors in the tourism sector experiencing a decrease in income. So this study was made to answer the problem of determining the best tourism actors during the COVID-19 pandemic by counting data from 7 alternatives and 7 criteria where the criteria that have been set include the number of visitors / week, the application of the Covid-19 health protocol, time restrictions on visits, the use of vaccine bets. for staff, facilities and infrastructure, cleanliness and sanctions for the covid group, these criteria are calculated using the Rank Order Centroid (ROC) method, where this method can be used to generate a weight of importance for each of the predetermined criteria and the Operational Competiticness Rating method. Analysis which is included in one of the decision support system methods that can produce precise and accurate final preference values. So in the study that was determined as the best tourism practitioner during the COVID-19 pandemic, alternative A3 was the Sidebuk Debuk Berastagi Baths with a final preference value of 1,497 as the best alternative
