Abstract

The Covid19 pandemic which has been taking place since the beginning of 2020 has paralyzed part of the people's economic life. As a result, many countries have implemented massive social restrictions. One of the solutions provided by the government is by administering vaccines to the Indonesian people. This vaccine is expected to be one of the solutions to prevent the transmission of the Covid19 virus and prevent the risk of spreading Covid19. This research aims to conduct further study of vaccine recipients based on the urgency according to the priority scale by considering the aspects that have been determined by the COVID-19 handling task force. This research uses the TOPSIS method. TOPSIS is a multi-criteria decision-making method based on the concept that the best alternative not only has the shortest distance from the positive ideal solution but also the longest distance from the negative ideal solution.

Furthermore, the values of the two vulnerable communities in social, economic and social aspects and finally public officers (C3).

Online shopping transactions are common in today's society. Many people have changed their conventional shopping methods to online modes, so research needs to be conducted to find out what supports consumer decisions in making online shopping transactions through the market place platform. The research method uses TOPSIS, a multi-criteria method that offers an easier and more effective way to find out how or what underlies someone in determining certain decisions. TOPSIS is used to determine the preference value and distance of positive and negative ideal solutions as offered in the study.
