Abstract

Along with technological developments, one of the features used by many users is electronic money. QRIS as an electronic payment method is currently widely used by citizens to carry out payment transactions. However, more in-depth research needs to be done to find out the factors that influence the use of QRIS. This research aims to determine the background that underlies users in using the QRIS method. This research method uses the Technology Acceptance Model or TAM. TAM is a method that can be used to find out how technology is accepted by users with valid measurement results. The research results show that the majority of users use the QRIS payment method because of the perception of convenience, thereby generating interest among users

Abstract

In order to improve the quality of learning in tertiary institutions, it is necessary to carry out periodic evaluations so that the quality of education can increase and adapt to needs. Performance appraisal is carried out in order to know the teaching and interpersonal quality of the lecturers so that they are in line with the education quality standards. To determine the best lecturer performance, it needs to be done further in order to get accurate results. This study aims to determine the best lecturer performance by using the TOPSIS method decision support system. TOPSIS is a method that can solve multi-criteria problems so as to get maximum results. The results show that the most ideal criterion in determining outstanding lecturers is the pedagodic aspect. Research can be used in multi-criteria decision-making processes with accurate results.

Abstract

One thing that can be done to prevent cervical cancer in women is to vaccinate against HPV. However, further research needs to be done on the priority scale of vaccine recipients so that the goal of service cancer prevention can be carried out. The aim of the study was to determine the administration of the HPV vaccine to women to prevent cervical cancer. The research method used is the TOPSIS method. TOPSIS uses alternative criteria so as to get ideal results from the various options offered. The results showed a value of 1.22 for criteria C4, a value of 0.83 for criteria C1, a value of 0.53 for criteria C2 and a value of 0.37 for criteria C3. Suggestions for giving vaccines should be carried out according to priorities, namely sexually active women (C4), married women (C1), adolescents (C2) and children (C3).

Abstract

To prevent the spread of the COVID-19 virus, the government has issued a caring and protective application that can be accessed on the user's mobile device. The caring protection application aims to protect and trace contact history and provide notifications if the user is in the red zone, namely an area infected with covid19. This study aims to determine whether the application of care to protect is used and well received by the community by using the Technology Acceptance Model (TAM) method. TAM is an information systems theory that creates a model that is used to analyze how users are willing to accept and use a technology. The results of the study indicate that the interest in using the Care Protect application has a significant effect on the actual use of the application based on research that has been carried out on respondents.

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. The research resulted in data that the community who should be the priority for the next vaccine recipient is the economy actor society (C2). Furthermore, the values of the two vulnerable communities in social, economic and social aspects and finally public officers (C3). The research resulted in data that the people who should be the priority for the next vaccine recipients are the people who are economic actors (C2).

Abstract

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. The results show that free shipping is the main reason for a consumer to make online transactions and fashion products are the most purchased items in online transactions.
