Abstract

The more e-commerce that develops in Indonesia, the more competitiveness on each platform increases. Users also definitely have their own preferences in choosing their favorite e-commerce. Critical Success Factors are something that must be known and considered because they determine the success or failure of a company. By using the weighted product method, the authors conducted a study to find out what criteria determine the preference of an e-commerce compared to other e-commerce among the students of the Sepuluh Nopember Institute of Technology, Surabaya. There were 49 students involved in this study, namely a total of 27 women and 22 men with an age range of 18-22 years. The process of collecting data from respondents is carried out by means of a survey which will then be analyzed using decision support methods. The existence of decision support methods, such as weighted products, helps decision making to provide more objective results. This method was chosen because it is calculated and can be understood easily. The weighted product is a method that considers various criteria and also the weight of each criterion that will be assessed by providing a scale on the existing alternatives. The criteria used are 10 which in this study are grouped into four groups, namely efficiency, compliance, system availability, and privacy. The final result of this research is that Tokopedia (A1) is ranked first as the most chosen e-commerce by students with a value of 0.3498. In second place is Shopee (A2) with a value of 0.3369, and Bukalapak (A3) with a value of 0.3133 is in third position. Tokopedia ranks first because it has advantages in several criteria, namely ease of access (C2), has search engine accuracy (C3), suitability of goods received (C7), has a system that works well seen from the average rating given (C8), has speed when making transactions (C9), and has good privacy and transaction data security (C10). From the results of this study, it is hoped that it can provide an overview to related e-commerce companies about their products from the user's point of view.
