INTRODUCTION Electronic Commerce (E-Commerce) is the process of buying, selling or exchanging products, services and information via computer networks. E-Commerce is part of E-Business, where the scope of E-Business is broader, not only for commerce but also includes collaboration with business partners, customer service, job vacancies and others. In addition to www network technology, E-Commerce also requires database or database technology, electronic mail (e-mail), and other forms of non-computer technology such as goods delivery systems, and payment instruments for E-Commerce (Irmawati , 2011). Online shop selection decisions are made by consumers who use online shop services. The electree method is used to compare online that can meet the required criteria. Choosing the right online shop requires a system in the business field. The system is expected to be used to obtain information and make decisions based on criteria in the online shop effectively. These problems can be classified into problems that are multiobjectivies (there are many objectives) and multicriteria (there are many criteria). To help solve the problem, a Decision Support System was created using the ELECTRE (Elimination Et Choix Traduisant la Reality) method. According to Ranius (2015), decision-making systems are a branch of science that is located between information systems and intelligent systems. The decision making process from the various alternatives that exist requires a criterion. Each criterion must be able to answer one important question about how well an alternative can solve a problem at hand.

RESEARCH METHODE This research is a quantitative study, data obtained using an online questionnaire with a random sample of OnlineShop in Indonesia. The results of the data are processed using the ELECTREE method, which is a method used in assessing and ranking based on strengths and weaknesses through pairwise comparisons on the same criteria. Data analysis is the activity of grouping data based on variables after data from all respondents or data sources are collected. In this study, the steps taken to analyze data are as follows: a.Determine the matching rating of each alternative on each criterion, rated with one to five. By determining the value, which is: 1 = Very Bad, 2 = Poor, 3 = Enough, 4 = Good, 5 = Very Good, b. Determining the value of criteria (weighting preferences) can be determined by judging by one to five. 1 = Very Low, 2 = Low, 3 = Enough, 4 = High, 5 = Very High 3. RESULT AND ANALYSIS 3.1 System Analysis And Design This study discusses the application of the ELECTREE method in determining online stores in Indonesia. After collecting data by means of online questionnaires or questionnaires at the University of Medan City, then an analysis is carried out on the data obtained.. The problem discussed in this study is how to determine the choice of online shop by using the ELECTREE method. The criteria used in the online shop are the price of goods (C1), completeness of goods (C2), shipping cost (C3), quality of goods (C4) and length of time of delivery (C5). In this study, the alternatives chosen were Tokopedia, Shopee, Lazada, Bukalapak and Blibli. 3.2 System Implementation The weight of the criteria 1 = 5 Criteria weight 2 = 3 Criteria weight 3 = 4 Criteria weight 4 = 5 The weight of the criteria 5 = 3 So that W = (5,3,4,5,3) Determination of the range of criteria: Table 3.1 Rating on Criteria Criteria Skor Skor Skor Skor Skor Price Very expensive Expensive moderate cheap Very Cheap  5 4 3 2 1 Completeness  Full Complete Good Less complete Incomplete  5 4 3 2 1 Shipping cost Cheap Enough Cheap Expensive Enough Expensice Very Expensive  5 4 3 2 1 Quality Not Good Poorly Passably Good Very Good  1 2 3 4 5 delivery time Not Delayed Delayed On Time Fast Very Fast  1 2 3 4 5 Based on table 3.1 regarding the determination of the range of criteria, so the matching ratting table of each alternative to each criterion becomes:  Table 3.2 Ratting the suitability of each alternative to the criteria  Alternative Criteria Distance (C1) Time (C2) Cost (C3) Security (C4) Culinary (C5) Tokopedia(A1) 2 4 2 4 3 Shoope (A2) 5 4 2 3 4 Lazada (A3) 4 3 3 4 3 Bukalapak (A4) Blibli (A5) 3 5 4 4 2 3 4 4 3 3  E-ISSN : 2580-5754; P-ISSN : 2580-569X  Zero: Jurnal Sains, Matematika dan Terapan 56 The table above shows the suitability rating of each alternative on each criterion. Since each value assigned to each alternative in each criterion is a suitability value where the greatest value is the best, all the criteria given are assumed to be part of the profit criteria. Decision making gives preference weight as:  𝑊 = (5,3,4,5,3) The decision matrix formed from the suitability table is as follows: 2 4 2 4 35 4 2 3 44 3 3 4 33 4 2 4 35 4 3 4 3x         =  To solve the above problem with the Electre method, it will be done according to the steps previously described. 1.Calculate the normalized decision matrix Normalization is done to eliminate duplication of data, to reduce complexity and to facilitate the modification of data, so that data can be described in tabular form and analyzed based on certain requirements.

Eliminate alternatives that are less favorable:  The matrix provides a sequence of choices for each alternative, that is, if the alternative is a better alternative than the alternative. So that the rows in the matrix E that have the least numbers can be eliminated. In the matrix E, the first row has the number 1, while the other rows have no value. So based on the results of calculations that have been done using the ELECTREE method, the selection of online stores in the alternative is Tokopedia 3. CONCLUSIOON  Nowadays, many companies producing goods, both small and large, use Online Shop as a medium for marketing goods to consumers. There are various kinds of online Shop that we often encounter in Indonesia. The decision support system in selecting Online Shop using the electre method provides consideration for choosing superior online shop based on the criteria set for the alternatives to be selected. The results of calculations using the Electree method can be used as a recommendation that E-Commerce consumers can use to choose the best Online Shop option. Based on the results of the analysis, by taking 5 alternatives as sample data, the best Online Shop recommendation is Tokopedia.  REFERENCES [1] Aprilia, Rima, Triase, T., & Sriani, S.
