APPLICATION OF TOPSIS METHOD FOR DETERMINATION OF ENGLISH COURSE INSTITUTION

: English course institutions are one of the most sought after non-formal education places to learn and improve English language skills, especially to be able to master the TOEFL well. To choose a suitable course institution, that is by visiting the respective course places. Of course, things like this take a lot of time, effort, and money. For this reason, a decision support system is needed that can provide recommendations for the best course institutions using the TOPSIS method. The data used are 18 alternatives with criteria including course fees, number of facilities, length of study hours, instructor's TOEFL, and distance from the course. The calculation results provide a recommendation that the alternative A Class IBT is the best English course institution. tenaga, dan biaya yang diperlukan. Untuk itu diperlukan suatu sistem pendukung keputusan yang dapat memberikan rekomendasi lembaga kursus yang terbaik menggunakan metode TOPSIS. Data yang digunakan adalah 18 alternatif dengan kriteria antara lain uang kursus, jumlah fasilitas, lama jam belajar, TOEFL instruktur, dan jarak tempat kursus. Hasil perhitungan memberikan rekomendasi bahwa alternatif A Class IBT merupakan lembaga kursus bahasa Inggris yang terbaik.


INTRODUCTION
English is used as an introduction in communicating between nations. With the implementation of English as an international language, people will tend to want to learn English so that they do not lose in international competition. Many people try to learn and master in their own way. Thus, English course institu-tions are an option for places to study and improve English language skills.
In the city of Pekanbaru, there are several English language courses that provide TOEFL, IELTS and TOEIC programs. To choose the appropriate course institutions, that is by visiting the respective course places. Of course, this kind of thing takes a lot of time, effort, and money. For this reason, a decision support Vol. VIII No 3, Agustus 2022, hlm. 321 -328 ISSN 2550-0201 (Online) DOI: https://doi.org/10.33330/jurteksi.v8i3.1599 Available online at http://jurnal.stmikroyal.ac.id/index.php/jurteksi 322 system is needed that is useful in determining the best course institution.
Decision support system (DSS) is a tool that can help make decisions based on certain parameters or to assess certain objects so that ranking can be done to get the best object [1].
Previous studies using the TOP-SIS method, namely, DSS for prospective teachers [2], DSS for the best employee [3], and DSS for elective courses [4].
While the research that applies the TOPSIS method, among others, is the selection of flat screen TV's [5], the study program selection [6], to determine book publisher [7], to landfills [8], and social media selection [9]. Furthermore, another DSS researchs are to provide loans [10], service quality with SMART [11], to determining the selection of majors with the PROMETHEE method [12], and to determining the plot of the tomb with SAW [13].
The purpose of the research is to build a system as a recommendation for a TOEFL English course institution that will be selected using the TOP-SIS method.

Data Collection Technique
The data were obtained through interviews at the TOEFL venue in Pekanbaru City, so that the data obtained were as in table 1, table 2, and table 3  Biaya 1

Method of TOPSIS
The TOPSIS method is a method in which the chosen alternative not only has the shortest distance from a positive solution, but also has the longest distance from a negative solution [14]. The calculation of TOPSIS method ( [15], [16], [17]) : 1) Develop a normalized decision matrix :
3) Solution matrix : where and are : If the criteria is benefit, then: = max and min . and if critreria is cost, then: = min and = max .

4) Calculating distance
 Solution is positive : where : preference value 6) The rangking, the largest value of is the best alternative of .

Calculating TOPSIS Method
The calculation using the TOPSIS method is: 1) Develop a normalized matrix r. From

4) Calculating distance
 Solution of positive Using matrix y, and eq. (7) Table 7 can recommend that the best English course institution is A Class IBT.
