Penerapan AHP-TOPSIS pada Sistem Pemeringkatan Jurnal Informatika Berbasis Konsensus Stakeholder

Abstract

Selecting a scientific journal for publication is a crucial step for researchers; however, the vast array of available journals often leads to hesitation due to varying quality standards and costs. This study aims to develop an objective decision support system for ranking informatics journals by integrating the Analytic Hierarchy Process and the Technique for Order Preference by Similarity to Ideal Solution methods. This integration is based on a collective consensus regarding criteria weights gathered from 76 expert respondents representing journal users (9 lecturers, 63 students with publication experience, and 4 researchers from the National Research and Innovation Agency/BRIN). The AHP method is employed to determine the criteria weights through consistency testing, while TOPSIS is used to rank 20 alternative national informatics journals indexed in SINTA. The results indicate that the "Aims & Scope" criterion is the top priority with a weight of 0.500, followed by the Accreditation criterion (0.157). The validity testing of the weights yields a Consistency Ratio (CR) of 0.097, indicating that the evaluation is consistent and valid. In the ranking stage, JOIN (Jurnal Online Informatika) secures the first rank with the highest preference value of 0.884. This system successfully provides measurable recommendations for publication venues while minimizing subjectivity in journal selection.
