Abstract

Innovation and technological progress have significantly impacted various sectors, notably Indonesia's financial and banking industry. This sector has seen remarkable growth, particularly with the rise of digitalization. A prominent development in this context is financial technology, or fintech, which has emerged to address needs and issues not sufficiently met by traditional banking services in Indonesia. Among fintech innovations, Transfer and Payment technologies have become increasingly popular. Despite these technologies' benefits, they are frequently criticized for various usage-related issues. This study uses the Modified E-Servqual and Importance Performance Analysis (IPA) methods to evaluate the service quality of Transfer and Payment applications in Indonesia. It aims to assess user perceptions and expectations, identify areas for improvement, and determine which service dimensions require enhancement. The research involved 400 respondents who used Transfer and Payment applications. To ensure reliability, the Kuder-Richardson (KR-21) formula is applied to the measurement tool, while descriptive analysis and IPA are utilized to evaluate and map service quality. Findings reveal that user perceptions of the Transfer and Payment applications are rated as ‘good,’ with an average score of 4.01 out of 5.00 (80%). User expectations are slightly lower, at 3.93 out of 5.00 (79%), but still categorized as ‘good.’ However, several attributes fall short of user expectations, particularly in Reliability, Personal Needs, User Friendliness, and Responsiveness.

Abstract

This research compares the service quality of travel agent applications, which are KAI Access and Traveloka, in booking train tickets using the E-Service Quality and Importance Performance Analysis (IPA) methods. This service quality is measured based on seven dimensions of E-Service Quality, including efficiency, fulfillment, reliability, privacy, responsiveness, compensation, and contact. Data were collected through questionnaires from 340 respondents who use the KAI Access and Traveloka applications to book train tickets. The collected data were then analyzed descriptively using the Importance Performance Analysis (IPA) technique to identify priority attributes for improvement based on user satisfaction and importance levels. Based on the Gap Analysis and evaluation of 340 respondents, both the KAI Access and Traveloka apps require improvements as they still need to meet user expectations. The service quality of KAI Access and Traveloka shows significant differences across various dimensions measured by the E-Servqual and Importance Performance Analysis (IPA) methods. The research results are expected to provide recommendations for both applications to improve service quality and user satisfaction. The comparison of service quality is also expected to provide insights into the strengths and weaknesses of each application in providing train ticket booking services.
