Abstract

The purpose of this study is to apply the WebQual 4.0 technique to assess user satisfaction with the academic PortalSIA UINSU website. In addition to a measurement for overall user satisfaction, the study concentrates on the three main components of the framework: usability, information quality, and service interaction quality. 24 enrolled students in the Information Systems study program were given a survey as part of a quantitative descriptive approach. The results indicate that while overall User Satisfaction scored 3.71 (Good), the scores for the underlying quality dimensions were mixed. Usability received a score of 3.51 (Good), and Information Quality scored 3.36 (Fair). The lowest score was for Service Interaction Quality at 2.92 (Fair), identifying it as the primary area of concern. Key issues contributing to this include slow system speed, delays in academic data updates (such as grades and GPA), and the absence of a direct feedback mechanism. The study concludes that the PortalSIA website is generally accepted but requires significant improvements in technical responsiveness and user communication channels to enhance the user experience fully. The findings demonstrate the effectiveness of the WebQual 4.0 model in providing a structured and objective assessment for evaluating web-based academic systems.

Abstract

The business process of selling and procuring products at PT. XYZ still relies on manual coordination and systems that have not yet been integrated, so workflows and process traceability are not yet optimal. This research aims to analyze and model these business processes using Business Process Model and Notation (BPMN). The research method used is descriptive research through observation and document study. The research data is in the form of activity flows, the role of actors, operational documents, and information on the use of the system in the sales and product procurement process. The results show that as-is business process modeling identifies flow inefficiencies, while to-be modeling results in more structured processes, integrated with information systems, and clarifies the roles and responsibilities of actors.
