Undip, Semarang (06/05/2026) – The Doctoral Program in Information Systems at the Graduate School of Diponegoro University held another dissertation defense on Monday, May 4, 2026, in the Main Courtroom TTB A Floor 1. On that occasion, Dyna Marisa Khairina successfully defended her dissertation and achieved the cum laude distinction with a GPA of 4.00.
The dissertation titled “Model for Measuring the Success of Integrated Information System Architecture Based on Usability Evaluation in the Enterprise Architecture Domain of Auction Service Systems.” This research develops a measurement model to assess the success of integrated information system architecture thru a usability evaluation approach in the Enterprise Architecture (EA) domain, specifically in auction service systems.
The Dean of the Graduate School of Diponegoro University, Prof. Ir. Mochamad Agung Wibowo, stated that Dyna Marisa is an active, diligent, and steadfast student in undergoing the research guidance process, successfully achieving a perfect GPA.
“This shows that the learning process at Undip is going very well.” Alhamdulillah, Dyna also successfully published 6 scientific papers in the span of 3 years, 3 months, and 3 days. “May this achievement serve as an inspiration for Doctoral students in Information Systems to complete their studies promptly,” said the Dean of SPs Undip.
Meanwhile, the Head of the Doctoral Program in Information Systems, Prof. Dr. Ir. R. Rizal Isnanto, S.T., M.M., M.T., IPU., ASEAN Eng., stated that Dyna is the 64th graduate of the Doctoral Program in Information Systems.
“Alhamdulillah, the research conducted was very good and is expected to benefit the community. May this achievement serve as an example for other students to complete their studies on time and achieve the highest accomplishments that are beneficial for the institution and the country,” he said.
In her presentation, Dyna explained that Enterprise Architecture (EA) comprehensively depicts the elements of Information Technology within an organization. EA is viewed as an Information Systems practice because it encompasses both business and technology perspectives, while also serving as a strategic planning document that serves as a reference in the comprehensive development of information systems. The information system architecture itself is part of the Enterprise Architecture layer.

According to him, good planning and development of information system architecture must be able to bridge business needs with the development of systems or software applications, so that alignment and optimal system benefits are achieved.
He added that organizations often face challenges in ensuring that the information systems built are accepted and used effectively. Therefore, a more integrated measurement model is needed to comprehensively evaluate the success of information system architecture implementation.
