Abstract

Pusat Teknologi Informasi dan Pangkalan Data (Pustipanda) UIN Jakarta is an institution in charge of managing all information systems and data management for UIN Jakarta. However, security issues are still one of the problems faced by Pustipanda today, such as data leaks, and websites that are often problematic. This research aims to assess the level of information security at the UIN Jakarta Pustipanda data centre using the COBIT 5 framework. Information security is very important in supporting organizational operations, especially facing cyber threats in the data centre environment. The research approach included document analysis, observation, and interviews with stakeholders at Pustipanda UIN Jakarta. Identification of information security weaknesses, assessment of compliance with security standards, and design of appropriate solutions are the subject of the research. It is hoped that the results will provide a comprehensive picture of information security in the data centre as well as concrete recommendations for improvement. The results of the research include an understanding of the status of information security at Pustipanda UIN Jakarta, as well as guidelines for improving information security in accordance with COBIT 5 principles. These efforts aim to reduce risk and protect the integrity, confidentiality, and availability of data in the data centre environment

Abstract

Background: Mobile-based Academic Information Systems (AIS) have become essential for improving accessibility and efficiency in higher education. UIN Jakarta’s AIS Mobile aims to support academic activities; however, user loyalty remains low, as many students prefer accessing services via the web platform. Objective: This study evaluates AIS Mobile services and identifies key factors influencing user loyalty using an extended Expectation Confirmation Model (ECM). Methods: A quantitative approach was employed, involving 334 respondents selected through purposive sampling. Data were collected via an online questionnaire and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) with SmartPLS 4.0.9.3. The proposed model integrates ECM constructs—confirmation, perceived usefulness, satisfaction, and continuance intention—with additional variables: system quality, information quality, trust, habit, and loyalty. Results: Findings indicate that eight hypotheses were supported, confirming significant relationships among confirmation, perceived usefulness, trust, habit, and continuance intention in shaping loyalty. Satisfaction, however, showed no significant effect on continuance intention. The model demonstrates strong explanatory power, with R² values of 0.737 for continuance intention and 0.726 for satisfaction. Habit exhibited the largest effect size, emphasizing its role in sustaining usage. Implications: To enhance user loyalty, developers should prioritize improving system reliability, security, and usability while fostering habitual engagement through intuitive design and personalized features. These insights provide actionable strategies for strengthening AIS Mobile adoption in Islamic higher education contexts.
