Abstract

Abstract —  The rapid integration of digital technologies into higher education has positioned e-learning as a fundamental medium for delivering teaching and learning activities. Nevertheless, widespread adoption of e-learning platforms does not necessarily translate into improved learning outcomes. Consequently, assessing the effectiveness of e-learning from an information systems perspective remains an important area of investigation. This study examines the influence of information quality, system quality, service quality, and internet self-efficacy on perceived learning effectiveness by employing the Information Systems Success Model as the underlying theoretical framework. A quantitative research design was adopted, and data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). Responses were collected from 206 university students who actively utilize e-learning platforms in their academic activities. The findings reveal that the proposed model accounts for 73.1% of the variance in perceived learning effectiveness. Among the examined factors, system quality demonstrates the strongest contribution, followed by service quality, information quality, and internet self-efficacy. All hypothesized relationships were found to be statistically significant. The results highlight that the effectiveness of e-learning is shaped not only by the technical performance of the platform but also by the quality of supporting services, the relevance of information provided, and users’ confidence in utilizing internet-based technologies. These findings provide empirical evidence for the applicability of the Information Systems Success Model in the context of higher education and offer practical insights for improving digital learning environments.   Key word — e-learning effectiveness; information systems success model; higher education; learning effectiveness.

Abstract

Digital academic services at Universitas Stikubank (UNISBANK) Semarang still face obstacles regarding the high frequency of service disruptions, necessitating a systematic evaluation of IT governance. This study aims to evaluate the capability levels of the APO07 (Managed Human Resources) and DSS02 (Managed Service Requests and Incidents) domains using COBIT 2019. A quantitative descriptive method was employed using a Process Assessment Model (PAM)-based questionnaire administered to 43 respondents. The determination of capability levels is based on the adaptation of mean scores of respondent perceptions regarding process attributes, representing a questionnaire-based evaluation rather than a formal evidence audit. The results indicate that APO07 and DSS02 achieved Level 3 (Established) with average scores of 3.80 and 3.82, and gaps of 0.20 and 0.18, respectively, towards the Level 4 target. The main weaknesses were identified in workload management (APO07.05) and incident classification (DSS02.01). This study recommends improving data-driven management through quantitative performance measurements such as MTTR and ticket automation to achieve more predictable service stability.

Abstract

Social Network Analysis (SNA) is a crucial quantitative methodology for mapping relationships and identifying connectivity structures within a group. This research specifically explores the use of the NetworkX library in Python as an effective tool for analyzing social networks. The primary objective of this study is to apply the Degree Centrality method to measure the level of connectivity and identify the most popular actors in a social network. The methodology employed is the quantitative analysis of an undirected graph modeled from the us_edgelist.csv dataset, which contains a list of relationships among political figures in an edge list format. Data processing utilized pandas, and the graph object was constructed using NetworkX. Degree Centrality was calculated for each node, with the results being normalized to provide a relative value. This normalization allows for a direct comparison of how active each actor is within the network. The centrality results were then visualized, with node sizes adjusted based on their Degree Centrality score. The results of the analysis indicate that figures like Bush and Obama possess the highest Degree Centrality score, 0.25, suggesting they have the greatest number of direct connections in this network. This high value confirms their role as the most active or central actors in the exchange and interaction within the political network studied. This finding validates the effectiveness of Degree Centrality as an indicator of high involvement. The study concludes that the implementation of Social Network Analysis using NetworkX provides a robust framework for understanding political relationship structures. Therefore, Degree Centrality is a reliable metric for quantifying actor activity and accurately identifying individuals who form the center of connections within the network.
