Abstract

M-health plays a crucial role in providing medical services through features like online doctor appointments. While it offers convenience, there are challenges in its adoption among the elderly. The success of M-health depends on user acceptance and continued use. Therefore, an evaluation of information technology focused on the elderly in Indonesia is necessary. Technology accepted by users is not necessarily successful, and vice versa. This study aims to identify factors influencing the acceptance and success of M-health applications among the elderly. It combines the UTAUT and Delone & McLean models to investigate acceptance and success factors. The variables used are performance expectancy, effort expectancy, information quality, system quality, service quality, user satisfaction, and continuance intention. The PLS-SEM method is used to process respondent data. Analysis result shows that 61.6% of elderly users' satisfaction with M-health is influenced by information quality, service quality, performance expectancy, and effort expectancy. Meanwhile, 59.4% of the continuance intention is influenced by user satisfaction. This indicates that the application is well received and successful because it provides a satisfying experience. This study confirms that the combination of the UTAUT and Delone & McLean models is adequate.

Abstract

Education for early childhood, especially for PAUD TK-B in the age range of 4-6 years, is crucial in providing and shaping the foundation of children's knowledge. An engaging teaching method will enhance children's interest in learning, thus the need for digital learning media as an alternative. One step in implementing digital learning is through Educational Games. This research is conducted by developing the PAUD TK-B Nurussunnah Educational Game using the Multimedia Development Life Cycle (MDLC) method. The game's validation includes usability aspects such as effectiveness, satisfaction levels, and adaptation to the TK-B curriculum. After development, the educational game undergoes alpha and beta testing using the black box method. Beta testing involves evaluating usability for the efficiency and satisfaction of TK-B students, with an effectiveness rate of 98.94%  and satisfaction rate of 88.57%. The interview results with expert teachers indicate that the educational game aligns with the curriculum at the educational unit level for PAUD. Thus, based on the research findings, the PAUD TK-B Educational Game application can be considered an alternative learning media for TK-B students.

Abstract

Student satisfaction reflects educational quality, influences retention, and enhances institutional reputation. This study examines the impact of student performance and motivation in online learning using Naïve Bayes and Logistic Regression. Data from 316 respondents at PLN Institute of Technology, collected during the COVID-19 pandemic via Microsoft Teams, were divided into 80% training and 20% testing. The process included questionnaire distribution, data labeling, parameter determination, and normalization to ensure completeness and reliability.  Questionnaire data is stored in Excel format and was processed using Python for programming, Pandas for data manipulation, and Kaggle for dataset management, before being analyzed with Naïve Bayes and Logistic Regression. Finally, the processed data is tested for accuracy using confusion matrix. The results show high precision, recall, f1-score, and accuracy for both methods, with Naïve Bayes achieving an accuracy 93.75% to 97.44% and Logistic Regression achieving 98.95%. In summary, Naïve Bayes can be optimized with threshold adjustments, but Logistic Regression is more reliable than consistent, maintaining high accuracy across different thresholds. Institutions can update their strategies using the latest data to enhance learning experiences. From those results, it can be concluded that Naïve Bayes method should be enhanced, while Logistic Regression is proven reliable. In the future, researchers are encouraged to use more diverse datasets while also considering external factors such as technological infrastructure and psychological support.

Abstract

This article analyzes the satisfaction of website-based virtual tour users using the usability scale system method for tourism experiences in Chinatown Semarang for respondents who use the virtual tour application both in the initial and final applications. This research aims to compare user satisfaction by analyzing the score calculation results from 80 respondents from each virtual tour application using the system usability scale method where the virtual tour in the initial application and the virtual tour in the final application have differences in the addition of a simple interactive website and a guide in the form of a manual book and video tutorial in the final application. The system usability scale d calculation score was obtained with an increase in value of 7.875. This proves that modifying the application and adding a guide feature in the form of a manual book and video tutorial can help respondents use a virtual tour in Semarang's Chinatown village. The advice obtained in this research is that it is hoped that for future research, you can use paid hosting because, in the study here, the virtual tour application still uses free hosting, which still has limitations in processing files, so it takes longer for users to access the virtual tour in Semarang Chinatown Village.

Abstract

One of the companies in Semarang engaged in gadget sales services has an Apple Ecosystem information system for selling products from an exclusive brand, Apple. Inside there are sales transactions and also service devices iPad, Macbook Air, Macbook Pro, AirPods, Mac, and Apple Accsessories. This research uses purchase transaction data from Apple Ecosystem customers for the period 2023. The use of RFM (Recency, Frequency, Monetary) analysis helps in determining the attributes used for customer segmentation. To determine the optimal number of clusters from the RFM dataset, the Elbow method is applied. The dataset generated from RFM is grouped using the K-Means algorithm, the quality of the algorithm will be compared in cluster formation using the Silhouette Coefficient method. All procedures will be loaded into the Customer Segmentation App (RFM Clustering) web application. Customer segmentation from RFM datasets that have been clustered produces 3 optimal clusters, namely Cluster 2 is High Spenders with 326 customers, Cluster 0 is VIP Customers, Cluster 1 is Frequent Buyers. Cluster validation of k-means using the silhouette coefficient produces a value of 0.3524.

Abstract

This study examines disparities in the implementation of Indonesia’s Electronic-Based Government System (SPBE) which remain fragmented across regional governments and hinder efficient service delivery. The purpose of this research is to develop a hybrid enterprise architecture planning framework that combines TOGAF, Zachman, FEAF, and Gartner models to achieve more harmonized and interoperable SPBE adoption. A quantitative explanatory method was used with Partial Least Squares Structural Equation Modeling (PLS-SEM), involving data from 337 valid respondents across nine district and city governments in West Java Province. Four main constructs were examined, including SPBE implementation standardization, operational procedure clarity, technology harmonization, and institutional collaboration. The findings show that all constructs significantly improve digital governance effectiveness, with standardization being the strongest influencing factor with a coefficient value of 0.423 and significance level below 0.01. In addition to statistical validation, the study presents an operational framework containing procedural flow, logic matrix, and pseudocode that bridges theoretical concepts and practical implementation in SPBE planning. This hybrid framework provides a structured but also flexible approach suitable for Indonesia’s decentralized governance by enhancing interoperability, transparency, and coordination between agencies. Overall, the research contributes both theoretically and practically by demonstrating how the integration of enterprise architecture principles can strengthen SPBE implementation and support sustainable digital transformation within local governments.

Abstract

This article explores how college students adopt video conferencing software for distance education. This research aims to examine the factors that influence the spread of video conferencing programs in Indonesia. A video conferencing application is a multimedia program that generates audio and visual content to facilitate real-time, two-way communication between its users. Because of COVID-19, classes of all kinds are now being taken online. As a result, more people are turning to tools like video conferencing. Therefore, learning how to access student video conferencing software is crucial. The UTAUT 2 and Delone & McLean models will be integrated into the analysis. A total of 327 people answered the survey. Next, we used the PLS-SEM technique in smart pls 3.0 to analyze the data collected from the respondents. The R-Square value of 26.2% for the retention intent variable and 62.3% for the user satisfaction variable demonstrate that independent variables in the study can explain endogenous variables and that the remaining variance is influenced by factors external to the survey.
