The rise of digital communication platforms based on the internet has heightened the demand for service quality that aligns with user expectations. Discord, a Voice over Internet Protocol and Instant messaging application, is widely embraced by various communities; however, complaints regarding system stability, service responsiveness, and user support continue to arise. This study aims to evaluate user satisfaction with the Discord application using the Electronic Service Quality (E-SERVQUAL) method. Employing a descriptive quantitative approach, data was collected through an online questionnaire from 128 active Discord users in Indonesia, selected via purposive sampling. The research instrument was crafted based on the six dimensions of E-SERVQUAL: Efficiency, Reliability, Fulfillment, Privacy, Responsiveness, and Contact, comparing users’ expectations with their perceptions. The findings reveal that all dimensions of E-SERVQUAL exhibit negative gap values. The Total Electronic Service Quality score of -0.44 indicates that the overall service quality of Discord falls short of user expectations, with the Responsiveness dimension showing the most significant gap. The study concludes that enhancing service quality, particularly in Responsiveness and user support, is vital for improving user satisfaction.

Digital transformation in education requires media that sustain student engagement in blended settings. This research seeks to design and develop a Moodle-based Learning Management System for Informatics at Vocational High School 1 Koto Baru and to verify its quality and usability for routine classroom use. The study uses a phased development approach (Analyse, Design, Develop, Implement, Evaluate). Participants were 44 tenth-grade learners and 2 instructors; quality was reviewed by 2 subject-matter experts and 3 media experts. Data came from structured questionnaires and were analysed descriptively in %. Findings show content quality is highly valid at 90% overall (89% content indicators, 92% instructional). Media quality is likewise highly valid at 91% (90% ease of use, 93% visual appeal). Classroom applicability is strong, with practicality of 92% for instructors and 92% for learners. Gamification mechanisms (points, levelling up, badges, and leaderboards) provide quick feedback, structured progress tracking, and support for learning orchestration. Overall, the product meets highly valid and practical criteria and is ready for adoption as a modular, trackable Moodle-based course for Informatics at the vocational high school level. Future work includes quasi-experimental tests of learning outcomes, replication across schools and subjects, performance evaluation under high access loads, and development of adaptive learning analytics.

This study aimed to develop and evaluate Augmented Reality (AR)-based learning media for the Earth and Solar System topics in middle school science education. Using the Research and Development (R&D) approach with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), the study developed AR media designed to enhance student understanding of complex scientific concepts. The effectiveness of the AR media was assessed through Aiken's V validation, practicality tests from teachers and students, and pre-test and post-test evaluations. The results showed that the AR media significantly improved student engagement, understanding, and academic performance. Aiken's V validation scores for usability, information, and interaction quality were above 0.8, indicating that the media was valid and effective. The practicality test revealed that teachers rated the media highly (93% usability), while students gave slightly lower ratings (81% usability). The N-gain score from pre-test and post-test evaluations showed a 56.2% improvement in students' knowledge, confirming the positive impact of the AR media on learning outcomes. Despite the challenges with usability for some students, the overall feedback supports AR's potential in enhancing science education, especially in rural settings. The study recommends further research to overcome usability challenges and optimize AR's classroom integration.

This study explores the development of Kodular-based learning media to enhance the quality of informatics education. The study addresses the need of more engaging learning media and better technology integration in teaching using a Research and Development (R&D) design and a modified 3D model out of the 4D development model, including defining, designing, and developing. The research involved 20 students from SMK Negeri 1 Bangkinang, employing all stages of the development model: need analysis, media development, validation, and trial to students. The defining stage revealed inappropriate teaching method uses, leading students to have less motivation in learning. Consequently, this research developed learning media, focusing on number systems material (decimal, binary, octal, hexadecimal), organized in a visually appealing and concise format. In the designing phase, the Kodular media was developed to be user-friendly, featuring quizzes, exercises, and interactive modules. Validation results showed high feasibility scores, with media experts rate on 88.57% and material experts rate on 95%. During the developing stage, a trial to students yielded a score of 4.81 out of 5, classifying the media as "Very Good". Students praised its clarity, ease of use, and ability to make learning enjoyable. This study highlights the potential of Kodular-based media to increase engagement and support student-centred learning in vocational education.

This research aims to design and implement a web-based information system for domestic sea transportation services of goods owned by a Limited Liability Company. Currently, the Limited Liability Company faces challenges in administrating goods due to the time-consuming recording process and using Excel applications that are prone to manual errors, accompanied by inaccuracies due to the absence of an integrated database system. The information system developed uses the waterfall approach for system design and the Unified Modeling Language (UML) for modelling, resulting in a requirements analysis, UML-based system design, and eight database tables that support system functionality. The use of PHP programming and MySQL database in the system implementation resulted in a web application that allows PT NSE to manage administration in a timely and accurately, with reports stored in the database. To enhance the executive dashboard of the domestic sea transportation service information system for goods, revamping the display for more visual and informative data presentation is essential. Additionally, integrating an Excel export feature will facilitate further data processing by relevant parties. Adequate resources must be allocated to maintain and manage the system effectively, ensuring seamless and sustainable operation. By implementing this information system, the Limited Liability Company is expected to boost administrative efficiency and accuracy, thereby solidifying its position in Indonesia's logistics service industry.
