Abstract

The purpose of this study is to evaluate how effective the laboratory information system is in terms of data transmission and website speed at the UNTIRTA VTE Laboratory. To conduct this study, a literature review and direct observation of the data sending and receiving process, as measured by PageSpeed ​​Insights, were used. The results showed that overall, the website performance was good, with optimal FCP and LCP values ​​on desktop and mobile devices. However, elements such as Interaction to Next Paint (INP) and Speed ​​Index (SI) require additional improvements to improve interactivity and access speed. The student dashboard page is considered the main activity center, according to the analysis of user access pattern data. However, pages with large file sizes require better data transmission management to avoid bottlenecks. The student dashboard page is considered the main activity center, according to the analysis of user access pattern data. However, pages with large file sizes require better data transmission management to avoid bottlenecks. This study provides an overview of how effective data transmission and user experience are on the laboratory website and suggests the development of infrastructure and website optimization elements, such as caching and file size reduction. These results contribute to the continuous improvement of the laboratory website, which is very important to meet the data and information service needs of UNTIRTA VTE Laboratory users in real-time.

Abstract

Steam Power Plant (SPP) material is considered a complex topic because it involves thermodynamic concepts and mechanical processes occurring within closed components, making it difficult for students to observe directly. This study aims to develop and evaluate the feasibility of interactive technology-based learning videos as supporting media in electrical engineering education. The research employed a Research and Development (R&D) method using the ADDIE development model, which consists of Analysis, Design, Development, Implementation, and Evaluation phases. The analysis phase identified students’ needs to visualize the water-steam cycle and understand the operational processes of steam power plants. During the design phase, storyboards and animation concepts for the main SPP components were created. The development phase produced interactive learning videos using Canva and CapCut, which were validated and deemed feasible by subject matter experts and media experts. The implementation stage demonstrated that the media could be effectively integrated into the learning process. Furthermore, the evaluation results revealed highly positive student responses, with an average score of 4.4 out of 5.0. Based on these findings, the developed interactive learning video is considered feasible, practical, and effective in enhancing students’ understanding of Steam Power Plant concepts.
