Abstract

The development of cellular communication technology has reached a significant point with the presence of 4G LTE networks, which offer high speed and spectrum efficiency. This study aims to evaluate the performance of 4G LTE networks from two operators, Telkomsel and Axis, at two locations of Sultan Ageng Tirtayasa University (UNTIRTA), namely Campus A and Campus C. The method used is a drive test with the help of the SpeedOf.me site, which measures download speed, upload speed, and latency parameters. The test results show that Telkomsel excels in upload speed with relatively good latency stability, while Axis has the advantage in the highest download speed but shows large fluctuations in performance, especially in the latency parameter. This performance variation indicates that location factors, network load, and device conditions greatly affect service quality. Overall, Telkomsel shows more stable performance, making it more reliable for network-based academic activities, while Axis is suitable for needs with a priority of download speed in optimal conditions. This study is expected to be a reference for the development of network infrastructure in higher education environments.

Abstract

Geothermal Power Plant (PLTP) subject matter is characterized by its highly technical nature, involving thermodynamic cycles, mechanical systems, and energy conversion processes that pose significant comprehension challenges when taught through traditional classroom methods. To bridge this gap, this study developed video-based instructional media using the ADDIE model framework (Analysis, Design, Development, Implementation, Evaluation) within a Research and Development (R&D) paradigm. The systematic development process began with identifying learning gaps and mapping instructional content, followed by creating a structured video script, producing the media, conducting audience trials, and carrying out a feedback-based evaluation cycle. Evidence gathered from the study confirms that the produced media fulfilled validity, practicality, and effectiveness criteria in fostering students' conceptual mastery of geothermal electricity generation. Combining motion graphics, narration, and on-screen text enabled learners to engage meaningfully with technical components including turbines, condensers, cooling towers, and synchronous generators. The ADDIE-based video media is therefore recommended as a reliable instructional resource for teaching the principles and operational dynamics of Geothermal Power Plants.
