Abstract

Indonesia is a renowned tourist destination worldwide. However, the COVID-19 pandemic has resulted in a decrease in both foreign and domestic tourist visits. Therefore, this research aims to develop a Telegram-based ChatBot application to increase post-pandemic tourist visits. The ChatBot is designed to make it easier for tourists to obtain information related to transportation and accommodation at tourist attractions. The ChatBot is built using the Knuth-Morris-Pratt (KMP) algorithm and web scraping method. The ChatBot's response to the keyword matching is then presented to tourists. To measure travelers' perceptions of ChatBot, the System Usability Scale (SUS) was used. SUS is a questionnaire consisting of 10 questions that were answered by 20 anonymous users. Based on the calculations, the average SUS score is 71, which indicates that the developed ChatBot is in the good category and suitable for use. Using this ChatBot will make it easier for tourists to obtain tourism information in Indonesia. With its ability to retrieve relevant information related to transportation and accommodation at tourist attractions, the ChatBot can serve as a useful tool to increase post-pandemic tourist visits.

Abstract

Rapid technological advancements in electrical engineering education require innovative learning media that bridge the gap between theoretical concepts and practical applications, especially for complex topics such as low-power inverters. This study developed and evaluated an AI-integrated learning media for low-power inverters, utilizing the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The media's effectiveness was assessed through a single-group pretest-posttest design involving 40 undergraduate electrical engineering students. Validation by content and media experts deemed the media highly feasible, with an average feasibility percentage exceeding 85%. The implementation results showed a significant improvement in students' cognitive competencies, with the average test score increasing from 59.75 (pretest) to 83.20 (posttest) and an N-Gain of 0.59, which is categorized as moderate. A paired-sample t-test confirmed a statistically significant difference (p < 0.05) between the pretest and posttest results. Furthermore, students' perceptions were very positive, especially regarding material understanding, learning motivation, interactivity, and self-directed learning. The novelty of these findings demonstrates that integrating artificial intelligence into learning media is not only technically and pedagogically feasible but also effective in improving the learning outcomes of electrical engineering students. The developed media has the potential for broader application in engineering education and supports continued innovation in smart technology-based learning environments.

Abstract

This study investigates the impact of integrating APBL with a PWM-controlled three-phase inverter project in vocational engineering education. This study was conducted across six vocational high schools in Indonesia and adopted a quasi-experimental, mixed-methods approach involving 223 students from the Industrial Electronics Engineering programs. The intervention was structured into sprint cycles, following APBL principles, which emphasized collaboration, iterative problem-solving, and hands-on experience. Data were collected through pre- and post-tests, student perception questionnaires, activity observations, product assessments, and semi-structured interviews. Results show a significant improvement in students’ technical competencies, with average pretest and posttest scores rising from 59.2 to 83.7 and a mean N-Gain of 0.60, classified as moderate. The paired-sample t-test indicated a large effect size (Cohen’s d = 2.03, p < 0.001). Students reported positive perceptions of motivation, teamwork, and problem-solving skills, supported by high mean activity observation and project assessment rubrics scores. The qualitative findings from the interviews highlighted enhanced engagement, collaboration, and autonomy. The study concludes that APBL is highly effective in bridging the gap between theory and practice in power electronics education when combined with technology-enhanced learning media. Recommendations for broader adoption and future research into long-term and scalable implementations of APBL in diverse educational contexts are provided.

Abstract

Gas leaks are one of the risks that occur due to improper installation of LPG cylinders. Therefore, a fast and reliable gas leak detection tool with an Internet of Things (IoT)-based approach is needed as an effective solution. This study designed a tool based on the Arduino Uno microcontroller and the Esp8266 module for remote gas leak monitoring. The gas sensor is used for real-time leak detection and sends warning notifications through the IoT network. The application of IoT technology in this system not only improves the safety of LPG use but also allows integration with modern technological developments. This tool is an innovative solution in creating a safer and more efficient environment in LPG cylinder installation.
