“…The components on this microcontroller are almost like an ordinary computer device that has a Central Processing Unit (CPU), also equipped with RAM, ROM, and input and output devices (IO ports) that can be programmed as needed. The use of this microcontroller is generally applied to devices that require automatic control [27]. The microcontroller ESP32 module is the successor of the ESP8266 module which is quite popular for IoT applications.…”

The limited availability of real-time wave data is needed for shipping safety and for planning coastal areas. This wave data monitoring system including the wave height and direction gained to be used as a consideration in making decisions related to shipping safety and coastal management. This study aims to design and create a prototype of a simple mini-wave gauge and test the performance of a mini-wave gauge on the laboratory scale. The sensors used in this mini-wave gauge were ADXL335 as a vibration sensor to detect wave movement and the GY-271 sensor module with the HMC5883L chip which was a direction sensor. In the experiment, the wave data generated by the sensors were then received by the microcontroller ESP32 as a data processing center. The wave data was then received by the computer using a Wi-Fi network as well as processed and displayed on an application that had been developed using Embarcadero Delphi. Experiments with this mini-wave gauge resulted in an average range of wave height ± 6cm with a wave trough of -4.5 cm and a wave crest of 2.2 cm. This mini-wave gauge was then validated with the ultrasonic sensor at laboratory scale and the root mean square error obtained was 1.34 cm. Generally, this device functions well and has high accuracy for recording wave data.

“…In 2020 there was also research (Benesha et al, 2020) which engineered a virtual lab for sports science using wearables and IoT, demonstrating the design and construction of experiments, along with prototyping software solutions that can all be operated remotely using a web-based client. The last research is (ABEKIRI et al, 2023) who developed a low-cost platform called LABERSIME that is installed in the cloud (LMS, IDE) and equipped with embedded systems to drive real laboratory equipment and conduct experiments qualitatively more efficiently compared to the face-to-face mode. In this context, research on learning using IoT-based virtual science laboratories, especially on nervous system material is very important to be developed and implemented.…”

This study aims to test the effectiveness of the Internet of Things (IoT)-based virtual science laboratory on nervous system material in science lectures. The research method used was an experiment with a pretest-posttest control group design, with the research subjects being randomly selected A3 and A4 class students in the PGRI Yogyakarta University PGSD study program who take science courses. Data was collected by giving a pre-test and post-test and measuring n-gain to determine the increase in concept understanding after using a virtual science laboratory. Data analysis was carried out using the t-test to test the significant difference between the pre-test and post-test results and the n-gain test to measure the effectiveness of virtual science laboratories in improving students' concept understanding. The results of this study indicated that the Internet of Things (IoT)-based virtual science laboratory on nervous system material effectively improves students' understanding of concepts. It can be seen from the average n-gain result of 0.72 in the experimental group, which shows a high increase in concept understanding. The t-test results showed a significant difference between the control group and the experimental group in terms of the effectiveness of the IoT-based virtual science laboratory on nervous system material.

“…However, the pandemic has created gaps in education, both in keeping pace with theoretical-practical learning and in the impossibility of conducting expensive experiments in traditional laboratories. This has prompted the innovation of new pedagogical engineering strategies, particularly remote laboratory implementation (ABEKIRI et al, 2023. ) These laboratories allow students to correlate theoretical knowledge with practice, even in complicated situations like those faced by the pandemic.…”

The COVID-19 pandemic had a significant impact on education worldwide, prompting the adoption of virtual learning at all educational levels as a solution to overcome distance barriers, providing flexible study schedules and producing digital content to support adaptive learning. Educational institutions quickly adjusted their curriculum to enable uninterrupted learning in response to the new reality. However, implementing virtual education was challenging, particularly in terms of technology accessibility. Not all students had access to appropriate devices and connectivity, leading to a digital divide. Additionally, the lack of face-to-face interaction posed challenges for students as they adjusted to diverse learning platforms and grappled with uncertainties about the pandemic's impact on their future. The isolation also affected curricula, resulting in the cancellation of corporate internships and hands-on activities, particularly in engineering disciplines that rely on practical components. As a result, engineering institutions and educators advocated for methodologies that incorporate virtual and distance learning tools. Two noteworthy alternatives are Virtual Laboratories and Remote Laboratories. Virtual laboratories employ simulators to replicate real environmental conditions, while remote laboratories enable students to manipulate experiments in authentic laboratories via the Internet remotely. This study focuses on developing a remote laboratory for hands-on practices in control engineering, specifically involving a DC motor, using the Internet of Things (IoT) protocol. The laboratory incorporates a motor connected to a development board with MQTT protocol-based messaging services, a lightweight and widely used IoT protocol. The laboratory's web page hosted on the server facilitates data transmission and reception, along with real-time video streaming for users to observe the motor's operation. By using the remote laboratory, students gain access to a standardized control device, enabling the application of theoretical knowledge in control systems. They can experimentally determine system transfer functions through identification or modeling, design controllers, and test them on the physical platform, all from the comfort of their homes. To summarize, remote laboratories have been valuable tools in engineering education, addressing the challenges caused by the COVID-19 pandemic. These laboratories enhance the learning process by providing access to practical experiences and advanced resources, consolidating theoretical concepts, and offering students greater flexibility in their educational journey.
