Abstract

The aquaculture sector currently has a real contribution to foodsecurity, including increased production, animal protein consumption,employment, income and regional development. Some problems intilapia farming are manual feeding and unstable water pH levels. Thisresearch aims to design and build an automatic control system for fishfeeders and monitoring water pH in tilapia ponds based on the Internetof Things (IoT). This system uses a Raspberry Pi as the systemcontrol. In the feeding mechanism, the HX711 load cell sensor is usedto weigh the feed, the servo motor functions as the opening and closingof the main feed container, and the DC fan acts as a blower of theweighed feed into the pond area. In addition, a PH-4502C sensor isused to measure the acidity (pH) of the pond water in real-time. Alldata related to feed weight and water pH are displayed through a webserver interface that can be accessed remotely by users. This system isexpected to improve the efficiency of feeding and monitoring waterquality, thus supporting optimal tilapia growth. The test results showthat this system is able to operate well and provide accuratemonitoring results as well as timely feed control and in accordancewith the needs of tilapia.

Abstract

Clean water quality is an important factor for public health, but the problem of inconsistent PDAM water quality in Sijantang Koto village is still an obstacle. This research aims to design and build a prototype of an Internet of Things (IoT)-based water quality monitoring and control system. The system uses pH sensors and TDS sensors to measure water quality parameters in real-time. The data from the sensors is processed by the ESP32 microcontroller and displayed through LCD and Blynk application for remote monitoring. In addition to the monitoring function, the system is also equipped with an automatic control mechanism using a pump to add purifying agent (PAC) and pH neutralizer (CaCo3) when the water parameters are outside the standard threshold. The results show that the system is able to detect changes in water quality and automatically control water parameters according to the set standards. The implementation of this system is expected to increase public awareness of the quality of water used and provide solutions in a more efficient and modern clean water management.

Abstract

The need for an efficient and reliable weather monitoring system in areas with limited communication infrastructure has led to the development of an Internet of Things (IoT)-based solution utilizing LoRa (Long Range) technology. This study presents the design and implementation of a local-area weather monitoring system using the STM32F103C8T6 microcontroller and the LoRa RA-02 communication module. The system monitors environmental parameters such as temperature, humidity, wind speed, and air pressure using various sensors including DHT-21, BMP280, A3114, and INA219. Sensor data is collected by the transmitter node and sent via LoRa to a receiver node equipped with an ESP32 microcontroller. The receiver processes the data and sends it to the Blynk IoT platform and Google Sheets for visualization and storage. Experimental results show reliable transmission over distances up to 530 meters in dense environments and 2 kilometers in open areas. The system demonstrated low power consumption, making it suitable for solar-powered applications. The proposed solution is practical, flexible, and cost-effective, providing valuable support for weather-dependent decision-making in remote locations..

Abstract

Industrial electrical panels play a crucial role in electrical systems, particularly in power distribution and electric machine control panels that operate continuously during production processes. However, they also pose a potential fire hazard due to factors such as human error or equipment malfunction, including high temperatures, gas leaks, or undetectable installation errors. This study aims to design a fire alarm monitoring system based on the Internet of Things using an ESP32 microcontroller integrated with a DHT22 temperature and humidity sensor, an MQ-2 gas sensor, and a flame sensor. The research adopts an experimental method. A three-phase distribution panel is used in this study. Based on the test results, sensor data can be displayed in real time through an LCD and the Blynk application, and automatically logged to Google Sheets. The results demonstrate that the system is capable of detecting hazardous conditions and providing early warning alerts via an alarm

Abstract

The development of digital technology requires vocational education (SMK) teachers to be able to develop innovative learning media, such as QR codes, to support 21st-century learning. This community service activity aimed to improve the skills of teachers at SMKN 1 Padang Panjang in designing and implementing QR code-based digital learning media integrated with the Activities Digital Learning (ADL) concept. This activity involved 20 teachers through stages of socialization, training, workshops, hands-on practice, and mentoring. The materials covered AI-assisted digital module creation, media design (Canva), video production (CapCut), and QR Code integration into ADL. The results of the pre-test and post-test evaluation showed an average increase of 35% in teachers’ digital skills. Furthermore, each teacher successfully created at least one ready-to-use QR code-based learning media product. This program also successfully established a collaborative network among teachers to support the sustainability of digital innovation at the school.

Abstract

This research presents strong evidence supporting the effectiveness of video tutorial media in improving student learning outcomes within vocational education. By delivering content in a visually appealing and organized manner, video tutorials enhance student engagement and deepen conceptual understanding, especially in technical subjects. The study applied a quasi-experimental design with a descriptive quantitative approach to assess the influence of video tutorials on student performance in the Basic Electronics course. The participants included 45 tenth-grade students from the Industrial Electronics Engineering (TEI) program at SMKN 4 Pariaman. Data were gathered through post-test results and analyzed using an independent sample t-test to evaluate statistical differences between the experimental group (utilizing video tutorials) and the control group (employing traditional teaching methods). The findings indicated that students who used video tutorial media achieved significantly higher academic results than those taught through conventional approaches. These results highlight the potential of video-based instructional tools to support effective and modern teaching strategies in vocational schools. Moreover, the integration of such media not only boosts academic achievement but also encourages student independence and active involvement in hands-on learning experiences

Abstract

This research is motivated by the presence of students who have very little desire to learn, grades that are still below the Minimum Completion Criteria (KKM) and the media used by teachers are still conventional such as printed books and whiteboards. The purpose of this study was to determine the effect of the use of video tutor media on student learning outcomes. The method used in this study is a quantitative method with the type of Quasi Experimental Design Nonequivalent Control Group with a two group pretest-posttest design. The sample determination uses a purposive sampling technique. Purposive sampling is sampling based on research objectives/certain characteristics. The population of class X TEI is 45 people. The number of samples is 24 students divided into 2, namely 12 students for the experimental class and 12 students for the control class. The research was conducted in the 2024/2025 academic year in class X majoring in industrial electronics engineering. This study shows that the average post-test score of experimental class students is higher than the post-test score of the control class, which is 92.00> 67.33. From the results of the Independent Sample t Test on the post-test data, the t-count value is obtained = 3.844 and the Sig. (2-tailed) value is 0.001. The t-table distribution value is seen based on df = 22 with a significant level of ???? = 0.05 is 2.074. Because the t-count value> t-table (3.844> 2.074) and Sig. (2-tailed) 0.001 <0.05, Ho is rejected and Ha is accepted. From the results of the independent sample T-test, video tutorial media has an effect on the learning outcomes of basic electronic engineering subjects for class X TEI at SMK Negeri 4 Pariaman.
