Abstract

The primary issue in technology-based learning assessment is the limited ability of teachers to utilize and develop gamification methods. Most teachers still rely on manual, paper-based evaluation techniques, resulting in suboptimal integration of technology in the assessment process. This challenge necessitates further exploration by education practitioners regarding the implementation of information technology (IT) in learning, particularly for MGMP Informatics teachers. This community engagement program, titled "Development of Internet-Based Testing (IBT) Using Gamification Learning Methods", was conducted at SMPN 1 Tanah Datar. The objectives of this program were to: (1) enhance technological literacy in the education sector; (2) strengthen interest and skills in technology literacy among MGMP Informatics teachers at the junior high school level in Tanah Datar Regency; and (3) improve teachers' ability to design internet-based assessment instruments using a gamification approach. The program was implemented using a participatory approach, comprising training sessions, interactive workshops, and hands-on practice in developing internet-based assessment tools. Participants were introduced to various digital evaluation platforms, such as Google Forms, Quizizz, and Kahoot, and were trained on how to integrate gamification elements into learning assessments. The results indicated that 85% of participants showed an improvement in their understanding and skills in utilizing internet-based assessment technology. Additionally, teachers began adopting gamification methods in assessments, leading to increased student engagement in the learning process. This initiative is expected to encourage teachers to continuously develop innovative and interactive assessment methods aligned with technological advancements in education.

Abstract

Floating net cage (KJA) fish farming in Lake Maninjau faces several challenges, particularly the inefficiency of manual feeding—which requires significant time and labor and often results in uneven distribution—as well as water quality issues caused by pollution and upwelling (tubo) phenomena, leading to mass fish mortality. This study aims to develop an Internet of Things (IoT)-based prototype to automate feeding and monitor water quality, thereby improving farming efficiency. The prototype was built using the ESP32 microcontroller, DS18B20 temperature sensor, pH sensor, HC-SR04 ultrasonic sensor, DS3231 RTC module, servo motor, buzzer, LED, and LCD display, following the waterfall development model. Sensor validation was performed using standard instruments such as thermometers and pH meters. The Blynk platform was used for remote monitoring and control via smartphone. The system successfully monitored water temperature within the range of 27–32°C, pH between 6–8.5, and feed levels (0–100%), with a deviation of ±0.01 for pH and 0.0°C for temperature. A total of 150 grams of feed was automatically dispensed at scheduled times (09:00 and 16:00 WIB), with notifications sent via Blynk. These findings demonstrate that the developed system effectively supports more efficient, adaptive, and environmentally responsive fish farming.

Abstract

The rapid development of Internet of Things (IoT) technology requires learning media that are able to support practical competencies in flexible learning environments. However, IoT learning implementation in hybrid learning faces major challenges related to limited laboratory facilities and hardware availability. This study aims to develop IoT learning media based on hybrid learning using Wokwi Simulation as a virtual laboratory solution. The research employed a Research and Development (R&D) approach using the 4D development model, consisting of define, design, develop, and disseminate stages. The feasibility of the developed media was evaluated through expert validation and practicality testing. Validation involved three subject matter experts and three media experts, analyzed using Aiken’s V coefficient. The results showed that the learning media achieved high validity, with an average Aiken’s V value of 0.846 from material experts and 0.929 from media experts. Practicality testing conducted with 15 students resulted in a practicality level of 91.33%, categorized as very practical. These findings indicate that the developed IoT learning media is valid, practical, and suitable for supporting hybrid learning. The integration of Wokwi Simulation provides flexible access, reduces dependency on physical hardware, and enhances students’ learning experiences in IoT practical activities.Keywords— IoT, Hybrid Learning, Learning Media, Wokwi Simulation, Virtual Laboratory.

Abstract

This study developed and evaluated an integrated Internet of Things (IoT)-based access control system that unifies residential gate operation, garage door automation, and garage lighting within a single platform. Conventional home automation deployments typically address only one function at a time, resulting in fragmented control and limited interaction between subsystems. Compared to prior smart home implementations that focus on single subsystems, the proposed platform jointly manages gate, garage door, and lighting and reports scenario-based reliability metrics. To address this gap, the proposed system used an ESP32 microcontroller as the central controller, ultrasonic distance sensors for vehicle detection, servo motors for mechanical actuation, and a relay module for lighting control. A mobile application built with the Blynk platform provided real-time monitoring and remote control via smartphone. The prototype was tested under three scenarios-manual mobile control, fully automatic sensor-triggered operation, and combined operation-with 20 repeated cycles per scenario. Performance metrics included servo actuation time, communication latency between the mobile application and the ESP32, sensor accuracy, and operational reliability. The gate and garage door achieved opening times of approximately 1.0-1.2 s and 1.5 s, respectively, while end-to-end communication latency remained between 300 ms and 480 ms across all tests. Ultrasonic distance measurements showed a maximum error of 1.8 cm and an average error below 1.2 cm, with no system failures in any scenario. These results demonstrate that the integrated design is technically feasible, reliable, and suitable as a cost-effective foundation for residential access control.  Future work will focus on scaling the prototype toward full-size installations and extending integration with additional smart home services.

Abstract

Environmental problems caused by suboptimal waste management have become a major issue in Nagari Batu Basa, particularly the habit of residents disposing of waste into rivers. This condition worsens during the dry season, as waste accumulation generates unpleasant odors and poses health risks, especially from plastic waste that is difficult to decompose and has even contributed to malaria cases among some community members. This community service activity aims to increase public awareness of integrated plastic waste management and to discourage residents from disposing of waste into rivers. The methods employed consist of four approaches. The first approach involves the provision of educational waste posts as an initial effort to prevent indiscriminate waste disposal. The second approach is the construction of an integrated plastic waste collection facility at the nagari office, equipped with dry waste sorting facilities. In addition, the community was provided with training on ecobrick production, which could be exchanged for incentives. The fourth approach applies a door-to-door collection method through the involvement of KKN students from Universitas Negeri Padang (UNP), who collected waste that had been gathered by the community from shops, schools, and mosques. The results of the community service activities indicate positive community engagement, as evidenced by the successful production of 300 ecobricks by the community in collaboration with KKN UNP students, of which 260 were branded as Nagari Batu Basa ecobricks. This activity contributes significantly to building community awareness of household-level waste segregation and supports the creation of a healthier and more sustainable nagari environment.
