Abstract

This paper presents an innovative smart key system designed to enhance the safety and convenience of hotel guests. The system employs an iterative, agile approach encompassing the phases of requirement analysis, design, implementation, and testing. Key components of the input circuitry include limit switches, RFID-RC522 and SW420 vibration sensors, which collectively gather data. This data is processed using an Arduino Uno microcontroller and integrated with internet of things (IoT) technology. On the output side, the system incorporates a solenoid lock and is capable of promptly notifying users via Telegram in response to unauthorized access attempts. Importantly, the system can distinguish between vibrations caused by unauthorized entry and those from legitimate usage. Rigorous testing validates its efficacy, issuing Telegram alerts promptly when detecting security breaches. This technological advancement significantly enhances hotel room security, providing an intelligent real-time solution. The fusion of IoT, Arduino microcontroller, and precise sensor configuration underscores the system's reliability, setting new benchmarks for security in the hospitality sector. The comprehensive approach detailed in this paper offers valuable insights applicable to a wide range of security applications.

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.
