Abstract

Based on data from the Indonesian Traffic Corps by September 2019, the number of car accidents was dominated by rear-hit crashes with 6,966 accidents. Most of these accidents occurred during car convoys. It needs a car-to-car communication to increase driver awareness. One of the technologies that can be applied is Visible Light Communication (VLC) and infrared communication. The transmitted data are the vehicle speed data, throttle position, and brake stepping indicator. The data are obtained by reading the Engine Control Unit (ECU) in the car. The data are packaged from the three data and sent to other cars at day and night using VLC and infrared communication. The experimental results show that in a communication system that uses VLC, data can be exchanged between cars during the day up to 2 meters and at night up to 11 meters. Otherwise, in infrared communication, vehicles can communicate during the day up to 2 meters and at night up to 0.7 meter. The test was also carried out with some conditions such as rain, smoke, passers, and other vehicle lights.

Abstract

Teknologi pengukuran kualitas air di lingkungan sekolah merupakan inovasi penting yang memungkinkan pemantauan kondisi air secara real-time, terutama dalam mengidentifikasi potensi pencemaran di sekitar sekolah. Dengan menggunakan sensor-sensor canggih untuk mengukur parameter seperti suhu, pH, oksigen terlarut, dan kekeruhan, sistem ini memberikan data yang akurat dan berkelanjutan. Data ini tidak hanya relevan untuk mendukung pembelajaran di kelas tetapi juga dapat digunakan untuk memantau kondisi lingkungan sekitar sekolah, mendeteksi adanya polutan, dan mencegah dampak negatif pencemaran air terhadap kesehatan ekosistem lokal. Kegiatan pengabdian masyarakat ini bertujuan untuk memperkenalkan alat ukur kualitas air digital di SMA Al Kautsar Labschool pada mata pelajaran Biologi. Sistem ini memungkinkan siswa untuk mempelajari dan menganalisis kualitas air secara langsung, serta memahami dampak pencemaran air terhadap ekosistem dan kesehatan manusia. Dengan demikian, program ini tidak hanya meningkatkan pemahaman siswa tentang ekosistem air tetapi juga memperkuat kesadaran mereka akan pentingnya menjaga kebersihan lingkungan sekitar sekolah. Melalui program ini, siswa mampu mengembangkan keterampilan dalam penggunaan alat ukur untuk penelitian ilmiah, serta meningkatkan kesadaran mereka tentang isu-isu lingkungan. Selain itu, kegiatan ini bertujuan untuk memperkaya metode pengajaran Biologi dengan memberikan pengalaman belajar yang lebih praktis dan interaktif, sehingga dapat berkontribusi pada peningkatan kualitas pendidikan sains di sekolah. Implementasi sistem ini juga diharapkan dapat menjadi langkah awal dalam Upaya pencegahan dan pengelolaan pencemaran lingkungan di sekitar sekolah.

Abstract

Changes in the quality of the lake environment due to human activities demand efficient and sustainable monitoring solutions. This research designed a navigation guidance system for the solar autonomous boat that operates independently using solar energy and designed as a modular navigation unit to support future swarm-based cooperation between multiple vessels. The system relies on GPS ATGM336H and GY-271 digital compass sensor as positioning and direction determinants, controlled by a TTGO ESP32 LoRa microcontroller. Navigation data is processed in real-time and sent over the LoRa network to a central or intership gateway. This research focuses on the development and validation of the autonomous navigation core, providing the necessary guidance capabilities for integration into a swarm unmanned surface vehicle (USV) framework. The test results showed that the boat could follow the destination's direction with an accuracy of 92%, where most of the trajectory was within the pre-programmed directional tolerance. The average direction error was recorded at 5.4 degrees, within acceptable tolerance limits. The system can adaptively maintain a stable heading and respond to aquatic environmental conditions. By establishing this stable autonomous navigation baseline, the system provides a scalable platform for future swarm implementations aimed at improving large-scale environmental monitoring. This system is considered successful as an intelligent and sustainable autonomous navigation solution.
