Abstract

Penelitian ini bertujuan merancang alat pengukur kecepatan arus air berbasis Long Range dan Internet of Things sebagai solusi pemantauan kondisi perairan secara real-time. Kecepatan arus air merupakan parameter penting dalam berbagai aktivitas kelautan dan perikanan, sehingga diperlukan alat ukur yang dapat digunakan dengan baik. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model V-Model, yang meliputi tahapan analisis kebutuhan, perancangan sistem, implementasi perangkat keras dan perangkat lunak, pengujian unit, pengujian integrasi, pengujian sistem, serta validasi. Sistem dirancang menggunakan sensor optik tipe celah untuk mendeteksi putaran baling-baling sebagai indikator kecepatan arus air, dengan Arduino Mega 2560 sebagai pengolah data, LoRa RA-02 SX1278 sebagai media transmisi, dan ESP32 sebagai gateway IoT yang terhubung ke Firebase Realtime Database. Data hasil pengukuran ditampilkan melalui Web Interface secara real-time. Hasil penelitian menunjukkan bahwa sistem berhasil dirancang dan diintegrasikan dengan baik serta menghasilkan faktor koreksi yang dapat digunakan untuk evaluasi pembacaan sensor. Kesimpulan dari penelitian ini diharapkan dapat menjadi dasar pengembangan sistem pemantauan kondisi perairan berbasis LoRa dan Internet of Things pada penelitian selanjutnya. ***** This study aims to design a water current velocity measurement device based on Long Range (LoRa) and the Internet of Things (IoT) as a solution for real-time water condition monitoring. Water current velocity is an important parameter in various marine and fisheries activities; therefore, a reliable measuring instrument is required. This study employed the Research and Development (R&D) method using the V-Model, which consists of the stages of requirements analysis, system design, hardware and software implementation, unit testing, integration testing, system testing, and validation. The proposed system utilizes a slotted optical sensor to detect the rotation of a propeller as an indicator of water current velocity, with an Arduino Mega 2560 serving as the main data processing unit, a LoRa RA-02 SX1278 module as the wireless communication medium, and an ESP32 functioning as an IoT gateway connected to the Firebase Realtime Database. The measurement data are displayed in real time through a web interface. The results indicate that the system was successfully designed and integrated, and a correction factor was obtained through the calibration process to improve the accuracy of the sensor measurements. In conclusion, the developed device is expected to serve as a foundation for the further development of LoRa- and Internet of Things-based water condition monitoring systems.
