Abstract
Ocean waves are a natural phenomenon that significantly affects marine activities, navigation safety, and disaster mitigation in coastal areas. Problems arising from ocean waves, such as coastal abrasion and potential hazards for fishermen, demand the development of accurate and real-time wave monitoring systems. This research aims to develop an Internet of Things (IoT)-based sea wave height detection device capable of remotely monitoring waves wirelessly. The main innovation in this study lies in improving the measuring device’s performance by replacing the previously used JSN-SR04T ultrasonic sensor with the URM14 RS485 sensor, which offers higher accuracy and resolution. The system is controlled by an ESP32 microcontroller and integrated with the Blynk platform to visualize real-time data on mobile devices. Data collection was carried out by strategically placing the sensor above a flume tank to obtain more stable and representative wave height data. The test results showed that the system was able to detect changes in wave height accurately, with a low average error of 0.0846% and an average accuracy of 99.91%. With this system, ocean wave monitoring can be conducted efficiently and is expected to become a key support tool for maritime decision-making and coastal disaster mitigation.

| Additional Information: | Gelombang laut merupakan fenomena alam yang memiliki pengaruh signifikan terhadap aktivitas kelautan, keselamatan pelayaran, serta mitigasi bencana di wilayah pesisir. Permasalahan yang muncul akibat gelombang laut, seperti abrasi pantai dan potensi bahaya bagi nelayan, menuntut adanya sistem pemantauan gelombang yang akurat dan real-time. Penelitian ini bertujuan untuk mengembangkan alat pendeteksi ketinggian gelombang air laut berbasis Internet of Things (IoT) yang dapat memantau gelombang secara jarak jauh tanpa kabel (wireless). Inovasi utama dalam penelitian ini terletak pada peningkatan performa alat ukur dengan mengganti sensor ultrasonik JSN-SR04T yang sebelumnya digunakan dengan sensor URM14 RS485 yang memiliki akurasi dan resolusi lebih tinggi. Sistem ini dikendalikan oleh mikrokontroler ESP32 dan terintegrasi dengan platform Blynk untuk memvisualisasikan data secara real-time pada perangkat seluler. Pengambilan data dilakukan melalui penempatan strategis sensor di atas flume tank guna mendapatkan data tinggi gelombang yang lebih stabil dan representatif. Hasil pengujian menunjukkan bahwa sistem mampu mendeteksi perubahan tinggi gelombang secara akurat dengan rata-rata error yang rendah yaitu 0,0846 % dan nilai akurasi rata rata yang mencapai 99,91 %. Dengan sistem ini, diharapkan pemantauan gelombang laut dapat dilakukan secara efisien dan menjadi pendukung utama dalam pengambilan keputusan kegiatan maritim dan mitigasi bencana pesisir | |||||||||
