Abstract

Ketinggian air laut selalu berubah-ubah, tergantung pengaruh dari aspek meteorologi, gaya gravitasi, serta pengaruh geologis. Pemantauan terhadap ketinggian air laut sangatlah berguna, terutama bagi negara kepulauan besar seperti Indonesia. Sistem pemantauan ini didesain untuk menggunakan sensor accelerometer dalam mendeteksi perubahan ketinggian air laut dalam posisi vertikal, untuk mendapatkan data perubahan ketinggian dalam periode waktu tertentu. Alat ini juga dilengkapi dengan koneksi internet, yang memungkinkan data untuk diproses di tempat menggunakan mikrokontrol Arduino dan mengirimkan hasil data ke internet untuk proses pemantauan online. Riset ini menggunakan metode eksperimental, yang berfokus pada desain sistem elektronika. Proses riset dimulai dengan studi literatur dan perumusan masalah, kemudian dilanjutkan dengan desain sistem, desain software, persiapan website online dan integrasi perangkat lunak dan perangkat keras. Langkah terakhir adalah untuk melakukan uji coba pada alat dan menganalisa hasil uji coba. Setelah adanya uji coba dengan sistem katrol sederhana, ditemukan bahwa alat pemantauan ini dapat mendeteksi perubahan ketinggian dengan baik, dengan adanya galat pada sensor itu sendiri sekitar 6 cm atau sekitar 2% error. Tetapi terdapat masalah konektivitas antara alat dengan internet sehingga menimbulkan adanya hambatan dalam pemrosesan, menyebabkan sistem pemantauan online tidak bekerja sesuai harapan.

Sea level is always changing, either influenced by meteorological aspects, gravitational forces, or geological effects. Monitoring the sea level is very beneficial, especially in such a big archipelago as Indonesia. This monitoring system is designed to use accelerometer sensor to sense the sea level changes vertically to obtain the level changes over time. This device is also featured by internet connection so that the data obtained from the sensor could be process on site using Arduino microcontroller and then sent to online website for remote monitoring process. This research is using experimental method, focusing on the electronic system design. The working flow of the research is started with literature studies and problem statement, then followed by system design, continued to software design, server building, and software and hardware integration. The last step is to test the device and analyze the result. After trial using simple pulley system, it is found that this device is able to sense the vertical level changes well, with an error for the sensor itself is at most 6 cm or about 2%. But there are some connection problems occurred between the device and the internet which resulted in a delay on the process, making the online monitoring system not perform as desired.
