Abstract
Pasang surut air laut merupakan salah satu fenomena penting dalam berbagai bidang, seperti perencanaan pelabuhan, pembuatan peta laut, dan survei batimetri. Akan tetapi, stasiun pengamatan pasang surut di Indoensia masih belum merata sehingga pengambilan data pasang surut biasanya menggunakan palem pasut untuk mengamati pergerakan permukaan air laut. Metode tersebut memiliki kekurangan, yaitu secara visual kemampuan pengamat dalam menafsirkan bacaan pasut berbeda-beda atau bersifat subyektif. Solusi dari permasalah tersebut adalah instrumen pasang surut yang otomatis dan memberikan data real-time dan akurat sehingga menghemat tenaga dan waktu. Namun kendala yang menyertai penggunaan instrumen otomatis tersebut adalah tidak terjangkaunya harga yang ditawarkan di pasar Indonesia . Oleh karena itu, penelitian ini merancang low-cost automatic tide gauge dari integrasi sensor ultrasonic dan sensor tekanan serta dilengkapi dengan modul GPS. Data hasil pengukuran instrument terhubung dengan website thingspeak agar dapat melakukan monitoring secara real-time. Pengujian instrumen bersamaan dengan pengamatan manual menggunakan meteran. Dalam pengolahan data, penggunaan metode moving average untuk menyaring data dari noise dan outlier. Uji ketelitian instrumen akan dilakukan dengan membandingkan data pasang surut Badan Informasi Geospasial dan pengamatan manual dengan data bacaan instrumen, perbandingan nilai pasang surut yang dilakukan akan menggunakan perhitungan Root Mean Square Error atau RMSE. Berdasarkan hasil uji ketelitian instrumen, menghasilkan nilai RMSE dengan data BIG sebesar 13,590 cm untuk data pengamatan sensor ultrasonic dan 27,480 cm untuk data sensor tekanan. Sedangkan nilai RMSE dengan data pengamatan manual sebesar 1,875 cm untuk data sensor ultrasonik dan 13,535 cm untuk data sensor tekanan.

Tides are essential in many fields, such as port planning, nautical charting, and bathymetry surveys. However, tidal observation stations in Indonesia are still uneven, so tidal data collection usually uses tide palms to observe the movement of sea levels. This method has shortcomings, namely visually the ability of observers to interpret tidal readings is different or subjective. The solution to this problem is an automatic tidal instrument that provides real-time and accurate data, saving labor and time. However, the obstacle that accompanies using these automatic instruments is the unaffordable price offered in the Indonesian market. Therefore, this study designed a low-cost automatic tide gauge from the integration of ultrasonic and pressure sensors equipped with a GPS module. The measurement data from the instrument is connected to the Thingspeak website for real-time monitoring. Testing the instrument along with manual observation using a meter. In data processing, the moving average method is used to filter data from noise and outliers. The instrument accuracy test will be carried out by comparing the Geospatial Information Agency tidal data with the instrument reading data. The comparison of tidal values carried out will use Root Mean Square Error or RMSE calculations. Based on the instrument accuracy test results, the RMSE value with BIG’s data is 13.590 cm for ultrasonic sensor observation data and 27.480 cm for pressure sensor data. The RMSE with tidal observation is 1.875 cm for ultrasonic sensor observation data and 13,535 cm for pressure sensor data.
