Pengaruh Simulasi Awal Data Pengamatan Terhadap Efektivitas Prediksi Pasang Surut Metode Admiralty (Studi Kasus Pelabuhan Dumai)

Abstract

This research to examines the initial variation of observation data based on Hijri
calendar, because the initial time of observation data will affect the value of the resulting
tidal components. The data was simulated against one hundred and thirty-five variations
of observation time. The result of data analysis shows that the smallest RMSE value from
the verification result of the simulation data is found on the data of the early date of 12
Hijri calendar is when the phase of the first humpback moon. This indicates that the time
variation of the date of the observation of the matching observation data at the study site
is between approaching the full moon phase and after the full moon phase. The F value
indicates that the location of the study entered on the classification of the daily double
tide type (semi diurnal tide).
