Analisis Prediksi Pasang Surut Air Laut Di Perairan Makassar Dengan Metode Admiralty

---

ABSTRACT
Makassar is a coastal area so the influence of tides of sea water must be taken
into account. This research used Admiralty method with observation data every
hour during 29 days simulated on 101 data variation and 15 days 115 data
variation. Simulation data will be verified against several verifications, namely
verification of the data itself (Simulation 1), verification of other data in the same
year as simulation data (Simulation 2A), and verification of other data outside of
the simulation data year (Simulation 2B) . This study aims to determine the initial
time of observation that produces the most accurate predictive data. The results of
the analysis of the Root Mean Square Error (RMSE) value for 29 days were 9.10
cm on the 19 hijriah (Simulai 1), 4.62 cm on the 30 hijriah (Simulation 2A), and
23.31 cm on the 19 hijriah ( Simulation 2B). Meanwhile, for 15 days, it was 29.47
cm on the 15 days Hijriah (Simulai 1), 18.63 cm on the 30 Hijriah (Simulation
2A), and 29.93 cm on the 12th Hijriah (Simulation 2B). So that the smallest RMSE
value is found in Simulation 2A of 4.62 cm on 30 Hijriah. Therefore, the most
precise time to do tide observation in the field for the need of tide prediction is on
date of 30 of Hijri Calendar. The analysis of Fromzahl value shows that the
research location is included into classification of Mixed tide prevailing diurnal.
The analysis result of correlation coefficient for Simulation 1, Simulation 2A, and
Simulation 2B obtained the highest correlation value for simulation 1 with the
average of correlation value from date 1 – 30 of hijri calendar in each month >
0,90 which means it has an extremely strong correlation.
