Analisis Pola Sirkulasi Arus Di Perairan Selat Rupat

---

The Rupat Strait, functioning as a semi-enclosed water body connecting the Dumai coast with the Malacca Strait, exhibits complex hydrodynamic variability influenced by monsoon patterns, tidal forces, and anthropogenic pressures. Our integrated study combining MIKE 21 hydrodynamic modeling with field validation (demonstrating high accuracy: RMSE=0.27, MAE=0.23) reveals distinct seasonal patterns. During the west monsoon (December-February), the strait experiences peak hydrodynamic activity, with eastward currents reaching 0.51-1 m/s and extreme water elevation fluctuations up to 6.28 m during tidal transitions. In contrast, transitional and east monsoon periods show more stable conditions, with currents of 0.01-0.5 m/s and moderate elevation variations (±1.49-2.44 m), though localized acceleration (0.51-1 m/s) occurs near Ketam Island due to topographic effects. Tidal phase emerges as the primary driver of current variability, while significant bathymetric changes - including shallowing (≤6.6 m) and deepening (up to 17 m) - reflect combined sedimentation processes and human impacts. These findings establish the west monsoon as the most critical period for strait dynamics, highlighting how the interplay of monsoonal forcing, local bathymetry, and tidal regimes creates a complex hydrodynamic system requiring careful consideration in coastal zone management strategies to ensure navigational safety and environmental sustainability.
