“…Here, several Manning's coefficients (0, 0.1, 0.2, 0.3) are used to see the ability of mangrove forests to attenuate waves. In real-life situations, the Manning's coefficient is determined by using the Morison equation based on field observation of mangroves [21]. The denser the mangrove forest as a wave absorber, the greater the coefficient value used in the simulation, and vice versa.…”

Coastal ecosystems, specifically mangrove trees, safeguard coastal regions against natural disasters like erosion, floods, and tsunamis. Numerical simulations employing the Shallow Water Equation (SWE), encompassing mass and momentum conservation equations, are used to comprehend how mangroves attenuate wave energy. The SWE incorporates Manning's friction term, which is directly influenced by mangrove forests. However, the SWE's complexity and sensitivity to initial conditions hinder analytical solutions. Despite its increasing computational demands, we utilize the robust staggered grid method to address this challenge. Our study examines mangroves' wave-attenuating effects and introduces a parallel computational model using OpenMP to expedite computations. Findings reveal that mangroves can reduce wave amplitudes by up to 33% when employing a Manning's coefficient of 0.3 within confined basin simulations. Furthermore, our parallel computing experiments demonstrate substantial computation speed enhancements; the speedup improves up to a point, with a notable 7.26-fold acceleration observed when utilizing eight threads compared to a single line. Moreover, more than a 10-fold acceleration is observed when the number of threads is greater than 16. This underscores the significance of parallelization in exploring mangrove contributions to coastal protection.

Pekalongan River has two functions, i.e., as fishing boat transportation and the main drainage of Pekalongan City. The Pekalongan river estuary has a Jetty located on two sides of the river mouth. The jetty is used to protect from waves and sediment. The Pekalongan river has upstream flow from Kupang and Banger river. Because of the flood incident around 2003, Since 2014, the two rivers became two estuaries. The condition caused a negative impact on sediment in the river mouth. Therefore, this research aims to find solutions by simulating waves, currents, and sediments. In this paper, the focus is on the wave simulation. This research method begins with the collection of primary data in the form of bathymetry measurements at the river mouth. While the secondary data is wind data for 13 years and tidal. Calculation of wind hindcasting figures out a wave at a significantly high value of 1.38 m and a significant period of 4.80 seconds. For wave simulations, it used SMS software in the CGWAVE module. The simulation compares the two jetties condition, in existing and development conditions. Based on the simulation, the wave is still high for existing conditions and becoming low by an extended jetty of 200 m lengths. The simulation results can be used to analyze the movement of sediment transport that is affected by the movement of waves around the river mouth.
