Sedimentation Analysis in Determining the Optimal Breakwater Layout for Grajagan Beach Fishing Port, Banyuwangi Regency

Sedimentation that occurs in Grajagan Fishing Harbor, based on Google Earth
images for the 2017-2023 time span tends to gather in the southern and eastern breakwater
areas. The existence of sedimentation around the harbor can hinder fishing boat traffic.
Sedimentation that occurs in the Grajagan Fishing Port area is thought to be less than optimal
in the existing breakwater layout so that an optimal breakwater layout is needed. This study
aims to determine the optimal breakwater layout based on hydro-oceanographic parameters
using quantitative descriptive methods. The data used, namely: tidal, wind, wave, and
sediment data. The data is used to analyze tidal patterns, wind and wave characteristics,
current distribution patterns, and sediments. The results of the analysis are for determining
the optimal breakwater layout. In Layout breakwater plan C sedimentation only occurs on
the west side of the breakwater up to 0.6 m, while in the shipping channel and the berthing
pond neither sedimentation nor erosion occurs. The simulation results of Layout breakwater
plan A, B, and C, for Layout breakwater plan C is the most optimal and efficient in
maintaining the berth pond for Grajagan Beach Fishing Port, Banyuwangi Regency.
