Abstract

Salah satu penyebab kerusakan pada lingkungan pantai seringkali terjadi dikarenakan faktor menomena alam seperti perubahan garis pantai, abrasi, dan erosi pantai. masalah tersebut diakibatkan oleh tingginya gelombang dan periode gelombang yang besar sehingga pantai mengalami erosi dan perubahan garis pantai. untuk menanggulangi dampak yang diakibatkan oleh kerusakan pantai, dapat dilakukan dengan upaya membuaat struktur pelindung pantai salah satunya artificial reef. pada penelitian ini dilakukan uji transmisi dan refleksi gelombang terhadap artificial reef berbentuk hexagonal dengan konfigurasi vertikal. pengujian ini menggunakan metode Smoothed Particle hydrodynamics (SPH) berbasis dualsphysics dengan variasi tinggi gelombang dan periode gelombang. hasil analisa menunjukkan nilai koefisien transmisi pada susunan 6 memiliki nilai 0.274-0.352, pada konfigurasi 63 nilai kt menunjukkan peningkatan dan pada konfigurasi 631 menunjukkan nilai kt yang rendah. pada konfigurasi 6 niali refleksi sebesar 0.597-0.336, pada konfigurasi 63 dan 631 menunjukkan peningkatan nilai refleksi gelombang, dan untuk susunan yang paling optimal yaitu susunan 631.

One of the causes of damage to the coastal environtmental often occurs to natural phenomena such as shorline changes, abrasion, and coastal erosion. The problem is caused by high waves and large wave periods so that the beach erodes and changes the coastline. To overcome the impact caused by coastal damage, efforts can be made to create coastal protective structures such as making breakwaters and artificial reef. In the research, the transmission and reflection of waves on the hexagonal shaped artificial reef with a vertical confguration were tasted. This test uses numerical modeling with dualsphysics based Smoothed Particle Hydrodynamics method with variations in wave height and wave periods. The result of analysis the value of transmission in configuration 6 has a value 0.274-0.352. in configuration 63 show a decrease in the velue of the transmission and configuration 631 shows improvement result with a value of 0.120. in configurations 6 has a reflection with a value 0.597-0.336. in configuration 63 and 631 show an increase in dampening and reflecting wave namely in configuraation 631.
