The effect of porous round on waves produced on the wave simulation tool, laboratory scale

Abstract

Bangka Island is one of the islands that has beautiful beach tourism destinations but also has the largest tin reserves in the offshore area. This causes a very significant difference and can be a gift or a curse. Waste from the results of offshore tin mining activities carried out by production suction vessels (KIP) in the form of mud and changes in seawater quality. Then the sludge produced by mining causes waste/mud to be carried by the waves of the sea and settles along the shore and imposes silting and causes seawater on the shore to become turbid. One way to determine the effect of waves on the deposition of mud, among others, with a wave simulation tool. The study aims to determine the length and height of the waves produced on a laboratory scale Floating Breakwater Simulation. From the results of the study it can be concluded that the shaft rotation speed affects the waves produced, the higher the shaft rotation the higher the resulting waves. The frequency of the simulation tool also increases while the wave period decreases as the rotation of the shaft rotates, which means that the resulting wave appears more frequently and with a high propagation speed at the highest rotation of the shaft.
