Perancangan Kontruksi dan Wave Breaker Pada Tangki Uji Multifungsi Arus-Gelombang

Abstract

There has been a lot of researches on Oscillating Water Column, but the studies of their
potential or feasibility installed on the beach are limited. However, research that examines the
standard size of the prototype tank to produce a combination of 2 laboratory-scale current and wave
simulation tools has not been found. Based on these conditions, this final project was carried out to
obtain the design of the tank and wave breaker in the test tank. The initial stage begins with
calculating the hydrostatic pressure, the weight of the tank in the fluid and sloshing. The result of the
stage is the test tank has dimensions of 6x2x1.5 m using 20mm thick acrylic material. The foundation
stiffener uses H beam material with a dimension of 300x300mm. The hollow profile used for the
longitudinal stiffener has a dimension of 132x132mm. E6013 type welding wire with a tensile stress of
206 kN is used for welding in the fabrication. Based on wave breaker calculation at deep water, the
mass is 18.424kg, and at intermediate water, the mass is 3.625.
