Noise traffic is the main problem in urban area which resulted by vehicle traffic transportation. The impact of traffic noise covers auditory and non-auditory effect human’s life. In addition, high intensity of traffic noise has disturbed human social life ecologically. Feeling of annoyance resulted by high intensity of traffic noise will influence to the human behavior in driving of vehicles as indirect impact to human social life. In consequence, loss of life and material due to traffic accident is the part of human behavior. This study area is in Pekanbaru city where the relation between number of accident and growth of vehicle in each year indicating fluctuate condition. It can be concluded that the noise traffic impact associated with traffic accident ecologically.

Engineering marvels have led to the design and build the wing-in-ground (WIG) craft to fill the gap between ships and aircraft as a new opportunity for transportation. One of the most significant issues in WIG craft are drag and lift force when the craft starting to plane. Living nature has been used to solve the mentioned challenge. There are various ways in nature to reduce drag force in fluid flow, such as the evidence in the movements of fish, sharks and dolphins, the skin of fast-swimming sharks is covered by microriblets that assist them to move fast. In this study, Computational Fluids Dynamics (CFD) method is implemented to the investigation the influence of microriblet film on aerodynamic of the WIG craft. A Clark-Y wing was simulated in ANSYS CFX simulation software at various Reynolds number to investigate the effects of riblets on aerodynamic characteristics of the wing in ground effects.
