Waves are movements of ups and downs of seawater that carry energy. This wave energy can erode the beach shore, including the Kenjeran Beach. The areas of eroded coast will depend on the magnitude of the energy of the waves. This research aimed to analyze wind and ocean waves for the management of coastal tourism areas, mainly related to visitor safety. This research used wind and wave data from BMKG obtained for ten years (2009–2018), and they were processed using Software ArcGis 9.3 and Software WRPOLT View 8.0.2. The statistical method used in this research was the Windrose method, which analyzed the wind direction and speed in a certain place and was the ratio of the wind blowing in each wind direction. The distribution of wind was intended to determine the significant wind speed and direction that have an effect in 10 years. The wind had an average speed of 5.31 m/s from 2009 to 2018. The variation in the dominant wind direction movement occurred in the range of 90° to 270°, but overall, the wind came from the East and Southeast. The highest ocean waves caused by wind in the Kenjeran tourism area were 0.8 m and occurred in 2014. It can be concluded that the wind and the ocean waves in the coastal tourism area of Kenjeran are relatively weak. Thus, in terms of security and safety for visitors, Kenjeran beach is very suitable for tourists.

Abstract

Waves are movements of ups and downs of seawater that carry energy. This wave energy can erode the beach shore, including the Kenjeran Beach. The areas of eroded coast will depend on the magnitude of the energy of the waves. This research aimed to analyze wind and ocean waves for the management of coastal tourism areas, mainly related to visitor safety. This research used wind and wave data from BMKG obtained for ten years (2009–2018), and they were processed using Software ArcGis 9.3 and Software WRPOLT View 8.0.2. The statistical method used in this research was the Windrose method, which analyzed the wind direction and speed in a certain place and was the ratio of the wind blowing in each wind direction. The distribution of wind was intended to determine the significant wind speed and direction that have an effect in 10 years. The wind had an average speed of 5.31 m/s from 2009 to 2018. The variation in the dominant wind direction movement occurred in the range of 90° to 270°, but overall, the wind came from the East and Southeast. The highest ocean waves caused by wind in the Kenjeran tourism area were 0.8 m and occurred in 2014. It can be concluded that the wind and the ocean waves in the coastal tourism area of Kenjeran are relatively weak. Thus, in terms of security and safety for visitors, Kenjeran beach is very suitable for tourists.
