Abstract

The earth has an ocean area larger than the land area so that there are many beaches found throughout the world, including Indonesia. Behind its beauty, there is one phenomenon that endangers tourists when doing activities on the near shore area, namely: rip current. For example, the incident at the research location, namely Klayar Beach, East Java, on January 2, 2015, claimed lives. Therefore, this study aims to validate the existence of rip current in East Java, especially at the research location by utilizing hydrodynamic modeling in the era of the industrial revolution 4.0 based on data, internet, and technology as well as human resources during this corona pandemic. There are 3 stages of the methodology in this research, namely data collection and processing, modeling, and modeling validation. The outcomes of this research prove that the phenomenon of rip current with rip current speeds occurs in the range 0.16 - 0.18 m/s which causes 2 tourists to die. It is hoped that the results of this research can be used as input for the stakeholder concerned for the development of coastal tourism in coastal areas on the south coast of East Java in making policies.
