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.

Management of coastal areas on the east coast of Surabaya (Pamurbaya) is very important because this region is largely a conservation area which serves to maintain the balance of the ecosystem of Surabaya. This study aimed to analyze changes in the coastal land and create a dynamic model of coastal land area changes in Pamurbaya. The method used is the field survey, the linear regression method and dynamic modeling. Dynamic modeling using the software Stella 4.0. The results showed that the changing of used land can be explained by the dynamic model described by a linear regression model. The result is useful to predict the pamurbaya condition for next few years and useful as inputs to city government in managing coastal areas of Pamurbaya.

Data on capture fisheries in the southern region of East Java is a source of information that can be used to analyze the profile of fisheries that can be used as a reference in developing the port of fisheries especially in the southern region of East Java. The research objective was to determine the profile of fisheries in the southern region of East Java as the basis for the development of Fishery Port. The method used is descriptive analysis in order to obtain an idea of the profile of fisheries in the southern region of East Java. Potential data analysis and utilization of fisheries using Schaefer Methods. The results of the study are comparison of the eight districts in the southern region of East Java, Banyuwangi still dominate in the aspect of the number of fishing vessels, production and value of catch production and the number of fishermen. The Blitar district still lags behind in all aspects of fisheries. The dominant species of fish catches in the southern region of East Java include Lemuru (Sardinella sp), Tuna (Thunnus sp) Tongkol (Euthynus sp), Cakalang (Katsuwonus pelamis), and Layang (Decapterus sp). Potential and level of utilization of the fish in the south of East Java in the period 2009-2013 are still in a state of sustainable/under fishing. Development of fishing ports in southern Java needs to be supported entirely by the government, so it can improve fishermen's welfare and development of the economy in the region with the scale of priorities.
