Abstract

East Java Province has the potential for a large capture fisheries industry which is supported by its strategic location because it is bordered by the Java Sea, Bali Strait, and the Indian Ocean. The existence of climate change is allegedly having a direct or indirect impact on capture fisheries. Climate change causes an increase in sea surface temperatures, an increase in extreme weather events and their intensity, changes in precipitation patterns, and freshwater runoff. Based on this, it is necessary to carry out an analysis to determine the effect of temperature (X1), rainfall (X2), humidity (X3), and sunlight (X4) simultaneously and partially on fish production in East Java Province, Indonesia. This research method is descriptive using multiple linear regression analysis, F test, and t-test. The results showed that the data were normally distributed and there was no multicollinearity in the independent variables. The resulting linear regression equation is y= -1775919,888 + 21619,513X1 – 160,916X2 + 30558,699X3 – 4664,191X4. The results of the F test show a significant value of 0.000, which means 0.000 <0.05 so all independent variables have a significant effect simultaneously on the dependent variable. The t-test shows that the temperature (X1) and solar radiation (X4) has no partially significant effect on the dependent variable. While the variables humidity (X2) and rainfall (X3) have no partial significant effect on the dependent variable, namely capture fisheries production.

Abstract

Regarding fisheries in Indonesia, there is a need for balanced management so that existing resources can be used and utilized optimally. The Romokalisari Adventure Land tourist attraction, located in Benowo District, Surabaya City, is a tourist attraction that utilizes the balance between the two natural resources in the form of land and sea. The method used to find the economic value of resources in Romokalisari Adventure Land Ecotourism is a simple method, where there is a regression model to determine the influence of each factor and the Travel Cost Method (TCM) travel cost model to determine the economic value of resources. The results of this research show that the actual income obtained by Romokalisari Adventure Land Ecotourism is IDR. 120,000,000,- / year and potential income of IDR 720,000,000,-/ year. Potential income can also be generated by the emergence of potential that appears as an activity sector to expand economic income.
