- Tuban Regency is one of the North Coastal areas of East Java, a lowland area whose elevation is almost the same as the sea level. Coastal areas are often used for various activities, such as residential areas, aquaculture, tourism, et cetera. Utilizing coastal areas requires good management because environmental conditions are influenced by many factors, such as wind, sea currents, tides, abrasion, sedimentation, et cetera. Case studies regarding differences in estimated surface temperature between MODIS imagery and in-situ measurements on the coast of Tuban can provide deeper insight into the region’s surface temperature characteristics. The research focuses on factors such as seawater temperature, land surface temperature, microclimate influence, and differences in spatial resolution between MODIS imagery and in-situ measurements. The result is that there is a significant difference between the Insitu Sea Surface temperature data compared to the Sea Surface temperature of the Aqua Modis 2023 image as shown by the t-test results, namely t count > t crit with a value of 16.64585558 > 1.729132812, H0 is rejected meaning there is a difference in sea surface temperature Insitu With Aqua Modis Image. Likewise, with the ANOVA test, it was found that in-situ sea surface temperature with Aqua Modis 2023 and Aqua Modis 2022, and Terra Modis 2022 image data, there is a difference in calculated F that is greater than F crit with a value of 2.142023> 1.729132812, H0 is rejected, meaning there is a significant difference between the four sea surface temperature data.
