The sampling technique used in this research is purposive sample. The research instruments used are test instruments in the form of multiple-choice questions, as well as non-test instruments in the form of observation and documentation. The results of the study showed that there was a positive influence in the application of the problem-based learning model using google earth media on the understanding of hydrometeorological disaster mitigation in class XI at SMAN 1 Tanjung Palas Tengah in the form of a significant increase in the average class score. This is based on the results of N-Gain obtained a value of 66.96% and the t-test obtained a value of Sig. (2-tailed) of 0.001.
