Geography material in senior high school is mostly abstract, one of which is the hydrological cycle material. Many teachers have not been able to provide optimal learning due to limited media. The purpose of this research is to determine the suitability of the material with the media and the feasibility of learning media and the level of understanding of high school students on the hydrological cycle material. The research location is in SMA Labschool USK by using a population of all students of class X Social Sciences SMA Laboratory USK, totaling 23 students. The research method uses the RnD (Research and Development) method with the ADDIE model design (Analysis, Design, Development, Implementation, Evaluation). The steps of this research; conducting interviews with geography teachers to find out the problems experienced by students, designing product designs for hydrological cycle learning media, developing products, testing products, testing students' understanding levels after using learning media. The results showed that; validation of the suitability of the material by experts obtained a value of 97.5% with the criteria of "Very Valid", validation of the media obtained a value of 80%, and the criteria of "Appropriate", and Gain value based on pre-test and post -test shows 65.21% of students have high gain criteria, 30.43% students have moderate gain criteria and 4.36% students have low gain criteria. Based on the results of this study, it is recommended for high school geography teachers to use and develop hydrological cycle learning media in an effort to increase student understanding more optimally.Keywords: Development, Learning Media, Understanding, Hydrological Cycle Materials
