Abstract
The study area is located in the area Sidomulyo, Pengasih Distric, Kulon Progo, Yogyakarta. The geograpic area located on the coordinates 110 ° 6 '43' '- 110 ° 9' 23 '' east longitude and 7 ° 42 '34' '- 7 ° 45' 16 '' shouth latitude. Size study area has a 5 x 5 km. In the landslide area has high intensity of rainfall. Therefore, researchers want to know linkages between slope stability rate of air infiltration of rain. Methods used namely with using methods of quantitative descriptive research data. This is collected and declared with number’s of test results in the field and analysis of the safety factor with using model infiltration Green-Ampt (Lumb, 1962; Pradel and Raad, 1993; cho and Lee, 2002 ;. Xie et al, 2004). Result of findings linking the rate of infiltration with values values obtained FS. All rate of slopes ranged from 0.330 until 0.636. When drycondition 0,3 and indry condition 0.55. Therefore, these observations, overall slope not impaired FK due to the infiltration of rain. Researchers found on the slopes of 1 and 4 did not decline FK because all of them has not reached the maximum density on maximum water content. Result of the reaserchfindings conclode that located area also found unstable slope
