Abstract
Research has been carried out related to the potential for landslides based on the value of peak ground acceleration (PGA) and slope in Sabrang Kidul Hamlet. This study aims to determine the value of the dominant frequency, amplification factor, PGA value, slope, and potential for landslides based on PGA value and slope. This study uses microtremor data obtained through direct measurements in the field. Microtremor data was taken at 24 points with a distance of 300 meters between points. The dominant frequency values and amplification factors were obtained through analysis using the Horizontal to Vertical Spectral Ratio (HVSR) method and the PGA values obtained through calculations using the Kanai method. The results showed that the dominant frequency value was in the range of 2.26 to 9.95 Hz, the value of the amplification factor was in the range of 1.96 to 23.98, and the Peak Ground Acceleration value was in the range of 15.31 to 31.86 gal. The potential for landslides in Sabrang Kidul Hamlet is divided into three zones, namely the low, medium, and high classification zones, where Sabrang Kidul Hamlet is dominated by the medium potential zone.
