The research using the method of refraction microtremor (REMI) has been carried out in the village of Salua, District of Kulawi. Seismic method of refraction microtremor (REMI) is an effective and efficient method for determining the shear wave velocity (shear wave) each bedding soil. The purpose of this study was to determine the subsurface structure based on the propagation speed of shear waves and to estimate the elasticity characteristics of the subsurface rocks. Data processing is divided into two phases. The first stage is done by using two programs that use the Surface Wave Analysis Wizard program and WaveEq (Surface Wave Analysis) program. The second stage determines the shear modulus of rock. From the data processing of the 6 lines can be seen that the subsurface structure is dominated by dry sand with shear wave velocity range of 80 m/s with a shear modulus range of 10,24-70,56 N/m2 and by soil with shear wave velocity in the range of 120 m/s with a shear modulus from 38,16-108 N/m2, and also by clay with shear wave velocity in the range of 405 m/s with a shear modulus 377,25 N/m2.
