Research in the tourism area at Batu Kuda Bandung has been carried out using Interpretation Conventional Reciprocal Method (CRM) refraction data which aims to produce a seismic refraction data processing GUI using the Matlab programming language, so that it can know the wave velocity value and get 2D cross section. Data obtained in the form of wave propagation time as forward and reverse time, from the travel time of the wave and distance and time geophone analysis. From the results of the interpretation of the data obtained the velocity of P wave propagation in the medium and depth in 2 layers. In the first layer obtained a velocity value of 628.98 m / s with the depth of the first layer ranged from 0 m - 8.73 m, and the seismic wave velocity in the second layer was 1228.99 m / s with the depth of the second layer ranged from 8.73 m - 20 m. Based on the 2D model the distribution pattern of velocity values, it can be indicated that the first layer is the latosol soil layer containing sand, gravel, fine sediment and clay. And in the second layer contains fine deposits, sandstone, gravel, sand, fine sand (silt), clay and clay. These materials as a result of the process of the eruption of an undefined young volcano.
