“…The location of the strike (shot) points were arranged in such a way that they lay along the seismic profile line (Table 4). Figure 3 Seismic refraction layout and hammering technique for P-and S-wave [42,43] The data (P-and S-waves) collected and saved in the seismograph were transferred into a computer for processing and interpretations following the flow chart shown in Figure 4 using several software (IXRefract, Microsoft Excel, SeisOpt@2D v6.0 and Surfer 8). The direct current (DC) effect in the data was removed for better signal to noise ratio (S/N) quality.…”

This study was conducted in Banda Aceh district by utilizing seismic refraction P- and S-waves methods on three similar profile lines, with the aim to identify subsurface characteristic. The seismic data were acquired using ABEM TERRALOC MK8 system with 28 Hz vertical and 6 Hz horizontal geophones, and suitable seismic sources. Software used for processing to produce 2-D tomography sections and interpretations are IXRefract, Microsoft Excel, SeisOpt@2D v6.0 and Surfer 8. The results show the study area comprises of four subsurface layers with strong to very strong relation between Vp and Vs (R2 is >0.7509) for each layer. Ratio value of Vp and Vs (Vp/Vs) for each layer (1st to 4th) was calculated to be 4.75 – 5.79; 6.50 – 8.89; 6.57 – 12.17 and 6.08 – 8.21 respectively. This study concluded that the ground subsurface in Banda Aceh district is made up of water saturated unconsolidated sediments that was identified to be a mixture of clay and silt at depth up to 55 m.

“…Generally, the waves used are P and S waves generated by a seismic source, i.e., a sledgehammer, weight drop, air gun, etc. (Sabrian et al, 2018). The description of the subsurface model presented by this method is plotted based on the time and distance of the wave travel, where the wave speed can be calculated to distinguish the types of layers below the surface.…”

A good strength level of the ground surface is the main concern in an area with rapid housing infrastructure development, such as Baitussalam district-Aceh Besar, Indonesia. A seismic refraction method was applied with three similar profile lines using PASI 16S – 24P equipment and 10 Hz vertical geophones to identify the sub-surface layer. The result was processed using Winsism software and Surfer 8. The results of seismic refraction were deduced and correlated with conventional geotechnical investigation obtained by a previous study. The results of 3 survey lines show that the area has two main layers. The first layer was interpreted as overburden (soil and clayey sand) with a compressional wave velocity (Vp) value of fewer than 1.8 km/s. The second layer produces a high velocity of more than 2 km/s. This second layer is interpreted as highly to moderately weathered rock. The results of seismic refraction surveys of the present study suggest a reasonably good correlation with the standard penetration test (SPT) and rock quality designation (RQD) obtained in the previous investigation. The strength level of the second layer showed N-SPT of 65 and RQD of at least 50%.
