lahan yang dilakukan diperoleh kedalaman maksimal sampai 27 meter. berdasarkan nilai kecepatan gelombang geser (vs) yang didapat dan dihubungkan dengan sni 1726-2012 tentang pengelompokan jenis tanah dan batuan, daerah penelitian dikelompokan ke dalam tanah lunak (se) dan tanah sedang (sd). untuk lintasan 1 diperoleh dua lapisan tanah yaitu lapisan tanah lunak (se) dengan nilai kecepatan gelombang geser (vs) 157 – 174 m/s dan lapisan tanah sedang (sd) dengan nilai kecepatan gelombang geser (vs) 175-182 m/s. pada lintasan 2 hanya di dapatkan lapisan tanah lunak (se) dengan nilai kecepatan gelombang geser (vs) 125-145 m/s. untuk lintasan 3 didapatkan lapisan tanah lunak (se) dan tanah sedang (sd) dengan nilai kecepatan gelombang geser (vs) 146-173 m/s dan 179–195 m/s. sedangkan untuk lintasan 4 dan 5 diperoleh lapisan tanah lunak (se) dengan masing-masing nilai kecepatan gelombang geser (vs) 142-160 m/s dan 90-110 m/s. kata kunci : gelombang rayleigh, kecepatan gelombang geser (vs), seismik masw, profil 2d, seisimager, klasifikasi tanah ? abstract the research about the investigation of subsurface characteristics using rayleigh wave has been conducted in meuraxa district, banda aceh. this research is important because banda aceh is an area which is dominated by alluvial deposits and being included to area which is experiencing large infrastructure developments. the research aimed to find out the type of subsurface layers which is related to the planning of geotechnical infrastructure developments. the data was found based on shear wave velocity value (vs). the acquisition were conducted by seismic masw(multichannel analysis of surface wave)method using seismograph pasi which is done at five lines with every lines has space between geophones is 1.5 meter and total of line lenght is 54.5 meters. the data obtained from acquisition seismic masw (multichannel analysis of surface wave) method are wavelet signals in time domain which is processing by seisimager software. based on the analysis, the maximum depth was found up to 27 meters. based on shear wave velocity value (vs) which found and related with sni 1726-2012 regarding the classification soil and rock, the areas in the research are classified into soft soil (se) and medium soil (sd). for line 1, there were two soil layers which are soft soil (se) with the shear wave velocity value (vs) of 157 - 174 m / s and medium soil (sd) with the shear wave velocity (vs) of 175-182 m/s. for line 2, there was only the soft soil (se) with the shear wave velocity value (vs) of 125-145 m/s. for line 3, there were soft soil (se) with the shear wave velocity value (vs) of 146-173 m/s and medium soil (sd) with the shear wave velocity value (vs) of 179-195 m/s. as for line 4 and line 5, there was soil layer (se) with the shear wave velocity value (vs) of 142-160 m/s for line 4 and 90-110 m/s for line 5. keywords: rayleigh wave, shear wave velocity (vs), seismic masw, 2d profile, seisimager, soil
