Estimasi kecepatan gelombang geser dan karakterisasi tanah di Universitas Islam Indonesia menggunakan metode multichannel analysis of surface wave

Indonesia lies in a highly seismic region, making soil characterization essential, particularly at the Islamic University of Indonesia (UII), which is located near the Opak Fault. The geological variability across the campus requires an evaluation of dynamic soil properties such as shear wave velocity (Vs) to better understand site response during seismic loading. This study aims to estimate Vs30 values, identify soil characteristics, compare MASW‐derived values with USGS data, and assess liquefaction potential and microzonation within UII. Field measurements were conducted at 12 survey points using the Multichannel Analysis of Surface Waves (MASW) method. The collected seismic data were processed using Geopsy, Dinver, and QGIS to produce shear wave velocity profiles and spatial zonation maps. The results indicate that soil classification across UII is predominantly SC–SD. The highest Vs30 value was identified at the Faculty of Psychology and Cultural Studies, reaching approximately 363.6 m/s, while the lowest Vs30 value occurred at the Faculty of Medicine Laboratory with approximately 218.8 m/s. Liquefaction susceptibility ranges from moderate to high, influenced by local subsurface variability. The resulting microzonation map provides essential spatial information for earthquake‐resistant infrastructure planning on the campus.
