This study aims to analyze the impact of soil compaction using a vibro roller on the potential for cracking in building structures around the work area. This study uses a quantitative approach through finite element-based numerical simulations using Plaxis 2D software to model the settlement and distribution of soil pressure due to vibration. The simulation results show that at a distance of 0.5 meters from the building, there is a settlement of 2.2 cm with a soil pressure of 153.2 kN/m²; at a distance of 5 meters, a settlement of 0.97 cm (140.6 kN/m²); a distance of 10 meters, 0.32 cm (137.0 kN/m²); and a distance of 15 meters, 0.29 cm (135.5 kN/m²). Technically, the settlement value at a distance of 0.5 meters is still below the tolerance limit of SNI 8460:2017 of 2.5 cm, but the increase in soil pressure indicates a potential risk to certain structures with sensitive foundation conditions. This research contributes to providing a safe operational limit for vibration compaction in dense construction areas, with a recommended minimum distance of 5 meters to reduce the impact of deformation and maintain the safety of surrounding structures.
