Peat soil is a type of organic soil formed from the incompletely decomposed remains of plants. Due to its unique properties, such as low bearing capacity and high water content, peat soil often experiences significant and long-term subsidence. Stone columns are a ground improvement method that involves replacing a portion of the original soil volume with compacted stone material, forming columns that enhance soil stability. This research was conducted on group columns using a stone column method mixed with cement. The group columns consisted of four piles with a uniform length of 30.00 cm. In this study, the spacing between columns was varied with a spacing-to-diameter ratio (s/d) greater than 2.50, namely 11 cm, 12 cm, and 13 cm, using columns with a diameter of 4.20 cm. In addition, variations in diameter were also made at 4.20 cm, 4.80 cm, and 6.00 cm with s/d equal to 2.50. The loading tests were performed to determine the ultimate bearing capacity of the soil after reinforcement. The test results showed that the soil bearing capacity increased after reinforcement with the increasing diameter of the group cement stone columns and decreased with the increasing spacing between the group cement stone columns. The highest ultimate bearing capacity was obtained at a diameter of 6.00 cm, at 21.855 kPa (Tangent Intersection method) and 29.918 kPa (Mazurkiewicz method). In addition, the BCR values obtained were 4.711 (Tangent Intersection method) and 3.682 (Mazurkiewicz method), with corresponding increases in BCR of 371.12% and 268.19%, respectively.
