Stabilisasi Tanah Gambut Menggunakan Microbially Induced Calcite Precipitation Dengan Variasi Larutan Sementasi

---

The development of construction needs to pay attention to the condition of the subgrade so that it can carry the load above it. Peat soil is known to have high moisture content, organic content and pore number. Therefore, it needs to be stabilized before being used as a subgrade. Microbial-induced calcium carbonate (CaCO3) precipitation is an environmentally friendly soil improvement that can cement soil particle contacts and increase soil strength through bacterial metabolism. This study aims to assess the strength of stabilized peat soil using Bacillus subtilis bacteria in the MICP method with variations in cementation solution at 7, 28 and 56 days of curing through UCS testing. The cementation solution variations used were 5%, 10% and 15% of the peat soil by weight. The highest compressive strength was found in the 15% variation at 56 days with a compressive strength of 23.2 kPa and a dry density of 3,7 kN/m3. The amount of cementation solution affects the compressive strength of soil stabilized using microbes. The higher the density of the test specimen, the higher the compressive strength of the soil.
