Soil is a support for a building that functions as a support for the construction load on it. There are several types of soil that have properties that are not suitable for constructing a construction, namely those that have low bearing capacity, low shear strength, and large soil swells. The research that the author is carrying out here is a research on the Juanda Sidoarjo Frontage Road Development Project along the 200 m length, mostly passing through a location that is in subgrade conditions in the form of soft clay soil up to 30 m. At that location, the frontage road is planned to use the road embankment. The use of road embankments on soft soil is predicted to cause problems with the stability of the bearing capacity of the subgrade and subgrade subsidence. On the other hand, the cost of road foundation construction needs to be reduced to make it more economical. In collecting the required data, the authors use interview techniques. While in the discussion used qualitative and quantitative research methods. From the results of the analysis conducted by the author on the finite element analysis method, the SF (safety factor) value using soil reinforcement with bamboo cerucuk mats is 2.0734 (meets the minimum requirements). Where (SNI 8460-2017) requires a minimum SF (safety factor) value with an additional load of SF > 1.5. So the strengthening of the bearing capacity of the soil using a bamboo cone mat is very influential on the strengthening of the carrying capacity of the soil.
