Contribution of bearing capacity of land based on engineering geology in regional spatial policy (A study in Semarang City)

Abstract

The bearing capacity of the land (BCL) is a determining factor for the bearing capacity of the environment. The BCL depends on the resources in the land space, which is called the supply capacity. The capacity of providing BCL for spatial use is determined by the stability of the landmass of the expanse of land, namely engineering geology characteristics. The BCL for the use of space has been based on the land capacity for agriculture and the physical land. There are important things that are not included in the criteria, namely the ability of the land in terms of engineering geology characteristics. Soil samples from the drill were analyzed for soil characteristics. Analysis of field and laboratory tests to get the distribution of the value of BCL, then compiled the map of the BCL of Semarang City at 2.5-5.0 m depth. The BCL value is 0.201–14.248 kg/cm2, settlement value is 0–247.728 cm, duration of decline (DOD) is 0 – 5.147 years. The paper intended to contribute to spatial planning policy thinking, related to the BCL based on engineering geology as a determinant of land capability, an evaluation instrument of space utilization, and fundamental policy formulation.
