Abstract
The water content of soft clay soils and organic clay soils is very large, their weight is greater than the soil grains, so that when the soil is given a load, it will experience a problem of land subsidence which causes the pore water pressure to rise, exit and experience a decrease in consolidation. Therefore, it is necessary to conduct soil subsidence research in the laboratory using a test box and a bamboo concrete mat as a means of lowering the soil. The amount of land subsidence is detected by data acquisition. This research was conducted on a box-shaped test instrument measuring 80 x 90 x 100 cm3 . Soil is put into the box and soil subsidence test is carried out with a concrete slab using bamboo mats, after which a pressure of 0.2 kg/cm2 is applied; 0.3 kg/cm2 ; 0.4 kg/cm2 and 0.5 kg/cm2 . This test is carried out until it is no longer reduced. The results of the clay soil subsidence test using the test box modeling and bamboo concrete mats show that the soft clay soil is experiencing the reduction rate (Cv) is faster than organic clay soils. The amount of reduction (Cc) in soft clay soils is smaller than that of organic clay soils. Soft clay soils also experience volume changes (Mv) which are faster than organic clay soils. The compressibility (Av) of soft clay soils is also faster than organic clay soils. The amount of total soil subsidence in a period of 20 years in soft clay soils is smaller than in organic clay soils.
