Abstract

There are many method of Soil Improvement to increase the soil bearing capacity to support the building which is exist on those soil. The recent method is Bio-Enzyme Treated Soil with bio-organic material based. The sampling soil used is original soil and bio-enzyme treated soil, with variation of concentration between 1% up to 3% and curing time 7 days and 28 days. The Laboratory test consist of California Bearing Ratio Test, Unconfined Compression Strength Test, and Direct Shear Test. The research of Laboratory Test was founded that soil sample has moisture content = 73.45%, specific gravity = 2.4 gr/cm 3 , Liquid Limit = 88.04 % and Plasticity Index is 51.50. The original soil sample is wet clay category. Refer to the physical behavior test for bio-enzyme treated soil, was founded that PI value will decrease, CBR shown increase compared to the original soil. Significantly increasing has been occurred on the original soil which is treated with Bio-Enzyme 1% on CBR value for 0,1” penetration reached 8.43%, for 0.2” penetration reached 6.47% on curing time 28 days, compared with Bio-Enzyme Treated Soil 3% which is only reached CBR 6% on 0.1”penetration , and 4,84% on 0.2” penetration. From the unconfined compressive test result shown a decreasing of unconfined compressive test for the original soil. The Direct Shear Test for Bio-Enzyme Treated Soil shown increase compared with original soil. Meanwhile, with the increase of CBR means the Bio-Enzyme Treated Soil has been increased too.
