Summary: Peat soil is well known as problematic soil because of its poor geotechnical properties such as high water content, low shear strength, high organic matter, low bearing capacity and high compressibility. These properties make the soil as one of the most difficult soils to deal with for peat soil causes excessive settlement under constant load. Due to these geotechnical issues of the peat soil, improvement of the soil is essential in order to enhance its engineering properties so that the soil can act as soil foundation. In this research, Effective Microorganism (EM) is used as the soil stabilizer in order to investigate the optimum mix proportion of EM as the stabilizing agent on peat soil. The objective of this research is to determine the strength effects of 1%, 5%, 10%, 15% and 20% of EM concentration with a constant optimum moisture content which is 43.5%. Basic soil tests such as moisture content, specific gravity, plastic limit, liquid limit and compaction test together with a series of unconfined compression tests were conducted on the peat soil mixtures.
