The aim of this study was to obtain the stabilized peat soils using the Effective Microorganisms (EM). The volume of EM added and mixed with peat soils varied with 2, 4, 6, 8 and 10 and then were cured for 7, 14 and 21 days. The experiment was done for uncontrolled and controlled moisture content. Prior conducting the main experiments, the physical properties such as moisture content, liquid limit, specific gravity, and plastic limit etc. were measure for raw peat samples. The Unconfined Compressive Strength (UCS) test was performed followed by regression analysis to check the effect of EM on the soil strength. Obtained results have shown that the mix design for controlled moisture contents showed the promising improvement in their compressive strength. The peat soil samples with 10 of EM shows the highest increment in UCS value and the percentage of increments are in the range of 44 to 65 after curing for 21 days. The regression analysis of the EM with the soil compressive strength showed that in controlled moisture conditions, EM significantly improved the soil stability as the value of R2 ranged between 0.97 - 0.78. The results have indicated that the addition of EM in peat soils provides significant improving in the strength of the soil as well as the other engineering properties. © 2018 Published under licence by IOP Publishing Ltd. date: 2018 publisher: Institute of Physics Publishing official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85046081966&doi=10.1088%2f1755-1315%2f140%2f1%2f012088&partnerID=40&md5=c293023ae17425e25cb3d7db1db82f9b id_number: 10.1088/1755-1315/140/1/012088 full_text_status: none publication: IOP Conference Series: Earth and Environmental Science volume: 140 number: 1 refereed: TRUE issn: 17551307 citation: Yusof, N.Z. and Samsuddin, N.S. and Hanif, M.F. and Syed Osman, S.B.
