Abstract
Objectives: To enhance the compaction properties of peat soil, such as shear strength, compressibility, permeability and consistency limit. Methods/Analysis: One of the known techniques is by using Electrokinetic Stabilization to enhance the strengthening properties of peat soil. In this method, aluminum used as electrodes with the voltage potential of 110 V was applied on both cathode and anode electrode at the operational period of 3 hours with an applied load of 50 kg. Findings: Some parameters of soil, like shear strength (τ), moisture content (WN), liquid limit (WL ) and compaction have been observed. Results have shown that the magnitude of shear strength at Parit Raja Haji Ali has improved from 8.8 kPa to 74 kPa and MC was decreased from 568.247% to 309.273%, WL was increased from 136.107% to 191.225%. Application: The experimental results suggest the potential of developing electro kinetic treatment technique to stabilize the physical properties of peat is effectively and efficiently.

Highlights
Peat soil has considered as having more than 75% organic content with the low shear strength of 5 to 20 kPa1, with a high moisture content of (250% to 985.40%)[2] and high compressibility, which often result in difficulties when construction work is undertaken on the deposit
The results show that shear strength was improved up to 74 kPa for Parit Haji Ali while it was increased up to 68 kPa for Parit Nipah peat soil
The following conclusions were drawn after performing Electrokinetic Stabilization (EKS) treatment on peat soil of the Parit Botak area
Summary
Peat soil has considered as having more than 75% organic content with the low shear strength of 5 to 20 kPa1, with a high moisture content of (250% to 985.40%)[2] and high compressibility, which often result in difficulties when construction work is undertaken on the deposit. Malaysia is 6th country in the world with the highest amount of total peat soil[4]. Peat soil is considered as one of the most challenging soil for the construction projects due to its poor characteristics such as low shear strength, high water content
