South Sumatra Province has a pest area of 1.4 million Ha. The distribution of peat soil in Ogan Hir is 23,687.91 Ha. Pent soil has a low bearing capacity. This research aims to explain the effect of stabilization on peat soil characteristics. Peat soll samples were taken using the Block Sampling method. The research locations are Parit Village and Lorok Village, Ogan Ilir Regency. Peat soil has poor properties to be used as foundation soil for civil construction. To overcome this, ane method of soil improvement is needed, namely the chemical stabilization method: changing the chemical properties of the soil by adding a mixture. The mixture used is palm shell ash waste with variations of 5%, 10%, 15%, 20%, 25%. To determine the effect of this mixture, soil properties (physical and chemical), SEM, EDS, PTS and CBR tests were carried out. Soil properties test results: water content (m) in Parit Village 220.29%, and Lorok Village 252.39%. The fiber content (FC) test results for Parit Village were 25.17% and Lorok Village 28.01%. Peat soil is classified as fibrous peat soil. The CBR value for Parit Village was 4.60% and Lorok Village was 4.16%. The results of the immersion CBR test, Parit Village had a curing period of 7 days, a variation of 5%, namely 4.68%. Lorok Village obtained the greatest results, namely a curing period of 14 days, a variation of 25%, namely 4.76%. The CBR value obtained in this study is in the range of 3%- 5% (normal) when used for subgrade strength with compaction conditions depending on the road category.
