In the landfill, lining systems play an essential function in providing a barrier between the waste and the environment. Soil liners are used in the liner system to reduce leachate infiltration and prevent ground pollution. It is essential to compact the layer properly to achieve low hydraulic conductivity of 1x 10-9 m/s. The purpose of this study is to investigate the optimum content of geopolymer mixed in laterite soil in designing a modified soil liner. Geopolymer binder consists of palm oil boiler ash as source material and sodium hydroxide mixed with sodium silicate as an alkaline solution. Laboratory work involved physical properties test and compaction characteristics of the modified mixture. The percentage of geopolymer in the mix varies between 0, 10, 15, and 20% of lateritic soil dry weight. The results obtained imply that the laterites soil mixed with geopolymer gives a plasticity index ranging from 10 to 19%, with specific gravity ranging from 2.43 to 2.62; the maximum dry density (MDD) varies from 1.71 Mg/m3 to 2.19Mg/m3, and the optimum moisture content (OMC) ranges from 13.58% to 16.38%. The conclusion reached based on compaction characteristics is compacted geopolymers are compatible with lateritic soils. Soil strength of laterite with 15% of geopolymer mixture is the best mix design to be used as a modified soil liner in a landfill. From the result, geopolymer could be the alternative material in enhancing the soil liner properties.
