Abstract: The purpose of this study was to determine the extent to which an increase in physical properties, index properties and mechanical indexes of sedimentary material due to the addition of cement (cement stabilization). Materials used are materials sediments of the River Jeneberang (Bili-Bili Dam approximately) due to the occurrence of avalanches of Mount Bawakaraeng. Methods of testing carried out is testing laboratory using ASTM and AASHTO standard analysis, a mixture of cement used is portland cement with a variety of different percentages of cement mix. The results showed that soil sediment including silt in the soil from 95.93-96.47%, from 0.97-1.31% clay and sand soil from 2.56-3.69%. Index properties with 91.805% water content, specific gravity value of 2.477, plasticity index 16.85-17.56% by dry weight content of 0.777 t/m3, the unconfined strengths comressive 0.11 kg/cm2 (2.5% of cement) and 7.84 kg/cm2 (20% cement) to the age of 3 days and 0.592 kg/cm2 (2.5% of cement) and 16.66 kg/cm2 (20% cement) for 28 days, tends to increase linearly with the addition of cement volume. While, the speciemen density obtained in the range 1.544 g/cm3 (2.5% of cement) and 1.643 g/cm3 (20% cement) to the age of 3 days and 0.592 kg/cm2 (2.5% of cement) and 16.66 kg/cm2 (20% cement) for 28 days. It seems to be slightly increased by the addition of cement volume. Based on the results of this study is that with the change of physical properties and mechanical properties of the sediment material will enhance the ability of the soil as an alternative material that meets the technical requirements for building materials.
