Abstract

Basically, clay soils have high plasticity properties, relatively high shrinkage swelling
power, and low bearing capacity or soil strength. If a civil engineering structure is built
on clay soil, there will be problems with the soil itself, namely settlement and sliding. To
overcome the bad clay soil, it is necessary to improve the soil. Soil improvement can be
done in two ways, namely: mechanical method and chemical method. The method of
improving clay soil by chemical means is using lime and bagasse ash. Stabilization with
lime can increase the UCS value of the soil and the increase is quite significant. The use
of bagasse ash was chosen as a stabilizing agent because it has loose properties so that it
can be a filler and reduce the cohesion of the clay. Testing on the swelling potential value
and soil bearing capacity (UCS Test) It was carried out by mixing clay and lime and
bagasse ash with mixed variations, 0%, 8% (4%aat + 4% lime), 16% (8% aat + 8% lime),
24 (12% aat + 12% lime) and ripened for: 7, 14, 21, and 28 days. In the swelling test, the
optimum value for a mixture of 24% curing 28 days was IP = 9.8%, including the
category of low swelling. While the results of the UCS test got the optimum value in a
mixture of 24% curing 28 days of qu = 1.240 kg/cm² including stiff clay/stiff. From this
research, it can be concluded that the greater the percentage of lime and bagasse ash
mixture that is added, the harder the soil becomes.
