Abstract
In North Toraja district, there are many roads built on soft soil which have low carrying capacity. To get a high bearing capacity of soil, it can be done by adding chemicals (chemical stability). One of them is the addition of coconut shell ash and lime which are often found in North Toraja. The purpose of this study was to determine the CBR value and the value bearing capacity of soil with the addition of coconut shell ash and lime which is used as a soft soil stabilizer. The method used in this research is the experimental method in laboratory. Soft soil samples were taken from Bori Village, Sesean District, North Toraja Regency, South Sulawesi. With the addition of a mixture of coconut shell ash 0%, 3%, 6%, and 9%, while for the lime mixture content of 2%. Based on the results of the study, it shows that soft soil stabilized with coconut shell ash and lime can increase the CBR value and soil bearing capacity. In soil without stabilized (native soil mixture), the CBR value was 6.47% and soil bearing capacity was 39.62%. For a mixture of 3% shell ash and 2% lime, the CBR value was 13.13% and the soil bearing capacity value was 49.21%. For a mixture of 6% shell ash and 2% lime, the CBR value was 31.32% and the soil bearing capacity value was 60%. For a mixture of 9% shell ash and 2% lime, the maximum value is 35.50% and the soil bearing capacity value is 61.45%
