Soil is the most important component in construction field, because soil supports construction buildings. The problem is, almost 65% soil in Indonesia is expansive soil that has large swelling and shrinking potential. This problem made worse by the tropical climate. Expansive soils easily shrink in dry season and swell in rainy season. Not only those problems, waste is also major problem in Indonesia. In order to prevent these two problems, a research was conducted by using organic waste as expansive soil stabilization material. Organic wastes that use in this research includes sugarcane bagasse, used tea leaves, rice husk ash, eggshell, and palm fiber. These five organic wastes will be combined with South Jakarta, Cikupa, Bekasi 1, Cikarang, and Bekasi 2 soil sample. All of these samples will be tested with penetrometer and free swell test. Based on the results, organic waste that most affected the increase of q u up to 69.56% and decrease of FSI up to 80.00% of South Jakarta, Bekasi 1, and Bekasi 2 samples is rice husk ash. Whereas organic waste that most affected the increase of q u up to 98.67% and decrease of FSI up to 53.41% of Cikupa and Cikarang samples is Sugarcane bagasse.
