Utilization of Plastic Waste as Soil Stabilization Material and Their Effect on Unconfined Compressive Strength Values

The objective of this research was to improve the bearing capacity soil located on Kampung Juhut Street, Pandeglang Regency, which initially had a 3.01%, through stabilization methods. plastic powder selected as an additive due its non-cohesive characteristics, counterbalance cohesive nature clay soil. study aimed identify type and classification, evaluate impact physical properties, examine changes in unconfined compressive strength after incorporating proportions 2%, 4%, 6%, 8%, 10%, with curing durations ranging from 0 28 days. results indicated that belonged category organic soils moderate high plasticity according USCS classification system. index decreased 22.9% 12.2% at 8% variation 11.9% 10% variation. initial 1.1 kg/cm2. greatest improvement observed variation, resulting value 3.4 kg/cm2, indicating highly rigid consistency.
