Petroleum exploration and exploitation have caused significant environmental pollution, altering soil properties. This study evaluates the phytoremediation potential of Vetiveria zizanioides, Cynodon dactylon, and Oryza sativa L. in degrading Total Petroleum Hydrocarbons (TPH) in contaminated soils from the Minas Oil Field in Riau, Indonesia. Soil samples were prepared, homogenized, and analyzed for particle distribution, specific gravity, nitrogen, and phosphate levels. Over eight weeks, all three grasses demonstrated the ability to degrade PHCS, with V. zizanioides showing the highest degradation efficiency (89.9%), followed by O. sativa L. (85.0%), and Cynodon dactylon (75.4%). These results indicate the effectiveness of these grasses in phytoremediation, with V. zizanioides being the most efficient. This research highlights the potential of using specific grasses for sustainable remediation of petroleum-contaminated soils
