Abstract:

 
Pollution of petroleum waste causes a decrease in soil productivity. Hydrocarbon spills on the soil cause disruption to the surrounding ecosystems, including humans. This problem continues to emerge because Indonesia is a large-scale oil-producing country accompanied by a high waste of petroleum. The amount of land contaminated with oil due to the oil production process increases thousands of tons every year. Oil spills can reduce the stability of the soil and the degradation of soil functions that cause critical land. The technique of restoring contaminated land with phytoremediation can be used as an alternative to land restoration using plants to immobilize pollutants, absorb and transform into tissue cells. Plant groups such as grass have substantial potential compared to other plants because it has a lot of roots, strong roots system and spread in the soil. Phytoremediation applications need to pay attention to biological remediation requirements made by the government. This technology requires coordination between stakeholders so that the use of phytoremediation is more optimal. The purpose of this study is to examine the potential of grasses to restore oil-polluted soils as part of land sustainability. Phytoremediation technology can be applied to remove contaminants from polluted soils with low cost, effective and safe for the environment.
