Abstract:
The Petroleum contaminated soil is one of the environment problem which can sharply decrease
the soil healthy. A friendly technology that can be used to overcome that problem is
Phytoremediation, is a method for removing pollutant by using Plant. In this research was using
Ramie (Boehmeria nivea.) as the Phytoremediator. For improving the Rami plant performance to
remove hydrocarbon Petroleum was applied Azotobacter sp. and Cow Manure. Azotobacter is
the Nitrogen Fixer bacteria that has a role to supply Nitrogen in the rhizophere system. This
experiment was focused on to determine the effect of Azotobacter sp. and cow manure (CM)
applying on rhizodegradation hydrocarbon petroleum in soil by using Ramie Plants. The
experiment was conducted in Green House scale, and the randomized block design was used.
The treatments were consist of four treatments (Control; Azotobacter sp; CM dose of 25 g/ 5 kg
Soil and CM inoculated by Azotobacter sp.). The results showed that the CM dose of 25 g/ 5 kg
soil treatment could significantly increase the population of Azotobacter spp. of 4.8 x 108 CFU/g
compared Azotobacter sp. treatment. Azotobacter sp. treatment showed tend to increase the
degradation of hydrocarbons rate and dry weight of ramie plants were 0.1047 -day and 40.433 g
respectively |
