As time goes by, people are racing to develop technologies in order to help solving problems, such as building the industries and all of its machines. However the industrial itself has several drawbacks such as the industrial waste. Sludge soil that contaminated by heavy metal is one of the examples of industrial waste. Heavy metals have a negative effect on human’s health, such as mental disorder. Exploration, transportation, and exploitation of crude oil can cause marine and terrestrial oil pollution. Oil spill is harmfull for marine environment. Lead (Pb) and Cadmium (Cd) in gasoline are the examples of heavy metal that are usually contained in gasoline and it can be stick and make soil is contaminant. Thus, the industrial waste needs a…show more content…
The plant that usually used as mediator is Amarath plant (Amaranthus spinosus)(Terry, N., Banuelos, 2010). Basically, every plant can adsorb the pollutans to the roots and extract contaminant from soil or water and concentrate them in their tissue, and then degrade pollutants by biotic and abiotic process. The Phytoremediation plant is mainly used for extracting heavy metals and organic contaminant from soil,such as Amaran. There are three categories of plants that can grow in contaminated area: Tolerant, indicator, and hyper accumulator. Amarant has a hyper accumulator that capable to uptake high concentration of contaminant without damaging its growth. (Khoramnejadian, S.,2014). The mechanism involved in phytoremediation is plant could take up heavy metal, solvent, aromatic carbon, and other contaminants from soil, sludge and water. However phytoremediation is not suitable for high contaminated sites, limited to the surface area. the purpose of this study is to evaluate the precise concentration of Amaranth in order to give the best result in degrading the polutant level in soil that contaminate…show more content…
On the control plant which does not have contaminated soil, has pH buffer and higher alkalinity because the amount of lime is higher than the other (Khoramnejadian, S.,2014). Next, for sample 2, which has comparison 1:2 between soil and contaminated soil, has higher electrical conductor and organic compound, because by increasing the petroleum hydrocarbon in the samples, the organic compound become increased, because organic compound in the plants has direct relation with total nitrogen , if the total of nitrogen is increasing, the amount of organic compound is increased. Heavy metals and organic compound in the plant can affect the soil acidity (Khoramnejadian,
