Decreasing Of Lead And Cadmium By Cladosporium and Albizia (Paraserianthes falcataria L. Nielsen) Mycorrhizal On Oil Sludge Phytoremediation

Oil sludge as we know is one of hazardous petroleum waste that make a particular concern in the environment. Beside of Polyaromatic Hydrocarbon (PAH) oil sludge consist of several heavy metals such as lead and cadmium that can inhibit growth and development of plants and other organism. Cladosporium is one of fungi genera isolated from Tanjunguban oil sludge and known can produce bio-surfactants and tolerant in heavy metal stress. The treatment used is a combination of Cladosporium and Albiziamycorrhizal in two oil sludge concentration which is 30% and 35%. This study carried out for 60 days and contain of two steps. The first step is composting process by Cladosporium during 30 days and continued by Albizia for the phytoremediation process during 30 days. Parameters measured consist of content of lead and cadmium after 60 days treatment analyzed with Atomic Absorption Spectrophotometry (AAS) method and colonization of AMF in Albizia root. The results showed that both of lead and cadmium have a bigger decrease at 35% oil sludge concentration. Cladosporium can decrease lead content at 17.94% and cadmium content until 32.22% after 60 days treatment. On the comparative, colonization of AMF in Albizia root reached 100% in all treatment along the decrease of lead and cadmium.
