In general, coastal areas have the physical and chemical properties of less
fertile land with an extreme dry climate, so that only a few plants that can live,
including Jatropha curcas L. To enhance fertility and improve soil physical
properties, need the addition of organic fertilizer. Source of compost can
be derived from a variety of wastes, including household waste and landfill.
Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organicÂ C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfillÂ has an obstacle in the form of heavy metal containing high Cu and Pb. To preventÂ accumulation heavy metals into plant tissue or clean up heavy metals from the soilÂ it was attempted by phytoremediation using jatropha plantation and bio-fertilizer thatÂ contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biologicalÂ fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) BiofertilizersÂ could inhibit the accumulation of copper (Cu) and lead (Pb) into Jatropha curcas L., (3)Jatropha plant can be classified as phytoremediation plants, because it can absorptionÂ heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals
