In general, coastal areas have the physical and chemical properties of lessfertile 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 physicalproperties, need the addition of organic fertilizer. Source of compost canbe derived from a variety of wastes, including household waste and landfill.Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organic C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfill has an obstacle in the form of heavy metal containing high Cu and Pb. To prevent accumulation heavy metals into plant tissue or clean up heavy metals from the soil it was attempted by phytoremediation using jatropha plantation and bio-fertilizer that contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biological fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) Biofertilizers 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 absorption heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals

Authors: Boedoyo Mohamad Sidik 
Published: January 2019

As a developing country, currently the energy demand in Indonesia increases rapidly.Although Indonesia has a huge of oil reserves the production of oil fuels as the main energy consumption has not been enough and should be imported. It is devised to substitute oil fuel with other resources such as liquefied coal, natural gas, biofuels and dimethyl ether (DME). In the short future, the use of DME as an alternative fuel appears to be a promising approach for reducing the uses of diesel oil and LPG. It can be described in to two approaches. First, due to the high cetane number of DME, it can be used for compression ignition engines which have higher thermal efficiencies compared to spark ignition engines. Second, due to the physical properties of DME, it can substitute oil fuels and LPG uses in industries, commercials, and households for lighting and cooking. Hence, DME production is not limited to one feedstock. DME canbe derived from fossil fuel feedstocks, including natural gas and coal, as well as from renewable feedstock sources such as biomass. Since Indonesia have abundant of energy sources as DME raw material, such as natural gas, coal and biomass, utilization of DME into Indonesia energy system is necessary to be developed.Key words :Energy Potential, Dimethyl Ether, Diesel Oil and LPG Substitution
