Summary:The production of electricity from burning of coal produced large amount of fly ash waste. Fly ash is potential to be used as a soil ameliorant material because it has a very fine size. The purpose of the study was to to develop a new alternative organic fertilizer and to find out the contents of micronutrients and heavy metals in organic fertilizer made from fly ash and organic waste. The study was conducted by composting several organic matterials that consisted of fly ash, poultry manure, peanut stover, sawdust and banana stalk in different compositions. The selection of good organic fertilizer was conducted based on the ranking method. The results showed that the selected organic fertilizer was fertilizer that contained 10% of fly ash. The micronutrient (Cu, Mn and Zn) contents of the organic fertilizers were low, but the Fe content was high. The heavy metal (As, Cd, Hg and Pb) contents of the fertilizer were low.
