Applying long term vinasse without pre-treatment to soil causes eutrophication to water and soil. The paper aims to process vinasse of the alcohol industry as an effective growing medium of environmental-friendly microorganisms that can be used in the organic fertiliser manufacture. The effective microorganism has some benefits such as becoming a soil enhancer when applied directly to the soil or an accelerator in the maturation of the organic fertiliser. This research starts with the chemical content characterisation of vinasse and the addition of microorganisms nutrients. After the media is ready, the EM inoculum is added and the breeding result is used for the manufacture of organic fertiliser based on goat farm waste. The EM culture analysis reveals an increase of the microbial number. Moreover, the organic fertiliser obtained has a content of an organic matter, nitrogen, phosphate, and potassium referring to 43.42 %, 3.05 %, 0.40 % and 1.23 %, respectively. It is in accordance with the Indonesian government regulation. © 2019 Journal of Chemical Technology and Metallurgy.
