Waste ash (fly ash and bottom ash) is the main waste in the operation of steam power plants, especially those that use coal fuel. Research on the use of this waste has been done a lot, as well as the use of this waste to make other products (brick, light brick, paving, mortar). But until now, each PLTU has not yet integrated to utilize this ash waste to its full potential. This paper aims to provide a selection method in optimizing and selecting alternative uses of ash (fly ash and bottom ash) so that it has a benefit value by examining waste utilization in detail in terms of production aspects, environmental aspects and economic aspects. The method used in selecting the utilization of ash waste as building substitution material is carried out gradually in terms of technical, production, economic and market aspects.
