This paper focuses on the potential utilization of volcanic ash and coarse volcanic slag for no-
fine concrete for drainage structure of Prambanan temple yard. This material produced from volcanic
eruption also becomes environmental important issues as waste material if it is not effectively reduced or
reused. Coarse volcanic slag is commonly known by local people as Bantak. The experimental study was
conducted to determine engineering properties of no-fines concrete materials and discharge capacity of
drainage system was calculated to identify the optimal dimensions of the drainage channel. In addition, a
numerical analysis was carried out using SAP2000 and Plaxis to control structure stability. Based on
numerical and experimental study, the utilization of no-fine concrete from volcanic ash and bantak by using
certain mix design can be used as a porous drainage structure. By utilizing the eco-friendly material as
structural material, the originality of the building will not be disturbed.
