This research was aimed to describe concrete mix design using British DOE and American AC/ methods viewedfrom concrete compressive strength and cost per-m, The mix design research used materials of sand and split from Krasak River, Nusantara brand Portland cement, and ground water from Faculty of Engineering UNY They were 10 samples each methods of (J 5 x15 x 15) em dimension. The data were collected by meant of experiment inthe Laboratory of Building Materials, Faculty of Engineering, UNY, andanalyzed descriptively. The results were that, to design concrete with K.225characteristic, the DOE method required mix composition of PC : sand:split  = I : 1,58:  3,49 with slump = 13 em, the average weight of concretecubes = 8,066 kgs and characteristic of compressive strength  =   263,1kg/em". The ACI method required mix composition of PC: sand: split = I:2,24:  3,12, with slump = tcm  (slightly over the design value), the averageweight of concrete cubes = 8,215 kgs, and characteristic of compressivestrength = 284,73 kg/em, Based on the cost analysis, per-cube, the DOEmethod cost was Rp 215.906,- and the ACI method cost was Rp 195.791,-..From the analysis, in general the AC/ method was more effective as well asefficient than DOE method.
