Stirling machine has the advantage that it can utilize all kind of fuel, so that it is suitable for biomass utilization. In this study the analysis of best design of stirling machine different from previous study was carried out, which is design innovation on alpha type stirling machine by making phase angle become 180°, with the aims of lowering the gravitational force when cool cylinder is compressed, because the existing phase angle used is (90°) has the disadvantage of cool cylinder which is perpendicular, so that the compression is against gravitational force. The designing method was conducted by using Quality Function Deployment. The result of this study was to obtain the best variance of shape and machine stirling design dimension, which is variance 5, biomass stove- pulley and belt- was directly used. Variance 5 is chosen because it was the most suitable with the designed specification. Biomass stove is chosen as heat source, because the fuel used is classified as alternative fuel. Pulley and belt were chosen as mechanism of work transmission, because it has less noise compare to sprocket and chain. Its output work was directly chosen because its construction is simpler and the energy used is more optimal.
