		abstract={Lathe machine is one of the production process machines used to form a cylindrical workpiece. Machining process will determine the surface roughness at a certain level, this research is done to know the value of the surface roughness of the workpiece. After the use of fertilizing using a variation of engine swivel speed 110 rpm, 200 rpm, 300 rpm, angle variation side cutting edge angle 12?, 13 ?, 15 ? and angle side rake angle 14?, 17?, 20? with low carbon steel St-37 diameter of 20 mm and length 100 mm. Based on the results of this study obtained the smallest value of surface roughness occurring in the sixth parameter with a spin speed of 200 rpm, angle side cutting edge angle 15 °, and angle side rake angle 14 ° measured surface roughness 2.40715 and the largest surface roughness occurs in the seventh parameter with a rotary speed of 200 rpm, the side cutting edge angle of 12 ° and the angle of the side rake angle 20 ° measured average surface roughness of 4.3394 ?m.}
