Plasma Arc Machining is a new machine that has been owned by the Industrial Engineering Laboratory of UIN Sunan Kalijaga since July 2022. Problems that occur with Plasma Arc Machining is the result of cutting causes lumps or burr which is quite large due to heat plasma so that there is surface roughness on the workpiece. This research uses a design of experiment method with full factorial design which aim to minimize the surface roughness of the stainless steel plate. In this research there are three factors, that is height torch, cutting speed, and electric current by three level so that obtain 33=27 trials required. The results of the research on data processing analysis of variance show that the most influential factor on surface roughness is cutting speed with contribution value of 90.76% followed by two other factors, that is height torch with contribution value of 2.42% and electric current with contribution value of 0.23% and contribution value of noise by 6.59%. Then based on data processing robust design the optimum combination of parameters is obtained by using setting 1 mm height torch, setting 2400 mm/min cutting speed, and setting 30 A electric current. Based on confirmation experiments, experiments with optimum parameter combinations can reach a gap noise of 2.283 dB. Therefore, the design of experiment for determining parameter setting Plasma Arc Machining can determine the optimum combination of parameters to minimize the surface roughness of the cutting results so that the workpiece is more precise and smooth. %Z Pembimbing: Ir.
