ABSTRACT ud ud udAPPLICATION OF GENETIC ALGORITHM TO THE SHAPE udOPTIMIZATION OF DOUBLE HEMLHOLTZ RESONATOR USE THE udMATLAB 7.0 ud udBy udNoval Bramantyo udM0200038 ud ud udResearch on shape optimization of double Helmholtz resonator with the udgenetic algorithm method has been done by using MATLAB 7.0. Research has udconducted by designing of Helmholtz resonator characteristics, then it, use as fitness udfunction in the genetic algorithm. Genetic algorithm parameter has variation to get udthe best fitness and then analyzed. ud Result of analysis indicate that the best of parameter for the frequency of (50, ud150, 250, 350, 450, 550, 650, 750, 850, 950)Hz is Grefenstette(2) (PopSize=80 , udPc=0,45 , Pm=0,01), and the best of double Helmholtz resonator design for the udfrequency above successively is ((V=0,01159m3ud, L=0,01574m, b S=0,00032m2ud, udS=0,00281m2ud), (V=0,00351m3ud, L=0,00414m, b S=0,00085m2ud, S=0,00204m2ud), ud(V=0,00145m3ud, L=0,00020m, b S=0,00086m2ud, S=0,00162m2ud), (V=0,00044m3ud, udL=0,01957m, b S=0,00086m2ud, S=0,00160m2ud), (V=0,00044m3ud, L=0,00082m, udb S=0,00087m2ud, S=0,00163m2ud), (V=0,00018m3ud, L=0,02137m, b S=0,00090m2ud, udS=0,00160m2ud), (V=0,00018m3ud, L=0,00457m, b S=0,00079m2ud, S=0,00163m2ud), ud(V=0,00013m3ud, L=0,00520m, b S=0,00082m2ud, S=0,00237m2ud), (V=0,00009m3ud, udL=0,01293m, b S=0,00090m2ud, S=0,00160m2ud), (V=0,00005m3ud, L=0,02457m, udb S=0,00067m2ud, S=0,00160m2ud)).
