Simulasi Numerik Model Matematika Vibrasi Dawai Flying Fox Menggunakan Metode Adams-Bashforth-Moulton

This study discusses numerical simulation using the Adams-Bashforth-Moulton (ABM) method of order 4 in flying fox string mathematical model which is form ordinary differential equations depending on time, consisting two equations, namely equation y(t) and angular θ(t). a that has been constructed by Kusumastuti, et al (2017) validated comparing analytical solutions to its Sari (2018). The analysis behavior Kusumastuti 2017 conducted Makfiroh (2020) shows phase portrait graph spiral with eigenvectors pointing towards equilibrium point so vibration can be concluded as valid close actual situation. attempts determine deflection angle Runge-Kutta was used generate 3 initial values for ABM. Next, comparison θ(t) solution graphs ABM performed 2018. first carried out when h=1, difference value fluctuated range [0,0.09] almost same graphic profile, 4, Runge-Kuta quite large different profiles. second h=0.01, fluctuating also ranged from [0.0.09] Runge -Kutta fluctuates [0,1] profile. So h=0.01 best displaying profiles Further research explore other methods.
