The perturbation method is used to see changes in solutions that occur when attenuation is of little value, as in the phenomenon of waves with weak attenuation and which subjected to coercive force. Therefore this study aims to find solutions to solve the wave equations that experience weak attenuation and which subjected to coercive force. The method used is the study of literature and computation with MatLab. Based on the research results obtained that analytically non-homogeneous waveforms can not provide general solutions for differential resolution. Whereas computationally the results obtained are, the wave model with weak attenuation and the wave model with coercive force have amplitude values that change for time and for time wave models that subjected to coercive force has an amplitude value that increases compared to without coercive force. © Published under licence by IOP Publishing Ltd.
