Abstract
This study aims to 1) design and create a damped harmonic oscillator as a learning media for damped harmonic oscillation, 2) to know the effect of the displacement on the number of waves formed and the wave period until the oscillation is stopped. The method used in this research is Design and Development Research (DDR). The specific phase of development consists of analysis, design, development, and evaluation. This research was conducted at one of the universities in Lampung. The subjects were 57 physics education students who taught the wave course. The damped harmonic oscillator consists of two systems: the first system consists of a paper drive system and the second system consists of pendulum and spring. The research results are: 1) DHO was made as a learning media on the topic of oscillation. 2) the value of displacement given affected the amplitude and wavelength as well as its period, but only slightly affected the damping coefficient 3) based on the results of usability test given to 57 students it showed that DHO is “good” to be used for teaching the subject of damped harmonic oscillations.
