The essence of early education is to provide some stimulation in order to optimize all children potential (body / physical or spiritual / mental), including the sorting of garbage that has not been optimally done in early childhood. There are many kinds of stimulation techniques for character education in early childhood, through sound, music, movement, touch, talking, singing, reading, matching, comparing, classifying, solving problems, scribbling, drawing, and stringing. The aim of this experiment is to determine the effect of stimulation of the picture media on character building discipline on sorting garbage at an early age children (4-6 years old) at Playgroup in Gamping, Sleman, Yogyakarta. The type of this research is Quasi Research with "Pre test Post test with Control Group Design". The research sample was taken by random sampling. The observation of control Grup was done twice. The first observation was to see the behavior of garbage sorting discipline before being given the stimulation and the second observation done after stimulation. Sampling was done by purposive sampling with criteria of children aged 4-6 years. Data examination results were analyzed descriptively and analytically with SPSS for windows version 16.0 using T-Test and Kendal Tau significance level of 0.05. The results showed that before treatment the mean value of garbage sorting discipline was 84.23, and the mean value after treatment was 95.88. The mean difference between the value of post and pre treatment groups was 11.65.
