This study aims to find out the influence of differential reinforcement of other behavior (DRO) programs to reduce maladaptive behavior or behaviors that should not appear in children with disabilities that occur during home learning due to online. The research approach uses quantitative research with this type of experimental research. The experimental approach used is the Single Subject Research approach. The design used is the A1-B-A2 design. The study subjects were students with disabilities in class II SDLB – B Karya Mulia II in Surabaya. Data collection through descriptive statistics and displayed in graph form. The components analyzed are analysis under conditions.

The results showed a decrease in the duration of time and frequency of maladaptive behavior shown by the subjects. Based on the duration and frequency of the appearance of the subject's behavioral targets it is known that the estimated results of the directional slack increase during the baseline phase 1, decrease during the intervention phase, and decrease in the baseline phase 2. It can be concluded, the use of differential reinforcement of other behavior (DRO) program can reduce maladaptive behavior.
