摘要：Internet is a Media of Information and Communication Technology that is growing rapidly and in great demand by the
public. This is evident from the number of users that increase each year. Internet is used by adults and children. The result of the
national socio-economic survey 2016 showed that 6.91% of children aged 5-12 years old accessed the Internet. The ease of accessing
the Internet becomes a problem when children use the Internet excessively. Increasing the number of children as Internet users need to
be monitored to overcome the adverse impact of Internet use. One way is to know the characteristics of children as Internet users.
Classification is an operation that places objects on a particular class based on its characteristics. In this study, we used a classification
tree to form the classification of children as Internet users category of 5-12 years. We used data from the National Social Economic
Survey surveyed by the Central Agency on Statistics in 2016 in Indonesia. The imbalance of data caused the insensitivity of the
resulting classification to minority data. Handling imbalance data was applied using oversampling and under sampling.The objectives
of this study are to determine the characteristics of children as Internet users, to see the effect of oversampling and under sampling, and
to see the results of classification accuracy. The result was oversampling and under sampling increase sensitivity about 45%. Based on
classification tree, it was known that children of Internet users were characterized by children who live in households with Internet
expenditure of at least Rp.100.000 per month with many household members accessing the Internet.
