Then it is classified and analyzed based on the theory of code-mixing proposed by Muysken in his book entitled Bilingual Speech: A Typology of Code-Mixing (2000). To present the data, the informal method was used in presenting the data that was applied by providing explanations to describe and analyze the problems of code-mixing found in the data source.
