Caused by the globalization of technology nowadays, many people tend to mix their language, especially Indonesian to English language in their conversations. So the problems formulated in this thesis are "what are the types of code mixing used by the first semester students of University of HKBP Nommensen Pematangsiantar in their conversation in the classroom, and what is the dominant code mixing used by the first semester students of University of HKBP Nommensen Pematangsiantar in their conversation in the classroom?" This research is a descriptive qualitative research because the collected data and the result of data analysis are in the form of sentences. The instrument in collecting the data is record and documentative technique. The data collected in this thesis is the recording of code mixing in the students'conversations. The data were analyzed based on Hoffman's theory. The result of this research that there are three types of code mixing found in students'conversation in the classroom. They are : intrasentential code mixing, intra-lexical of code mixing, and involving a change of pronunciation. Totally, there are 25 code mixing and 10 conversations representing code mixing. The percentage of intra-sentential code mixing is 24%, intra-lexical code mixing is 68%, and involving a change of pronunciation is 8%. From the percentage above, it can be concluded that intralexical code mixing is the most dominant code mixing used by first semester students of University of HKBP Nommensen Pematangsiantar in their conversation in the classroom. The findings implies that the code mixing is being accepted by the students as an important aspect variety of language in society. The Code Mixing in the Classroom Conversation of First Semester Students of University of HKBP Nommensen Pematangsiantar | 15 national examination that must be faced by each of school's level.

Picture 1. The Percentage of Code Mixing
The diagram above shows that the percentage of the three types of code mixing in students' conversations in the classroom. It can be seen that intra-sentential code mixing is 6 words with the percentage (24%), intra-lexical code mixing is 17 words with the percentage (68%), and involving a change of pronunciation is 2 with the percentage (8%). So totally, the code mixing found in students' conversation is 25 words. From the percentage, it shows intralexical code mixing is the dominant found in the students' conversation.
Based on the research findings above, the writer interprets the first semester students of University of HKBP Nommesen Pematangsiantar used types of code mixing in their conversation in the classroom. The students make 16 | Leonita Maria Efipanias Manihuruk three types of code mixing as in Hoffman theory (1991), they are: Intra-sentential code mixing, Intra-lexical code mixing, and Involving a change of pronunciation. Intra-sentential code mixing is type of code mixing which occurs within a phrase, clause, or a sentence boundary. The writer finds 6 intra-sentential code mixing from the data which have been collected and analyzed. They are: no problem, flash disk, hand phone, low bat, voice note, get well soon.
Intra-lexical code mixing is type of code mixing occurs within a word boundary. In this type, the writer finds 17 intra lexical code mixing. They are : read, error, upload, tag, open, download, quota, selfie, like, pin, invite, game, ok, wifi, check, searching, keep. Involving a change of pronunciation is type of code mixing occurs at phonological level, as when Indonesian people say an English word but modify it into Indonesian phonological structure.
