This research is motivated by the talk show Indonesia Lawyers Club having program quality, having recognition of awards, achieving high ratings, and presenting resource persons from social observers, politicians, lawyers, and the general public. This is interesting to study because in the event a lot of interference occurred because the speakers were presented from various backgrounds and different cultures. Then in this study the researchers focused on examining one of the speakers, namely, Sujiwo Tejo, and Karni Ilyas as a talk show host for the Indonesia Lawyers Club on Tv One.
 Sujiwo Tejo is an Indonesian actor, singer, writer and humanist who was born in Jember Regency. Sujiwo Tejo, who was born with Javanese blood, does not rule out the possibility that he will use his mother tongue when speaking. So when presented at the Indonesia Lawyers Club on TV One, Sujiwo tejo was a resource person who allowed interference events to occur when speaking in formal events. Karni Ilyas was born in West Sumatra, of Minangkabau blood. However, now living in Jakarta, so that he knows a lot and has many colleagues from various ethnic and cultural backgrounds, it also causes the possibility of interference events when speaking in formal events. The results of this study stated that interference was found at the morphological level including prefixes, suffixes, words, phrases, and clauses.
