This thesis is titled "Analysis of Mediamorphosis of Radio Rasi FM Magetan". The purpose of this study is to determine whether mediamorphosis affects Radio Rasi FM Magetan. This research uses a qualitative descriptive research method and uses a constructivist paradigm. Data collection techniques were used using interview and observation techniques. This study focuses on 3 mediamorphosis concepts, namely coevolution, convergence, and complexity using mediamorphosis theory by Roger Fidler in his book entitled Mediamorphosis: Understanding New Media, to see changes in communication media. The discussion is analyzed through interview results and uses interpretation. There are 2 informants in this study, all of whom are from Radio Rasi FM Magetan, and 1 key informant, namely the Head of Radio Rasi FM Magetan Studio and 1 ordinary informant, namely the announcer. From the results of the analysis, a discussion was obtained regarding the 3 concepts of mediamorphosis, namely coevolution, convergence, and complexity. The research results show that mediamorphosis affects Radio Rasi FM Magetan and it can be concluded that mediamorphosis has an influence on the development of mediamorphosis. This research is expected to be able to provide valuable contributions in the context of the development of local radio in the digital era.
