This study aims to describe the morphological process errors in the speech of the
presenter and Ustad Wijayanto in the Famcast video collection on the Ustad
Wijayanto official YouTube channel. This research was carried out from the data
collection stage through the data analysis stage, using the listening and noting
techniques. The distributional method is used to analyze the data in this study, and
advanced techniques such as the deletion technique, dressing technique, expansion
technique, and insertion technique are applied. Informal and formal presentation
methods are used to present the results of data analysis in research. The results of the
morphological processing error data found in the speech of the presenter and Ustad
Wijayanto in this study were 216 affixation error data and 11 reduplication error
data. Affixation errors were found in 152 prefixes, 63 suffixes, and 1 confix. The
morphological process errors found in the speech of the presenter and Ustad
Wijayanto in the Famcat video collection on the official Ustad Wijayanto YouTube
channel were investigated based on the error and the correct morphological process
according to the theory. The data found from 6 types of morphological processes are
only errors in the affixation process and errors in the reduplication process. Each
morphological process has its own function and meaning, and the meaning contained
in the words found in this study was used to determine the repair of words that had
errors in the morphological process.
