Analysis of Language Errors and Their Relevance as Advanced Indonesian Language Teaching Materials

Abstract

Language has rules that must be obeyed so it can be used properly and to reduce language deviations. However, in reality there are still many language users who make errors, especially in the field of phonology. This study aims to describe errors in the use of Indonesian language at the phonological level in a self-development book entitled Seharusnya Memang Tidak Begini Begitu by Astin Musman. The research method used is qualitative descriptive. The data collection technique is observation and note taking, which is done scrutinizing the words and sentences in the book which contain phonological errors. The results of this study indicate that there are three language errors at the phonological level in the form of: (1) errors in using capital letters (7 words), (2) errors in using full stop at the end of sentences (8), and (3) errors in writing 47 vocabularies. Vocabulary writing errors are divided into three, which are the omission of 18 vocabulary phonemes, the addition of 9 vocabulary phonemes, and the phonemes change of 20 vocabulary words.
