World Complexity in BIPA Textbook Levels A-C as Materials for Indonesian Vocabulary Mastering for Foreign Speaker

Abstract

One of the things that foreign speakers find difficult when learning Indonesian is the form of derivation. Foreign speakers find it difficult to distinguish the use of affixed words. One of the books used as a reference in learning Indonesian is the A-C level BIPA textbook published by Badan Bahasa. In the book, there is various vocabulary that foreign speakers can learn. The problem is that the book's vocabulary does not always show the level of complexity that is in line with the level of the book. Based on this, it is necessary to study the complexity of words in BIPA textbooks as a material for mastering Indonesian vocabulary for foreign speakers. Data collection used the documentation method to obtain the corpus of data from the BIPA A-C textbook. The comparative method was used for data analysis. As a result, there is an increase in word complexity from simple to complex words at each level of the BIPA textbook. The level of complexity is not clearly defined, meaning that there is still overlap between levels of BIPA textbooks. Changing simple words into complex words is not explained in the BIPA textbook.
