Abstract: A textbook as foreign language teaching material is widely used by formal institutions. Sebelas Maret University, Surakarta uses the textbook of Bahasa Indonesia bagi Penutur Asing (BIPA) or Teaching Indonesian to Speaker of other Language (TISOL) as one of the teaching materials to learn Indonesian for foreign students. This study examines the frequency containing nouns, verbs and adjectives in two BIPA textbooks, Sahabatku Indonesia (SI) and Keren! Indonesian Course Book (KICB). This study used AntConc analysis tool to determine the number of frequencies of each classification of word. The results of this study indicate the high percentage of nouns, verbs, and adjectives, i.e. 63.16% for SI textbook and 67.06% for KICB textbook. However, the specific percentage of verbs is 19.06%, and adjective is 3% in textbook SI; the percentage of verbs is 13.46%, and that of adjectives is 6.95% in textbook KICB. This generated unbalanced acquisition of new vocabulary mastered by foreign students. Hopefully, the author of the book can give nearly equal percentages of the nouns, verbs, and adjectives in order for vocabulary mastery of foreign students evenly for all types of words so that they can be well used in spoken and written languages.
