Language and culture could not be learned and taught separately. A learning material based on culture becomes an essential consideration for a meaningful instructional process. This study a i m s t o develop a culture-based textbook for academic purposes using a model of teaching language and culture. This model includes linguistic knowledge, linguistic awareness, cultural awareness, and cultural experience. The first step (need assessment) concerning the need to develop a culture-based textbook was done in the previous study by Zuchdi and Nurhadi (2019), while the level of students' language competence and their cultural interest was done at the beginning of this study. The development process involved defining objectives, identifying cultural topics, creating instructional materials and media, designing content layouts and graphics, conducting internal and external reviews, product validation through trial, and generating the final draft. Based on the survey, most respondents were at the proficiency levels of 3 and 4 in their Indonesian language competence, guiding the development of the textbook for those levels. The respondents were students enrolled in the Indonesian language program at Ahmad Dahlan University in Yogyakarta. The data were collected through a pretest-posttest design and instructor’s reflection. The pretest scores were analyzed by comparing them to the post-test scores, focusing on the distribution across categories. Notably, while almost half of the pretest scores fell into the low and medium categories, all post-test scores were in the high category, demonstrating a significant improvement. The instructor's reflection also indicated that students were actively engaged in studying using the textbook. It can be concluded that the culture-based Indonesian language textbook for academic purposes is influential in teaching and learning Indonesian as a foreign language. © 2023, author.
