In 2021, I published a book under Deepublish publisher which came in ebook and printed form. In this post I uploaded the excerpt (chapters 1 and 2) from the book. The full version of the ebook can be purchased from Google while the printed version can be purchased from Deepublish or other marketplace.
The book is fully in Bahasa Indonesia. For some of my international students, the excerpt file can be translated e.g. by Google.
