This study analyzes types of themes and theme shifts in the English - Indonesian
translation of Barrac Obama’s speech in Universitas Indonesia. The result shows that topical
theme dominates the entire texts 71.43% in ST and 79.64% in TT. Interpersonal theme is the
least theme found in both texts. Most topical themes are in participants, followed by
circumstance and process. The textual theme in both texts is adjunct conjunctive. The
interpersonal themes are modals. Most of the themes are considered as equivalent. The theme
shift occurs through three processes: by changing the grammatical function within the theme
by adding more themes and by deleting themes
