Here are a few ways to rewrite the title in a formal tone, depending on your focus:
Option 1 (Academic/Direct):
Constructing Imaginary Enemies: Misinformation, Disinformation, and ‘Foreign Agent’ Rhetoric in President Prabowo’s Indonesia
Option 2 (Policy-Oriented):
The Politics of Paranoia: Misinformation, Disinformation, and Foreign Influence Allegations Under the Prabowo Administration
Option 3 (Analytical):
Manufacturing Threats: An Analysis of Misinformation, Disinformation, and ‘Foreign Agent’ Narratives in Contemporary Indonesia
Recommendation:
Option 1 is the strongest choice if you want to maintain the punchiness of your original title while upgrading the vocabulary to sound more professional and academic.
