A Personal Blog


In case you're wondering: Raihan Kalla is just an anagram of my full name. I make tiny 'cinematic' Stories on Instagram (check my highlights!) and curate science & short documentaries on YouTube (check my hand-picked playlists!). I'm also doing research in media studies at University of Indonesia, studying data science, and teaching myself filmmaking. Curious how these interests and hobbies will collide in the future.

Buat sebagian besar dari demografi seperti mereka, urusan pandemi Corona ini jadi pukulan sejadi-jadinya.



When I was 9 years old, I stumbled upon a book of my father’s. The title read Samudra Al-Fatihah. The cover was worn out, and I don’t quite remember what made me spent hours reading a chapter from that book. But I remember what I read, because that was my oldest memory, the first time my mind being blown away learning about the grandeur of the universe.
