"I did not come to my graduation ceremony."
Translation:Aku tidak datang ke upacara wisudaku.
Yes, the more natural English sentence would use the word "go", wouldn't it?
I did not go to my graduation ceremony. Aku tidak menghadiri upacara wisudaku. (Using "pergi ke" sounds translationese to me.)
I don't think we use the word "pergi" often in such contexts. "Datang" or "menghadiri" (attend) are more commonly used.
