Questions & Answers about Saya presentasi besok pagi.

Is this sentence grammatical even though it looks like it’s missing a verb?

Yes. In everyday Indonesian, presentasi (normally a noun: “a presentation”) is commonly used as a verb meaning “to present/give a presentation.” So Saya presentasi is understood as “I’m presenting.” There’s no need for a separate “to be” verb in Indonesian.

Do I need to add akan to show the future?

No. Indonesian doesn’t mark tense on the verb; time words do the job. Besok pagi already makes it future. Adding akan is optional and can make the plan feel more explicit:

• Natural: Saya presentasi besok pagi.
• Also fine: Saya akan presentasi besok pagi. (slightly more deliberate/plan-like)

Is presentasi a noun or a verb here? When should I use other forms like mempresentasikan?

• Here, presentasi is used as a verb in casual/neutral speech.
• In more formal or careful Indonesian, prefer:
  
  • memberikan presentasi / melakukan presentasi = “to give/do a presentation.”
  • mempresentasikan + object = “to present something” (transitive). Example:
    
    • Saya akan mempresentasikan hasil riset besok pagi.
      Note: mempresentasikan is the standard spelling (not “memresentasikan”).

Is this sentence formal enough for work?
