Questions & Answers about Sesi praktik diadakan besok pagi.

What does each word mean, and how is the verb formed?

• sesi: session
• praktik: practical/practice (hands-on)
• diadakan: is/are held (passive). Built from ada (exist) + -kan (causative → “make exist,” adakan) + passive prefix di- → diadakan
• besok: tomorrow
• pagi: morning

Why is there no subject? Who is doing the holding?

Indonesian often uses a passive verb with no agent when the doer is unknown, unimportant, or obvious from context. Diadakan is passive; the agent is simply not stated.

Why use the passive diadakan here? Could I use the active voice?

Passive focuses on the event, which is natural in announcements. Active is fine if you want to name the organizer:

• Active: Kami/Kampus akan mengadakan sesi praktik besok pagi.
• Passive with agent: Sesi praktik diadakan oleh panitia besok pagi.
• “Short passive” (very common): Sesi praktik (akan) kita adakan besok pagi.

Do I need akan to talk about the future?

No. Indonesian doesn’t require tense marking. The time word besok already signals the future. Akan is optional for clarity or formality:

• Sesi praktik diadakan besok pagi.
• Sesi praktik akan diadakan besok pagi. (slightly more formal/explicit)

Should I put pada before the time, like pada besok pagi?

No. You normally say besok pagi without a preposition. Pada is used more with days/dates (often optional): (pada) hari Senin, (pada) 12 Mei. With “tomorrow morning,” just use besok pagi.

Where can the time expression go in the sentence?

Time can go at the end or the beginning:

• Sesi praktik diadakan besok pagi.
• Besok pagi, sesi praktik diadakan.
• With an agent: Besok pagi, sesi praktik diadakan oleh panitia.

Is diadakan one word, or should it be written di adakan?

One word: diadakan. Here di- is a verb prefix. Write di separately only when it’s a preposition meaning “at/in/on,” e.g., di rumah. Also note the standard spelling is praktik (not praktek), though praktek is common informally.

What’s the difference between diadakan, diselenggarakan, and dilaksanakan?

• diadakan: general “held/organized.” Neutral and common.
• diselenggarakan: more formal; highlights the organizing body/arrangement.
• dilaksanakan: “carried out/implemented”; emphasizes execution.
  They often overlap in announcements.

How can I mention who is organizing it?

Add an agent with oleh, or switch to active:

• Sesi praktik diadakan oleh panitia besok pagi.
• Panitia akan mengadakan sesi praktik besok pagi.

How would people say this casually?

• Besok pagi ada sesi praktik. (There’s a practice session tomorrow morning.)
• Sesi praktik diadain besok pagi. (Colloquial/Jakarta-style for diadakan.)
• Sesi praktiknya besok pagi. (“The practice session is tomorrow morning,” with -nya marking a specific/known session.)

Can I say pagi besok or esok pagi instead of besok pagi?

• besok pagi: most common.
• pagi besok: possible, a bit less common; can emphasize “morning.”
• esok pagi: more formal/literary; used in news or formal writing.

How do I negate the sentence?

• Neutral: Sesi praktik tidak diadakan besok pagi. (not held tomorrow morning)
• If it’s a cancellation, more natural:
  
  • Sesi praktik besok pagi dibatalkan.
  • Sesi praktik tidak jadi diadakan besok pagi.

How do I add the exact clock time?

Use pukul or jam:

• Sesi praktik diadakan besok pagi pukul/jam 9.
• For 9:30: pukul setengah sepuluh (literally “half to ten”) or pukul 09.30.

What if there are multiple sessions?

Use a number or a quantifier; reduplication is optional and stylistic:

• Dua sesi praktik diadakan besok pagi.
• Beberapa sesi praktik diadakan besok pagi.
• Sesi-sesi praktik diadakan besok pagi. (emphasizes plurality; more formal/written)

What does the suffix -kan contribute in adakan/diadakan/mengadakan?

-kan is often causative. From ada (exist) + -kan → adakan (“make exist,” hence “hold/put on”).

• mengadakan: to hold/organize (active)
• diadakan: to be held (passive)

How do I make “the practice session” sound definite/specific?

Add -nya to the noun phrase:

• Sesi praktiknya diadakan besok pagi.
  Here -nya roughly corresponds to “the/that” when context makes the session specific.
