Learn Hardcore Indonesian: Latihan dasar dimulai pukul delapan. - The basic training starts at eight o'clock.

Pukul literally means to strike (as in a clock striking) but in time expressions it means o’clock. It’s common in formal/neutral statements and announcements: pukul delapan. Jam also means hour/clock and is very common in everyday speech: jam delapan. Both are correct; pukul feels a bit more formal.

Do I need a preposition like “at” before the time?

No. Indonesian often omits pada (at) before times. Dimulai pukul delapan is perfectly natural. Adding pada (dimulai pada pukul delapan) is also correct and a bit more formal.

What’s the difference between mulai, memulai, and dimulai?

mulai = to start (intransitive). Example: Latihan dasar mulai pukul delapan.
memulai = to start something (transitive). Example: Instruktur memulai latihan dasar pukul delapan.
dimulai = is started (passive). Example: Latihan dasar dimulai pukul delapan. You can add an agent with oleh if needed: dimulai oleh instruktur.

Is Latihan dasar mulai pukul delapan also correct?

Yes. Using mulai instead of dimulai is common and slightly less formal. It presents the event as starting on its own, without highlighting an external actor.
