Entering Korea with a Indonesia passport

What we found on official pages, with the date we checked.

In short

Travelling on your own with an Indonesia passport, you need a visa.
Groups of 3 or more booked through a designated Indonesian travel agency can enter visa-free for up to 15 days, until 31 Dec 2026.
With a visa you also fill in an arrival card. The e-Arrival card can be sent online from 3 days before you arrive.

Indonesia is not on the visa-free list, so individual travellers need a visa.
