For Indonesia, last information I have was you can either:
Bring swab test results or pay for a swab test at Soetta and wait for the results (10+ hours possible) and quarantine at home for 14 days,
or have a 14 day quarantine at a government facility.
I came back to Jakarta from Ireland 11 days ago and I have completely isolated myself in my apartment. The regulation says 14 days. I have to admit when I got to the airport they were very careful to check my PCR test results etc but absolutely nobody told me about the need to do the 14 day at home quarantine and there was no info provided (no signs - nothing........).
I'm pretty sure they are not following up on any of the at home quarantiners.
I personally feel its my obligation to follow the rules and couldnt really live with myself if I subsequently got COVID and passed it to someone. A lot of the Indonesians on the flight from Abu Dhabi joined the "no-PCR test" queue beside me in the airport so I'm sure there is a risk that someone on that flight had it.
I dont recommend you come here for 3 days - what are you coming for??
