"Hati-hati di Jakarta."

Translation: Be careful in Jakarta.

"Livers in Jakarta" should be accepted! :P

"take care in Jakarta" should be accepted, no?

I agree. As ever, the choice of English would depend upon the context: is someone about to step into danger (which might be 'Be careful!') or are they about to set out on a car journey ('Take care!'). Reported.

I think take care and be careful are equivalent in English.
