"Jangan ada yang memisahkan kalian."

Translation: Do not let anything separate you.

[RobertEddy]

Where is the "let anything" idea shown in the Indonesian in this sentence?

[Rick392366]

'ada' = there is (presence).
'ada yang' = there is something that.
'ada yang memisahkan kalian.' = there is something that separates you.

'jangan' is a negation used in imperatives.

'Jangan ada yang memisahkan kalian.' = Don't let there be something that separates you.
'Jangan ada yang memisahkan kalian.' = Don't let anything separate you.

I would say a better translation is "jangan izin/ijin apa pun (or sesuatu, but not the same) memisahkan kalian"
