"Siapa yang berani membuka pintu itu?"

Translation: Who dares to open that door?

[hikagesan]

"Who is brave enough to open that door?"

[Sjlver]

Yes, that would certainly be a valid translation.

Who dares to open that door? is also valid. I think there should be the "to" though (not simply "who dares open ...").

[NipQ44]

Who is game to open that door?

[Meta_Taro]

Brave, daring, close enough.
