"Dia tidak menjaga keamanan rumahnya."

Translation: He does not guard his house's security.

[kuyaC]

Does this even make sense?

Awkward English. Suggestion: "He does not keep his house secured"

[MickIceWater]

Doesnt make sense. You cannot guard security. You provide security for a house or you guard the house

...i've just heen notified thru email by duolingo, so now i believe in english it would be:

he doesn't keep his house safe -or-
he doesn't maintain the safety of his house

...we shouldn't translate every word literally because not all words or expressions between languages are 100% equal

[dkfour]

In American English, this translation sounds like he is not protecting the people he hired to guard his house, which is not the meaning in Indonesian. Very poor translation.

[wrsurya]

sounds unnatural, better to say: 'the security of his home' rather than 'his house's security'

[wolfe.mcbr]

Maybe safety would be a better word than security?

Why not "is not guarding..."
