"Tujuan tes ini adalah untuk meningkatkan keamanan."
Terjemahan:The purpose of this test is to improve safety.
both are about protection but security is against active risks, safety more passive. For example, the 'President has a security guard because he is at risk of being shot', 'I wear my seatbelt because I am concerned about safety'.
I think the translation here is wrong. Keamanan = security. Safety = keselamatan.
