mempan

Aku tahu peluru bius tak lagi mempan pada prajurit Centipede,.. ..tapi kita hanya perlu melumpuhkan mereka, bukan membunuhnya.

I know the night-night rounds no longer affect the Centipede soldiers, but all we want to do is disable them, not kill them.

Sudah tak mempan lagi.

It's not... don't work anymore.

Tidak mempan, serangan-ku cuma bagai "Angin Lalu"...

They're dodging me. My energy is missing them by a hair's breadth...

Tak mempan.

That doesn't do any good.

Serangannya tidak mempan sedikitpun padanya.

It doesn't work on him at all.
