The prefix pe- and the affix -an are used to form nouns
Peralatan means equipment
The root is alat (noun) which means tool
Other words with this root: mengalati (to equip), memperalat (to use as an instrument)
‘Whose is this equipment’ is also correct?
That was my first guess, but, would that be "Peralatan ini siapa?"
Sam, totally agree. I said this also
