"Mengapa kamu ingin hidung kamu diperbesar?"

Translation: Why do you want your nose to be made bigger?

[RobertEddy]

Why is enlarged wrong while to be made bigger is right?

[Rick392366]

Both should be okay.

[MartinBahasa]

the whole sentence would need to be "Why do you want your nose to be enlarged" so not only "enlarged" but "to be enlarged" same as "to be made"
