That looks more like a flower bud than a fruit. Where was it found?

Thanks for responding, after researching web, I have found this is a named Zingiber striolatum. a kind of ginger. can it be a vegetable or medicine. I tasted it is very good.

Oh, my friend planted it as veggies, but he does not know what is the name.

it looks like Etlingera elatior

I saw it already. It's in the wild.

In Indonesia it is known as Zingiber mioga.

And the scientific classification is

Kingdom: Plantae. Subkingdom: Tracheobionta. Superdivision: Spermatophyta. Division: Magnoliophyta.

On the kulinerekstrim.com site, there are many types of plants like that that can be eaten, even though they are considered scary.
