"Saya makan telur saat ini."

Translation: I am eating an egg now.

[anno35]

In English you have to have an article, (the or a/an). So the indefinite article 'an' needs to be added to the choice of words

[Rick392366]

Or make it plural.
I am eating eggs now.

You should report it, so that they can fix it.

[ingochris]

Can it mean "I am eating egg now."?

[AndreasRtz1]

"At the moment I'm eating eggs", why is this wrong?

[evebergin1]

Can sekarang be used here?

[KyrieDomineJesus]

Yes. Saat ini = [at] the moment.

Sekarang = now.

I think the usage whould differ about like this:

"I want to go to the cinema. Do you want to come?" - "I'll be with you in a sec, but I eat an egg now." (saat ini = it's only gonna take a moment)

"Lucas, you haven't done your chrores yet!!" - "But mooom, I'm eating an egg now!" (sekarang = no indication, how long the action is going to take)

[BJCJ19]

It would make sense if you put it in a dietary context e.g.

"Does your diet have egg in it?"
"Yes, I eat egg now."

[Aleksandro_RU]

I eat eggs this time?
