Should 'Apakah' be included at the beginning? Since the question has a yes/no answer.
In the formal style, yes.
Starting a question with a question word (apa/apakah) is the way to go in the formal style (baku).
Maybe more or less the same as in English, where you could also phrase a question by changing the intonation.
You ordered beer ?
Did you order beer ?
The second form is probably the preferred form.
