"Apa kamu bisa makan sendiri?"

Translation: Can you eat by yourself?

[evabstracted]

Shuldn't here be Apakah instead of Apa? Apakah is used for yes/no questions and this is such a type of question.

[demoksaputra]

Apa and apakah are the same. Although, apakah is more formal than apa. The suffix –kah is used to turn regular question sentence into a more polite form.

What is the role of bisa in this sentence? i understand what it means but how does the sentence change without it?

Not a native speaker, but this is what I understand.
