Questions & Answers about Dosen kami menjelaskan siapa yang bertanggung jawab mengirim draf dan siapa yang mengeditnya.

Is this sentence a question? It has siapa (“who”) in it.

No, it is not a question. It is a statement that contains embedded questions (indirect questions).

• Direct question:

  • Siapa yang bertanggung jawab mengirim draf?
    Who is responsible for sending the draft?

• Indirect/embedded question (as in your sentence):

  • Dosen kami menjelaskan siapa yang bertanggung jawab mengirim draf...
    Our lecturer explained who is responsible for sending the draft...

In Indonesian, using a question word like siapa, apa, di mana inside a larger sentence does not automatically make the whole sentence a question. The sentence becomes a question only if the main clause itself is interrogative (usually shown by intonation or a question mark and sometimes the word apakah).
