They had announced the hunger strike on Sunday after knowing that the two divisions were not unified in the meeting of the Faculty of Engineering.
According to the announcement, students of the APE Department sat on hunger strike from Monday morning. Five students have already been ill.
But the decision on whether the division will be unified will be decided on Wednesday at the Academic Council.
Meanwhile, from November 16, the students of the EEE department have kept counter-measures against the division integration. They said they will remain firm on their demand.
