The expression 'Who's on duty today ?' is often used at school. Does it concern nurses and police officers or pupils at scool too?
What sort of work or task should be assigned? Sweeping the floor and cleaning th blackboard or a little bit challenging task?
I presume it would be something appropriate to the person's age level.
This expression is used to start a lesson. It means somebody have to come over the blackboard and clean it. Is it corrrect?
I know 'come over here'. Is it right 'come over (the)blackboard'?

Come over to the blackboard.
Come over to the blackboard, and wipe it clean.
I mean to use the question 'who's on duty today?' for this purpose. To say directly 'Come over to the blackboard, and wipe it clean.' seems much better.
If someone is allocated the task of cleaning the blackboard in each class, you could ask "Who's on blackboard duty today?" When the relevant student raises his/her hand, the teacher might say "Why isn't my blackboard clean then?"
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
