Answer 1

Try to add level to your session and read it later on dashboard page:

        $session = array(
            'id'=> $d->admin_id,
            'nama'=> $d->admin_nama,
            'status' => 'login',
            'level' => $d->level
        );

And on dashboard page

if($this->session->userdata["level"] === "superadmin")
{
   // Code if level = superadmin
}
