You have to change this line of code in your controller:

 function index(){
    $data['filedata'] = $this->m_data->tampil_data();
    $this->load->view('viewdata',$data);
}

and this in your model code:

   function tampil_data(){
       return $this->db->get('formpengajuan')->result();
   }

and if you are not auto loading your database then load it in your controllers by adding this lines

 function __construct(){  
    parent::__construct(); 
    $this->load->database();
 }

Let me know if these changes did help you to solve your problem.
