            $this->db->from('kategori_post');
            $this->db->order_by('nama_kategori_post','desc');

            $query = $this->db->get();

I am not sure but is this, kategori_model => Kategori_model, try once!! - Rahul
It seems that your model isn't being loaded. Did your model file is named kategori_model.php and it is under the model's path ? - DontVoteMeDown
Did you also use subdirectories for your models? You'd need to load admin/kategori_model. Docs: Loading a Model: If your model is located in a sub-directory, include the relative path from your models directory. - FirstOne

PHP is case sensitive, 

 public function __construct()
    {
        parent::__construct();
        $this->load->model('Kategori_model');
    }

your code showing that you're load the Kategori_model in capital,

public function index()
    {
        $kategori = $this->kategori_model->listing();
    }

but when you calling the model, you aren't using the capital at the kategori_model.

i suggest you to change it into :

$kategori = $this->Kategori_model->listing();

Try This Code 

public function __construct(){
    parent::__construct();
    $this->load->model('Kategori_model','km');
}
public function index(){
    $kategori = $this->km->listing();
}
