upload is not a class it is a function of a class named as Pendaftaran. So to call this function from another function within the same controller use $this->function_name(). Try like this..

Replace 

   $obj = new upload();
   $nama_foto = $obj->$nama;

With

$nama_foto = $this->upload();//calls upload function
echo $nama_foto;//test photo name here

And in upload() method:

public function upload(){
    if(!empty($_FILES))
    {
        $config["upload_path"] = "./uploads/images";
        $config["allowed_types"] = "gif|jpg|png";
        $this->load->library('upload', $config);

        if($this->upload->do_upload("file")){
            $nama=$this->upload->data('file_name');
            return $nama;
        }
        else if(!$this->upload->do_upload("file")){
            echo "failed to upload file(s)";
            exit;
        }
    }
}
