Android : Sum up data from JSON

I have some JSON data to sum but I get an error. This is my code:

protected String doInBackground(Object... params)
{
    JSONParser jParser = new JSONParser();
    JSONObject json = jParser.AmbilJson(link_url);
    int Total = 0;
    try
    {
        pesanan = json.getJSONArray("pesanan");
        for (int i = 0; i < pesanan.length(); i++)
        {
            JSONObject ar = pesanan.getJSONObject(i);
            Total = ar.getInt("Total");
            Jumlah = Jumlah + Total;
        }
    }
    catch (JSONException e)
    {
        e.printStackTrace();
    }
    return null;
}

@Override
protected void onPostExecute(String s)
{
    super.onPostExecute(s);
    Totalbayar.setText(Jumlah);

JSON data:

{"pesanan" : [{"Total" : "20000"}{"Total" : "10000"}{"Total" : "27000"}]}

Logcat:

07-08 08:25:50.447: E/JSON Parser(621): Error parsing data org.json.JSONException: Unterminated array at character 34 of {"pesanan" : [{"Total" : "20000"}{"Total" : "10000"}{"Total" : "27000"}]}
