           Request request = new Request.Builder().url("http://" + urlpakai + "/utrapos/index.php/getpenawaran?id="+integers[0]).post(formBody).build();
           response = client.newCall(request).execute();
           ini = response.body().toString();
           JSONArray array = new JSONArray(ini);
           System.out.println("Saya Berkata: " + ini);
              for(int i=0; i<array.length();i++){
                 JSONObject object = array.getJSONObject(i);
                 DataJson hasil = new DataJson(object.getInt("id"), object.getString("kode"), object.getString("tglpenawaran"), object.getString("nama"), object.getString("supplier"), object.getString("nopenawaran"));
                 data.add(hasil);
              }
            }catch (IOException e){
               e.printStackTrace();
             }
             catch (JSONException e){
                e.printStackTrace();
             }
  return null;
 }

With minimum information you've shared, I'm assuming the error is at this line

JSONArray array = new JSONArray(ini);

The reason behind that is your ini. It should be

ini = response.body().string();

and not .toString()

Here is a sample code:

try {
        String responseData = response.body().string();
        JSONArray json = new JSONArray(responseData);
    } catch (JSONException e) {

    }
