you are updating the text view in the different thread(not the UI thread). you can update the view in two ways:

update the text view by running it on the ui thread. ref- https://developer.android.com/reference/android/app/Activity#runonuithread
You can return the result in doInBackground and update the text view in onPostExecute

There is a only one Thread running which is UI Main Thread, and it doesn't allowed to update UI from thread process.

So there is a solution if you want to set the TextView inside the doInBackground() method, do the UI updating operations inside the runOnUiThread method.

runOnUiThread(new Runnable() {
               @Override
               public void run() {
                   try {
                    JSONObject data = json.getJSONObject("sys");

                    baik = Integer.parseInt(asetBaik.getText().toString());
                    baik = data.getInt("sunrise");
                    asetBaik.setText(baik);

                } catch (JSONException e) {
                    e.printStackTrace();
                }     
               }
            });

Hope it will help you!!

replace this code

baik = Integer.parseInt(asetBaik.getText().toString());
baik = data.getInt("sunrise");
asetBaik.setText(baik);

to

baik = data.getInt("sunrise");
asetBaik.setText(String.valueOf(baik));

Hope this will work

I Hope this will work for you.

 try {

         JSONObject jsonObject1= json.getJSONObject("sys");
         int sunrise = jsonObject1.getInt("sunrise");
         int sunset = jsonObject1.getInt("sunset");
         Log.e("sunrise", "" + sunrise);
         Log.e("sunset", "" + sunset);

       } catch (Exception e) {

   }

you are using asynctask you need to use handler to update the UI on main thread
