回答1:

Cursor cursorKontak should be cursorEnkripsi

Cursor cursorEnkripsi = data.pilihEnkripsi(ciper);
    if(cursorEnkripsi.moveToFirst()) {
        //idenkripsi = cursorKontak.getString(cursorKontak.getColumnIndex("idenkripsi"));
          idenkripsi = cursorEnkripsi.getString(cursorEnkripsi.getColumnIndex("idenkripsi"));
    }
