              'namaBarang'  => $row['nama_barang'],
              'stock'       => $row['stock'],

You can solve this issue using the following code.

    foreach ($data->toArray() as $key => $value) {
      foreach ($value as $row_key => $row) {
        $insert_data[] = array(
          'kodeBarang'  => $row[0],
          'namaBarang'  => $row[1],
          'stock'       => $row[2],
          'hargaJual'   => $row[3],
          'kategory'    => $row[4]
        );
      }
    }
