Code:
if ( ! $code_tags)
{
    echo 'Behold the power of the [code] tags!';
}

First of all, how about (Ooh look! Code tags! Big Grin):

Model:
Code:
function get_all_topikdo_jumlah()
{
  $this->db->select(‘topik_pembimbing1’);
  $this->db->select(‘topik_pembimbing2’);
   // No point doing this unless we're assigning the number of results to a variable.
  $data['total_rows'] = $this->db->count_all_results(‘topik’);
  

  $this->db->from(‘topik’);
  $this->db->from(‘dosen’);
  $this->db->where(‘dosen_id’,‘topik_pembimbing1’);
  $this->db->or_where(‘dosen_id’,‘topik_pembimbing2’);
  $data['results'] = $this->db->get()->result();

  return $data;
}

$data['jumlah'] is an array of objects, which is why echoing that is causing an error. What is this variable for? I don't understand. If you're expecting it to contain a string, you need to extract that from the database result.

Also, if you're only expecting a single row, it would make sense to limit your query to a single result, and use result_row() instead of result()
