}
return $this->db->get_where($this->tbl_berita, array('id' => $id, 'slug' => $slug),1)->row();

You can use one of CodeIgniters helper functions url_title()
Takes a string as input and creates a human-friendly URL string. This
is useful if, for example, you have a blog in which you'd like to use
the title of your entries in the URL.
site_url("articles/{ID}/").url_title({TITLE});
