$paragraph = explode("</p>", $rows['isi_berita']);
									if (empty($paragraph[3])){
										$content = $paragraph[0].$paragraph[1].$paragraph[2]."</p>";
									}else{
										$content = $paragraph[0].$paragraph[1].$paragraph[2]."</p>";
										$content .= "<h4>Baca Lainnya : </h4><ul>";
												$pisah_kata  = explode(",",$rows['tag']);
												$jml_katakan = (integer)count($pisah_kata);
												$jml_kata = $jml_katakan-1; 
												$ambil_id = substr($rows['id_berita'],0,4);
												$cari = "SELECT * FROM berita WHERE (id_berita<'$ambil_id') and (id_berita!='$ambil_id') and (" ;
												for ($i=0; $i<=$jml_kata; $i++){
												$cari .= "tag LIKE '%$pisah_kata[$i]%'";
												if ($i < $jml_kata ){
												$cari .= " OR ";}}
												$cari .= ") ORDER BY id_berita DESC LIMIT 5";
												$hasil  = $this->db->query($cari);
												foreach ($hasil->result_array() as $row) {	
													$total_komentar_terkait = $this->model_utama->view_where('komentar',array('id_berita' => $row['id_berita']))->num_rows();
													$content .= "<li style='padding:0px'><a style='color:blue' href='".base_url()."$row[judul_seo]''>$row[judul]</a><a href='#' class='h-comment'>$total_komentar_terkait</a></li>";
												}      
												$content .= "</ul>";
 
										for ($i=3; $i <=count($paragraph)-1 ; $i++) { 
											$content .= $paragraph[$i];
										}
									}
