Answer 1

This is not a proper coding technique you were using. So please correct your model query code first like:
$query = $this->db->from('petugas')->order_by('id_petugas','ASC')->get()->result();
return $query;
No need to change anything else. You will get your all data in view.
I hope this will help you.

Answer 2

function get_user_all()
{
$query=$this->db->query("select * from petugas order by asc");
return $query->result();
$this->db->select('*');
$this->db->from('petugas');
$this->db->order_by('id_petugas','ASC');
$query=$this->db->get();
if($query->num_rows() > 0){
foreach($query->result() as $data){
$daftar[]= $data;
}
return $daftar;
}
}
