Cron Job Using Codeigniter And CLI

Question

i have a function that need run every day at 00:00 AM, i do some research but not any result coming up with my cron job.

this is my function code :

public function aro()
 {
      $this->deposito_m->exec_aro();
      echo 'oke';
 }

my deposito_m is:

function exec_aro()
 {
      $tgl_now = date('Y-m-d');
      $data = $this->get_data_deposito_aro($tgl_now);
      if (!empty($data)) {
           foreach ($data as $x) {
                $transaksi = $x->tgl_transaksi;
                $tgl_awal = substr($transaksi, 0, 10);
                $jenis_ang = $x->jenis_ang;
                $tanggal_berakhir = date('Y-m-d', strtotime("+" . $jenis_ang . " months", strtotime($tgl_awal)));
                $anggota_id = $x->anggota_id;
                $akun = $x->akun;
                $dk = $x->DK;
                // $tanggal_berakhir = $x->tgl_berakhir;
                $kas_id = $x->kas_id;
                $user_name = $x->user_name;
                $nama_penyetor = $x->nama_penyetor;
                $no_identitas = $x->no_identitas;
                $alamat = $x->alamat;
                $jumlah_awal = $x->jumlah;
                $conf_bunga = $this->bunga_m->get_key_val();
                $bunga_deposit = $conf_bunga['suku_bunga_deposit'];
                $pajak = $conf_bunga['pajak_depo'];
                $bunga = $jumlah_awal * ($bunga_deposit / 100) * ($x->jenis_ang / 12);
                $total_bunga = $bunga -  ($bunga * ($pajak / 100));
                $jumlah = $jumlah_awal + $total_bunga;
                $create_arr = array(
                     'tgl_transaksi' => $tgl_now,
                     'anggota_id'    => $anggota_id,
                     'jenis_ang'     => $jenis_ang,
                     'jumlah'        => $jumlah,
                     'keterangan'    => 'new',
                     'akun'          => $akun,
                     'DK'            => $dk,
                     'kas_id'        => $kas_id,
                     'tgl_berakhir' => $tanggal_berakhir,
                     'update_data'   => $tgl_now,
                     'user_name'     => $user_name,
                     'no_identitas'  => $no_identitas,
                     'alamat'        => $alamat,
                     'nama_penyetor' => $nama_penyetor,
                     'status'        => 'on_progress',
                );
                $this->db->insert('tbl_trans_dep', $create_arr);
           }
      } else {
           return 'tidak ada data';
      }
 }

my crontab -l in server is :

0 0 * * * /usr/bin/php /home/admin/web/kspspmi.dieselone.co.id/public_html/index.php deposito_status/aro

i try with * * * * * to know my cron is running or not, in log there is some CMD running but nothing happens with my data in database.

I try run my crontab script at my CLI and returning:
