Answer 1

try changing your model query as like this
function update_lokasi($id,$data){
$this->db->where('id_monitor', $id);
$this->db->update('frm_monitor', $data);
}
Before that make sure that the post for 'kd_monitor' in the controller is not null

Answer 2

You should rename the $data variable being passed to $this->M_monitor->update_lokasi() because it will overwrite $data that is going to be passed to $this->M_data_aset->insert() with only 'lokasi_monitor' array on it. Or even better try rename both $data to prevent confusion.
Modify your controller :
{
$this->_rules();
if ($this->form_validation->run() == FALSE) {
$this->create();
} else {
$data_aset = array(
'lokasi_aset' => $this->input->post('lokasi_aset',TRUE),
'monitor_aset' => $this->input->post('monitor_aset',TRUE),
);
$id = $this->input->post('kd_monitor', TRUE);
$data_monitor = array(
'lokasi_monitor' => $this->input->post('lokasi_aset'),
);
$this->M_monitor->update_lokasi($id,$data_monitor);
$this->M_data_aset->insert($data_aset);
redirect(site_url('data_aset'));
}
}
And change 'frm_monitor' to 'kd_monitor' on the conditional query :
function update_lokasi($id,$data){
$this->db->where('kd_monitor', $id);
$this->db->update('frm_monitor', $data);
}
