Answer 1

You forgot the $ sign in your controller. It should be:
$cek_master = $this->m_surveyor->cek_exist_master($this->input->post('EIR_REF'));

Answer 2

Maybe a typo?
$cek_master = this->m_surveyor->...
Should be
$cek_master = $this->m_surveyor->...

Answer 3

First check that you load your model "m_surveyor" into controller.

Answer 4

CONTROLLER.. Change in controller code
$cek_master =this->m_surveyor->cek_exist_master($this->input->post('EIR_REF'));
echo is_object($cek_master->row()) ? $cek_master->row()->REPAIR_ESTIMATE_ID : '';
