$arr = $this->input->post('serv'); //it will contain value in arrray format
foreach($arr as $k=>$v)
{
    $data = array(
            'service_name' => $v,
            'dr_id' => $this->input->post('d_id'),
            );
        $this->insert_model->service_insert($data);
}

Use insert_batch()

public function submit_2()
{
    $services = $this->input->post('serv');
    $data = [];
    foreach($services as $service)
    {
        $data[] = array(
        'service_name' => $service,
        'dr_id' => $this->input->post('d_id'),
        );

     }
        $this->insert_model->service_insert($data);
 }

Your Model

function service_insert($data){
   $this->db->insert_batch('services', $data);  
}

You can use below code in controller

    $servData = $this->input->post('serv');
    if(is_array($servData))
    {
        foreach ($servData as $serv)
        {
            if(!empty($serv))
            {
                $data[] = array(
                    'service_name' => $serv,
                    'dr_id' => $this->input->post('d_id'),
                );
            }
        }
    }
    $this->insert_model->service_insert($data);
