Your save method should looks like:

function save(){    
    //echo "<pre>";
    //print_r($this->input->post()); //first try to check whether you are receiving posted data or not.
    //die;

    $id_c= $this->input->post('id_c');
    $idb = implode(',', $id_c);
    $tanggal = $this->input->post('tanggal');
        $data=array(
                    'id_c'=>$idb,
                    'tanggal'=>$tanggal
                    );
        $this->db->insert('detail', $data);
}
