Laravel Eloquent Master Detail result

I'm using Laravel 5.1 Just want to ask how to display ORM master detail when child return no data the the master data is not showing

This is My Master Model

<?php

namespace SpekWeb;

use Illuminate\Database\Eloquent\Model;

    class ProdukGroup extends Model
    {
        public $table = 'product_group';
        public $primaryKey = 'prd_group';

        public function telcoProduct() {
            return $this->hasMany('SpekWeb\TelcoProduct', 'prd_group', 'prd_group');
        }
    }

Child Model

<?php

namespace SpekWeb;

use Illuminate\Database\Eloquent\Model;

class TelcoProduct extends Model
{
    public $table = 'telco_product';
    public $primaryKey = 'tel_prd';
}

And this is My Controller

<?php

namespace SpekWeb\Http\Controllers;

use Illuminate\Http\Request;
use SpekWeb\Http\Requests;
use SpekWeb\Http\Controllers\Controller;
use SpekWeb\ProdukGroup;
use SpekWeb\TelcoProduct;

class ProdukController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $memberPrices = ProdukGroup::with(array(
            'telcoProduct' => function($tpJoin) {
                $tpJoin->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
                $tpJoin->where('charge','>=',0);
                $tpJoin->whereMemType('1'); //variabel
                $tpJoin->where(function($qWhere) {
                    $qWhere->whereKodeKec('ASTAY'); //variabel
                    $qWhere->orWhereNull('cluster_gid');
                });
            },
            )
        )
        ->has('telcoProduct')
        ->get();
        return $memberPrices;
    }
}

I want the master record not showing when I filtered the code within 'with' area, using ->has('telcoProduct) still not working for me. The master record still showing on Blade Views. Is there any trick to solve this problems ?
