   <tr>
      <td>{{ $produk['nama_produk']}}</td>
      <td>{{ substr($produk['deskripsi'], 0, 130).' . . .' }}</td>
      <td>
         @foreach ( $spesifikasi as $spek )
             {{ $spek['title_spek'] }} : {{ $spek['spek'] }} ||
         @endforeach
      </td>
      <td><img src="../{{ $produk['display_thumb'] }}"></td>

update Armen Markossyan

this is my model
Produk.php

<?php
    class Produk extends Eloquent {
    protected $table = 'produk';
    protected $primaryKey = 'id_produk';
    protected $fillable = array('id_produk', 'nama_produk', 'deskripsi', 'display_thumb');

    public function SpesifikasiProduk() {
        return $this->hasMany( new SpesifikasiProduk, 'id_produk');
    }

    public function ImageProduk() {
        return $this->hasMany(new ImageProduk, 'id_produk');
    }
}

SpesifikasiProduk.php

<?php
class SpesifikasiProduk extends Eloquent {
    protected $table = 'produk_spek';
    protected $primaryKey = 'id_spek';
    protected $fillable = array('id_produk', 'title_spek', 'spek');

    public function produk() {
       return $this->belongsTo('Produk');
    }
}

and i already change to become like this

My Controller

public function getDashboard() {
    $produk         = Produk::with('SpesifikasiProduk')->all();
    return View::make('admin-page.admin-produk')
                -> with('produk', $produk );
}

My View

 @foreach ( $produk as $produk )
     <tr>
         <td>{{ $produk['nama_produk'] }}</td>
         <td>{{ substr($produk['deskripsi'], 0, 130).' . . .' }}</td>
         <td>
             @foreach ( $produk->SpesifikasiProduk as $spek )
                   {{ $spek['title_spek'] }} : {{ $spek['spek'] }} ||
             @endforeach
         </td>
 @endforeach

but i still get error like this

Call to undefined method Illuminate\Database\Query\Builder::all()

You have to read about relationships: http://laravel.com/docs/master/eloquent-relationships#defining-relationships

Read your own words: "one produk have many spesifikasi". This means that you can establish a "hasMany" relationship between Produk and SpesifikasiProduk.

Do it like follows:

// Produk model
<?php

namespace App\Models;

class Produk extends \Eloquent {

    public function spesifikasi()
    {
        return $this->hasMany(new SpesifikasiProduk, 'id_produk');
    }

}

Your controller code:

public function getDashboard() {
    $produk = Produk::with('spesifikasi')->get();
    return View::make('admin-page.admin-produk')
                -> with('produk', $produk);
}

Your view:

@foreach ( $produk as $produk )
   <tr>
      <td>{{ $produk['nama_produk']}}</td>
      <td>{{ substr($produk['deskripsi'], 0, 130).' . . .' }}</td>
      <td>
         @foreach ( $product->spesifikasi as $spek )
             {{ $spek['title_spek'] }} : {{ $spek['spek'] }} ||
         @endforeach
      </td>
      <td><img src="../{{ $produk['display_thumb'] }}"></td>
@foreach

Good luck!

UPD:

There are many ways to perform what you want.

The easiest way is to use @for instead of @foreach:

@for ($i = 0; $i < 2; $i++)
    {{ $product->spesifikasi[$i]['title_spek'] }} : {{ $product->spesifikasi[$i]['spek'] }} ||
@endfor

Of course, you have to remove take(2) from the model.
