Try this.

@if(is_array(old('bidang')) && in_array('Penelitian', old('bidang'))) checked @endif

Answer 2

Try this

@if(is_array(old('bidang')) && in_array('Pendidikan', old('bidang'))){{"checked='checked'"}}@endif

HTML

<div class="checkbox">
  <label>
  <input type="checkbox" name="bidang[]"  value="Pendidikan" @if(is_array(old('bidang')) && in_array('Pendidikan', old('bidang'))){{"checked='checked'"}}@endif>Pendidikan
 </label>
  </div>

$array = [
 "id" => 3,
 "bidang" => "Pendidikan,Pengabdian Masyarakat,",
 "created_at" => null,
 "updated_at" => null,
 ];

 $bidang = explode(',',$array['bidang']);

 if(in_array('Pendidikan', $bidang)){ 
     echo "something";
     }
