You have to use nested array to match check the validation.

  var account = [
    {'ID': 2,'nama': 'test'},
    {'ID': 3,'nama': 'test1'},
    {'ID': 4,'nama': 'test4'},  
    {'ID': 5,'nama': 'test5'},
  ];
  var account_selected = [
    {'ID': 2,'nama': 'test'},
    {'ID': 5,'nama': 'test'}
  ];

  $.each( account, function( i, valueAccount ) {
    var dataAccount = valueAccount;

    $.each( account_selected , function( i, valueSelected ) {
      var dataSelected = valueSelected;
      var temp = '';
      if( (dataSelected.ID == dataAccount.ID) &&  (dataSelected.nama == dataAccount.nama) ){
      temp += '<option selected  value="'+dataSelected.ID+'" id="account_id'+dataAccount.ID+'" value="'+dataAccount.ID+'" >'+dataAccount.nama+'</option>'
      }else{
      temp += '<option  value="'+dataAccount.ID+'" id="account_id'+dataAccount.ID+'" value="'+dataAccount.ID+'" >'+dataAccount.nama+'</option>'
      }
      console.log(temp);
    });
  });
