$(".radio_penerima_kps").click(function () {
    if($(this).val() == "Ya"){
       $("#nomor_kps_pkh").prop("disabled", false);
       $("#usulan_sekolah_layak_pip").prop("disabled", false);
       $("#alasan_layak").prop("disabled", false);
    }else{
      $("#nomor_kps_pkh").prop("disabled", true);
       $("#usulan_sekolah_layak_pip").prop("disabled", true);
       $("#alasan_layak").prop("disabled", true);
    }
});

Answer 1

in case condition fail, change div style. divs can not be enable or disable, only inputs

 $("#form_kps").css('background', "#ccc")

Answer 2

You can change the input associated with the div by using:

$(".radio_penerima_kps").click(function () {
if($(this).val() == "Ya"){
    $('#form_kps .form-control').prop("disabled", false);

}else{
  $('#form_kps .form-control').prop("disabled", true);

}

});

So, you basically use the id of the div and the class associated with it to change the values of the input. There is no way to enable/disable divs.
