On Service side pls check
1. u have to add

[System.Web.Script.Services.ScriptService]

before web service class to enable service access from script
2. add this before web service method

[ScriptMethod(ResponseFormat = ResponseFormat.Xml)]

to specify the out put format
3. better return Data as xml instead of DataSet

On Client side

$.ajax({
         url: WS_URI,
         type: 'POST',
         data: "Makat="+ MAKAT,
         dataType: "xml",
         success:
           function (data) {
             var item=$(data).find('Item').text();
             var des=$(data).find('Des').text();
           },
         error:
           function (errorThrown) {
            alert(errorThrown);
            }
        });
