Answer 1

Try this(change out vg.no with what you want):

<div href="https://www.vg.no" onclick="openInNewTab('https://www.vg.no')">Something To Click On</div>
    <script>
        function openInNewTab(url) {
            var win = window.open(url);
        win.focus();
        }
    </script>

Answer 2

You should get value from record like:

 {
     text: 'Berkas',
     align: 'center',
     cell: {
         xtype: 'button',
         dataIndex: 'file_kp_prodi_mhs',
         text: 'View',
         handler: function(button, e) {
             window.open(e.record.get(button.dataIndex));
         },
     }
 }
