                    $("#tabstrip").kendoTabStrip();
  
                    if($('.k-button').is(':visible')){
                        $(this).css("opacity","0.2");    
                    }else{
                        $(this).css("opacity","1");  
             
                }
                });
            </script>

Your code if($('.k-button').is(':visible')) is not working because the left and right buttons are added dynamically.

For the right button, try this code:

$(document).ready(function () {
            $("#tabstrip").kendoTabStrip();
            setInterval(function () {
                var el = $('.k-tabstrip-next');

                if (el.css('display') == 'none') {
                    el.css("opacity", "0.2").css('display', '');
                    el.attr('data-el', 'stop');
                }
                else if (el.attr('data-el') != 'stop')
                    el.css("opacity", "1");
            }, 200);

            $(document).on('click', '.k-tabstrip-prev', function () {
                $('.k-tabstrip-next').attr('data-el', '');
            });
        });

If you want both buttons to be visible, you can try this:

$(document).ready(function () {
            $("#tabstrip").kendoTabStrip();
            setInterval(function () {
                var ne = $('.k-tabstrip-next');
                var pr = $('.k-tabstrip-prev');

                if (ne.css('display') == 'none') {
                    ne.css("opacity", "0.2").css('display', '');
                    ne.attr('data-el', 'stop');
                }
                else if (ne.attr('data-el') != 'stop')
                    ne.css("opacity", "1");

                if (pr.css('display') == 'none') {
                    pr.css("opacity", "0.2").css('display', '');
                    pr.attr('data-el', 'stop');
                }
                else if (pr.attr('data-el') != 'stop')
                    pr.css("opacity", "1");


            }, 200);


            $(document).on('click', '.k-tabstrip-prev', function () {
                $('.k-tabstrip-next').attr('data-el', '');
            });


            $(document).on('click', '.k-tabstrip-next', function () {
                $('.k-tabstrip-prev').attr('data-el', '');
            });
        });
