<script type="text/javascript">
  function ganti(nama){
    var lokasi = '../bab2/images/' + nama + '.png';

gusion and selena are names… specifically, they are variable names.

If you want a string then you need to surround it with quotes.

If you want to pass names as parameters you need to pass them as Strings, i.e., enter the name within quotes. Here is the modified code:

<a href="#" onclick="ganti('gusion')">1</a>
<a href="#" onclick="ganti('selena')">2</a>
