Hi kblubis
You're using 'Simple' theme of JA Good so you can open the file:
/templates/ja_good/tpls/blocks/header/header_simple.php
Look for this code:
<a href="<?php echo JUri::base() ?>" title="<?php echo strip_tags($sitename) ?>">
and change the href="<?php echo JUri::base() ?>" attribute to URL as you wish.
Like:
<a href="https://v1.bakrie.ac.id/" title="<?php echo strip_tags($sitename) ?>">
