removing comments sections

Removing the comments section from pages on my blog. I’ve been trying for a while. I did the whole edit page –> screen options –> comments (unchecked)

but it only removed the comments section from the edit pages screen not from the actual published page.

These are the specific pages I want to remove the comment section from:
http://arirangradio.wordpress.com

and
