Don't want custom posts on blog page

I’m using Simple Custom Post Type to build this page:
http://www.demo.shalomcpp.com/tribe/

I have the standard blog page here:
http://www.demo.shalomcpp.com/news/

This is a child theme of TwentyEleven.
I don’t want the posts from Tribe page to show on the News(blog) page.
I prefer to code this instead of assigning any categories to separate them.
