Making Sidebar Show in…

Hello, I wish for someone to help me in making my WordPress Sidebar work in PHP files that are not pages made within wordpress.

Example of what I mean:
http://para-rabu.org/collective.php

I’ve been trying various things and I haven’t been able to make it work myself. If anyone can help me it would be greatly appriciated.

Here is a page I’ve been tinkering with:

Thank you,
