Codeigniter URL Routing Issue

Question

I'm new to codeigniter and want to set my URLs on website currently I'm using version 3.0.1 URL looks like

http://oti.nhmp.net/index.php/site/about_us

I want it like this

http://oti.nhmp.net/about_us

i have tried URL routing in routes file but it's not working for me here is the code

routes.php

$route['default_controller'] = 'site';
$route['about_us'] = "index.php/site/about_us";
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

.htaccess

<IfModule mod_rewrite.c>

    RewriteEngine On
    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to 
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]    

</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin
