First of ALL login to your Facebook account which you want to change.
Now go to your browser network setting. There are lots of browsers but I will recommend you to use Firefox in pc and UC FOR MOBILE for this purpose. In Mozila Firefox go to Tools> Options > Advanced > Network > Settings. You will find out this option bar from the top of your browser.
Now select manual proxy and put “126.96.36.199″ in the proxy address and “8080″ in the port address. And make sure to check the box said, “use this proxy server for all protocols”. You should be logged in to your account before changing proxy. Because sometime you may can’t login to your account. Please note that, this is not a specified proxy. You can use any others as you wish but the proxy should be Indonesian. You can get many proxies from here Indonesia Proxies. This is the main process to have a Facebook without last name. For more check out the screenshot from below:
Now change the language of your Facebook account to “Bahasa Indonesia”. For that click Gear Icon > Account Settings > Languages. After changing save the setting.
Now click on the Name setting from the account settings page. Then just remove the last name and save name with your password. Make you sure that, in this way you can only use the first name as your full name. So, if you want a different name from your full name, first change the first and last name and keep your selected name in the first name section. Now in this method, delete the last name and make one word Facebook name. At the last save and YOU WILL HAPPY TO SEE THAT YOUR NAME HAS BEEN CHANGED TO STYLISH NAME.IF LIKE SHARE it.
