Mengaktifkan Captcha di Open Journal System

By default, fungsi captcha dalam sistem Open Journal (OJS) tidak diaktifkan. Seperti halnya yang ada di Jurnal Sistem Komputer. Dengan tidak adanya captcha ini, sistem rentan terhadap spam dan bots, sehingga diinginkan captcha ini aktif.

Untuk mengaktifkan captcha diperlukan gdlib yang harus sudah terinstall di server hosting. Tanyakan ke sistem administrator apakah gdlib ini sudah terinstall atau belum. Selain gdlib, yang diperlukan lagi ada file font. Saya menggunakan FreeSerif.ttf.

Dari cpanel, edit file config.inc.php dan isi setting captcha sebagai berikut:

[captcha]

; Whether or not to enable Captcha features
captcha = on

; Whether or not to use Captcha on user registration
captcha_on_register = on

; Whether or not to use Captcha on user comments
captcha_on_comments = on

; Font location for font to use in Captcha images
font_location = /home/jsiskom/fonts/FreeSerif.ttf

File font FreeSerif.ttf merupakan freefont yang saya dapatkan dari sistem linux di direktori /usr/share/fonts/truetype/freefont. Saya upload ke home direktori di domain tempat ojs diletakkan.
