Jakarta. University of Indonesia post-graduate student Boby Febry Krisdiyanto apologized to the university and public on Tuesday (06/09), after a video using discriminative and provocative language slamming incumbent Jakarta Governor Basuki "Ahok" Tjahaja Purnama went viral on YouTube earlier this week.

In the video, Boby, who claimed to be a member of UI's chapter of nationwide student Islamic group Gema Pembebasan and wore the university's yellow jacket, advised Jakarta citizens not to vote for the incumbent Basuki in the next year's city election using several discriminative words.

“Ahok is not merely an infidel, but he also oppresses the people. He failed to resolve the poverty and unemployment in Jakarta,” Boby said in the video, adding the governor was also implicated in several graft cases, including Sumber Waras Hospital land procurement and Jakarta Bay reclamation.

The video was filmed in front of the rectorat building on campus at the University of Indonesia.

“I urged the people not to vote for Ahok and replace [the current governance system] with a new political system, which are sharia and khilafah,” Bobby spoke in the video, referring to a governance based on Islamic ideology and the Koran.

Following the circulation of the video, Boby apologized to the rector in a letter with a legal stamp — known locally as materai and used as document legalization — admitting he used University of Indonesia property for political purpose without permits.

University of Indonesia spokeswoman Rifelly Dewi said the circulated video was illegal and did not represent the university.

She added Boby had violated the student ethics regulation which says: "the people of University of Indonesia are prohibited to discriminate others in base of their religion, ethnicity, gender, sexual orientation, political orientation and physical disability.”

“The University of Indonesia, as an educational institution, respects individual rights and gives freedom of expressions to all academics in the university, but it should be followed with obedience to the rules and orders,” Rifelly said.

The university also called on academics to keep political practices away from the campus, Rifelly added.
