The protests followed a day of demonstrations in which 301 people were detained and tear gas and water cannon used to disperse angry crowds outside the House of Representatives building, which on Thursday shelved its controversial plan to amend eligibility rules on candidates, citing absence of a quorum.

The protests were accompanied by fury on social media at the influential Jokowi, who stood to gain from proposed changes that would have allowed his son to seek office in Central Java, and blocked an influential government critic from running for the high-profile post of Jakarta governor.

When asked about the protests, Jokowi said on Friday it is good for people to express their aspirations. 

He said on Wednesday he respected Indonesia's democratic institutions, when asked about the attempt by the House to change the election rules. 

The demonstrations capped a dramatic week in politics in which anger has mounted over what Jokowi's critics say is an attempt to further consolidate his power as he prepares to make way for successor Prabowo Subianto in October.

Jokowi's popularity and outsized influence after a decade in charge was instrumental in Prabowo winning February's election by a big margin, in what was widely seen as a quid-pro-quo to ensure the outgoing leader retains a political stake long after he leaves office. 

Student protester Diva Rabiah, 23, was among hundreds of people who gathered outside the election commission in Jakarta urging it to issue clear rules on candidates, concerned that regulations could be changed before registration opens next week. 

"This bothers me because they eased the way for the president's son to run in the regional elections. This is nepotism," she said of the earlier plan by lawmakers. 

Demonstrations were also held on Friday in the cities of Medan, Makassar and in Surabaya, where students threw rocks and bottles at police, calling for the poll body to issue the rules.

It is unclear what role Jokowi will play when he leaves office, but he is expected to wield influence through the Golkar Party, the largest member of Prabowo's legislative alliance, which on Wednesday appointed president's right-hand man Bahlil Lahadalia as its leader. 

The push by lawmakers to change the election rules would have effectively been a reversal of a Constitutional Court decision on Tuesday, which upheld the minimum age of 30 for candidates, and made it easier for parties to make nominations. 

That ruling opens the door for Prabowo's presidential election rival Anies Baswedan to be nominated for Jakarta governor, a post he held from 2017-2022, but means Jokowi's 29-year-old son Kaesang Pangarep cannot run in regional polls. 

The election commission would issue rules in line with Tuesday's court ruling, but after a consultation with the House next week, its acting chief Mochammad Afifuddin said in a press conference.
