"The format and mechanism of the third and fourth debates will be similar," he said here on Saturday.
Each session will comprise eight minutes, which means four minutes for each candidate. "Each candidate will have four minutes in order to be fair," he said.
In the first session, each candidate will outline his respective vision and mission for four minutes each.
In the second and third sessions, they will respond to questions prepared by panelists and read out by the moderators.
In the fourth and fifth sessions, the presidential candidates will pose questions to each other.
The fourth debate will see the candidates speak about ideology, the government, defense and security, as well as international relations.
The first debate, held on January 17, 2019, centered on law, human rights, terrorism, and corruption. The second debate took place on February 17, 2019, and focused on energy, the environment, infrastructure, food, and natural resources.
The third debate was organized on March 17, and only the running mates participated in the discussion on education, health, manpower, and social and cultural issues.
No date has been set yet for the fifth debate, which will see four of them battle it out on stage over the economy, social welfare, finance and investment, as well as trade and industry.
Indonesia will organize legislative and presidential elections simultaneously on April 17, 2019, across the country.
Of its total population of 260 million, over 192 million people in Indonesia have been registered as illegible voters.
The 2019 presidential election is seen by many as a repeat of the bitter presidential battle of 2014, wherein Joko Widodo (Jokowi) and Subianto went head-to-head.
Seeking a second term, 57-year-old Jokowi has picked Ma'ruf Amin (75), chairman of the Indonesian Ulema Council (MUI), as his partner, while retired general Subianto (67) has chosen Sandiaga Salahuddin Uno (49), a successful entrepreneur and former deputy governor of Jakarta, as his running mate.
