The survey, which collected information mainly through interviews, revealed five indicators for arriving at this conclusion.
Indo Barometer's researcher Hadi Suprapto Rusli said the first indicator was that a majority of the people - 64.4 percent - are satisfied with the government's performance compared to 31.6 percent, who are unsatisfied.
"Some 75.2 percent of people are expected to vote for Jokowi as compared to 74.1 percent for the Prabowo Subianto and Sandiaga Uno pair," Hadi told a press conference here Tuesday.
According to him, the second indicator, as revealed by the survey, is that Jokowi has a better personality and capability as compared to Prabowo.
According to the survey, Jokowi has more experience (88.3 percent), is more attentive and closer to the people (86.2 percent).
"Jokowi is smarter (84.4 percent), more capable of leading (77.7 percent), more Islamic or pious (74.5 percent) and more honest (67.8 percent). Prabowo is great at being firm (83.2 percent) and is respected as a big leader (79.9 percent)," he noted.
The third indicator is Jokowi's three card programs initiative, which received a positive response from the people. They are the Card for Cheap Basic Necessities, the Card To Go to Universities and the Pre-Work Card.
"The fourth indicator is that a majority of the Indonesian Muslim respondents believe that Jokowi represents Islam more than Prabowo does. Some 45.5 percent of the respondents say they are in favour of Jokowi and 30 percent of them support Prabowo, while 24.5 percent of the respondents did not answer," he said.
"The fifth indicator is that Jokowi is popular among all segments of voters, including those divided on the basis of gender, villages-cities, islands, religions, ages, education, professions and the coalition supporting parties," he said.
However, he also cautioned that the Jokowi-Ma'ruf pair might not win if 40 percent of voters do not vote and all the supporters of the Prabowo-Sandi pair vote for candidate no 2.
The margin of error in the survey is some 3.83 percent at a credibility rate of 95 percent.
