Praneeth, who won the Singapore Open in 2017 and finished runner-up at Swiss Open earlier this year, came into the tournament with a 1-2 head-to-head count against the Indonesian.
In the opening game, he raced to a 8-4 lead, but Jonatan stepped up and drew parity at 10 before Praneeth took a 11-10 advantage at the break with the help of a delicate shot at the net.
The duo continued their battle after the breather as Jonatan kept breathing down the Indian's neck.
Praneeth eventually grabbed game point at 20-19 with a cross-court smash at the back, but Jonatan turned tables and enjoyed a game point himself.
However, Praneeth ensured he had the last laugh, unleashing a powerful smash, which the Indonesian returned wide. Then his rival's weak return got buried into the net.
Praneeth missed the shuttle at the backline to concede a point but grabbed the required two points -- the last one with a cross-court smash -- to pocket the opening game.
The second game turned out to be one-way traffic as Praneeth came out with all cylinders blazing, first surging to a 7-1 lead, and then a massive 11-3 advantage at the break.
Jonatan narrowed the gap to 12-15 but the Indian stepped up to grab six match-points, punishing a weak return and then shutting the door on Jonatan, who went wide.
