The result, which came courtesy of first-half strikes from Azamuddin Akil and Mahalli Jasuli, was enough to send Harimau Malaya through to the semi-finals, although they had to settle for second place after Singapore wrapped up top spot with a 4-3 triumph over Laos.
Malaysia entered the game with their destiny in their own hands as they knew picking up three points would be enough to send them through to the last four, and Rajagobal believes the way they started the game was key in getting the result.
"It was not an easy match but we started brightly," he said. "The two goals in two minutes was the turning point.
"They were important but Indonesia kept fighting. The players did well in the first half, and in the second half I told them we needed to score one more to end the match.
"But anyway, we are through to the semis."
One of the brightest sparks for Malaysia so far has been 21-year-old Wan Zack Haikal, who has been a real threat for them down the flanks.
However, his boss isn't keen on him getting ahead of himself and believes he must add consistency to his game.
"I started Zack on the left today [Saturday] after missing [S.] Kunanlan to injury," Rajagobal added. "After 15 minutes or so, I instructed Azamuddin and Zack to change positions.
"Both of them played offensively, but what's important is for them to be consistent.
"It's the first AFF Suzuki Cup for Zack and I think he has started well. I hope he will maintain his performance."
Next up for Malaysia is a mouth-watering clash against three-time champions Thailand, who were the only team with a 100% record from the group stage after wins over Philippines, Myanmar and Vietnam in Group A.
Nonetheless, Rajagobal was defiant when asked if he though Winfried Schafer's charges were favourites for their clash.
"This time Thailand have a very good team," he said. "They are fast and work as a unit.
"But like I said, there are no favourites when it comes to the semi-finals. Now I want the boys to recharge and play at a higher level when we meet Thailand."
Malaysia are aiming to become the third side to retain the Suzuki Cup after Thailand and Singapore achieved the feat with their triumphs in 2002 and 2007 respectively.
