Indonesia, on their part, looked to hit on the counter-attack but failed to really trouble the Philippines backline.
Philippines doubled their lead in the 27th minute when Sarina Bolden outjumped her markers to head home.
The lead could have been wider but for Aprilia, who pulled off save after save to keep Indonesia within distance.
The Indonesian backline, however, were unable to cope with the Philippines pressure and in the 56th minute, a poor clearance allowed Tahnai Annis to convert the loose ball with a crackling strike into the bottom right corner.
Philippines were awarded another penalty in the 73rd minute after Amiatun's foul on Dominque Randle, and Jessica Miclat made no mistake to make it 4-0.
Annis double her personal tally in the 83rd minute with a scorcher from 20 yards out and Malea Louise Cesar sealed the emphatic win with her goal in the fourth minute of added time.
