Human Factors
After push and disconnect; the towbar came loose from the tug. At that time; I was in the middle of the after start flow and left the APU on. It was not noticed until later in the flight. This in turn led to Maintenance write-up due to fuel totalizer disagreement which was caused by the APU fuel burn enroute.
B767 First Officer reported Auxiliary Power Unit was left running during flight resulting in higher fuel burn.
