the graph you just copied above concerns the flight Bali-Jakarta that precedes the accident flight.
The graph for the accident flight is this one:
You can see that, for the first part of the flight, there a mix of trim up and down commanded by the automation (I guess it means "by the STS"), with also some pilot trim inputs.
After one third of the flight, there is a regular pattern of alternating trim down from the automation with trim up from the pilot.
Until the very end where the pilot input becomes short pulses that are insufficient to counteract the automation longer pulses.
The graph from the previous flight also shows a mix of frequent pilot trim up and PA trim down, up to a point where it stops, restarts a bit later, and then stops for the rest of the flight.
