I mentioned two things to improve your factory during last visit.
I checked your corrective action plan and I have something to comment again.
Regarding high bale temperature, if you can control the inverter system well, your action plan should be effective.
But for contamination, in my opinion, main problem comes from raw material.
In your corrective action plan, there is no comment about that.
Your contamination level in normal condition is similar as other factories in Palembang.
But when I visited your factory, you were using raw material from near Jambi area.
If you use dirty raw materials, then my concern is you cannot remove contamination with your corrective action.
It will bring out contamination issue in my plant.
I hope you to find solution for raw material.
