It appears to be under extruding. Did you calibrate the extruder? When you calibrated it, did you do it at 100 um layer thickness? Did you do the fine calibration outlined here: [reprap.org] ?
Did you measure the filament diameter before printing? If the filament is smaller in diameter than the slicer thinks, you'll have under extrusion. Don't trust the manufacturer's nominal diameter value!

Calibrating extruder did. Using abs filament 1.75 diameter. Possibly can in settings slic3r.

Did you try different temperatures? Try 10 degrees higher and lower than your current temperature and see if it improves.

I know the manufacturer's packaging says the filament is 1.75mm diameter, but did you measure it? Measure the diameter with a caliper that reads down to 0.01 mm at at least 20 places, varying the orientation of the caliper on the filament as you do, and calculate the average filament diameter. Mark that diameter on the spool's label and use that value when you slice or print. If the filament is smaller than 1.75 mm, you will see underextrusion if you tell the slicer the diameter is 1.75 mm.

My problem calibration e steps extruder. Using MK9 extruder. My settings now e steps = 101.0869. Help calibration extruder please.

Thank you for all the help. Now calibration E steps = 48.8 mm/s for MK9 extruder.
