This is entirely a temperature issue, and very likely related to your bed temp keeping the bottom of your part too hot/soft. HIPS is a bit, finicky, and you definitely want to print at the lowest nozzle temp you can while still getting good extrusion. Start by tweaking your bed temp. Personally I print the first few layers at 110, then after about .5mm drop the bed temp to 100. Some sources will tell you to go as low as 90-95 so you can experiment with that, but I’ve found I lose adhesion that low. You can also play with your fan speed. I’ve found that with HIPS a range of 40-60% works pretty well. Most importantly though, make any changes to your settings one at a time, and document what’s happening so you know exactly which setting is having what effect.
On a side note, you also seem to be getting a lot of banding from z-wobble. You might check out this post
