From what you have posted it is the drive side crank + pedal? which as others have said is a normal right handed thread – so anti-clockwise to undo.
I would take the crank arm off the bike first.
Proper pedal spanner is best – but as you said it is AK only – so no good.
Again you need to get an AK socket bit + wrench.
You then need to carefully place the crank in a soft jawed vice or similar (those B&D Workbenches are also good). The idea is not to clamp the crank very tightly but just to stop it turning while you try to loosen the pedal. Probably best to take the chainrings off as they sometimes get in the way or at least cover them up as they are very good at slicing through skin if your hands slip!
