The main things to keep in mind are:
- The two control points for flash exposure are aperture and power
- Since aperture also affects ambient light exposure, power is probably the more useful
- Unless the flash is very powerful, at moderate distance and moderate power and moderate ISO one may reasonably choose a moderate aperture
Here is an example for your 44 AF-1 with guide number 44 (meters) at full power.
At 1/16 power* and ISO 200 and 3m distance, an aperture of f/8 should work well.
If f/5.6 would work better, set power to 1/32. I hope this helps.

(...did not try those settings...hoping the calculation is close...usually just sort of fudge my manual flash work...)
* 1/16 power on the 44 AF-1 is about guide number 17 which is a bit lower than that of the moderately powerful Pentax AF201FG.
