I don't have a P28 POH handy, but maybe it gives 60 knots as approach speed not 'touchdown speed'?
Your actual speed at the point of touchdown, after properly rounding out, should be just above stall speed, which would I guess be about 45-50 knots in a lightly loaded P28 (sorry, my memory is a bit vague, it's some years since I flew one). If you touch down 10-15 knots faster than this, you deserve to, and probably will, go merrily bouncing down the runway. (edit to say, just like PilotDAR's clip above)
But the main point is, why on earth are you looking at the ASI as you round out? Eyes ahead to the end of the runway...
Don't understand the bit about thatched roofs, is that a Malaysian custom?
PB - by all means read the POH, but please fly the aircraft, not the numbers...
