A rough idea. This assumes you have learnt the L’ Hopital Rule, but I don’t recall this appearing in H2 Maths at all.

lim
x --> 0+
means "as x approaches zero from the positive side".
Even though ln 0 itself is undefined, we see that x decreases to a very low positive value (approaching zero), ln x approaches a very negative infinite value. We only have a limit to 0+ because the limit at 0 itself is not exactly defined.

He is just picking the H2 Math topic because there is no category for polytechnic math.
A cursory look at his profile shows Singapore Polytechnic. So this is likely to be from a poly module.
Edit :
One question in the question history shows MA1301, which I answered in the comments section.
That is the module code for Introductory Mathematics in NUS (so possibly a uni student too).

By the way, it is 0+ not because the limit at 0 is not exactly defined.
It's more of a case of not being able to approach the limit from 0- because the function isn't defined for x < 0
