These two signs are at different places along the Tasik Lama to Markucing forest trail. Note the variable spelling of tasik ('lake'): on the left, it has an 'i', while on the right it has an 'e'.
This is rather similar to the variable spelling in the name Abin/Aben that I discussed earlier (here). And it similarly involves variability in the vowel in the final syllable, as the vowel /i/ in a closed final syllable can be pronounced as [e] in Malay.
