Three oil palms of tenera type aged 25 years old were logged at
Ara Kuda, Kedah, Malaysia (N536’, E10031’). Total height of
each palm was approximately 12 m and testing logs (2.5 m
long and 36e41 cm in diameter) were taken from the middle
part of the whole log as shown in Fig. 1. The log was stored
under a roof avoiding direct sunlight and rain at the Penang
Campus of Universiti Sains Malaysia. Temperature during the
storage was 28e32 C with humidity of 70e80%.
the sap of felled oil palm trunks. The results clearly show
a significant increase of fermentable sugars in the oil palm
sap occurs during storage of the trunks after logging, indicating
the old and felled oil palm trunks are the promising
feedstock for bioethanol.
