ABSTRACT
At the end of the twentieth century, experts realized the impacts of the increasing use
of pretrolium when its supply inevitably decreased. Cinnamon and other wood types
such as alaban and candlenut are known as the wood types that are good enough to
be used as the raw materials for charcoals. The objective of this study was to find out
the quality of charcoals made from cinnamon wood, candlenut shell, alaban wood,
and acacia wood in their capacities to produce energy primarily for domestic use.
The method was to compare the capacity of 1 kg of charcoal with the capacity of 1
liter of kerosene poured into the Hock stove with 16 wicks to produce energy. The
tests were carried out at the Laboratory of the Institute for Research and
Standardization of Industry, Banjarbaru. The analysis of the respective physical and
chemical properties of the charcoals indicated that the water contents of cinnamon
wood, candlenut shell, alaban wood, and acacia wood charcoal were 0.66%, 1.15%,
0.69%, and 0.61%; ash 2.37%, 3.62%, 2.57%, and 0.48%; volatile matter 23.94%,
35.35%, 29.65%, and 42.61%; fixed carbon 73.69%, 61.03%, 70.48%, and 56.91%;
and calorific value 7591.84 cal/g, 5649.70 cal/g, 7008.59 cal/g, and 6280.76 cal/g.
After burned, the cinnamon wood charcoal gave the highest maximum temperature of
235°C with the burning duration of 50', alaban wood 216°C with the burning
duration of 1 hour 10', acacia wood 195°C with the burning duration of 1 hour 8' and
candlenut shell 175°C with the burning duration of 36'. The time required to boil 1
liter of water for cinnamon wood charcoal was 5', alaban wood 6'30", acacia wood
7'30", and the candlenut shell 8'59". When compared with the use of kerosene for
Hock stove with 16 wicks, and converted into economic value, the 3 types of wood
charcoals, namely cinnamon, alaban and acacia wood charcoals can be used as the
alternative energy sources.
