| dc.description.abstract | Mangrove wood is known to have a high calorific value; therefore, it has
traditionally been used as a source of firewood by our ancestors. Continuous
exploitation has caused mangrove forests to degrade and their ecological functions
to diminish. For this reason, this study utilizes only the branch parts of mangrove
wood to ensure that mangrove forests remain preserved and sustainable.
Furthermore, this research focuses on diversifying energy sources. Previous studies
have produced briquettes, pellets, charcoal, and charcoal briquettes from
mangrove wood branches. A byproduct of charcoal conversion is bio-oil, which can
also be used as an energy source. In this study, three types of mangroves, namely
black mangrove (Rhizophora mucronata), tancang (Bruguiera gymnorrhiza), and
mata buaya (Bruguiera sexangula), were pyrolyzed to produce charcoal and bio
oil. The bio-oil was characterized to evaluate its contents and subsequently
recommend potential uses. Characterization results included yield, viscosity, pH,
and chemical properties using GC-MS analysis. The results showed that R.
mucronata had the highest viscosity of 1.9 and contained the most variations of
compounds, with 12 chemical components. B. gymnorrhiza had the highest pH of
3.94 and contained 8 chemical components. B. sexangula had a viscosity of 1.9 but
only contained 2 compound components. Further research should be conducted for
the feasibility as energy source. | en_US |
