Abstract—This research aimed to study the quality of the fuel
briquettes made from sewage sludge mixed with water hyacinth
and sewage sludge mixed with sedge. Sewage sludge were
mixed with water hyacinth and sedge at the ratios of 1:1,
1:2, 1:3, 2:1 and 3:1 then compressed these mixtures with
hydraulic pressure to obtain fuel briquettes and finalized
them by analyzing fuel briquettes properties including
moisture content, calorific value and compressive
strength, then comparing them to the properties of the wood
charcoal standard. The result showed that the ratio of
wastewater sludge and sedge at 1:3 provided the highest
calorific value (3,362.9 cal/g) but still lower than the
standard (5,000 cal/g) and the ratio of wastewater sludge
and water hyacinth at 1:3 gave the highest compressive
strength value (4,545 N). And the moisture content of them
was between 4.78% and 7.86%.
Index Terms—Sewage sludge, water hyacinth, sedge, fuel briquettes.
