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%
