The use of dyes in textile industry has great potential in polluting the environment, particularly due to the remaining dyes in wastewater are very difficult to decompose naturally. This pollution can be reduced by conducting special treatment on textile waste to decrease the dyes level. One of the most popular is the adsorption method. The purpose of this research was to study the adsorption of Remazol Red dye in textile waste by activated carbon synthesized from coconut shell. Activated carbon was given two different treatments: without activation and with activation at 900 °C. The results showed that the activated carbon synthesized had water content of 22.52% (without activation) and 9.49% (with activation). The adsorption of these activated carbons against Remazol Red dye took place optimally at the contact time of 30 minutes by following the Langmuir adsorption isotherm model. The adsorption process occurs homogeneously with the formation of monolayer with a q m value (maximum monolayer capacity) of 226.2 mg/g (without activation) and 250 mg/g (with activation).
