Coffee is one of the plantation products with high economic value and can be used as a strategic commodity for developing the country's economy. However, the coffee ground waste contains organic compounds that are harmful to the environment. The use of coffee grounds waste as a carbon material precursor has been widely carried out because coffee grounds have a fairly high carbon content. In this study, coffee grounds from pyrolysis produced graphite coffee grounds. The resulting coffee grounds graphite is then used as the main precursor in the modification of graphite into graphene nanosheets using the liquid exfoliation method with the help of surfactants, where in the process, two types of surfactants were used, namely anionic (SDS) and cationic (CTAB). The modified graphene nanosheets were then characterized using Raman spectroscopy, XRD, and SEM. Raman spectroscopic characterization results proved that there is a change in intensity in the D and G bands, which indicates a change in the structure of the graphite material. The SEM characterization results showed a morphological change from the amorphous structure of graphite to a thin layer as in graphene. BET analysis was carried out and showed a change in the sample's surface area and pore size. The application of Graphene nanosheets produced on the adsorption of Rhodamine B compounds showed an increase in adsorption before modification and after modification to graphene, which was originally 18.74 % at 5 ppm to 54.14% (G-25 Coffee/SDS), 22.67% (G -25 Coffee/CTAB).), 76.17% (GS Coffee/SDS), and 66.56% (GS Coffee/CTAB).
