Natural dyes from mahogany are usually obtained by conventional extraction. This extraction process requires a large
solvent, a long duration of the process so that the energy requirements are also higher. Therefore, the use of "green
techniques" to extract natural dyes with a minimum of energy and solvent should be considered. One extraction
method that has been developed is the microwave-assisted extraction (MAE) method. In this work, the effects of microwave
power, material to solvent ratio, and the heating time on the extraction results and the pigment components
of the extract were examined. A comparison of the time required for reflux extraction and Soxhlet was also made. In
microwave extraction, the highest yield was obtained at optimum extraction conditions such as microwave power of
600 W, the ratio of material to solvent of 0.02 g/mL, extraction time of 30 min. While for reflux and Soxhlet extraction,
the extraction time needed to obtain optimum yield was 120 min and 720 min, respectively. Identification of compound
components by the phytochemical test. Descriptions of the effects of microwave and conventional extraction
are shown by damage to the surface structure of solid materials using Scanning Electron Microscopy (SEM).
