This research aims to determine the characteristics of colour uniformity of roasted robusta coffee beans using image processing based on the roasting level. The treatment factors were analyzed using a completely randomized design (RAL) factorial with 2 treatment factors of roasting coffee bean temperature and roasting time of the coffee beans at 180°C, 200°C and 220°C and the treatment of coffee bean roasting time for 14 minutes, 18 minutes and 22 minutes and the treatment was repeated 3 times. The research used parameters of chemical characteristics (moisture content, ash content and alkalinity of ash) and roasted Robusta coffee bean images using image processing. RGB indeks analysis in image processing of roasted robusta coffee beans only occurs on coffee bean objects and does not occur on the image background. The results showed that the interaction between temperature treatment and roasting time had a significant effect on the quality characteristics of roasted coffee (moisture content, ash content and alkalinity of ash). The interaction of A1B1 treatment yielded the persentage value of decreasing water content, ash content and alkalinity of ash) respectively 5,69 %, 3,21 % dan 58, 26 gr.
