This research aims to obtain the optimal concentration in the variations of natural dyes and examines the characteristics of the resulting rubber compound. Research and laboratory testing conducted at Balai Riset dan Standardisasi Industri Palembang and PT. Kobe Internasional Mandiri Bandung. This study used dye concentration in 5 phr and 4 (four) color variation that were Formula A: Flour mangosteen peel, Formula B: Meal turmeric, Formula C: Flour wooden cup and Formula D: Synthetic dyes as the control. Parameters observed were Hardness, Shore A (ASTM D 2240-1997), tensile strength, kg / cm 2 (ISO 37, 1994), elongation at break (%), 50 PPHM ozone resistance, 20%, 24 h, 40 ° C and total color difference. The results showed that the best treatments was formula C: Flour wooden cup with Hardness test results of 44 shore A, the voltage dropped by 129 kg / cm 2, Elongation at break of 845%, the ozone resistance of rubber compounds showed no cracks and the total color difference was 26,74
