Research about preparing of rubber compound for carpet has been done. The aim of this research to study the effects of natural rubber RSS and CaCO3 as a filler, its physical properties, and also to find out rubber compound for carpet formula in accordance with SNI 12-1000-1989. The compound was produced from natural and synthetic rubber mixture with variation of RSS/SBR 70/30; 80/20; 90/10 phr respectively and the amount of CaCO3 90; 100; 110 phr respectively. The compound was made by using two roll mill machine and than it was tested the physical properties by methods of SNI 12-1000-1989 Rubber Carpet. The physical properties of compound showed that an increasing of natural rubber (RSS I) significant enfluence to increase elongation from 420,00% until 466,66% while hardness from 69,11 shore A until 68,11 sore A, and compression resistance decrease from 580,42% N/cm2 until 523,20 N/cm2. The addition of CaCO3 very significant enfluence to increase hardness from 65,77 shore A until 71,83 shore A, permanent set from 482,32 N/cm2, and the density from 1,48 g/cm2 until 1,55 g/cm2. The physical properties of elongation decrease from 464,44 % until 406,66 % and the aging resistance decrease too (colour changing and cracked). The rubber compound for carpet was produced by using RSS/SBR 80/20 and added CaCO3 100 phr accordance with SNI 12-1000-1989 and significant difference with the others.
