The objective of the research is to use minarex, by product of Pertamina, as a softener in making rubber sole compound for canvas shoes. The formula of the compound applied four kinds of minarex, manely minarex A, B, C and D with variation 2 ? 8 phr. The mastication and mixing processes used two roll mill machine and the compound was vulcanized at 150 oC, at the pressure 150 kg/cm2and 10 mnutes curing time. The comformityt of softener, minaret, is excellent and no oil exist to the surface of the vulcanized compound. The property of the vulcanized compound fulfilled all the quality requirements of SNI 0778-89- A and SNI 1844-90-A for canvas shoe rubber sole, except abrasion for sport shoe (max. 1.00 mm3/ kgm compared with the result of the test, 1.52 ? 2.35 mm3/kgm). Data analysed proves the to kinds of minarex to influence all properties in rubber compounds. While treatment of minarex to inflience the properties of elongation at break, permanent set and hardness. The type of minarex to influince properties of the tear strength, abrasion and density to rubber compound.
