The purpose of this study was to determine the effect of the use of mimosa, to manufacture environmentally friendly leather for jacket by using the C-RFP system (C=Conditioning, R=Rapid, F=Fass (drum), P=Powder), on physical, organoleptic, and morphology properties of leather. It was also to obtain a formula for vegetable tanning with C-RFP system. Pickled skins are conditioned (pre-tanning) using Sodotan TSN and Sodotan APR, and then Sodotan TSN was chosen due to it meets the requirements of SNI leather for jacket (SNI 4593:2011). Then, pickled skins were tanned with mimosa and applied C-RFP system or rapid tanning without water added. Mimosa, used in this research, were 15%, 20%, and 25% and fatliquor were 12.5%, 15%, and 17.5%. Furthermore, The leather were finished into an environmentally friendly leather for jackets, and then tested for physical and organoleptic properties based on the SNI 4593:2011 as well as leather morphology (SEM). The physical test result shows that for mimosa 15%, 20% and 25%, and for fatliquor 15% and 17.5% are fullfill the SNI.
