Abstract

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.

Abstract

Gambier is obtained from the extraction of leaves and young twigs of Uncaria gambir, a shrub that grows in Indonesia. Gambier contains tannin by 20% to 55% so that can be used as a vegetable tanning material using the C-RFP system (C=Conditioning, R=Rapid, F=Fass (drum), P=Powder). This research aimed to determine the effectiveness of gambier as a vegetable tanning material using the C-RFP system. Pickled leather underwent a tanning process using the C-RFP system with gambier as the tanning material at various percentages, namely by 15%, 20%, and 25%, to be processed as leather for jackets. The variations of oil used to keep the leather supple were 12.5%, 15%, and 17.5%. The tanned leather was then tested in terms of its organoleptic, physical, chemical, and morphological properties. Results of the organoleptic test and most of the results of the physical test showed that leather for jackets which was tanned using a vegetable tanning material met the requirements set out by SNI 4593: 2011 (sheepskin/goatskin leather for jackets). Results of the SEM test indicated that leather for jackets which was tanned using a vegetable tanning material displayed dense and strong skin tissue, and this proves that gambier is very effective for vegetable tanning using the C-RFP system.Keywords: C-RFP, gambier, vegetable tanning, environmentally friendly.
