Characteristics of Tanning Leather Using Gambir on pH 4 and 8
Tannery production process in Indonesia is still using chromium sulfate or mimosa in general. Gambier (<em>Uncaria gambier</em> Roxb.) extract could be used as material for tanners because it contains tannin. This study aimed to investigate the characteristics of tanned leather using gam...

This study aimed to investigate the characteristics of tanned leather using gambier solution at pH 4 and 8. Standard tanning method was used which includes the processing of goat leather with salt, acid and then tanned with gambier extracts. Observation of tanned leather refers to the SNI-06-0463-1989-A and ISO 0234:2009.
