The objective of the research was to study the effect of number of water of Cr2O3 absorbtion in chrome tanning for goat skin and to reduce utilization of water and chrome waste and to optimize function of Cr2O3. Waste water of pickle were used in variation of 20, 40, 60% respectively and control was also mode as comparation. Twenty pieces of green salted goat skin were grouped and devided into four groups and every five pieces were treated five pieces. The applications parameters of quality were determined including Cr2O3 absorbtion, shrinkage temperature, tensile strength, elongation at break, stitch strength and tear strength. The results showed that the number of Cr2O3 absorb and shrinkage temperature in this research was significantly added water effected on tanning process. The pickle water of 40% performed optimal chrome tanning for goat skin in the amount of 3.13% Cr2O3 absorbtion ; 115.38 0C shrinkage temperature; 216.58 kg/cm2 tensile strength; 43.14% elongation at break; 64.77 kg/cm2 stitch strength; 27.46 kg/cm2 tear strength and all of quality parameters fulfill the requirements of Indonesian National Standard (SNI) 06-117-1989 about Quality and Testing Method Goat Skin Glace.
