Abstract

Abundant chicken feet skin waste remains underutilized despite its potential as high value exotic leather due to its unique natural scale patterns. This study was aimed to evaluates the utilization of broiler chicken feet skin through eco-friendly tanning by using local vegetable extracts: Sappan wood (Caesalpinia sappan), Acacia wood (Acacia sp.), and tea leaves (Camellia sinensis), with commercial textile dye as a control. A completely randomized design with four treatments and three replications (h=3) was employed. Raw material analysis revealed a proximate composition favorable for collagen-based tanning, dominated by a crude protein fraction of 25.67 ± 0.58. Results indicated that tanning agents significantly affected (p< 0.05) physical and mechanical properties. The highest thickness was observed in the Acacia treatment (0.54 ± 0.01 mm). While the control exhibited the highest tensile strength, Acacia yielded the highest strength among vegetable groups (1860.17 ± 10.00 N/cm²) but recorded the lowest elongation (19.68 ± 0.25%), indicating increased tissue stiffness. Tea leaf extracts produced the highest tear resistance among vegetable treatments (300.81 ± 0.20 N/cm). Scanning Electrone Microscope (SEM) confirmed consistent differences in porosity and micro cracking across treatments. These findings confirm that local vegetable tanning is a viable waste to resource strategy for producing sustainable, premium oriented alternative leather
