Leather products are parts of daily fashion in Indonesia, such as bags, shoes, jackets, and gloves. Adulteration of raw materials for leather products can occur if there are no labels on these products. Various methods such as PCR, GC-MS, HPLC, and FTIR have been carried out to distinguish the origin of leather products. The FTIR method is known as an easy and inexpensive method to use. The objective of this study was to evaluate the capability of FTIR spectroscopy and Principle Component Analysis (PCA) for lipid identifcation and initial analysis to distinguish the original materials on leather products. Lipid extracts obtained from the various skin were scanned using an FTIR spectrophotometer at 4000–450 cm-1. It resulted in spectral diﬀerences in several wavenumbers (3000-2800 cm-1 and 1200-1000 cm-1). The same result is also found in lipid spectra from leather product extraction. The FTIR spectroscopy and PCA can diﬀerentiate pigskin and goatskin through specifc peaks in infrared spectra. This can be used as an initial analysis on determining the existence of skin adulteration in leather products. This study is prospective to be continued by chemometrics as quantitative analysis.

Collagen derived from the eggshell membrane, is an increasingly popular functional material. Native chicken is one of the leading local commodities whose industrial waste has the potential to be used as collagen raw material. This study aimed to evaluate the nutrients and morphology of the eggshell membrane of native chicken eggs as raw material for collagen production. The parameters observed were morphology using electron scanning microscopy, mineral composition, and collagen nutrient content (water and protein). SEM observations showed that the eggshell membrane of native chicken eggs was fibrous. The meshed fiber form represents the extracellular matrix present in collagen proteins. The eggshell membrane contains Cl, K, Ca, P, and Mg macrominerals at 1.696%, 1.796%, 14.30%, 0.437%, and 0.146%, respectively. Microminerals I and Mo were also found at 0.00034% and 0.00014%, respectively. The moisture content of the superior native chicken eggshell membrane decreased by 13.05% after the collagen extraction (p<0.05), with a crude protein content of 25.32% after the extraction. It was concluded that the eggshell membrane of native chicken eggs produces fibrous morphological characteristics that are meshed and contain high minerals so that they have the potential to be used as raw materials for collagen production in various applications.

This study aimed to help reduce the lime fleshing solid waste problem by implementing utilization as feed for Black Soldier Fly (BSF) larvae. The BSF larvae were analyzed as a sample to determine whether it is safe to be eaten by other living species, especially catfish. The raw material used is lime fleshing cowhide waste from a leather tannery. The process included fermentation of lime fleshing waste with a formulation of waste: bran: water (8:1:2) for three days, hatching BSF larvae eggs for six days, and feeding fermented waste to BSF larvae (1000:1) for nine days, then baby BSF larvae dried, and BSF larvae were applied to catfish in a ratio (BSF larvae weight = 9: 5) for 12 days. Then, they analyzed the protein, calcium, and sulfur contents on the sample BSF larvae and catfish. We used the fermentation of lime fleshing waste with bran and water variables, which are well water, catfish pond water, and rice washing water, for three days. Then, hatching BSF larvae eggs for six days, BSF larvae cultivation for nine days, and application of the BSF larvae on catfish for 12 days. Data were analyzed by one-way ANOVA, then continued using the Duncan Multiple Range Test (DMRT). The result of fermented lime fleshing waste was used on the BSF larvae, and the cultivation contents were analyzed for protein, calcium, and sulfur. The analysis result of the three variables has an average value of protein at around 6.06%, calcium at 0.041%, and sulfur at around 0.016%. The study concludes that BSF larvae, when combined with commercial feed and suitable formulation, could be an effective and efficient alternative feed for catfish while addressing the lime fleshing waste problem.

The quality of leather is subject to various elements, such as the specific raw material used, and the processing techniques implemented throughout the production process. Goatskin, renowned for its exceptional softness and durability, is frequently employed in the production of gloves owing to its desired attributes, notably its capacity to produce snow-white gloves. Retanning is an essential step in the leather manufacturing process as it significantly improves the characteristics of the leather. Through an investigation into the impacts of distinct retanning agents on goatskin leather gloves, this research endeavor seeks to offer significant knowledge regarding the most effective retanning procedures that can augment the tactile attributes of snow- white leather gloves. In this study, formaldehyde, alum, chromium, and chromium alum were employed as retanning agents. The retanned leathers were assessed by physical parameters, Principal Component Analysis (PCA), and Fourier Transform Infrared spectroscopy (FTIR), then compared to a commercially available snow-white leather glove. The physical characteristics of chrome alum retanned leather showed a high degree of softness (6.60±0.02 mm), good tear strength (1.530±117 N/cm), and tensile strength (1.500±100 N/cm 2 ). The principal component analysis (PCA) also supported that the properties of chrome alum retanned snow-white glove leather closely resemble commercial leather and the result from this study suggested that all factors notably impact the skin's physical quality, except for thickness. Additionally, the FTIR analysis reveals similar functional groups from the different retanned leathers indicated by comparable peaks and stretching patterns. Therefore, chrome-alum could be a well alternative retanning agent for the production of snow-white glove leather.
