This study was conducted to examine the adsorption of Cr (VI) metal using Spirulina sp (inactive) biomass and its application in leather tannery wastewater. The treatment was carried out to determine the influence of independent variables on Cr (VI) adsorption with variations in pH, contact time, and metal solution concentration. The values of the solution pH, adsorption time, and concentration of the best metal solution were used to determine the center points of the optimization variables through Response Surface Methodology (RSM). The results showed that based on the FTIR test, macromolecules present in Spirulina sp biomass included amino, carboxylate, and hydroxy groups. The combination of factor variables that produced the optimum response was at pH 3.165, contact time of 66.58 minutes, and Cr (VI) metal ion solution concentration of 22.9 mg/L, resulting in a Cr (VI) adsorption efficiency of 69.66%. The adsorption pattern was included in the Freundlich adsorption isotherm, and the application of Spirulina sp biomass adsorbent to tannery waste reduced the concentration of Cr (VI) from 3.9 g/L to an undetectable level at <1.4 g/L.

ABSTRACT. Chrome tanning material is still widely used in the tanning process for garment leather production. Its use began to be reduced to overcome its negative environment impact. Vegetable tannin of a mimosa and tara combination was used in this study to substitute chrome tanning material. Garment made from vegetable-tanned leather with a ratio mimosa to tara of 5:13 was compared to garments made from chrome-tanned leather, both the production methods and resulting leather characteristics. To obtain garment leather characteristics, chrome-tanned leather requires auxiliary materials and two fatliquoring steps. Vegetable-tanned leather requires more auxiliary materials and fatliquoring steps (3 steps). Physical test results show that chrome-tanned leather gives better tensile strength, elongation, tear strength, and softness that meet with SNI (Standar Nasional Indonesia or Indonesian National Standard). Meanwhile, garments from vegetable-tanned leather exhibit elongation, tear strength, and softness that meet with SNI. However, adding auxiliary materials and fatliquoring steps in the garment-making process from vegetable-tanned leather is still unable to produce the softness, smoothness, and elasticity of a garment from chrome-tanned leather.

Seiring dengan perkembangan jaman, industri penyamakan kulit dituntut untuk memiliki proses produksi yang lebih bersih namun tetap efektif dan efisien, khususnya pada proses pewarnaan. Proses pewarnaan pada kulit merupakan salah satu tahapan proses penyamakan kulit yang cukup krusial dan menentukan kualitas dari kulit yang akan di hasilkan nantinya. Ultrasonik merupakan teknologi yang memanfaatkan gelombang suara frekuensi tinggi untuk meningkatkan interaksi antara pewarna dan kulit. Teknologi ultrasonik dapat meningkatkan efisiensi pewarnaan dengan mempercepat penetrasi pewarna ke dalam serat kulit. Pada penelitian kali ini dilakukan analisis pada dua metode pewarnaan kulit yaitu metode pewarnaan konvensional dengan menggunakan drum kayu tradisional dan metode pewarnaan kulit dengan menggunakan bantuan mesin ultrasonik. Mesin Mesin ultrasonik yang digunakan yaitu mesin ultrasonik cleaner dengan frekuensi operasi 48 KHz. Selanjutnya dilakukan analisis untuk mengetahui pengaruh penggunaan teknologi ultrasonik dalam proses pewarnaan kulit, dengan fokus analisis pada konsentrasi cairan pewarna selama proses pewarnaan serta warna yang dihasilkan pada kulit. Pada analisis pengaruh waktu terhadap konsentrasi cairan pewarna selama proses pewarnaan, menunjukkan bahwa metode konvensional mengalami penurunan konsentrasi yang cepat pada 15 menit pertama. Sedangkan pada metode pewarnaan ultrasonic, penurunan konsentrasi zat pewarna lebih stabil dan penyerapan warna dapat efisien. Selain itu, pada hasil pewarnaan berdasarkan nilai luminansi menunjukkan bahwa metode ultrasonik menghasilkan warna yang lebih pekat dan mencapai kestabilan warna lebih awal yaitu pada menit ke 30. Sedangkan pada metode konvensional tercapai kestabilan warna pada menit ke 45. Dengan demikian, pewarnaan ultrasonik tidak hanya mempercepat proses tetapi juga meningkatkan kualitas dan kestabilan warna pada produk kulit.

Dead on arrival (DOA) animals, particularly poultry, refer to animals that die during the pre-slaughter phase and are generally considered waste, despite their potential as raw materials for leather production. However, scientific information regarding the quality of leather produced from DOA chicken feet skin remains limited. Therefore, this study aimed to evaluate the feasibility of utilizing DOA chicken feet skin by comparing its physical and chemical properties with those of fresh chicken feet skin after tanning. Chicken feet skin from both sources was processed through beamhouse operations, tanning, post-tanning, and finishing stages before quality evaluation. Physical properties analyzed included thickness, softness, shrinkage temperature, elasticity, tensile strength, tear strength, and seam strength, while chemical properties included pH, moisture content, and oil/fat content. Differences between treatments were analyzed using an independent samples t-test for parameters with sufficient replicates. The results showed that thickness, softness, and shrinkage temperature were not significantly different (P>0.05). Fresh and DOA leather showed comparable seam strength values of 602.52 N/cm and 600.23 N/cm, respectively. Chemical properties were also similar, with pH of 4, moisture contents of 15.16% and 13.82%, and oil/fat contents of 14.94% and 14.05%. Overall, DOA chicken feet skin showed comparable characteristics and potential for leather production.
