Abstract

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

This study aims to analyze the effect of phytoremediation on the bioremoval of COD, ammonia, and Cr (VI) from tannery wastewater and examine its effect on the growth of Chlorella populations. The research method consisted of two stages: first, preparation of liquid waste media. The second is culturing pure cultures followed by microalgae cultivation using leather tanning liquid waste media with a concentration variation of 0%, 10%, 20%, and 30% v/v. Filtrate samples after harvest were analyzed for COD, ammonia, and Cr (VI). The results obtained in this study show that Chlorella can grow in tanning waste media. The highest exponential phase occurs at a concentration of 20% with a growth rate of 0.557. Tannery liquid waste contains inorganic minerals utilized by Chlorella pyrenoidosa cells for growth. Cultivation of Chlorella pyrenoidosa can reduce leather tanning liquid waste parameters, namely COD, ammonia, and Cr (VI).

Abstract

Proses penyamakan kulit merupakan suatu proses konversi bahan organik yang mudah membusuk menjadi bahan stabil yang mampu menahan serangan biokimia Salah satu parameter penting dalam proses penyamakan kulit adalah  suhu pengkerutan kulit. Suhu pengkerutan kulit adalah suhu yang dicapai pada saat kulit mengkerut maksimum 0,3% dari panjang awal, jika kulit dipanaskan secara perlahan-lahan dalam media pemanas. Saat ini masih banyak pelaku industri di dalam negeri yang melakukan uji suhu pengerutan kulit penyamakan dengan menggunakan metode manual namun metode tersebut sangat tidak akurat karena tergantung kejelian operator dalam melihat kulit. Selain itu untuk mengetahui kemasakan kulit juga dapat dilakukan dengan menggunakan alat Leather Shrinkage yang diperjual belikan salah satunya alat Leather Shrinkage merk Gester seri GT-KC23. Namun harga alat tersebut cukup mahal sehingga kurang aplikatif pada industri pengolahan kulit yang berskala kecil dan menengah. Pada penelitian ini akan dilakukan rancang bangun alat pengukuran suhu kerut kulit tersamak yang lebih praktis dan mudah dalam penggunaannya, serta metode pengujiannya sudah baku sesuai dengan Standar Nasional Indonesia (SNI) 06-7127-2005. Alat pengukuran suhu kerut menggunakan sensor suhu air PT-100, pemanas, dan rangkaian indikator pergerakan manual. Data dari sensor suhu akan diproses oleh mikrokontroler Arduino uno.  Pada rancangan alat uji ini dilakukan uji coba pada 4 macam kulit yaitu, kulit nabati, kulit pickle, kulit chamois dan kulit aldehyde. Berdasarkan hasil pengujian alat pada kulit pickle, kulit chamois dan kulit aldehyde juka dibandingkan dengan hasil pengujian dengan alat Leather Shrinkage merk Gester seri GT-KC23 dianggap sudah cukup representatif.

Abstract

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.
