Abstract

This study utilizes the adsorption process to reduce the concentration of lead ions in battery industry wastewater by using adsorbents from water hyacinth (Eichhornia crassipes). This research aims to determine the ability of a bioadsorbent activated by a 0.1 M HCl solution to adsorb Pb2+ through FTIR and AAS characterization. The bioadsorbent was contacted into a standardized solution of Pb2+ with varying contact times (viz., 20, 30, 40, 50, 60, 70, 140, 210, and 280 to determine the maximum adsorption). The highest absorption of the Pb2+ in battery industry wastewater took place for 210 minutes. The absorption ability was 94.45%, with 8.1488 ppm as the initial concentration. Then, this study shows that this characterization before the activation of 0.1 M HCl has O-H, C-H, C=O, and C-O ether functional groups. All three identified the presence of cellulose. Post-activation, lignin, and hemicellulose disappeared due to the vibration of the C=O group. However, an increase in the intensity of the vibrational peak at the C-O group indicates the presence of carbon chain linking in cellulose. Finally, after contact with battery industry effluent, bending vibrations were lost because the H atoms in the functional groups had been substituted with Pb2+.

Abstract

Limbah yang dihasilkan perusahaan JKLMN berupa limbah padat dan cair. Penanganan limbah cair diserahkan kepada Unit Pengolahan Limbah Air dan pihak ketiga membantu pemrosesan limbah padat. Fokus penelitian ini adalah pengolahan limbah secara anaerobik dengan menggunakan 3 (tiga) uji berupa BOD5, COD, dan TDS. Penerapan metode tersebut ditujukan untuk mengetahui potensi teknologi terhadap limbah cair yang dihasilkan perusahaan. Data pengamatan menunjukkan bahwa nilai parameter TDS mendekati nilai standar baku mutu pada hasil ulangan ketiga selama 6 (enam) hari. Peningkatan waktu tinggal limbah bukan merupakan solusi. Beban proses disebabkan limbah cair (segi jenis dan jumlah) yang menghasilkan ketidakseragaman produk dalam setiap waktu proses.

Abstract

Ginger is one of Indonesia's most abundant and widespread cultivated plants and is widely used in people's daily lives as a raw material and additive in the manufacture of food and beverages. One type of ginger that is in great demand in the herbal beverage industry is red ginger. The bioactive compounds found in ginger include 6-gingerol, 6-paradol, 6-methylshogaol, 8-methylshogaol, 8-gingerol, 10-gingerol and 6-shogaol. Red ginger contains various bioactive compounds with pharmacological effects such as analgesic, anti-inflammatory, anti-cancer, antioxidant and cardiotonic effects. Scanning Electron Microscopy (SEM) is a microscopy technique used to produce high-resolution images of the surface of an electron sample. This study aimed to analyze the porosity of red ginger powder against variations in temperature and sugar content. The temperatures were 80 and 90°C with a sugar content of 60 and 100%. The results showed that the increase and decrease in the percentage of porosity values were caused by differences in temperature variations applied to the crystallization process. The rate of red ginger powder's porosity that approaches the fresh red ginger rate is red ginger powder at 80°C and 60% crystallization agent. The research results contributed to the characteristics of the materials used and the development of red ginger drink powder products.

Abstract

Red ginger (Zingiber officinale) is recognized as a medicinal plant with multiple benefits. The medicinal benefits of red ginger necessitate cautious handling and treatment to avoid damaging the compounds present in ginger. Producing red ginger powder to make an instant red ginger drink is one of the most frequent methods of ginger processing. The aim of this study is to investigate the impact of raising the temperature during the evaporation-crystallization process (at 80 and 90 oC). Then, the proportion of crystallization agent is rock sugar (at 60 and 100%), which alters the color of red ginger extract, both in terms of research outcomes and commercial products. Each specimen is provided in the form of a solid stage (red ginger powder) and a liquid phase, whereby the red ginger powder is dissolved in hot water (approximately 50 oC). The color of both products was analyzed using a chromameter. The results indicate that the product samples' color changed with the color components L (dark-light), a (red-green), and b (yellow-blue). These changes were caused by an increase or decrease in the amount of dye in the red ginger extract. This caused carotenoids (red) and oleoresin (yellow). Additionally, they indicated a Maillard reaction due to the increase in temperature during the evaporation-crystallization process. The optimum outcomes of this research were observed when fresh raw materials were exposed to 90 °C and 100% cube sugar content. Notably, the color values exhibited no significant discrepancies from those of commercially available red ginger products.

Abstract

Lead, which is one of the most important heavy metals, is a worldwide toxic pollutant. Adsorption is one of the methods used to study the removal of heavy metal ions from solutions, which encourages us to study the reduction of Pb2+ concentrations in wastewater from the battery factory in this study. The best conditions for adsorption were found using a bioadsorbent called 0.5 M NaOH-activated water hyacinth. This was studied using FTIR to identify the plant. This research conducted adsorption tests on a 20 ppm Pb2+ standard solution, varying the contact times to 20, 30, 40, 50, 60, 70, 140, 210, and 280 minutes. At the contact time of 140 minutes, the Pb2+ concentration reduced to 0.1558 ppm with a 98.0881% adsorption efficiency. Before the bioadsorbent treatment, the FTIR analysis of O-H, C-H, C=C, and C-O functional groups showed that cellulose was present. Activation eliminates the C=C peak and reduces the intensity of the O-H peak. This shows that the lignin and hemicellulose chains are breaking down. When the bioadsorbent binds to Pb2+, the vibrational frequencies of the C-H and C-O groups change, which shows that it works. The results show that the water hyacinth bioadsorbent activated by NaOH is a good alternative material for dealing with Pb2+ waste, which lowers the amount of lead in industrial waste water by a large amount.

Abstract

Elemental lead is one of the pollutants generated from batteries. To overcome this problem, technologies such as the use of bioadsorbents have been developed to reduce heavy metal content in wastewater. This study aims to determine the adsorption of lead metal ions (Pb2+) through the use of a water hyacinth (Eichhornia crassipe) bioadsorbent activated with nitric acid (HNO3). Another objective is to obtain the optimum adsorption time on battery industry waste discharges. Post-treatment characterization using FT-IR. Contact time variations (20, 30, 40, 50, 60, 70, 140, 210, and 280 minutes) were used to carry out the lead metal adsorption process on a standard solution of metal ions (Pb2+), 20 ppm. The results showed that the optimum contact time was 210 minutes. This achievement was used as the contact time for reducing the levels of Pb2+ metal ions. The quantity of the remaining Pb2+ metal ion content was 0.4184 ppm. Indirectly, the bioadsorbent performance was 94.8655%. Characterization through FT-IR equipment before activation of water hyacinth bioadsorbent gave results of O-H, C-H, C=O, and C-HO functional groups. These findings indicated the presence of lignin, hemicellulose, and cellulose compounds in the sample before activation. Then, the involvement of 1 N HNO3 solution (as an activator) resulted in a decrease in the quantity of C=O and C-OH functional groups. The process of applying the solution was able to break a number of chains between lignin and hemicellulose. After the adsorption process was given, the waste left the vibrations of O-H, C-H, and ≡C-H groups at wave numbers shifted in a smaller direction. This can occur due to changes in functional groups that have bound metal ions first.
