Abstract

This research discussed about the application of chitosan from black soldier fly (BSF) pupal exuviae as an adsorbent in the adsorption of napthol dyes in batik wastewater. The adsorption process was carried out in batch process with the aim of analyzing the dye removal efficiency and adsorption capacity as affected by solution pH and adsorbent dosage, as well as determining the appropriate adsorption kinetics model to be applied. Changes in dye concentration were analyzed for absorbance using a spectrophotometer. The results of the adsorption process research showed that the optimal pH and adsorbent dose were at pH 4 and 0.4 g/L with removal efficiency reaching 92%. The removal efficiency decreased with increasing pH. The increasing amount of adsorbent, the removal efficiency decreased. However, after reaching the optimal dose, the addition of chitosan mass no longer gave a significant increase in the removal efficiency, indicating that the saturation point had been reached. The adsorption process tends to follow a pseudo second-order kinetics model with a maximum adsorption capacity of 344.82 mg/g.

Abstract

The adsorption of Methylene Blue (MB) dye from aqueous solutions using natural adsorbents derived from Gamalama volcanic soil was investigated in this study. The adsorbent materials were characterized by FTIR, X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) analyses, confirming the presence of allophane, halloysite, and kaolinite, which exhibit different morphologies and surface properties. Batch adsorption experiments were conducted to evaluate the effects of pH, contact time, and adsorbent mass on the removal efficiency of Methylene Blue. The results demonstrated that Gamalama volcanic soil adsorbents have a high affinity for Methylene Blue, achieving significant removal rates under optimal conditions. The findings suggest that Gamalama volcanic soil is a promising, low-cost, and environmentally friendly adsorbent for treating dye-contaminated wastewater. This study highlights the potential application of natural volcanic soil as an effective adsorbent in environmental remediation. The optimum MB removal was performed by adsorption condition with pH 6, 20 minutes contact time and 30 mg adsorbent.

Abstract

In this research, palm oil mill effluent (POME), was pyrolized using a modified Lampung natural zeolite (LNZ) catalyst. Modification was conducted by reducing the Si/Al molar ratio to 1 by mixing certain mass of food grade aluminum food dissolved in 1.0 M NaOH solution and certain mass of LNZ. The mixture was homogenized using a magnetic stirrer, left at room temperature for 12 hours, and finally subjected to hydrothermal crystallization at 100 ºC for 72 hours. The solid sample produced was dried and calcined at 600 °C for 6 hours then characterized using X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) techniques to evaluate the formation of zeolite-A. The BCO produced from the pyrolysis experiment was analyzed using gas chromatography-mass spectrometry (GC-MS), revealing the presence of hydrocarbon as the main components (70%), suggesting the promising potential of the catalyst for further investigation.

Abstract

This study focuses on the synthesis and characterization of Choline Chloride-based Deep Eutectic Solvents (DES) using Citric Acid (ChCl+CA) and Malic Acid (ChCl+MA) as hydrogen bond donors. The DES were prepared at various molar ratios, and their physicochemical properties, including viscosity, density, pH, water content, and molecular interactions, were comprehensively analyzed. The FTIR spectroscopic analysis revealed key shifts in the functional groups, indicating strong hydrogen bonding between the DES components. While ChCl+CA and ChCl+MA successfully formed stable eutectic solvents at a 1:1 molar ratio, synthesis with higher molar ratios (1:2 and 1:3) and ChCl+Ethylene Glycol (ChCl+EG) were unsuccessful, highlighting the importance of component compatibility and molar ratios. The density and viscosity measurements showed the potential applicability of these DES in extraction processes. This research contributes to the development of DES as green solvents, with future applications in pigment extraction for cosmetic purposes.   Keywords: Deep Eutectic Solvents, Choline Chloride, Citric Acid, Malic Acid, Pigment Extraction, Cosmetic Applications

Abstract

This study investigates the physicochemical properties and molecular insights of Deep Eutectic Solvents (DES) formed with choline chloride as the hydrogen bond acceptor (HBA) and various organic hydrogen bond donors (HBDs), such as citric acid, glycerol, and glycolic acid. DES were assessed for bioactive compound extraction using Fourier Transform Infrared (FTIR) spectroscopy to analyze hydrogen bonding interactions and by measuring viscosity, density, and water content. Results showed viscosity ranging from 100 to 300 mPa-s and density from 1.05 to 1.45 g/cm ³, depending on the specific HBD. DES formed with glycerol and sorbitol exhibited higher viscosity due to stronger hydrogen bonding, while DES with lactic acid and glycolic acid showed lower viscosity, enhancing fluidity. FTIR spectra revealed shifts in the O—H and C=O stretching bands, indicating complex hydrogen bonding networks. These findings highlight the potential of DES to optimize bioactive compound extraction and their application in the cosmetics industry.

Abstract

One variation of functional beverages that is beneficial for the body is powdered goat milk with the addition of kenikir leaf powder (Cosmos caudatus Kunth). Kenikir leaves not only contain bioactive compounds that act as antioxidants, anti-inflammatory agents, and antimicrobials, but they also have high levels of protein, phenolic compounds, carbohydrates, vitamins, and minerals. Therefore, kenikir leaves are utilized as a component to enhance the protein content in functional beverages. The effect of adding kenikir leaf powder to functional beverages on protein content was assessed using the Kjeldahl method, with sample formulations labeled MF(F0), MF(F1), and MF(F2). The results from the Kjeldahl method showed that the highest protein content was found in the MF(F2) sample at 3.58%, while the MF(F1) sample had a protein content of 3.07%, and the MF(F0) sample had 2.49%. This demonstrates that the addition of kenikir leaves increases the protein content in functional beverages. Keywords: kenikir leaves, functional beverages, protein, goat milk.

Abstract

Indonesia, the largest palm oil producer, produces a very large of palm kernel shell waste. This study aims to optimize utilization of this waste by converting it into activated carbon which has high potential adsorbent. Process   making activated carbon involves carbonization and activation of palm kernel shells, followed by surface modification using   magnetic particles and organosilane triethoxyiphenylsilane (TEPS). Addition of Fe3O4 particles can increase adsorption capacity and facilitate the separation of the adsorbent from the solution after adsorption process. Meanwhile, addition of TEPS compounds increases the number of functional groups on the surface of activated carbon so   can interact more strongly with dye molecules. Characterization using various techniques such as UV-Vis, FTIR, XRD, SEM-EDX, and BET was carried out to analyze changes structure and surface properties of activated carbon after modification. The results of the study can contribute to   development of waste processing technology and production of value-added adsorbent materials.

Abstract

The Bengawan Solo River is a primary water resource in Central and East Java. Human activities along the Watershed (DAS) have affected water quality. This study evaluates the water quality of the Bengawan Solo River during the dry and rainy seasons from 2019 to 2023 using the Pollution Index (IP) method, based on secondary data from Perum Jasa Tirta I at four locations: upstream, middle, downstream 1, and downstream 2. The analyzed parameters include physical (temperature, TDS, TSS), chemical (pH, DO, BOD, nitrate), and biological (Total coliform) aspects. The results indicate that pH, TDS, and nitrate remain within quality standards, whereas temperature, BOD, DO, and TSS often exceed the limits, especially during the rainy season. The Pollution Index (Pij) suggests better water quality in the dry season, predominantly classified as "Lightly Polluted." However, in the 2021 rainy season, two locations reached the "Moderately Polluted" category, indicating that rainfall contributes to increased pollution.
