Abstract

Polystyrene (PS) microplastics from styrofoam waste are persistent contaminants that are difficult to degrade naturally in aquatic environments and require effective extraction methods for analysis and mitigation. This study aims to determine the optimal conditions of Fe(II) concentration and heating temperature in the Wet Peroxide Oxidation (WPO) method for extracting PS microplastics, as well as to identify their functional groups and elemental composition. The method involved treating polluted water samples using WPO solution consisting of Fe(II) as a catalyst and 30% H₂O₂ as an oxidizing agent, with Fe(II) concentrations of 0.075 M, 0.1 M, and 0.125 M, and heating temperatures of 60°C, 75°C, and 90°C. Microplastic identification was conducted using FTIR and XRF instruments. The results showed that the optimal Fe(II) concentration was 0.125 M, yielding 1.27 grams of microplastics, while the optimal temperature was 60°C, yielding 2.58 grams of microplastics. FTIR characterization confirmed the presence of characteristic PS functional groups, including C-H bending of the benzene ring at 753.22 cm⁻¹ and aliphatic C-H stretching at 2919.27 cm⁻¹, which were also detected in samples from enclosed environments. XRF analysis under optimal conditions indicated that the elemental composition of the extracted microplastics was not entirely pure due to residual contaminants. These findings confirm the effectiveness of the WPO method for extracting PS microplastics under optimized operational conditions.

Abstract

This study is motivated by the limited research on the formulation of organic masks using locally sourced natural ingredients such as coffee grounds, rice flour, and turmeric, which hold potential for producing cosmetic preparations with high bioactive efficacy and safety. The objective of this research is to analyze the effect of turmeric addition on the chemical characteristics of organic facial masks made from coffee grounds and rice flour, with a focus on pH level, moisture content, antioxidant activity, and flavonoid content. A quantitative approach was employed through laboratory experiments involving two formulations (with and without turmeric), each tested in triplicate. pH was measured using a digital pH meter; moisture content was determined by the gravimetric method; antioxidant activity was assessed using the DPPH method with a UV-Vis spectrophotometer; and flavonoid content was evaluated qualitatively. The results show that the formulation containing turmeric had a more neutral pH (7.3), lower moisture content (3.11%), higher antioxidant activity (47.50%), and tested positive for flavonoid content. In contrast, the formulation without turmeric had higher moisture content (3.68%) and did not contain flavonoids. The addition of turmeric also influenced drying time, though it remained within an optimal range. The study concludes that turmeric addition significantly enhances the chemical quality and biofunctional activity of the mask, representing an innovative approach to developing herbal cosmetics based on local ingredients.

Abstract

The rapid development of industry, driven by advances in technology and science, has brought economic benefits but also generated waste with the potential to pollute the environment, particularly aquatic systems. One contaminant of concern is the Pb²⁺ metal ion, known for its toxicity. This study aims to utilize tanah napa from Balai Selasa, Ranah Pesisir, Pesisir Selatan Regency as an adsorbent for Pb²⁺ ions in wastewater. Tanah napa was selected due to its high silica and alumina content, porous structure, and the presence of active groups such as silanol (Si–OH), silica (Si–O), and siloxane (Si–O–Si). Characterization of the material was conducted using Fourier Transform Infrared Spectroscopy (FTIR). Adsorption tests were performed continuously using the column method with variations in concentration and pH. The reduction of Pb²⁺ levels was analyzed using Atomic Absorption Spectrometry (AAS). Results indicated that optimal conditions occurred at a concentration of 250 ppm and pH 4. The adsorption process followed the Langmuir isotherm model with a correlation coefficient of R² = 0.9862 and a maximum adsorption capacity of 3.3467 mg/g. The study concludes that tanah napa has significant potential as a cost-effective and efficient adsorbent for Pb²⁺ ions, offering an alternative solution for industrial wastewater treatment at both laboratory and field application scales.

Abstract

Exposure to chromium(III) ions in liquid waste can have adverse impacts on human health and the environment, thereby necessitating treatment methods that are effective, economical, and environmentally friendly. Various natural materials have been investigated as heavy metal adsorbents; however, studies that specifically evaluate tanah napa from Pesisir Selatan Regency as an adsorbent for Cr³⁺ in a column (continuous) system remain limited. This study aimed to determine the material characteristics and the optimum conditions for Cr³⁺ ion adsorption using activated tanah napa. The research employed an adsorption method in a continuous system, in which the adsorbent with a particle size of 200 mesh (70 µm) was prepared through calcination at 750°C and activation using 1 M KOH. Material characterization was carried out using X-ray Fluorescence (XRF) and Fourier Transform Infrared (FTIR) spectroscopy, while Cr³⁺ ion concentrations were analyzed using an Atomic Absorption Spectrophotometer (AAS). The results showed that the activation process increased the SiO₂ content to 65.781% and enhanced the presence of silanol and siloxane groups that play a role in the adsorption mechanism. The optimum conditions for Cr³⁺ adsorption were achieved at pH 4 with a capacity of 1.0686 mg/g, an initial concentration of 200 mg/L with a capacity of 0.3343 mg/g, and a flow rate of 20 drops/min with a capacity of 1.8464 mg/g. The decrease in adsorption capacity at higher pH values was associated with the formation of chromium hydroxide precipitates, whereas the increase in flow rate reduced the contact time between adsorbate and active sites on the adsorbent. These findings indicate that activated tanah napa has promising potential to be developed as a low-cost alternative adsorbent for heavy metal waste treatment in continuous systems.

Abstract

This study aims to analyze the strategies applied by teachers in shaping students' green behavior in grade IV of SDN Sarakan III, Sepatan District, Tangerang Regency. The approach used is descriptive qualitative. The research subjects include grade IV teachers, students, and the school principal. Data collection was carried out through observation, interviews, and document studies. Data analysis used the Miles and Huberman model, which includes data reduction, data presentation, and drawing conclusions. The research results show that teachers implement five main strategies, namely: (1) designing learning according to the objectives and characteristics of students; (2) encouraging active student participation; (3) presenting material contextually; (4) using Project Based Learning (PjBL) methods and the Contextual Teaching and Learning (CTL) approach; and (5) habituating environmentally caring behavior in everyday school life. The implementation of students' green behavior has been observed in the aspects of knowledge, attitude, and action, although consistency still needs to be improved, especially due to limited school facilities and differences in students' levels of awareness.

Abstract

The quality of coal is significantly influenced by its sulfur content and calorific value, two key parameters in determining energy efficiency and environmental impact. This study aims to analyze the relationship between total sulfur content and gross calorific value (GCV) in coal samples collected from three different locations at PT Bukit Asam Tbk. Sulfur analysis was conducted using a LECO S632 instrument in accordance with the BS ISO 19579:2006 standard, while calorific value was measured using a Parr 6200 bomb calorimeter based on the BS ISO 1928:2020 standard. Analysis of nine samples showed that sulfur content ranged from 0.20% to 0.91%, while final GCV values ranged from 5.790 to 7.772 cal/g. Adjustments for sulfur and acid content resulted in an average decrease in calorific value of 10.3 cal/g. Regression analysis revealed a moderately positive correlation between sulfur content and calorific value, with a coefficient of determination (R²) of 0.4194. Although sulfur in the form of pyrite can contribute energy during combustion, its presence must still be controlled due to the harmful emissions it generates. These findings underscore the importance of sulfur regulation in maintaining energy efficiency and coal quality in line with industry standards.
