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

Phyllanthus niruri L., a medicinal plant from the Phyllanthaceae family, is widely recognized in traditional medicine for its flavonoid content in the leaves, which functions as a natural antioxidant protecting cells from damage caused by free radicals. This study aims to investigate the effect of the Maceration Vortex Technique (MVT) on the total flavonoid content of Phyllanthus niruri leaves. The method involved a 2-hour maceration process followed by 5 minutes of vortexing using 70% ethanol as the solvent. Total flavonoid content was analyzed using UV-Vis spectrophotometry at a maximum wavelength of 431 nm. The results demonstrated that the MVT method yielded a high flavonoid content, indicating the technique's effectiveness in extracting flavonoid compounds from Phyllanthus niruri leaves. The study concludes that MVT is a promising alternative extraction method that is efficient, simple, and applicable for obtaining bioactive compounds from natural sources. These findings have positive implications for the development of antioxidant-rich herbal products derived from natural ingredients.

Abstract

Household waste largely consists of organic materials such as vegetable scraps, fruit peels, and leaves, which have the potential to be transformed into eco-friendly products like eco enzyme. Eco enzyme is a fermentation product of organic waste combined with palm sugar and water, which can be used as a cleaning solution, fertilizer, natural pesticide, and water quality enhancer. This study aims to examine the characteristics of eco enzyme made from pineapple, orange, and cucumber peels in both fresh and dried forms, using a mixing ratio of 3:1:10 for organic waste, palm sugar, and water, respectively. The parameters analyzed included pH, total dissolved solids (TDS), fermentation yield volume, and tannin content as a phytochemical compound. The results showed that eco enzyme from fresh waste had a pH of 3.65, TDS of 127 ppm, and a volume of 2200 ml, whereas the product from dried waste had a pH of 3.53, TDS of 235 ppm, and a volume of 1000 ml. Tannin testing using FeCl₃ reagent indicated that neither sample contained tannins. Based on these findings, it can be concluded that eco enzyme produced from both fresh and dried organic waste exhibits favorable chemical properties and is suitable for use as an environmentally friendly household cleaning solution.

Abstract

Cd(II) and Zn(II) metal ions are toxic environmental contaminants that pose potential risks to human health, necessitating accurate and efficient detection methods. This study aims to optimize the supporting electrolyte conditions for the simultaneous electrochemical detection of Cd(II) and Zn(II) ions using a Pencil Lead Electrode (PLE) modified with a thin silver layer (Ag/PLE). Cyclic voltammetry was employed to evaluate the effectiveness of electrode modification and the influence of electrolyte variation on the detection sensitivity of both metal ions. Experimental results indicate that 0.1 M acetate buffer is the optimal supporting electrolyte, yielding an anodic potential (Epa) of –0.37 V and a peak current of 1.48 mA, as well as a cathodic potential (Epc) of –0.9140 V for Cd(II). For Zn(II), the Epa was observed at –0.79 V with a current of 0.54 mA and Epc at –0.6790 V. The difference in detection sensitivity between the two metal ions is attributed to variations in analyte diffusion rates at the electrode surface. These findings demonstrate that the Ag/PLE-based electrochemical approach offers a simple, sensitive, and cost-effective method for the simultaneous detection of heavy metal ions, contributing significantly to rapid and practical environmental monitoring systems.

Abstract

This study is motivated by the limited research on the use of modified pencil lead electrodes in electrochemical detection, despite their advantages as simple, low-cost, environmentally friendly, and highly sensitive heavy metal sensors. Copper ions (Cu²⁺) are essential elements for biological functions, but in excessive amounts, they become toxic and can damage vital organs such as the liver and kidneys. The aim of this research is to develop an effective electrochemical sensor for detecting Cu²⁺ ions by optimizing the type and modification of pencil lead electrodes. Electrode modification was performed using the drop-casting method with manganese dioxide (MnO₂) on three pencil hardness grades (2B, B, and HB), with voltammogram analysis based on the resulting current and redox potential. The results indicate that the MnO₂/PLE (2B) electrode demonstrated the most optimal performance compared to the other variations. This advantage is attributed to the electrocatalytic properties of MnO₂ and the higher graphite content in 2B pencils, which enhance the electrode’s conductivity and electrochemical response. These findings confirm that MnO₂/PLE (2B) is effective for Cu²⁺ ion detection and holds potential for development as an efficient electrochemical sensor for heavy metal analysis.

Abstract

Industrial waste containing heavy metal ions such as Cu(II) is a major cause of environmental pollution, posing serious risks to human health and ecosystem sustainability. Cu(II) ions are toxic and can lead to neurological disorders, anemia, liver and kidney damage, and even death upon excessive exposure. To address this issue, an efficient, economical, and environmentally friendly method is needed. This study aims to evaluate the ability of matoa peel as a biosorbent for Cu(II) ion removal and to analyze the effect of surface modification using the cationic surfactant Cetyltrimethylammonium Bromide (CTAB). Matoa peel was selected due to its status as agricultural waste rich in active compounds such as flavonoids, tannins, lignin, and cellulose, which contain functional groups effective in binding metal ions. CTAB modification was applied to enhance the number and strength of active adsorption sites. Characterization was conducted using Fourier Transform Infrared Spectroscopy (FTIR) to identify changes in functional groups, while adsorption tests were performed using Atomic Absorption Spectroscopy (AAS) with variations in contact time and stirring speed. The results indicated optimal conditions at 60 minutes of contact time and a stirring speed of 150 rpm, achieving a maximum adsorption capacity of 15.01 mg/g—significantly higher than that of the unmodified biosorbent. In conclusion, CTAB-modified matoa peel significantly enhances the biosorption effectiveness for Cu(II) ions. These findings support the potential use of agricultural waste as a sustainable, cost-effective biosorbent for environmentally friendly industrial wastewater treatment.

Abstract

This study is motivated by the limited research on phytochemical screening of combined medicinal plant extracts, despite the significant potential of this approach in developing more effective and efficient herbal medicines. The objective of this research is to explore the presence of secondary metabolites in a combination extract of kecibeling leaves (Strobilanthes crispa (L.) Blume) and papaya leaves (Carica papaya L.). A qualitative method was employed, with leaf samples purposively collected from the Lima Puluh Kota Regency, West Sumatra. Data were obtained through phytochemical screening tests using specific reagents to detect alkaloids, saponins, flavonoids, tannins, phenolics, triterpenoids, and steroids, and were analyzed descriptively. The results revealed that the combined extract contained saponins, flavonoids, tannins, phenolics, and triterpenoids, while alkaloids and steroids were not detected. These findings support the theory of possible synergistic effects among secondary metabolites in combined extracts, particularly in enhancing the presence of compounds such as tannins that were not identified in single extracts. The study concludes that combining plant extracts can enrich the phytochemical profile. Its implications include contributing to the scientific literature on the potential of local plants and offering practical recommendations for researchers and the herbal industry to consider combination formulations in the development of natural medicinal products. Furthermore, this research opens opportunities for follow-up studies on the pharmacological activity and toxicity of the combined extracts.

Abstract

Polyethylene Terephthalate (PET) microplastics are among the primary contaminants in aquatic environments and pose potential risks to human health. Coagulation is an effective method for reducing microplastics; however, conventional coagulants such as alum may leave harmful residues. This study aims to evaluate the effectiveness of chitosan synthesized from crab shell waste (Scylla serrata) as an eco-friendly biocoagulant in the coagulation of PET microplastics. Chitosan synthesis was carried out through three stages: demineralization, deproteinization, and deacetylation. The coagulation process was conducted under varying pH conditions (3, 5, 7, 9, and 11), with a chitosan dosage of 500 mg/L and a sedimentation time of 45 minutes. The results show that optimal conditions were achieved at pH 7, with microplastic removal efficiency reaching 98.4%. Characterization using Fourier Transform Infrared Spectroscopy (FTIR), Particle Size Analyzer (PSA), and stereo microscopy confirmed successful floc formation and active interaction between chitosan and microplastics. The study concludes that chitosan derived from crab shell waste has strong potential as an effective and environmentally friendly alternative coagulant for treating water contaminated with microplastics.

Abstract

This study aims to evaluate the effect of Diethanolamine (DEA) addition on the band gap energy and crystal structure of TiO₂ semiconductors doped with ZnO using the sol-gel method. DEA functions as a stabilizing agent and particle growth controller to achieve more uniform particle size and distribution. DEA concentrations of 1%, 2%, 3%, 4%, and 5% were applied. The synthesis process involved mixing TiO₂ and ZnO in ethanol, adding DEA, sonication, drying, and calcination. Characterization was conducted using UV-Vis Diffuse Reflectance Spectroscopy (UV-DRS), employing the Kubelka-Munk approach to determine the band gap values. The results indicate that DEA addition significantly reduced the band gap energy to 3.05 eV at the optimal concentration of 4%, attributed to the formation of structural defects and reduced particle size, which expanded the active surface area and shortened the electron excitation distance. However, at 5% DEA concentration, the band gap increased to 3.14 eV due to particle agglomeration. These findings confirm the crucial role of DEA in controlling the optical properties of TiO₂-ZnO, with a 4% concentration offering optimal performance for photocatalytic and solar cell applications. This study demonstrates that chemical additive manipulation during synthesis is an effective strategy for engineering the electronic properties of semiconductors.
