Abstract

The dual challenge of environmental degradation and the global demand for halal-certified products highlights the urgent need for sustainable and Sharia-compliant innovations in household cleaning agents. This study addresses the specific problem of formulating a detergent that is both environmentally friendly and halal by utilizing fermented orange peel waste (Citrus sinensis (L.)) and Citrus limon(L.) Burm. f to produce eco enzymes. Employing an experimental quantitative approach, the research investigates the production, formulation, and performance evaluation of eco enzyme-based detergents. Key tests included fermentation kinetics, pH analysis, organoleptic properties, and compliance with the Indonesian National Standard (SNI) for detergent quality specifically assessing cleaning efficacy, pH balance, foam stability, and user acceptability. The resulting eco enzyme exhibited a pH of 3 and a characteristic citrus aroma, while the formulated detergent demonstrated effective cleaning power and met all SNI criteria. This research not only offers a practical solution for reducing reliance on synthetic surfactants but also contributes to the growing body of halal green chemistry.

Abstract

Indonesia is one of the countries with a growing number of diabetes mellitus cases each year. This disease can cause damage to vital organs such as the liver, pancreas, kidneys, and heart. Type 1 diabetes is generally treated with insulin, while type 2 diabetes is commonly managed with oral medications. Recently, metal complexes have emerged as promising alternatives for antidiabetic therapy. Among these, iron(III) complexes are of interest, although research on Fe(III) complexes remains limited. This study aims to synthesize and evaluate the in vivo antidiabetic activity of an iron(III)-glycine complex. The synthesized complex appeared as an orange-brown solid with a yield of 95.02% and a sample mass of 0.267 g. UV-Vis spectrophotometric analysis showed absorption peaks at 210, 224, and 305 nm, indicating the presence of the Fe(III)-glycine complex. FTIR analysis revealed characteristic absorption bands corresponding to Fe–O at 523 cm⁻¹ and Fe–N at 823 cm⁻¹. In vivo tests were conducted on mice induced with alloxan. Body weight of the mice decreased after induction but stabilized after treatment during the third and fourth weeks. The highest reduction in blood glucose levels was observed at a dose of 200 μg/kg body weight, with a 68% decrease. These results suggest that the Fe(III)-glycine complex exhibits potential as an antidiabetic agent.

Abstract

Various human activities that are increasing will have an impact on the decline in the quality of raw water, a key source of clean water production. To achieve optimal results in the clean water treatment process, a suitable formulation is required for the addition of liquid PAC, which acts as a coagulant to reduce the turbidity level of raw water. Currently, the formulation of liquid PAC dosage in raw water treatment has an accuracy level of less than 70%. Therefore, a method is needed to improve the accuracy level of PAC dosage. Box-Behnken Design (BBD) is one of the RSM design methods, which can analyze problems whose responses are influenced by several variables, where the interaction can be used to predict the optimal formula. This study aims to determine the optimal dosage of liquid PAC required for clean water treatment using the Box-Behnken Design. Before the optimization process is carried out, it is necessary to select parameters that have a significant effect. The methodology in this study is divided into two main stages. The first stage involves parameter selection using Design-Expert Two-Level Factorial, with five parameters tested: liquid PAC dosage, turbidity, pH, stirring speed, and stirring time. The second stage involves optimizing parameters that have a significant effect using Design-Expert Box-Behnken. The results obtained from the parameter selection process indicate that turbidity and liquid PAC dosage have a significant effect. Optimization is carried out by entering the turbidity parameters and liquid PAC dosage as independent variables, with the response being the final turbidity. The results show that in water with turbidities of 20 NTU, 60 NTU, and 100 NTU, the optimum liquid PAC concentration is 50 ppm, with percentage reductions in turbidity of 95.72%, 97.13%, and 97.37%, respectively. BBD shows that there is a significant parameter interaction between the turbidity parameter and the liquid PAC dosage, while there is no significant interaction between the turbidity parameter and pH, and the pH parameter and the liquid PAC dosage.

Abstract

Fossil fuels, such as petroleum, are non-renewable and have been exploited for decades, necessitating alternative energy solutions. Biodiesel reduces reliance on fossil fuels and mitigates their environmental impact. This research converts used cooking oil into biodiesel through chemical reactions—esterification and transesterification—that transform oils into biodiesel. Microwave heating accelerates reaction rates and reduces process times compared to conventional heating. A CaO catalyst derived from eggshells, impregnated with ZnO and supported by activated carbon, was chosen for its sustainability and enhanced catalytic activity. The study aims at determining the optimal conversion time for transforming used cooking oil into biodiesel according to SNI 7182-2015, using FT-IR and GC-MS analyses to assess chemical composition and purity. XRD and SAA confirmed the formation of CaO and a surface area of 3.822 m²/g. Microwave heating times of 4-8 minutes at 600 watts were tested, with the highest yield (89.62%) achieved in 5 minutes. This meets SNI 7182-2015 standards for density, kinematic viscosity, acid number, and saponification number. GC-MS identified cis-13-octadecenoic acid methyl ester (52.69%), pentadecanoic acid 14-methyl methyl ester (31.89%), and methyl stearate (6.14%) as the main components. These results demonstrate sustainable biodiesel production from waste cooking oil using environmentally friendly catalysts, reducing reliance on fossil fuels.

Abstract

This study determined fluoride levels in bottled drinking water and toothpaste using a fluoride ion-selective electrode (F-ISE) and verified the results using a colorimetric method based on alizarin complexone with UV–Vis spectrophotometry. F-ISE calibration with NaF standards (0.01–1.0 mg/L) in TISAB (1:1) showed excellent linearity (R² = 0.9996) and near-Nernstian response, with an average recovery of 88.2%. Most bottled water samples contained fluoride below the safety limit, except one brand (IND) with 2.289 mg/L, exceeding the WHO guideline (1.5 mg/L). Among toothpaste samples, one adult formulation (PEP) met BPOM standards, two children’s products (KOD and ENZ) were within safe ranges, while another adult product (CAL) exceeded the recommended fluoride level. Cross-validation on four representative samples showed good linearity for the colorimetric method (R² = 0.998) and inter-method deviations below 4%, indicating strong agreement between the two analytical approaches. The effect of Al³⁺ and Fe³⁺ interference on F-ISE measurements was also assessed. Without TISAB, fluoride readings decreased by 18–28% due to complex formation, whereas TISAB addition effectively minimized interference, leaving a residual bias of 1.7–4.4%.

Abstract

Antioxidants are compounds that can overcome the effects of free radicals. One of the plants that has antioxidant activity is the Porang plant (Amorphophallus muelleri). This study aims to determine the antioxidant activity of the Porang leaves’ ethanol extract and fraction using the DPPH method. Porang leaves were extracted using maceration with 96% ethanol and separated by fractionation using n-hexane and ethyl acetate. The ethanol extract and the three fractions were tested for their activity as antioxidants using the DPPH method with ascorbic acid as positive control. Phytochemical screening and Total Flavonoid Content (TFC) assay were also conducted. Phytochemical screening showed the presence of flavonoids, tannins/polyphenols, and terpenoids. Quantitative test for Total Flavonoid Content (TFC) showed that the greatest flavonoid content was found in the ethyl acetate fraction, which was 101.93 ± 2.75 mgQE/g. The results showed that the strongest antioxidant activity was possessed by ethanol extract (IC50 66.39 ± 0.44 µg/mL), followed by the ethyl acetate fraction (IC50 72.19 ± 4.37 µg/mL), ethyl acetate insoluble fraction (IC50 135.48 ± 2.54 µg/mL), and the weakest was n-hexane fraction (IC50 198.31 ± 16.75 µg/mL). Hence, cream was prepared using ethanol extract which possesses the strongest antioxidant activity. Formula 4 (7.5% extract) showed the strongest antioxidant activity (IC50 1,637.12 µg/mL), followed by formula 3 (5% extract) with IC50 of 2590.377 µg/mL, formula 2 (2.5% extract) with IC50 of 3,898.694 µg/mL, and formula 1 (cream base) with IC50 of 110,727.4 µg/mL. All cream formulations which contained porang leaves extract (F2 – F4) had higher antioxidant activity than formula 1 (base), although their antioxidant activity was classified as very weak.

Abstract

Golden snails are widely recognized as significant pests in Indonesian rice fields because they damage young rice plants by attacking their stems and leaves. Despite their harmful agricultural impact, golden snail shells contain a high calcium carbonate (CaCO₃) content of approximately 60.56%, making them a valuable raw material for calcium oxide (CaO) production through calcination. In this study, golden snail shells were calcined at 700, 800, and 900°C for 5 hours. The resulting CaO materials were characterized using Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), and Brunauer Emmett Teller (BET) surface area analysis. The findings demonstrate that calcination temperature significantly influences the physicochemical properties of the produced CaO, particularly its surface area. Among the tested conditions, the sample calcined at 900°C exhibited the highest specific surface area of 244.5211 m²/g, indicating enhanced porosity and a greater number of potential active sites at elevated calcination temperatures.
