Abstract

Problem-based learning (PBL) has been recognized as an effective method in improving students' critical thinking skills, especially in mathematics learning. This study aims to analyze the implementation of PBL in improving mathematical critical thinking skills of high school students. The research method used was quasi-experiment with post-test only control group design. The research sample consisted of two randomly selected XI classes, with one class as an experimental group that received PBL learning and one class as a control group with conventional learning methods. The results showed that there was a significant difference between the two groups. The average post-test score of the experimental group was higher than that of the control group, with greater improvement in the interpretation and inference indicators. Statistical tests showed that the application of PBL had a significant positive impact on students' mathematical critical thinking skills. The implications of this study indicate that PBL can be used as an alternative learning strategy that is more effective in improving critical thinking skills in mathematics. Therefore, it is expected that teachers can adopt and develop PBL in learning so that students are more active and independent in solving mathematical problems. Further research is recommended to examine other factors that influence the effectiveness of PBL in improving critical thinking skills.

Abstract

Probiotics, which are live microorganisms that benefit the host, have been shown to be effective in preventing and treating antibiotic-associated diarrhea (AAD). However, the specific molecular mechanisms of individual probiotic strains remain poorly understood. This study aims to explore strain-specific approaches for managing gastrointestinal disorders and to provide a scientific overview of the benefits and mechanisms of probiotics in maintaining and improving gut health through complex and interconnected pathways. A systematic literature search was conducted using keywords such as “probiotics,” “gut microbiota,” “strain-specific mechanisms,” “gastrointestinal health,” “host-microbe interaction,” and “synbiotics,” across reputable databases including PubMed, Scopus, ScienceDirect, and Google Scholar. The methodological quality and strength of evidence for each study were assessed using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) framework. Numerous studies have confirmed that probiotics help prevent and treat AAD and may also reduce the risk of irritable bowel syndrome (IBS) and inflammatory bowel diseases. Clinical trials have also shown promising results regarding the ability of various probiotic strains to balance the mucosal immune system and gut microbiota. However, comprehensive research on the synergistic interactions between probiotic and prebiotic strains remains limited. Therefore, future studies should focus on cross-omic approaches, exploration of local strains from traditional diets, and personalized strategies to optimize the efficacy of probiotics in supporting gastrointestinal health.

Abstract

Corrosion is one of the main challenges faced by advanced industries today because it can cause major losses in terms of safety and economy. One of the common protection methods used to reduce the impact of corrosion is polymer-based coating, which can provide hydrophobic properties on the substrate surface. This study aims to examine the effect of variations in the composition of silica-manganese (SiMn) composites reinforced with polydimethylsiloxane (PDMS) on hydrophobic properties, corrosion resistance, and contact angles. The coating method used is spin coating, with the substrate being a mixture of hard and strong silica and manganese which has corrosion-resistant properties. The SiMn compositions varied were 40%:60%, 50%:50%, and 60%:40%. This study is experimental, using tools such as HEM-3D, XRD, SEM, and FTIR. The coating process was carried out by mixing 2.5 grams of PDMS with silica and manganese powders with a total weight of 1 gram, according to the composition variations. The contact angle test was conducted using a DSLR camera, while the corrosion resistance test was conducted using the immersion method in sulfuric acid with the mass loss method. The results showed that variations in composition affected the contact angle and corrosion resistance of the SiMn-PDMS layer. The composition of 0.6 grams of silica and 0.4 grams of manganese produced the highest contact angle of 120.66⁰, indicating higher hydrophobic properties. Conversely, the composition of 0.4 grams of silica and 0.6 grams of manganese showed the lowest corrosion rate, which was 1.57 cm/hour.

Abstract

Effective mathematics learning demands a well-structured approach that encourages students to actively engage in comprehending mathematical concepts. This study explores the effectiveness of the Missouri Mathematics Project (MMP) learning model in improving the mathematics achievement of 11th-grade students at SMAN (X). A quantitative approach was used, employing a quasi-experimental design in the form of a one-group pretest-posttest design. The sample consisted of 30 students randomly selected from the 11th-grade population. Data collection involved two main instruments: an observation sheet to monitor the implementation of the MMP model, and a test of learning outcomes administered before and after the intervention. The results showed a notable improvement in student performance, with the average pretest score being 56.8 and the average posttest score rising to 81.2. Based on N-Gain analysis, a value of 0.65 was obtained, which is categorized as moderate, indicating a meaningful increase in learning outcomes. A paired sample t-test further confirmed this improvement, with a t-count of 8.32 and a significance level of p = 0.000 (p < 0.05). The implementation of the MMP model was rated highly, with an average score of 3.91 out of 4, falling into the excellent category. Moreover, 93.3% of the students achieved scores above the Minimum Completeness Criteria (KKM = 75), demonstrating individual mastery. These findings indicate that the MMP model is effective in enhancing mathematics learning outcomes. The model's structured nature supports active learning and can serve as a promising alternative teaching strategy in high school mathematics education.

Abstract

The increasing scarcity of clean water, exacerbated by population growth and climate change, calls for effective and efficient water management, especially at the household level. This study aims to develop a simple linear mathematical model to estimate daily household water consumption based on commonly observed domestic activities. The total water usage (W) is expressed as a function of key variables such as the number of residents, shower duration, laundry frequency, and dishwashing frequency, each multiplied by an empirical coefficient. These coefficients are drawn from published data to ensure representativeness. A case study conducted on a four-member household in Bandar Lampung, Indonesia, shows an estimated daily water consumption of 631.5 liters, aligning with global benchmarks. The study concludes that this linear model provides a practical and accessible framework for estimating household water use and can serve as a foundational tool for promoting water conservation strategies and informing public policy.

Abstract

This research explores the chemical constituents of bottled drinking water, emphasizing the presence of inorganic and organic pollutants, microplastics, and disinfection byproducts. Samples from five top-selling PET-bottled water brands were analyzed in triplicate under different storage temperatures (room temperature, 4°C, and 40°C). Various analytical techniques were employed: Atomic Absorption Spectroscopy (AAS) to quantify heavy metals (Pb, Cd, Sb), Gas Chromatography–Mass Spectrometry (GC-MS) to detect bisphenol A (BPA) and phthalates, Fourier Transform Infrared Spectroscopy (FTIR) for microplastic identification, and High-Performance Liquid Chromatography (HPLC) to assess trihalomethanes (THMs). Antimony (Sb) was consistently detected, with concentrations increasing markedly at elevated temperatures. BPA appeared in 60% of samples and showed a temperature-dependent increase and inverse correlation with pH. All samples contained microplastics (mean 22 ± 8 particles/L), primarily PET, polypropylene (PP), and polyethylene (PE). Although all contaminant levels were within regulatory thresholds, repeated intake under suboptimal storage conditions may raise cumulative exposure. The results emphasize the need for stricter regulatory measures, enhanced labeling for storage, and standardized guidelines concerning microplastics. This study enhances current understanding by demonstrating how storage conditions influence chemical leaching and potential health risks linked to long-term bottled water consumption.

Abstract

Nanocomposites derived from talc (Mg₃Si₄O₁₀(OH)₂) and montmorillonite (MMT) have gained considerable attention due to their tunable optical, mechanical, and thermal properties. This study systematically compares two synthesis techniques—sol-gel processing and ball milling—for fabricating talc/MMT nanocomposites, with a focus on their optical characteristics. The sol-gel method promoted homogeneous nanoparticle dispersion, while ball milling enhanced exfoliation and reduced particle size. Comprehensive characterization via X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis) spectroscopy, and photoluminescence (PL) spectroscopy revealed that the nanocomposites exhibit strong UV absorption in the 200–400 nm range, a reduced optical bandgap from 4.5 eV to 3.8 eV, and enhanced PL intensity compared to pristine materials. These findings suggest promising applications in UV shielding, optoelectronics, and photocatalytic systems. The study concludes that the choice of synthesis method plays a pivotal role in tailoring the nanocomposites’ structural integrity and optical functionality, with sol-gel favoring intercalation and uniformity, while ball milling enhances exfoliation and defect-mediated performance. This comparative study highlights the critical influence of synthesis method on the structural, morphological, and optical properties of talc/MMT nanocomposites, providing valuable insights for optimizing layered silicate-based materials for advanced functional applications.

Abstract

The rapid growth of industries like petrochemical processing, offshore drilling, transportation, and metallurgy has increased oily wastewater and oil spills, threatening ecosystems and human health. Traditional oil-water separation methods often struggle with low efficiency and poor stability, especially against stable emulsions. This study investigates superhydrophobic materials fabricated via dip-coating on stainless steel mesh, electrospinning of PVDF membranes, and chemical etching of aluminum surfaces. All materials showed excellent water repellency with contact angles over 150°, achieving oil-water separation efficiencies above 97% for various oils. The dip-coated mesh achieved the highest flux and separation efficiency, while the electrospun membrane offered enhanced chemical resistance and durability. Despite promising results, challenges remain including mechanical abrasion resistance, environmental concerns over hydrophobic coatings, and scalability for industrial use. Future research should focus on eco-friendly, self-healing, and stimulus-responsive coatings to improve durability and environmental safety, advancing the practical application of superhydrophobic materials in wastewater treatment and oil spill remediation.

Abstract

Hospitals are significant sources of wastewater containing pathogenic microorganisms, particularly enteropathogenic and toxigenic Escherichia coli (E. coli), which pose serious health and environmental risks if left untreated. This study evaluated the effectiveness of nanofiltration (NF) membranes in reducing E. coli concentrations in hospital wastewater using the Most Probable Number (MPN) method. Samples were collected from a type B hospital in Palembang, Indonesia, and treated with NF membranes operated at 60 psi and contact times between 10 and 60 seconds.The NF membrane achieved high removal efficiencies ranging from 99.75% to 100%, with complete elimination of E. coli at retention times of 30 seconds or more. This confirms nanofiltration as an effective tertiary treatment method for improving the microbiological quality of hospital effluent and ensuring compliance with discharge standards. The membrane's performance is attributed to its fine pore size and electrostatic repulsion of bacterial cells.To enhance practical application, future studies should focus on scaling up to full or industrial levels, evaluating long-term performance, fouling behavior, maintenance needs, and economic feasibility. Such efforts are vital to integrating nanofiltration into sustainable hospital wastewater management systems that protect public and environmental health.
