Abstract

The increased use of synthetic gloves made from plastics such as nitrile and vinyl resulted in serious environmental problems due to plastic waste that was difficult to decompose. This study aimed to utilize banana peel waste for producing antibacterial organic gloves with the addition of latex. The manufacturing method involved mixing latex with ionol as an antioxidant, sulfur for vulcanization, and banana peel powder to add antibacterial properties. Tensile strength testing was conducted by varying the proportion of banana peel and chemical treatment using NaOH and NH4OH solutions. The results showed that increasing the proportion of banana peel led to a decrease in tensile strength and elongation of the material, from 22.5 MPa and 550% at a 10% banana peel ratio to 16.0 MPa and 480% at a 40% ratio. Treatment with NaOH resulted in a greater reduction than NH4OH. This study demonstrated that banana peels had potential as an environmentally friendly additive for the manufacture of antibacterial organic gloves. To improve its effectiveness, it was recommended that future research focus on optimizing the proportion of ingredients, developing the production process, and evaluating costs to achieve an optimal balance between quality, durability, and production efficiency

Abstract

This study was aimed at assessing the effectiveness of Project-Based Learning (PjBL)-based analytical chemistry flipbooks in improving students’ critical thinking skills and scientific literacy, and linking the results to the achievement of Sustainable Development Goals (SDG-4), namely quality education. This study used a quantitative approach with a quasi-experimental design, involving two groups: an experimental group (n = 250) using PjBL-based flipbooks, and a control group (n = 250) using conventional textbooks. The projects in PjBL were designed to challenge students to apply critical thinking skills in solving real problems in analytical chemistry. Scientific literacy was measured based on students’ ability to understand, evaluate, and apply chemical concepts in the context of the project. Critical thinking skills and scientific literacy tests were used to measure learning outcomes before and after the intervention. The instrument in this study was a test of critical thinking skills and scientific literacy. Statistical tests showed that the data were normally distributed (significance value 0.216), homogeneous variance (0.074), and significant differences between the experimental and control groups (t = 0.038, p < 0.05). The increase in n-gain in the experimental group reached 0.9 (high category), compared to 0.63 (moderate category) in the control group. This study concluded that Project-Based Learning-based flipbooks were significantly more effective than conventional textbooks in improving students’ critical thinking skills and scientific literacy. The results of this study confirmed the superiority of PjBL-based flipbooks in significantly improving students’ critical thinking skills and scientific literacy compared to conventional textbooks. Statistical data support (normal distribution, homogeneous variance, significant differences between groups, and high n-gain in the experimental group) encourages the adoption of PjBL-based flipbooks as an effective learning strategy to achieve quality education according to SDG-4.

Abstract

Access to quality education remains a challenge in developing nations, including Indonesia. Augmented reality (AR) has emerged as a promising tool to address this gap. This review aimed to examine AR applications in education from 2001 to 2024, focusing on their impact on learning outcomes and accessibility. The study analyzed 171 articles selected through a systematic search in databases like scopus and IEEE explore. Key aspects reviewed include AR tools, applications, evaluation methods, and target demographics. Findings highlight ARs effectiveness in STEM education, vocational training, and cultural learning through features like 3D visualizations, interactive simulations, and animations, enhancing engagement and skill acquisition. AR aligns with sustainable development goals 4 (quality education), 9 (industry, innovation, and infrastructure), and 10 (reduced inequality) by improving access to education and reducing inequalities. However, challenges such as inadequate teacher training, limited infrastructure, and the need for localized content hinder broader implementation. The review concludes that AR tools should address pedagogical and contextual needs for optimal impact. Recommendations include expanding teacher training, improving access to technology, and developing culturally relevant content. Future research should explore scalable, long-term AR solutions to enhance global education

Abstract

This study discussed the use of iron (Fe) complex compounds in the form of chelates such as EDTA, DTPA, EDDHA, and amino chelates to overcome Fe deficiency in plants. Fe deficiency often occurs in soils with high pH or calcareous soils, which can be seen from chlorosis in leaves and decreased productivity. This study was aimed to review the synthesis, stability, agronomic effectiveness, and environmental impact of various types of Fe chelates. The methods used in this study were literature studies, with data sources covering articles from 2016 to 2025, with a particular focus on articles discussing the use of Fe chelates in plants. The findings of this study indicated that Fe-EDTA works well at low to moderate pH levels but is less stable in alkaline soils. Fe-DTPA showed moderate stability up to pH 7, while Fe-EDDHA had high stability even at pH 9, making it more suitable for calcareous soils. More environmentally friendly alternatives such as Fe-amino chelates have been proven to be more easily absorbed, have a positive impact on the environment, and also function as biostimulants. Therefore, further research is recommended to explore the development of environmentally friendly and effective Fe-chelates in alkaline soils to reduce residues from synthetic materials.
