Abstract

The challenge of developing environmentally friendly synthesis methods for biologically active compounds remains a significant focus in green chemistry. This study aimed to synthesize 4'-hydroxy-4-nitro chalcone from 4-hydroxyacetophenone and 4-nitrobenzaldehyde using a grinding technique and then characterize the synthesized compounds. The 4'-hydroxy-4-nitro chalcone was synthesized via the Claisen-Schmidt grinding method for 45 minutes at room temperature. The grinding results were extracted with chloroform. The formed crystals were tested for purity by thin-layer chromatography (TLC), and further purification was carried out by recrystallization. The synthesized chalcone was characterized using FTIR, 1H-NMR, and 13C-NMR  spectroscopy. The chalcone was also tested for antibacterial activity using the disc diffusion method against Staphylococcus aureus and Escherichia coli. The results showed that 4'-hydroxy-4-nitro chalcone could be successfully synthesized from 4-hydroxyacetophenone and 4-nitrobenzaldehyde using the grinding technique, yielding orangish-white crystals with a 70.63% yield and a melting point of 173°C. Purity was confirmed by TLC, and structural characterization was achieved through FTIR, 1H-NMR and 13C-NMR spectroscopy. Antibacterial testing revealed that the synthesized chalcone produced a clear zone diameter of 9.27 mm against S. aureus and 27.88 mm against E. coli. These results indicate that the compound has relatively strong antibacterial activity against E. coli and relatively weak activity against S. aureus. This study demonstrates the effectiveness of the green synthesis method and provides valuable insights into the antibacterial properties of 4'-hydroxy-4-nitro chalcone

Abstract

ABSTRACT. In the past 5 years, research has reported that chemical sunscreen products pose risks of irritation and environmental impact, necessitating safer natural alternatives, such as eco-friendly sunscreen. This study aimed to formulate a natural sunscreen by combining Aloe vera gel with garlic-shallot peel waste extracts and evaluate their solar protection factor (SPF), physical stability, overall quality, and organoleptic-hedonic test. The Aloe vera and extracts of garlic and shallot peels were prepared using modified infusion and solvent extraction techniques. The sunscreen formulas were created in nine variations with different concentrations of natural ingredient combinations. SPF values were determined in vitro using UV/Vis spectrophotometry, and the physical stabilities were tested using the cycling method. Overall quality tests were performed using the method as described in the standard and requirements for sunscreen products in Indonesia (SNI 16-4399-1996), and the procedure for determining the organoleptic-hedonic test referred to the organoleptic and/or sensory testing instructions (SNI 01-2346-2006). The results showed that all nine formulations met most of the quality standards of sunscreen. However, the panelist preferred formulas without garlic and shallot extracts due to the prominent odor of garlic and shallot. Further studies will be performed by combining them with fragrances that panelists prefer to cover the deficiencies in unpreferred odors. Formulas with garlic and shallot peel extracts have ultra-protection SPF values, though their effectiveness decreased with increased Aloe vera concentrations. These results indicate that garlic and shallot peel waste have the potential as sustainable, environmentally friendly sunscreen ingredients with high UV protection capabilities. Keywords: Aloe vera, garlic peel, shallot peel, SPF, sunscreen

Abstract

Education for Sustainable Development (ESD) is an important approach to preparing younger generations to face global challenges such as environmental, social, and economic crises. Integrating ESD into science instruction is crucial because science provides the conceptual foundations and critical thinking skills needed to understand sustainability issues. Despite growing attention, implementation remains uneven and the literature is imbalanced across region, levels, and designs. This study examines trends, focus, and research gaps related to ESD in science education through a Systematic Literature Review (SLR) combined with bibliometric analysis. Data were obtained from the Scopus database using the keywords “education for sustainable development” and “science education,” which yielded 81 articles published between 2015-2025 and 46 articles were deemed eligible for analysis. Beyond thematic synthesis, the bibliometric maps reveal the field’s structure, temporal dynamics, and the peripheral positioning of several ESD integrations within science classrooms. The SLR results indicate that research on ESD in science education is dominated by qualitative studies focusing on environmental awareness and sustainable attitudes, leaving a limited evidence base to estimate causal impacts on science competencies and 21st century skills. There are gaps in the development of innovative ESD-based learning models, particularly at the elementary and secondary levels, as well as limitations in measuring 21st-century skills integrated with ESD principles. These findings highlight the need for further exploration of effective and contextual pedagogical approaches to implementing ESD in science education. Methodologically, the concurrent use of SLR and bibliometrics still uncommon in science education to adds depth and enhances interpretive validity.
