Abstract

Solid soap is a type of skin cleanser formulation that functions to remove dirt, oil, and microorganisms such as bacteria. This study aims to formulate a solid bath soap containing ethanol extract of "pisang mas" banana peel (Musa acuminata) and to evaluate its antibacterial effectiveness against Staphylococcus aureus. The "pisang mas" banana peel was selected due to its content of active compounds such as flavonoids, saponins, and tannins, which are known to possess antibacterial properties. The extraction process was carried out by maceration using 96% ethanol, yielding an extract with a yield of 34.4%. The solid soap was formulated with four variations of extract concentrations: 0% (control), 8%, 10%, and 12%. Each formulation was subjected to physical quality tests including organoleptic properties, moisture content, foam height, and pH, in accordance with the Indonesian National Standard (SNI 06-3532-1994). Antibacterial activity was evaluated using the disc diffusion method against Staphylococcus aureus. The results demonstrated that all formulations met the quality standards for solid soap. The antibacterial test showed that extract concentrations of 8%, 10%, and 12% produced inhibition zones of 7.8 mm, 9 mm, and 16 mm, respectively, while the negative control showed an inhibition zone of 8.2 mm. These data indicate that increasing the concentration of "pisang mas" banana peel extract in the solid soap formulation positively correlates with enhanced antibacterial activity. The 12% concentration exhibited the strongest antibacterial effect. Therefore, ethanol extract of "pisang mas" banana peel shows potential as a natural active ingredient in antibacterial solid soap formulations.

Abstract

Misconceptions about atomic structure and subatomic particles are a systemic issue in chemistry education, hindering the understanding of advanced concepts and limiting critical thinking. This study aims to identify common misconceptions, explore their root causes, and propose effective corrective strategies. A literature review of 20 peer-reviewed articles was conducted using thematic analysis across three main focuses. Findings reveal that deterministic views of the Bohr model, confusion over technical terms, and misinterpretation of symbolic representations are the most prevalent misconceptions. These stem from unadaptive teaching methods, cognitive limitations, and misleading visuals. Effective remedies include cognitive conflict, dynamic visualizations, and historical-metacognitive approaches to support conceptual change and deepen scientific understanding.

Abstract

This study aims to determine the relationship between playing victim potential and students' critical thinking skills on chemical bonding material. This study uses a correlational quantitative method with a survey design. The sample consisted of 32 Biology Education students class of 2023 who programmed the Basic Chemistry 1 course, randomly selected. Data were collected through a questionnaire to identify perpetrators and victims of playing victim, as well as essay questions to measure critical thinking skills. The results showed that 27 students were potential perpetrators of playing victim and 5 students as victims. Pearson correlation analysis showed a significant negative relationship between potential playing victim and critical thinking ability (r = -0.681, p < 0.01). This finding reflects the importance of character education and mental strengthening of students to prevent deviant thinking patterns that hinder cognitive development. In the future, the integration of affective education in chemistry learning becomes increasingly relevant.

Abstract

Cassava leaves (Manihot esculenta Crantz) are known to contain various bioactive compounds such as flavonoids, tannins, saponins, and alkaloids. This study aimed to compare the effectiveness of three extraction methods maceration, digestion, and Soxhlet extraction in producing stock solutions of cassava leaf extract. A total of 5 grams of cassava leaf simplicia was extracted using methanol 96% (maceration), distilled water (digestion), and methanol 99.9% (Soxhlet). The extract yield was measured by evaporating 1 mL of filtrate and weighing the residue. The results showed that the Soxhlet method produced the highest concentration of 0.085%, followed by digestion (0.0132%) and maceration (0.0106%). Soxhlet extraction was more effective due to its continuous solvent circulation at elevated temperatures and higher solvent volume, resulting in a more efficient extraction of active compounds from the cassava leaves.

Abstract

This research aims to optimize the extraction method for natural compounds from the Moringa oleifera plant in order to obtain the most effective method for isolating bioactive compounds that have the potential to be applied in natural cosmetic products. Four extraction techniques were compared in this study, namely ultrasonic extraction, maceration, digestion, and soxhletation, using methanol, n-hexane, and water as solvents. The highest yield was obtained from the ultrasonic assisted extraction (UAE) method with a concentration of 2.4% (w/v) this method is carried out for 60 minutes using a frequency of 60 kHz, followed by soxhletation at 0.8% (w/v). Phytochemical tests showed the presence of flavonoids, tannins, alkaloids and terpenoids, while saponins were not detected in several solvent systems due to differences in polarity. These results show that the UAE method is the most efficient technique for isolating active compounds from Moringa leaves, so it has the potential to be used in the formulation of natural cosmetic preparations, especially as an antioxidant in skin care.

Abstract

Chemistry learning requires students to develop the ability to comprehend complex and abstract concepts through the interconnection of macroscopic, microscopic, and symbolic levels of representation. However, numerous studies have revealed that students often struggle to integrate these three levels, resulting in a fragmented and mechanical understanding of chemical concepts. One effective pedagogical approach to address this issue is the use of multiple representation-based instructional media, which enables the presentation of chemical concepts through various interconnected forms of visualization and symbolization. This study aims to examine the effectiveness of multiple representation-based learning media in enhancing students’ conceptual understanding in chemistry education. The research employed a systematic literature review (SLR) method by collecting and analyzing scientific articles from Google Scholar, SINTA, and ERIC databases using the keywords “multiple representation” and “chemistry learning.” Based on the screening process, 15 relevant articles published between 2018 and 2023 were selected for in-depth analysis. The selected studies were reviewed descriptively and comparatively, focusing on research outcomes, methodologies, and their contributions to improving the quality of chemistry learning. The review findings indicate that the use of multiple representation-based media—such as animations, augmented reality (AR), electronic modules, and interactive multimedia—has proven effective in improving conceptual understanding, critical thinking skills, creativity, and students’ learning motivation. Moreover, such media facilitate diverse learning styles and reduce misconceptions regarding chemical phenomena. In conclusion, multiple representation-based instructional media demonstrate high effectiveness in fostering deep and contextual understanding of chemistry concepts and hold great potential as an innovative learning strategy for 21st-century education.
