Abstract

This study aims to analyze the effect of a green chemistry project-based discovery learning model on students' learning outcomes and collaboration skills in acid-base learning. This study used a quasi-experimental design with a pretest-posttest control group design in two randomly selected classes. The research instruments included a learning outcome test (pretest-posttest) and a collaboration skills observation sheet. Data were analyzed using the N-Gain test, independent sample t-test, and effect size calculation. The results showed that the N-Gain value of the experimental class was 0.66 ± 0.15, higher than the control class's 0.44 ± 0.14. Hypothesis testing showed a sig. <0.05 for learning outcomes and collaboration skills, indicating a significant difference between the two classes. In addition, the effect size values ​​obtained were 0.61 (moderate category) for learning outcomes and 0.96 (high category) for collaboration skills. These findings prove that the green chemistry project-based discovery learning model is effective in improving students' learning outcomes and collaboration skills, and have implications for the development of more contextual and collaborative chemistry learning.

Abstract

The Javan rhinoceros (Rhinoceros sondaicus) is an endemic Indonesian animal that is critically endangered and has distinctive visual characteristics, such as a sturdy body, thick, folded skin, and dark gray color. These visual characteristics have the potential to be a source of inspiration in creating fantasy makeup through body painting techniques. This study aims to develop fantasy makeup on clay sculptures inspired by the Javan rhinoceros, as well as to assess the validity of the instrument and the feasibility of the resulting work. This study uses a research and development method with the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. Data were collected through instrument validation sheets by experts and work feasibility assessment sheets, then analyzed using Aiken's V and descriptive percentages. The results showed that the assessment instrument had an Aiken's V value of 0.81 with a very valid category, while the developed work obtained an average feasibility of 90.97% with a very feasible category. These results indicate that the application of body painting techniques to clay sculptures is able to produce fantasy makeup works that meet the aesthetic, visual, creativity aspects, and suitability with the character of the object of inspiration. The implications of this research indicate that visuals of Indonesia's endemic fauna can be utilized as a source of creative ideas in developing works and teaching beauty art.

Abstract

This study aims to analyze the sensitivity of prospective reserves for whole life insurance to BI-Rate fluctuations based on the Indonesian Mortality Table (TMI) IV. The method used is quantitative, using secondary data in the form of a male population in TMI IV, assuming a certain entry age, a fixed sum insured, and a fixed annual premium. Three constant interest rate scenarios are applied: pessimistic, normal, and optimistic. Prospective reserves are calculated using the gross premium valuation method using commutation symbols. The results show that a decrease in interest rates significantly increases reserves, especially at the middle of the policy life, and results in a positive initial reserve indicating an immediate liability burden. Conversely, an increase in interest rates depresses reserves to a negative value, reflecting a capital surplus. The conclusion of this study is that BI-Rate fluctuations significantly impact the solvency of life insurance companies, necessitating a dynamic asset-liability matching strategy.

Abstract

Free radicals are a major cause of skin damage that can accelerate premature aging; therefore, the use of antioxidants, particularly from natural sources such as papaya leaves (Carica papaya L.), is essential due to their flavonoid, tannin, and polyphenol content. The application of antioxidants in a face mist formulation is considered practical as it is easy to use and provides a refreshing effect on the skin. This study aimed to evaluate the antioxidant activity of a face mist containing California papaya leaf extract using the DPPH method and to assess its physical characteristics. A quantitative experimental method with a post-test only design was employed using two formulations with different extract concentrations. The results showed that the IC₅₀ values of Formula I and Formula II were 2475.23 ppm and 812.14 ppm, respectively, indicating very weak antioxidant activity, although Formula II exhibited better performance. Physical evaluation revealed that both formulations were organoleptically stable and homogeneous; however, the pH values were below the acceptable skin range and the viscosity of Formula II was relatively high. In conclusion, the formulation demonstrates potential as a natural antioxidant product, but further optimization is required to improve its effectiveness and quality.

Abstract

This study aims to examine the effect of the time token learning model on improving students' comprehensive cognitive abilities and problem-solving skills on the topic of circles. This study was motivated by the suboptimal utilization of learning modules, as well as the lack of innovation in mathematics learning models that impact students' low engagement and thinking skills. The research method used was a quasi-experimental design with a pretest-posttest two treatment groups. The sample of the study was 45 eighth grade students. The research instrument was an essay test analyzed using N-Gain to measure improvements in comprehensive cognitive abilities and problem-solving, and MANOVA test to see differences between groups. The results showed that the application of the time token learning model was able to improve students' comprehensive cognitive abilities and problem-solving in the medium category. The N-Gain values ​​in large groups were 0.520 and 0.359, respectively, while in small groups were 0.558 and 0.342. However, the results of the MANOVA test showed that there was no significant effect of group size on both abilities. The main findings of this study indicate that the time token model is effective in improving students' abilities, but differences in group size (small and large) did not have a significant effect. This model also encourages active participation and equitable student involvement in mathematics learning.

Abstract

This research is motivated by the low mathematical literacy skills of students at SMPN 5 Medan. The low mathematical literacy skills are caused by several factors, namely conventional learning and the use of interactive learning media and technology that has not been utilized optimally. One effort that can be done to improve these skills is through the application of the Realistic Mathematics Education (RME) approach assisted by GeoGebra. This study aims to determine the effect of the RME approach assisted by GeoGebra on students' mathematical literacy skills in geometry material. This study uses a quantitative approach with a quasi-experimental method and a pretest posttest control group design. The research sample was determined using a purposive sampling technique, so that two classes were obtained as samples, namely class VIII-8 as a control class consisting of 30 students, and class VIII-1 as an experimental class consisting of 30 students. The research instrument was a mathematical literacy ability test given before and after treatment. Data analysis with hypothesis testing using an independent sample t-test. The test results obtained a t value = -3.718 with a sig. The value of 0.000 < 0.05 indicates that H0 is rejected and H1 is accepted. Therefore, it can be concluded that the GeoGebra-assisted RME approach has a positive and significant effect on students' mathematical literacy skills.

Abstract

Acne (Acne vulgaris) is a skin problem often caused by Propionibacterium acnes bacterial infection. Guava leaves (Psidium guajava L.) contain antibacterial compounds, but their use as facial cleansing cosmetic preparations in the form of micellar water has not been widely done. This experimental study aims to determine the feasibility of guava leaf extract micellar water preparations in inhibiting the growth of Propionibacterium acnes. The preparations were formulated into two variations of extract concentration, namely F1 (50%) and F2 (100%). The evaluation stage of the preparations included organoleptic tests, homogeneity, pH, viscosity, and antibacterial activity testing using the well method. The results of physical tests showed that both formulas were liquid in texture, dark brown in color, and had a distinctive odor of guava leaves. However, the preparations were proven to be inhomogeneous due to the presence of particle deposits. The average pH value of the preparations was classified as acidic and was below the physiological standard of the skin (<4.5) which was 3.05 for F1 and 3.19 for F2. Antibacterial testing showed weak inhibition (<5 mm), with an average F1 inhibition zone of 0.961 ± 0.0300 mm and F2 of 1.142 ± 0.0226 mm. One-way ANOVA analysis showed a statistically significant difference between the treatment groups (p<0.05). However, the preparation was not yet clinically effective, thus concluding that guava leaf extract micellar water is not yet suitable for optimal application due to the physical instability triggered by the high extract concentration and its inadequate ability to penetrate the complex cell wall of Propionibacterium acnes. Further research is needed to optimize the formulation of this preparation.
