Abstract

This study was motivated by students' difficulties in understanding the classification of living things, monotonous science learning, and the limited use of learning media at SMP Negeri 2 Samarinda. The study aimed to determine the validity, practicality, and effectiveness of Genially-based learning media integrated with Dayak Kenyah local wisdom for seventh-grade students. The research employed the Research and Development (R&D) method using the 4D model (Define, Design, Develop, and Disseminate). Data were collected through validation sheets, practicality questionnaires, activity observation sheets, and learning outcome tests. The results showed that the learning media achieved a very valid category with an Aiken’s V value of 0.897, a very practical category with an Aiken’s V value of 0.876, and a very feasible category with a percentage of 86.6%. The media was also proven effective, as indicated by an average student activity score of 92%, a paired sample t-test significance value of 0.000, and an N-Gain score of 0.41, which falls into the moderate category. Therefore, the Genially-based learning media integrated with Dayak Kenyah local wisdom is suitable for use in science learning on the topic of the classification of living things.

Abstract

From the past until now, weed control using synthetic herbicides has remained the primary method. The use of synthetic herbicides in modern agricultural processes still has negative impacts on the environment, health, and weeds, thereby potentially causing weed resistance. Therefore, planting herbal bioherbicides is a more environmentally friendly method of weed control. Sorghum (Sorghum bicolor L. Moench), in particular, has allelopathic exudates that are very troublesome for weeds. This study focused on analyzing the chemical allelopathy of sorghum root extracts and identifying candidate bioherbicide compounds in the roots using Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Sorghum was extracted using a cold maceration method obtained from a mixture of solvents with different configurations. Then, through GC-MS, the solvents were extracted, and the compounds were separated. As a result, through GC-MS analysis, 20 compounds were identified, most of which were detected in the steroid, sterol, and fatty acid derivative groups. The most prominent compounds detected were 4, 22-stigmastadien-3-one (20.74%); stigmasterol (total 16.47%); cholest-4-en-26-oic acid, 3-oxo- (11.68%); and 9-octadecenamide (Z) (7.69%). Several polar compounds, such as 9-octadecenamide (Z) and cyclohexanol derivatives, exhibited excellent capabilities. Therefore, sorghum root extract contains allelochemical compounds that have the potential to be sustainable and environmentally friendly bioherbicides.

Abstract

This study aims to analyze the cognitive level demands and science process skills represented in the 2025 senior high school Physics Academic Competency Test (TKA) simulation questions based on the national assessment framework. This research employed a descriptive qualitative approach using content analysis on a dataset of 20 Physics TKA simulation questions. The analysis instrument was developed based on the Physics TKA assessment framework, categorizing items into three cognitive levels (understanding, application, and analysis-evaluation) and four indicators of science process skills (observing, questioning and predicting, planning and conducting investigations, and analyzing and communicating data). The results show that the cognitive demands of the simulation questions were dominated by the application level (40%), followed by analysis-evaluation (35%) and understanding (25%). In terms of science process skills, all items involved observing and questioning-predicting skills (100%). However, analyzing and communicating data appeared in 20% of the items, while planning and conducting investigations was not identified in any item. This study is limited to simulation questions and therefore does not represent the characteristics of the operational Physics TKA items. Further research is needed to analyze the official Physics TKA 2025 questions to obtain a more comprehensive understanding of cognitive demands and science process skills, as well as to examine their consistency with the assessment framework of TKA.

Abstract

PT. X is a domestic pharmaceutical manufacturer producing pharmaceutical raw materials, specifically sodium chloride (NaCl) with a purity level ranging from 99.0% to 100.5%. The government’s pharmaceutical self-sufficiency program has intensified competition, prompting the need to evaluate factors influencing customer loyalty. This study aims to examine the effects of compliance image, product quality, and service quality on customer satisfaction and their implications for customer loyalty toward PT. X’s NaCl products. A quantitative research approach was employed, and the data were analyzed using SEM-PLS (SmartPLS). The results indicate that compliance image does not significantly affect customer satisfaction (p = 0.143), while product quality has a significant effect (p = 0.000). Service quality does not significantly affect customer satisfaction (p = 0.337). Furthermore, compliance image (p = 0.552) and service quality (p = 0.212) do not significantly influence customer loyalty. Product quality, however, has a significant effect on customer loyalty (p = 0.000). Indirect effect analysis shows that customer satisfaction mediates only the relationship between product quality and customer loyalty (p = 0.029), indicating a partial mediation effect. These findings suggest that product quality is the primary determinant of both customer satisfaction and loyalty. Therefore, PT. X should prioritize maintaining and enhancing product quality while continuing to strengthen compliance image and service quality as part of its business strategy to retain and expand its existing customer base.

Abstract

This study aims to analyze the effect of the Project-Based Learning (PjBL) model on the learning motivation of eighth-grade students regarding the food test topic. A quantitative approach with a quasi-experimental design was employed, involving two classes: an experimental group implementing PjBL and a control group utilizing the direct instruction method. Data were collected through motivation questionnaires and observation sheets during the learning process. The results indicate that the implementation of PjBL significantly enhances student motivation, as evidenced by the difference in post-test mean scores, where the experimental group scored 114 compared to 103 in the control group. These findings are further supported by observation data, showing a mean score of 120 for the experimental group and 71 for the control group. This research contributes to the development of effective and relevant teaching methods in science education. In conclusion, the PjBL model serves as a viable alternative to foster student engagement and enthusiasm in learning.

Abstract

This study aims to analyze the profile of students' metacognitive skills in colloid material assisted by POGIL inquiry-based E-LAPD in high school. This type of research uses a preliminary research method, namely data collection using instruments in the form of student questionnaires, teacher interviews, and written tests on metacognitive skills in colloid material. The data obtained were analyzed qualitatively and quantitatively descriptively. This study was conducted on 26 students at SMAN 19 Surabaya. Based on the results of the initial metacognitive skills test, it was found that the metacognitive skills of the 26 students were still lacking, with a percentage of 51% for planning, 11% for monitoring, and 46% for evaluation. Based on the questionnaire results, it was found that 96.2% of students considered colloid material difficult to understand because of the dominance of memorization activities and the presence of difficult terms. Based on the results of an interview with one of the chemistry teachers at SMAN 19 Surabaya, it was stated that E-LAPD was only used during practical work. Therefore, students' metacognitive skills are still low, so they can be developed through the application of POGIL inquiry-based E-LAPD. Thus, the initial results of this study provide an overview that the integration of POGIL inquiry-based E-LAPD learning media is very necessary to improve students' metacognitive skills.

Abstract

This study aims to produce a contextual laboratory practice in optics by analyzing the variations of fixatives in clove natural dye on the absorption of sunlight by colored fabrics. The background of this research lies in the limited optics experiments in schools, which often cause students to struggle in understanding the relationship between color, wavelength, and light energy, thus leading to misconceptions. The method employed was an experimental design with a posttest-only control, in which cotton fabrics were soaked in clove extract with three types of fixatives, namely alum, lime, and ferrous sulfate. The light absorption data were measured using a lux meter, then analyzed descriptively and statistically using one-way ANOVA. The findings indicated significant differences among the types of fixatives. Fabrics treated with alum fixative produced a bright yellow color with the highest absorption (113.7 Cd), followed by lime (69.5 Cd), while ferrous sulfate produced a deep blue color with the lowest absorption (16.22 Cd). This phenomenon can be explained through the concepts of light absorption, wavelength, and photon energy, in accordance with the Beer–Lambert law. This study demonstrates that clove natural dye with fixative variations can serve as a contextual, simple, and relevant laboratory medium aligned with the deep learning approach.

Abstract

Traditional culinary practices often involve physics processes that can be interpreted through scientific principles, yet these phenomena are rarely explored as contextual learning resources in physics education. This study aims to identify and analyze physics concepts embedded in the traditional production of bakpia, a well-known local pastry from Yogyakarta, Indonesia. The research employed a qualitative descriptive approach through direct observation and documentation of the dough mixing and roasting stages in a local bakpia production setting. The observed processes were then analyzed using fundamental physics concepts, particularly in the domains of mechanics and heat transfer. The results indicate that the dough mixing stage reflects principles of rotational motion, pulley transmission, angular velocity, frictional interaction, and mechanical power, while the roasting stage demonstrates multiple heat transfer mechanisms, including conduction, convection, and radiation. These findings reveal that traditional bakpia production inherently embodies scientific principles that can be explained through physics concepts. The study highlights the potential of local culinary practices as meaningful contextual resources for physics learning, contributing to the development of culturally relevant and context-based science education.
