Abstract

This study investigates the effectiveness of Android-based Augmented Reality (AR) in enhancing students' learning motivation in science. Using a quasi-experimental design, two groups were involved: a control group, which was taught using conventional methods, and an experimental group, which used AR media. The research sample consisted of 42 high school students, divided into two groups of 21 each. Data were collected through pretests and posttests, as well as a motivation questionnaire adapted from the ARCS model (Attention, Relevance, Confidence, Satisfaction). The results revealed a significant difference in motivation between the two groups, with the experimental group showing an average posttest score of 84.11, compared to 61.72 in the control group. The t-test showed a significant difference (p = 0.001), and N-gain analysis demonstrated that the experimental group had a higher N-gain (77.59%) compared to the control group (56.56%), indicating the effectiveness of AR. Additionally, the experimental group showed significant improvements in attention and satisfaction. This study concludes that Android-based AR is an effective tool for increasing student motivation in science, and recommends further research on its use in other subjects with larger samples.

Abstract

This study aims to identify students' reasoning abilities and learning difficulties related to Newton's Laws through a systematic literature review using the PRISMA method. The review analyzes seven scientific articles published between 2020 and 2024 in SINTA-accredited journals, international conference proceedings, and Scopus-indexed sources. The findings indicate that students’ reasoning abilities regarding Newton's Law are still low, with an average conceptual understanding of only 33.3%. Common difficulties faced by students include interpreting Newton's First Law (inertia and constant velocity), understanding the relationship between force, mass, and acceleration in the Second Law, and the action-reaction principle in the Third Law. These difficulties are generally caused by the abstract nature of the concepts and students’ weak logical reasoning skills. The review also highlights the need for effective instructional strategies. Contextual teaching, problem-solving-based learning models, and metaphorical thinking approaches are proposed as potential solutions. These strategies are considered effective in enhancing students’ conceptual understanding and scientific reasoning abilities when implemented appropriately. The findings provide valuable insights for educators to design more targeted instructional interventions and contribute to improving learning outcomes in physics education, particularly in Newtonian mechanics.

Abstract

This study aims to analyze the factors influencing customer satisfaction and loyalty at PT. PLN (Persero) ULP Tanjung Morawa using the Structural Equation Modeling (SEM) approach. A quantitative method was applied by distributing structured questionnaires to 150 customers selected through purposive sampling. The analysis was conducted using SmartPLS version 3.0. The results indicate that customer satisfaction has a significant positive effect on customer loyalty. Furthermore, perceived service quality and perceived value significantly influence customer satisfaction, while trust has a strong and significant effect on customer commitment. However, trust does not directly affect customer loyalty. These findings suggest that improving service quality and building trust are essential strategies to enhance customer satisfaction and commitment, which in turn foster customer loyalty. The study provides practical insights for PT. PLN to refine its customer relationship strategies in response to competitive service demands.

Abstract

Addressing many of today’s global challenges requires solid understanding of the different geologic processes that operate in and shape our planet. As such, Earth science has been included in the national science standards of many countries, including the Philippines. To describe the status of scholarly work in this discipline, one can draw insights from the systematic analyses of published research outputs, such as journal articles. This paper presents the state of research on Earth science education in the Philippines from 2013 to 2022. Google Scholar searches and a survey of locally published journals yielded 28 open-access research papers for analysis. Inclusion criteria were based on previous bibliometric studies conducted in other subfields of science education. Data collection was accomplished from January to November 2024. Most research studies focus on learning conceptions and adopt a quasi-experimental research design. The most frequently investigated demographic group are high school students and sample sizes vary from 30 to more than 500. Researcher-made tests and questionnaires were widely used as data collection tools, while inferential statistical methods were commonly utilized in data analysis. Implications to Earth science education research and recommendations to expand the scope of similar studies in the future are also discussed.

Abstract

Biological literacy is essential for students to understand and apply biological concepts. This study aims to develop an e-book on the ecosystem and examine its effect on the biological literacy of Grade X students at SMA Muhammadiyah 4 Jakarta. The research adopted the Hannafin & Peck development model. Based on the needs analysis, students require learning media that is portable and visually engaging. The created e-book has instructional texts that cover four areas of biological literacy: nominal, functional, conceptual, and procedural. It also has AKM-style questions that require reasoning and structured practice exercises. Feasibility testing covered aspects of construction, material, and language, with an average score of 3.4 in the valid category. The effectiveness test showed an increase in students’ biological literacy, with pre-test and post-test average scores of 50.05 and 80.11, respectively. The N-gain score was 0.62 (categorized as medium), and the effect size was 2.98 (categorized as a strong effect). Although effective, the e-book has limitations, such as the inability to complete quizzes directly within the e-book and the requirement of an internet connection to access external practice features. These limitations are recommended to be addressed in future research and development.

Abstract

This study was conducted to determine the secondary metabolite compounds and evaluate the antimicrobial activity of ethanol extract of jamblang stem bark (Syzygium cumini). The method used in this research is experimental method. The extraction was carried out using the maceration method with 96% ethanol as the solvent. Secondary metabolite compounds of the extract samples were analyzed using a Gas Chromatography-Mass Spectrometry (GC-MS). Antimicrobial activity of the extract against Cutibacterium acnes, Staphylococcus aureus, and Candida albicans using disc diffusion method tested on MHA (Mueller Hinton Agar) media with extract concentrations of 40%, 60%, 80%, and 100%.  Each experiment was repeated three times to ensure validity. The results revealed that the extract have dominant compounds such as 7-Tetradecenal (Z), Octadecanoic acid, and n-Hexadecanoic acid. The antimicrobial test showed that the highest inhibition zones were 7.45 mm for C. acnes, 8.04 mm for S. aureus, and 4.60 mm for C. albicans at 100% extract concentration. The inhibition zones increased with higher extract concentrations, indicating a dose-dependent relationship. Compared to the positive control results (20.70 mm; 22.29 mm; and 18.62 mm) the extract showed moderate antimicrobial activity. These findings suggest that jamblang stem bark extract has potential as a natural antimicrobial agent.

Abstract

Magnetohydrodynamics (MHD) studies the relationship between electromagnetism and fluid mechanics, a concept with various practical applications, including marine propulsion systems and electromagnetic pumps. This study aims to optimize a simple MHD system to improve the performance of fluid rate measurement based on electromagnetic principles. Optimization is carried out through the analysis of the influence of variations in several system characteristics, namely the given electrical voltage, the distance between electrodes, the length of the electrode, and the salinity of the saltwater. The method employed is experimental, utilizing a simple MHD system design that enables the quantitative observation of changes in the speed of saltwater resulting from the interaction between magnetic and electric fields. The speed of saltwater is measured using a visual approach with the Tracker analysis application. The results showed that increasing the voltage and salinity of the saltwater, as well as decreasing the electrode length or the distance between electrodes, all contribute to increasing the speed of saltwater flow. In other words, each parameter makes a significant contribution to fluid dynamics, thereby allowing for the optimal configuration of the MHD system. The findings in this study are expected to serve as the basis for the development of simple MHD-based fluid rate measurement instruments that are efficient and applicable, enabling a concrete illustration of electromagnetic theory and fluid dynamics.
