Abstract

This study aimed to develop Powtoon animated videos for STEM-integrated physics learning and assess their impact on student learning outcomes. The Research and Development (R&D) method, using the ADDIE model, was employed to systematically develop and evaluate the instructional media. The study involved five phases: analysis, design, development, implementation, and evaluation. During the analysis phase, needs were identified based on observations of students' difficulties in understanding abstract physics concepts and their disengagement from traditional teaching methods. The videos were developed to integrate scientific, technological, engineering, and mathematical (STEM) concepts, focusing on simple machines such as levers and pulleys. Expert validation was conducted to assess the quality of the videos, and revisions were made accordingly. The implementation phase involved a pretest-posttest control group design with eighth-grade students from SMP Negeri 2 Watumalang. The experimental group used the STEM-integrated Powtoon videos, while the control group received traditional instruction. Data were analyzed using a t-test and N-Gain to measure the improvement in student learning outcomes. Results showed a significant improvement in the experimental group’s post-test scores, with an average N-Gain of 66.95%, categorized as moderately effective. The control group had a lower average N-Gain of 49.22%, categorized as less effective. The findings demonstrate that the Powtoon videos not only enhanced students' conceptual understanding but also increased their motivation and engagement in physics learning. These results suggest that integrating STEM principles into instructional media, such as animated videos, is an effective strategy for improving learning outcomes in physics. The study recommends expanding the use of such multimedia approaches across other STEM-related subjects to foster critical thinking and problem-solving skills in students.

Abstract

This study investigates the impact of integrating the scientific approach within the problem-based learning (PBL) model on students' creative thinking and design thinking skills, specifically in the context of physics education. The primary objective is to evaluate whether this combined approach significantly enhances these higher-order thinking skills compared to conventional teaching methods. A quasi-experimental design was employed with non-equivalent control groups, comprising two eighth-grade classes: an experimental group receiving the PBL model with a scientific approach, and a control group taught using traditional methods. Pretests and posttests were administered to assess the students’ creative and design thinking abilities. Data were analyzed using parametric statistical methods, including normality and homogeneity tests, followed by a paired t-test to evaluate the hypothesis. The results indicated that students in the experimental group showed significantly higher improvements in both creative and design thinking skills compared to the control group. Key dimensions such as comfort with uncertainty, attention to process, and confidence in creativity were notably enhanced in the experimental group. The findings suggest that integrating the scientific approach within PBL fosters an engaging and effective learning environment, promoting not only cognitive development but also collaboration, communication, and problem-solving skills. These results have important implications for educational practices, highlighting the value of adopting student-centered learning models to equip students with the critical skills needed for future challenges.

Abstract

This study investigates the effects of varying base materials, specifically coconut shell charcoal (ATK) and corncob charcoal (ABJ), on the characteristics of biobriquettes. The research employs an experimental method, analyzing the impact of different ATK and ABJ proportions on calorific value, ash content, moisture content, density, and combustion rate. The biobriquettes were produced by mixing coconut shell and corncob charcoal with 10% tapioca starch adhesive, molded into cubes, and dried. The results show that increasing the ATK proportion improves the calorific value, with the highest value of 10,640 calories in briquettes with 90% ATK. In contrast, higher ABJ content results in faster combustion rates but lower energy efficiency, with the lowest calorific value of 6,424 calories in briquettes containing 90% ABJ. The study also highlights that all biobriquettes meet Indonesian National Standards (SNI) for moisture content and calorific value, although only the 90% ATK sample meets the ash content standard. These findings suggest that coconut shell charcoal is a superior biomass material for producing high-performance biobriquettes, with a 90% ATK and 10% adhesive combination yielding the best overall results for sustainable energy applications.

Abstract

This study explores the effectiveness of the Contextual Teaching and Learning (CTL) model, enhanced by video, in improving students' learning outcomes and motivation, specifically in understanding complex physics topics like sound waves. Traditional teaching methods often struggle to engage students with abstract content, creating a need for innovative approaches that bridge theory with practical applications. The CTL model aims to make learning more meaningful by connecting academic material with real-world contexts. A quasi-experimental design with a pretest-posttest control group was employed, involving two randomly selected groups from 50 students at SMAN 1 Masbagik. The experimental group was taught using the CTL model with video assistance, while the control group followed conventional methods. Data collection included learning outcome tests and motivation questionnaires, analyzed using normality, homogeneity, and t-tests to evaluate differences between groups. Results showed that the experimental group achieved a significantly higher posttest average score (78.92) than the control group (74.20), indicating improved comprehension. Additionally, motivation scores in the experimental group averaged 83.5, categorized as "motivated," suggesting increased engagement. The t-test confirmed a statistically significant difference in learning outcomes, underscoring the effectiveness of video-assisted CTL in enhancing both comprehension and motivation. These findings support the integration of video within the CTL model as a valuable educational strategy to create a more interactive, engaging, and effective learning environment. This study offers insights into how technology-enhanced teaching models can address the challenges of modern education and better prepare students for real-world problem-solving.

Abstract

This research focuses on optimizing the binder percentage in organic waste-based briquettes to improve their calorific value and combustion rate. Conducted through experimental methods, organic waste such as sawdust, dry leaves, and branches were processed into briquettes using varying concentrations of tapioca starch as a binder (10%, 12.5%, 15%, and 17.5%). The experiment evaluated key performance metrics, including calorific value, combustion rate, moisture content, ash content, and briquette density. Results showed that the optimal calorific value (9,234 cal/g) was achieved with 10% binder, while the highest combustion rate (0.586 g/min) occurred at 15% binder concentration. These findings suggest that lower binder percentages result in higher energy efficiency, while higher binder content prolongs combustion. However, increased binder content also led to higher ash production, with the highest ash content recorded at 17.5% binder. The research highlights that balancing the binder ratio is essential for creating briquettes that are both energy-efficient and environmentally sustainable, offering a viable alternative to traditional fuels in Indonesia's pursuit of renewable energy solutions.

Abstract

The persistent issue of low critical thinking skills among students in physics education highlights the limitations of traditional teaching methods, which often emphasize memorization over analytical and evaluative thinking. This study investigates the impact of Case-Based Learning (CBL) on improving critical thinking skills, focusing on six indicators: interpretation, analysis, evaluation, inference, explanation, and self-regulation. Conducted at SMA Negeri 1 Kediri, Lombok, Indonesia, the study employed a quasi-experimental pretest-posttest control group design. The experimental group received CBL instruction, while the control group was taught using conventional methods. Data collection involved written essay tests scored using a rubric adapted from the Ennis-Weir Critical Thinking Essay Test, with results analyzed through both descriptive and inferential statistics. Descriptive analysis calculated means, standard deviations, and normalized gains (n-gain), revealing significant improvements in the experimental group across all critical thinking indicators, with n-gain scores categorized as high. Inferential statistical analysis using paired and independent sample t-tests confirmed significant differences in critical thinking skill development between the experimental and control groups. The findings demonstrate that CBL fosters critical thinking by engaging students in real-world scenarios, promoting collaboration, and encouraging reflective reasoning. This study concludes that CBL is an effective pedagogical strategy for addressing critical thinking deficiencies in physics education, bridging the gap between theoretical understanding and practical application. The implications suggest integrating CBL into curricula to enhance students’ cognitive skills, equipping them for academic and professional challenges. Future research should explore CBL’s long-term impacts and adaptability to various subjects and educational contexts, ensuring its broader implementation as a transformative teaching approach.

Abstract

This study employed classroom action research with the aim of enhancing students' physics problem-solving skills using Problem-Based Learning (PBL) supported by student worksheets (Lembar Kerja Peserta Didik/LKPD). The research targeted 10th-grade high school students focusing on the topic of Measurement. The methodology followed a cycle comprising four stages: planning, action, observation, and reflection. At the end of each cycle, evaluations were conducted using a validated test instrument consisting of four essay questions. The success criterion was set at a minimum of 70% of students achieving a mastery level, defined by a score of at least 65. During the pre-cycle phase, before applying PBL, the initial test results revealed no students achieved mastery, with an average problem-solving score of 54.67. Subsequently, two cycles of PBL implementation were carried out. In the first cycle, 15 students reached the mastery criterion, representing 41.17% improvement in problem-solving skills, with an average score of 63.75. Building on this progress, the second cycle was implemented, resulting in 29 students achieving mastery. This represented 80.05% of the class, categorized as a moderate improvement, with an average problem-solving score of 70.05. These findings indicate a significant enhancement in students' physics problem-solving abilities through the integration of PBL and LKPD. This approach effectively facilitated active student engagement and critical thinking, demonstrating its potential as an impactful instructional strategy in high school physics education.
