After conducting research using the experimental method on energy and its transformations, in Cycle I, 14 students achieved a passing grade and achieved the Minimum Completion Minimum (KKM) with a percentage of 56%, while 11 students received an incomplete grade, failing to achieve the KKM with a percentage of 44%. In Cycle II, the learning outcomes improved further, with 20 students achieving a passing grade with a percentage of 80%, and 5 students receiving an incomplete grade with a percentage of 20%.

This study investigates the effectiveness of an integrative learning model in improving Indonesian literature appreciation skills among high school students. A quasi-experimental design was employed, involving 120 eleventh-grade students from two public high schools in Jakarta, Indonesia. The participants were divided into two groups: the experimental group, which received instruction through the integrative learning model, and the control group, which followed traditional teaching methods. The integrative model was designed to combine language skills development—such as reading comprehension, vocabulary enrichment, and critical writing—with structured literary analysis focusing on themes, characterization, style, and cultural context. Data were collected using pre-test and post-test assessments to measure learning outcomes, observation sheets to monitor classroom activities, and student questionnaires to capture perceptions and engagement levels. The results indicated that students in the experimental group experienced a significantly higher improvement in literature appreciation skills compared to those in the control group (p < 0.05). They demonstrated enhanced abilities to interpret literary works, analyze narrative elements, and articulate critical responses to Indonesian contemporary literature. Observation data revealed that the integrative approach fostered more active participation, collaborative learning, and deeper reflection during classroom discussions. Moreover, student feedback highlighted increased motivation, enjoyment, and perceived relevance of literature learning to real-life experiences. These findings underscore the pedagogical potential of integrative learning models in secondary school literature education. By linking language proficiency with analytical and interpretative competencies, this approach not only strengthens students’ linguistic abilities but also cultivates their critical thinking, cultural awareness, and aesthetic appreciation. The study recommends the wider adoption of integrative methods in Indonesian high schools as an effective strategy for promoting meaningful and enduring engagement with literature.

The background of this study stems from the problem of low active student participation in class, which is largely caused by difficulties in understanding abstract science concepts. The CLIS model offers a learning approach that emphasizes active student involvement through a series of systematic learning stages. The method used is a literature review with a qualitative descriptive approach. Analysis was conducted on 25 articles from national and international publications. Each article was reviewed based on relevance, research methods, main findings, and the suitability of CLIS application in various science learning contexts. The results of the study indicate that CLIS has proven effective in improving students' understanding of science concepts, developing science process skills such as observation, classification, measurement, and hypothesis testing, and encouraging active student participation during the learning process. In addition, this model is also able to improve critical thinking skills through exploration activities, experiments, group discussions, and reflection on learning outcomes. The CLIS stages, which include exploring students' prior knowledge, introducing new concepts through experiments, strengthening understanding through discussions, and strengthening concepts through reflection, enable students to construct knowledge independently and meaningfully. Based on these findings, CLIS is considered relevant and can be an effective alternative learning model to improve the quality of science learning at various levels of education.

Education is a conscious and structured effort aimed at creating an environment and process that actively facilitates learners in developing their full potential. This includes nurturing their spiritual and moral values, self-control, intelligence, strong character, and essential life skills required for personal development and meaningful contributions to society, the nation, and the global community. At its core, education serves to empower students to realize and utilize their capabilities for future life challenges. It acts as a foundational medium through which younger generations acquire essential life skills, enabling them to integrate effectively into society. Moreover, education plays a pivotal role not only in the personal growth of individuals but also in the advancement of a nation. High-quality education is defined by its capacity to equip students with the competence to confront and resolve real-world problems. This notion becomes increasingly critical as learners transition from academic settings to the workforce and community life, where they are expected to apply their knowledge and skills practically. However, the success or failure of educational outcomes is largely determined by the curriculum. A well-designed curriculum should cultivate critical awareness and empower students to navigate complex social and professional environments. It should also promote creativity, critical thinking, and collaboration, which are essential skills in today’s rapidly changing world. Furthermore, education should not be viewed merely as a means to acquire knowledge but as a holistic process that fosters emotional intelligence and social responsibility. By integrating various disciplines and encouraging interdisciplinary learning, education can help students develop a broader perspective on global issues, such as climate change, social justice, and economic inequality. In addition, the role of educators is crucial in this process.  

The integration of digital technology in education serves as a strategic solution to enhance learning access, particularly for students in regions with limited educational infrastructure, such as Sorong City, Southwest Papua. This community service program was designed to introduce and provide training to junior high school students in the use of the Thunkable application as a tool for mobile-based learning media. Thunkable is a visual drag-and-drop platform that enables users to design functional mobile applications without the need for prior programming knowledge. The method employed in this activity is based on the Research and Development (R&D) approach using the 4D model, which consists of four stages: Define, Design, Develop, and Disseminate. In the Define stage, the needs and digital readiness of the target group were assessed. The Design and Develop stages involved creating a training module and conducting hands-on workshops where students were guided step-by-step to create simple educational apps. In the final Disseminate stage, the outcomes were evaluated and shared for broader use. The results of this initiative revealed high levels of enthusiasm among the participants. Students were actively engaged and demonstrated the ability to independently design simple learning applications by the end of the training. This indicates that the use of Thunkable not only increases students' digital literacy but also enhances their self-directed learning, creativity, and technological confidence. Overall, this activity illustrates the potential of mobile learning tools to support inclusive and adaptive education in remote communities. By equipping students with practical digital skills, it lays the foundation for long-term educational innovation and empowerment. Therefore, the use of Thunkable can be considered an effective and accessible alternative to foster meaningful learning experiences across diverse educational contexts.

This study focuses on the development of an interactive web-based learning platform for Proportional-Integral-Derivative (PID) control systems, aimed at addressing the conceptual challenges faced by electrical engineering students when learning PID through conventional teaching methods. Despite its foundational role in control theory, PID remains difficult to grasp without practical visualization and hands-on experimentation. To bridge this gap, the research introduces a practical and accessible platform that enhances conceptual understanding through real-time simulations and physical interaction. The proposed system integrates key hardware components including an ESP-32 microcontroller, DC motor, rotary encoder, BTS 7960 motor driver, and I2C LCD. The platform’s web interface is built using HTML, Tailwind CSS, and JavaScript, enabling intuitive user interaction. Motor response data is captured via the ESP-32 and transmitted to the web interface using the WebSocket protocol, allowing users to instantly visualize system behavior as PID parameters (Kp, Ki, Kd) are adjusted. This dynamic feedback mechanism enables students to observe changes in system characteristics such as rise time, overshoot, and settling time in real time. To evaluate the platform’s feasibility, practicality, and educational effectiveness, beta testing was conducted among electrical engineering students using Likert-scale questionnaires. The results demonstrated that users were able to successfully interpret the impact of PID tuning on system performance. The average evaluation score reached 75.13%, indicating strong agreement regarding the platform’s educational value and its effectiveness in enhancing learning outcomes. In conclusion, the study affirms that the developed web-based platform offers a feasible, engaging, and pedagogically effective alternative to traditional learning approaches. By combining interactive simulations with physical experimentation, the platform significantly improves students’ understanding of PID control systems.

This study aims to observe the phases of mitosis in the meristem cells of shallot roots (Allium cepa) through microscopic observation as part of the Cell Biology learning model. Mitosis is an important part of the cell cycle that plays a role in growth, tissue repair, and asexual reproduction in organisms. A deep understanding of the mitosis process is an important foundation in various branches of biology, including genetics, biotechnology, and histology. Shallot roots were chosen because they have actively dividing meristem tissue at the root tip,as well as a large and transparent cell structure that facilitates the staining and observation process. Preparation was carried out by soaking the onion roots in a solution of acetic acid and alcohol for fixation,then staining with acetocarmine acid so that the chromosomes are clearly visible. The process of crushing the root tip and pressing it on a glass object (squash method) was used to expand the observation area. A light microscope with a magnification of 400x and 1000x was used to identify the division phases. Observation results show the presence of all phases of mitosis, namely prophase (nucleolus and nuclear membrane begin to disappear,chromosomes condense), metaphase (chromosomes line up at the equator), anaphase (chromatids separate to opposite poles), and telophase (nuclear membrane and two daughter cell nuclei re-form). Visual documentation in the form of microscopic photographs and descriptive tables clarify the identification of these phases, thus facilitating student understanding.From a pedagogical perspective, this microscopic practicum-based learning has been proven to improve students' observational skills, laboratory skills, and conceptual understanding of cell division. Students not only memorize theories, but directly experience the scientific process through exploration and discussion of observation results. Evaluation of learning outcomes is carried out through post-practicum quizzes and student worksheets, showing an increase in understanding scores of more than 30%.
