Abstract

The demand for adaptive graduates in the Society 5.0 era necessitates the enhancement of Higher-Order Thinking Skills (HOTS). However, this is constrained by a lack of innovative teaching materials for pre-service science teachers at the Islamic University of Lamongan. This research aims to develop and assess the feasibility and effectiveness of a STEAM-based module designed to improve HOTS (analytical, critical, and creative thinking). Employing a 4D model of Research and Development (R&D), the product was validated by six experts and trialled with 25 students using a one-group pretest/posttest design. Data were analyzed using feasibility percentages and N-Gain scores. The results indicated that the module was declared "Very Feasible" by the experts, with scores of 88% for material content, 85.8% for language, and 90% for media. The module's implementation proved effective, achieving an average N-Gain score of 0.78 (categorized as "High"). This included improvements in creative thinking (N-Gain 0.85), critical thinking (N-Gain 0.78), and analytical thinking (N-Gain 0.69). Furthermore, the module received a highly positive response from students (89.2%). Therefore, this STEAM-based learning module is proven to be a valid and effective practical solution for enhancing the multiple dimensions of HOTS among pre-service teachers and can serve as a model for developing instructional materials in higher education.

Abstract

The world's dependence on fossil fuels has caused energy crises and environmental pollution, making renewable energy a crucial solution to develop. This study aims to analyse the effect of blade number variation on current and voltage in a simple waterwheel system. A quantitative correlational design was used to measure the relationship between the number of blades and the resulting electric current and voltage. The experiment used an educational water turbine generator kit, a digital multimeter, a stopwatch, a beaker, and supporting tools. The procedure involved three stages: assembling the turbine kit, measuring current and voltage across four blade variations, and calculating water flow using a beaker and stopwatch. Blade variations tested were 8, 6, 4, and 2, with each configuration measured four times for accuracy. The results showed a direct correlation between the number of blades and the generated current and voltage. Reducing the blade count from 8 to 2 resulted in a 19.05% decrease in current (from 13.02 A to 10.54 A) and a 52.63% drop in voltage (from 0.38 V to 0.18 V). A key challenge during the experiment was the fluctuating water flow rate, which made it difficult to maintain a perfectly constant flow. Therefore, the flow rate was approximated using the discharge formula and considered relatively stable. This experiment confirms that increasing the number of blades enhances energy conversion efficiency. In conclusion, mechanical energy directly influences electrical output, with blade number being a key factor. Future studies should explore variations in blade design, materials, and water flow control for optimal micro-hydro efficiency.

Abstract

Fly ash and glass waste can pose a significant environmental problem, as they cannot naturally decompose in the environment. This occurs due to the presence of pozzolan and silica in the waste. The purpose of this study is to categorize lightweight concrete and evaluate its properties, including density, compressive strength, and water absorption when incorporating additional fly ash and glass waste. This research uses experimental methods in the laboratory with a total of 72 samples with dimensions (25x25x50) mm in the form of blocks. Concrete samples were divided into two variations of storage duration, namely 21 days and 28 days, and given the same treatment and testing. The fly ash mixture variations used in this study were 0%, 20%, 40%, and 60%, with each variation consisting of 3 samples. The results obtained in this study indicate that, when viewed in terms of age, concrete with a storage period of 28 days exhibits better quality than concrete with a 21-day storage period. Based on the density value, both 21-day-old and 28-day-old concrete samples fall within the quality category of lightweight concrete, as per category A. When viewed from the compressive strength value, 21-day-old and 28-day-old concrete are of C quality. Regarding water absorption, the best value is achieved by the concrete mix with a 20% fly ash content and an 11% water absorption rate. When compared with concrete samples that do not contain fly ash, it is known that the test results on concrete samples without fly ash (0%) have higher compressive strength and density values, and the percentage of water absorption is by SNI standards.

Abstract

There is a strong belief in society that religion and science are two entities that cannot be reconciled. They are separate from one another and have their domains. Integration is the keyword for discussing the relationship between science and religion. The integration of science and religion can be achieved by taking the philosophical core of fundamental Islamic religious sciences as a paradigm for future science. This integration process can be seen as the Islamisation of science as part of the Islamisation of civilization. One example of this integration can be seen when discussing one branch of science, namely physics, about Islamic studies. In this case, one topic is taken from the First Law of Thermodynamics. Thermodynamics is the science that discusses heat and its changes. Heat and its changes have been explained in the Qur'an, as stated in the words of Allah SWT in Surat Al-A'raf, verse 52. For example, the source of heat energy has been explained in Surat Yaasin, verse 80, and Surat Yunus, verse 5, which state that fire is the source of heat. In its transformations, according to the First Law of Thermodynamics, this heat energy can change into changes in internal energy and work. Changes in internal energy occur due to an increase in the system's temperature after heat energy is added, while work arises due to a change in the system's volume after heat energy is added. As an illustration of the First Law of Thermodynamics, let us imagine a balloon. If the balloon is heated, the air particles inside the balloon will experience an increase in temperature. It is the nature of a particle that when its temperature increases, its energy also increases. This increase in energy is what we call an increase in internal energy. Since the internal energy of the gas particles inside the balloon increases, there will be more energy for the gas particles inside the balloon to move and collide with the walls of the balloon. As a result, the volume of the balloon will increase, and work will be done. If the elasticity of the balloon can no longer withstand the collisions of the gas particles inside it, the balloon will burst.

Abstract

Physics learning in senior high schools often faces challenges due to monotonous teaching methods and a lack of interesting media, resulting in low student interest and learning outcomes. This study aims to determine the effect of implementing the Problem-Based Learning (PBL) model supported by Powtoon-based assessment media on students' physics learning outcomes. Powtoon provides visual animations that can improve students' conceptual understanding. This study employed a quasi-experimental method with a post-test only control group design. The subjects were 72 eleventh-grade students at Arjasa State High School, randomly divided into 36 students in the experimental group and 36 students in the control group. The independent variable in this study was the PBL model with Powtoon media, the dependent variable was students' physics learning outcomes, and the control variables were the same topic and duration of instruction. The instrument used was a test consisting of essay questions. Data analysis was conducted using an independent sample t-test with a significance level of 0.05. The results of the study indicate a significant difference between the learning outcomes of students in the experimental group and the control group, with the experimental group achieving higher scores. Therefore, it can be concluded that the implementation of the PBL model with Powtoon as an assessment medium has a positive effect on students' physics learning outcomes. This approach can be used by teachers to enhance students' conceptual understanding and engagement in physics learning.
