Enhancing Critical Thinking and Spiritual Attitudes through Qur’an-Integrated Solar System Learning in Pesantren-Based Madrasah Aliyah: A Quasi-Experimental Study
type: item
description: This study aims to examine the effectiveness of Qur’an-integrated solar system teaching materials in improving students’ spiritual attitudes and critical thinking skills. A quasi-experimental method with a pretest–posttest control group design was employed. The participants consisted of 105 students from two pesantren-based Madrasah Aliyah in Semarang and Kendal, divided into an experimental group (n = 51) and a control group (n = 54). The experimental group was taught using Qur’an-integrated teaching materials, while the control group used conventional materials. Data were collected through a validated spiritual attitude questionnaire and an essay-based critical thinking test. Data were analyzed using normalized gain and independent sample t-test. The results showed that the experimental group achieved a higher improvement in spiritual attitudes (g = 0.52, moderate) compared to the control group (g = 0.14, low). Similarly, critical thinking skills in the experimental group (g = 0.55, moderate) were significantly higher than in the control group (g = 0.16, low). Independent sample t-tests revealed significant differences between groups in critical thinking skills (t = -2.88, p = 0.006) and spiritual attitudes (t = 3.41, p = 0.001). These findings indicate that Qur’an-integrated teaching materials are effective in enhancing both affective and cognitive domains. This study contributes to the development of integrative physics learning that bridges scientific concepts and spiritual values in Islamic-based education.

Exploring Physics Concepts in the Moke Distillation: An Ethnoscience Study of the JA Mokeasa Village
type: item
description: This study aims to identify physics concepts in the moke refining process practiced by the community of Ja Mokeasa Village, Ende Regency, East Nusa Tenggara. Moke is a traditional beverage made from enau tree sap and holds important social and cultural value. This research employed a qualitative descriptive ethnoscience approach. Data were collected through two direct observations of the distillation process and in-depth interviews with two moke artisans, each lasting approximately 45–60 minutes. Data credibility was ensured through source and method triangulation by comparing observations, interviews, and documentation. Data analysis used the Miles and Huberman interactive model, including data collection, reduction, presentation, interpretation, and conclusion drawing. The findings reveal several physics concepts in the distillation process, such as temperature and heat, changes in states of matter, heat transfer mechanisms, and pressure relationships. The moke distillation process has the potential to be used as a contextual learning resource in science or physics education by integrating local wisdom with scientific concepts.

Analysis Absorbed Dose Sensitivity of 18F-FDG to Abdominal Organ Mass Variation Using MIRDcalc
type: item
description: 18F-fluorodeoxyglucose Positron Emission Tomography (PET) using ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) is widely used in nuclear medicine. Accurate estimation of organ absorbed dose is important for patient safety and protocol optimization. However, standard dosimetry methods based on reference computational phantoms may not fully represent individual anatomical variability, particularly organ mass differences that influence absorbed dose estimation.This study aimed to analyze the sensitivity of absorbed dose to abdominal organ mass variations for ¹⁸F-FDG. A computational dosimetry simulation study was performed using MIRDcalc and the ICRP 133 adult male reference phantom to evaluate simultaneous mass variations of six abdominal organs within a ±50% range. A quadratic relationship was found between mass change and average absorbed dose (R²=0.9928). Dose decreased by 8.5% at +20% mass and increased by 9.2% at −20% mass. The small intestine showed the highest sensitivity (S=−0.45). Organ mass variation substantially influences absorbed dose estimates in simulation-based ^18F-FDG dosimetry. Further studies incorporating patient imaging data are required for clinical validation.

Development of a Web-Based Interactive Multimedia Course with Feedback for Conceptual Understanding of Equilibrium and Rotational Dynamics
type: item
description: This study aims to determine the effectiveness of using web-based interactive multimedia with feedback on conceptual understanding of rotational equilibrium and dynamics. The data collection method used a quasi-experimental design with a pretest-posttest control group design. The sample used in this study were 30 students in the control class and 30 students in the experimental class, who had studied rotational equilibrium and dynamics. Data analysis techniques used descriptive statistics calculations, independent-sample t-tests, effect size, and N-Gain. The results of the independent-sample t-test obtained p = 0.000 <α = 0.05, indicating a difference in conceptual understanding between the control and experimental groups. The effect size value of d = 0.85 is categorized as high, meaning that the score of the group using web-based interactive multimedia significantly influenced students' conceptual understanding compared to the score of the group that did not use web-based interactive multimedia. Meanwhile, the N-Gain value of 0.31021 indicates that the increase in pretest and posttest scores is in the moderate to upper range. This indicates that the effectiveness of using web-based interactive multimedia programs with formative feedback can improve students' conceptual understanding.

A Needs Analysis for Developing a STEM-R Module on Renewable Energy to Foster MTs Students' Creative Thinking
type: item
description: In the context of 21st-century education, students are required to master a range of skills, one of which is creative thinking. This study conducted a needs analysis to guide the development of STEM-R-based teaching modules on the topic of renewable energy. Using a descriptive qualitative approach, data were collected through document analysis (the Ministry of Religious Affairs’ vision and mission, the curriculum, and textbooks) as well as semi-structured interviews with education stakeholders. The results reveal a significant gap: although the Ministry of Religious Affairs’ vision emphasises holistic education and religious character, existing science teaching materials have not explicitly integrated Islamic values. The religious dimension (R) is entirely absent from the topic of renewable energy, even though stakeholders consistently emphasise the urgency of madrasah-specific teaching materials that contextualise science from an Islamic perspective. This study concludes that a STEM-R module on the topic of renewable energy is urgently needed. These findings indicate both the need for and potential direction of module development, which could serve as a basis for the design of future teaching materials to align with the Ministry of Religious Affairs’ educational philosophy.

Efektivitas PjBL terhadap Hasil Belajar, Berpikir Kritis, dan Motivasi Mahasiswa Teknik Elektro pada Praktikum Fisika
type: item
description: This study aims to analyze the effect of Project Based Learning (PjBL) on physics learning outcomes, critical thinking skills, and learning motivation among Electrical Engineering students at Universitas Malikussaleh. A quasi-experimental design with nonequivalent control group pretest-posttest was employed. The sample consisted of 60 students divided into a control group (conventional learning, n=30) and an experimental group (PjBL, n=30). Data were collected through learning achievement tests, rubric-based critical thinking instruments, and Likert-scale motivation questionnaires. It should be noted that critical thinking and motivation instruments were administered only after the treatment; therefore, pre-intervention baselines for these two variables were not measured.Shapiro-Wilk normality tests indicated non-normal distributions in several variables; therefore, the non-parametric Mann-Whitney U test was applied. Results showed: (1) the mean N-gain of the PjBL group (63.53%) was higher than the control group (26.47%); (2) critical thinking scores of the PjBL group (M=3.49; Very High category) were significantly higher than the control (M=2.72; Adequate category); (3) learning motivation of the PjBL group (M=4.45; Very High) was significantly higher than the control (M=3.16; Adequate). All Mann-Whitney U tests yielded p<0.001 with rank-biserial correlation r=1.00 and very large Cohen's d effect sizes (d=4.05–5.84). These findings provide strong evidence that PjBL was associated with higher outcomes across all three variables compared to conventional learning in the context of engineering physics practicum, although the non-randomized design limits causal claims.

description: This study aims to develop computer-assisted FORBIS to facilitate the correction of students' conceptual understanding of dynamic fluid materials. This Research and Development (R&D) project utilized the Plomp development model, involving two physics lecturers and one physics teacher as expert validators. The subjects consisted of 36 eleventh-grade science students (12 male and 24 female students), with 31 students participating in the practicality test and 5 students involved in the effectiveness test. A stratified purposive sampling technique was employed to select the students for the product effectiveness test. The data collection instruments used were questionnaires and interview guides. This research produced a product named Formative Feedback with Isomorphic Multiple-Choice Questions (FORBIS) to help improve students' conceptual understanding and serve as a tool for independent learning. Based on the validity test, the results obtained were 96.5% (highly valid) for isomorphic questions, 95.7% (highly valid) for true-false questions, 96.5% (highly valid) for feedback, and 96.4% (highly valid) for the overall product. The result of the product practicality test by students was 93.9%, falling into the highly practical category. The effectiveness test was conducted through limited interviews with 5 students before and after using the product, which were analyzed using a descriptive-comparative method to determine changes in students' conceptual understanding. The interview results indicated a positive trend toward the improvement of students' understanding of physics concepts after using the product. Accordingly, this research has successfully developed a computer-assisted FORBIS that meets the criteria of being valid and practical, while also indicating a capacity to support students' conceptual understanding based on limited interview results.

Pengembangan Instrumen Kecemasan Belajar Fisika bagi Siswa SMA
type: item
description: Physics learning anxiety is an affective factor that can influence students’ readiness to learn, concentration, and academic achievement. This study aimed to develop a valid and reliable instrument to measure physics learning anxiety among senior high school students. The development procedure followed the stages of research and development (R&D), including preliminary study, construction of dimensions and indicators, item development, content validation by five experts, limited trial testing (N = 30), and large-scale testing (N = 150). Content validity was analyzed using the Content Validity Ratio (CVR) and Content Validity Index (CVI). Empirical validity was determined through corrected item–total correlation (r_it), while reliability was assessed using Cronbach’s Alpha. The results showed that the instrument demonstrated strong content validity, indicated by a high CVI value. Empirical testing revealed three items (25, 34, and 37) that did not meet the r_it ≥ 0.30 criterion and were therefore removed. The final instrument consisted of 37 items with very high reliability (α = 0.939). This instrument is suitable for use as a measurement tool for assessing physics learning anxiety among senior high school students.

Korelasi SST, OLR Terhadap Curah Hujan di Wilayah Pesisir Timur Sumatera
type: item
description: This study aims to analyze the influence of sea surface temperature (SST), outgoing longwave radiation (OLR), and the Indian Ocean Dipole (IOD) on rainfall dynamics in the peatlands of East Sumatra’s coast. Data from ERA5 (SST, OLR), BMKG (rainfall), and a calculated IOD index (1982–2024) were analyzed quantitatively using Python and Pearson correlation. Results show SST in the Indian and Pacific Oceans correlates significantly and positively with rainfall (r > 0.6; p < 0.05), confirming the dominant roles of IOD and ENSO. OLR exhibits a strong negative correlation (r < –0.7; p < 0.05), reflecting its inverse relationship with convective activity and rainfall. The IOD index is significantly correlated with rainfall variation, particularly during positive IOD events, which are linked to rainfall deficits and increased peat fire risk. This quantitative analysis provides a basis for predicting rainfall and mitigating peatland fires.

type: item
description: In this study, activated carbon from cassava peel waste has been synthesized, with the aim of analyzing its effectiveness in reducing BOD and COD levels in laundry wastewater. Activated carbon was synthesized through a carbonization process at various temperatures (250°C, 300°C, 350°C) for 1.5 hours, then chemically activated using 2% KOH and physically activated with microwaves. Morphological characterization using SEM, and adsorption effectiveness was tested with contact time variations of 0 and 5 days for BOD, COD, pH, and temperature parameters. The results of SEM characterization showed that the carbonization temperature of 300°C produced optimal micro and mesoporous pore structures without structural damage. Treatment with activated carbon from 300°C carbonization (sample A2) showed the best performance, with a decrease in BOD from 450 mg/L to 200 mg/L and COD from 21.7 mg/L to 3.72 mg/L. The pH and temperature values after adsorption also meet environmental quality standards, namely neutral pH (7) and temperature 25.7°C. Activated carbon from cassava peel waste has been proven to be effective as an environmentally friendly adsorbent for laundry waste processing.

Rekonfigurasi Antena Folded Dipole Mikrostrip Berbasis Laser Merah dan Microwave Multifunctional Analyzer (MMA)
type: item
description: With the increasing use of communication devices across various regions, antennas with stable signal performance are essential to ensure reliable information transmission. In this study, a microstrip folded-dipole antenna operating in the SHF band was developed using a reconfiguration mechanism based on a 650-nm red laser and metamaterial absorber (MMA). The initial antenna structure was designed and simulated in CST software with a target operating frequency of 9 GHz. Experimental results show that the antenna without a resonator exhibits an operating frequency of 13.77 GHz when the laser is off and 3.15 GHz when the laser is on. When integrated with the resonator, the operating frequencies shift closer to the simulation results, ranging from 15.75 GHz (laser off) to 7.02 GHz (laser on). The return-loss performance also improves with the implementation of the resonator. Without the resonator, the antenna achieves −33 dB return loss in laser-off mode and −34.15 dB in laser-on mode. With the resonator, the return loss values are −21.88 dB (laser off) and −26.61 dB (laser on). These findings indicate that the proposed configuration technique is applicable for outdoor Wi-Fi signal enhancement in the 5 GHz band and as a blind-spot sensing element for automotive radar systems.

Simulasi Gerak Pengejaran Misil terhadap Target dengan Lintasan Melingkar Menggunakan Python
type: item
description: This study aims to model the pursuit motion between guided missiles and a circularly moving aircraft using Python-based numerical simulation. The target moves along a circular path with a constant angular speed, while the missile follows a pure pursuit strategy, continuously adjusting its path toward the target's current position. Two scenarios are simulated: single pursuer and multi-agent pursuers. In the single-missile scenario, the missile forms a spiral trajectory and intercepts the target in approximately 4.9 seconds. In the multi-agent configuration, five missiles launched from different vertical positions successfully destroy the target within 8.3 seconds, with the first interception occurring at 6.7 seconds. The model is based on numerical solutions of differential equations governing relative motion dynamics. The results demonstrate that increasing the number of pursuers enhances interception speed and system effectiveness. The study is supported by animations, distance-time graphs, and damage analysis.

Designing a Restitution Experiment Using Smartphone Sound Sensor
type: item
description: This study explores the efficiency level of two experimental methods for determining the coefficient of restitution, which have been widely conducted in previous research. Using smartphones as tools in physics experiments, the coefficient of restitution can be determined through visual analysis (camera) and sound sensors to detect collisions. Phyphox is used to record time intervals and the height of the ball after impact based on the sound of the collision with the floor. Additionally, Tracker is employed for visual motion analysis of the object during the collision. The coefficient of restitution calculated using Phyphox yielded a value of 0.894 ± 0.017, while Tracker provided a value of 0.888 ± 0.014. The results indicate by reviewing the percentage error between the two methods (0.715%), Phyphox and Tracker can provide accurate data for determining the coefficient of restitution, making them effective and efficient physics experiment-based learning tools in schools.

Uji Coba Penggunaan Teepol Sebagai Bahan Alternatif pada Eksperimen Viskositas di Laboratorium Fisika Dasar
type: item
description: Viscosity experiment is one of the materials given in the Basic Physics experiment course at FPMIPA UPI which aims to measure the viscosity level of a liquid using the Stokes law method or the ball viscosimetry method. Previously, oil was often used as a test material, but its thick color made observation of the ball in the liquid difficult, especially when using software such as trackers that require visual clarity. The purpose of this study was to examine the alternative of using teepol as a test material. The research method applied is the experimental method of replacing oil with teepol. From the results of experimental data collection using Stokes' law, with 4 balls of different diameters, the viscosity value of teepol ranges from 3.36 to 4.55 kg/ms. The consistent, reliable and valid measurement results show that teepol is reliable for viscosity experiments. In conclusion, the use of teepol as an alternative material in viscosity experiments offers an innovative solution to the visual challenges faced when using oil.

Analisis Besar Medan Magnet Solenoida Menggunakan Simulasi Virtual Laboratorium Explerify
type: item
description: This study aims to analyze the magnitude of the magnetic field in a solenoid using the Explerify virtual laboratory simulation. The study was conducted with a quantitative approach by varying the number of turns (N) and electric current (I), while the coil radius (r) was kept constant at 0.015 m. The simulation results show that the magnetic field increases linearly with increasing number of turns, in accordance with Ampère's Law theory. Comparison between the simulation results and theoretical calculations shows an average difference of around 11–12%. This difference is thought to be caused by parameter limitations in the simulator, especially the length of the solenoid (L), as well as the influence of end effects that are not taken into account in ideal theoretical calculations. Thus, the results of this study indicate that the Explerify virtual laboratory can be an effective alternative for quantitative analysis.
