Enhancing Critical Thinking and Spiritual Attitudes through Qur’an-Integrated Solar System Learning in Pesantren-Based Madrasah Aliyah: A Quasi-Experimental Study
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.

Analysis Absorbed Dose Sensitivity of 18F-FDG to Abdominal Organ Mass Variation Using MIRDcalc
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.

A Needs Analysis for Developing a STEM-R Module on Renewable Energy to Foster MTs Students' Creative Thinking
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
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.

Korelasi SST, OLR Terhadap Curah Hujan di Wilayah Pesisir Timur Sumatera
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.

Rekonfigurasi Antena Folded Dipole Mikrostrip Berbasis Laser Merah dan Microwave Multifunctional Analyzer (MMA)
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
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.

Pembuatan Sensor SnO₂ untuk Memantau Multi-Parameter dalam Proses Pembusukan Makanan
This study reports the development of a tin dioxide (SnO₂)-based gas sensor fabricated via the electroplating method for monitoring food spoilage. Urap vegetables were used as test samples to investigate variations in temperature, CO₂ concentration, humidity, and sensor resistance during the spoilage process. The results revealed that the SnO₂ sensor exhibited a clear response to temperature and CO₂ concentration, both of which showed a consistent decrease in resistance with increasing values. In contrast, no definitive correlation between resistance and humidity was observed. These findings highlight the potential of electroplated SnO₂ sensors as multi-parameter devices for real-time food spoilage monitoring. Such an approach could be further optimized for practical applications in smart packaging and food quality control, thereby supporting food safety and waste reduction.

Designing a Restitution Experiment Using Smartphone Sound Sensor
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.

Studi Faktor Kualitas Resonansi Bunyi pada Pipa Organa Tertutup Menggunakan Panjang Efektif
This study aims to improve the accuracy of resonance analysis in closed pipe resonance through the measurement of quality factor (Q) and effective air column length. The method employed involves an automated system based on Arduino, equipped with an HC-SR04 sensor to measure distance and a KY-037 sensor to detect sound amplitude, integrated with Python-based data analysis for determining the resonance frequency. The measurement results show that the use of effective length with tube radius correction and improved frequency determination methods can reduce error from 1.33% to 0.24%, as well as decrease the standard deviation from 0.45 cm to 0.37 cm. Furthermore, quality factor analysis indicates an increase in the average value from 20 to 31, suggesting that the implemented resonance system and analysis method provide more accurate results, despite increased variability. Overall, the system successfully delivers more precise measurements in the analysis of resonance characteristics in closed organ pipes, particularly in relation to energy dissipation.

The volume proportion of banana stem fibre was varied from 0% to 25% in order to mould each sample into a composite. A two-hour alkalisation treatment with 5% NaOH was applied to banana stem fibre. A Universal Testing Machine (UTM) was used to assess the samples' tensile strength, and an optical microscope was used to examine their microstructure. According to the study's findings, the tensile strength values of composites with volume fractions of 0%, 10%, 15%, 20%, and 25% were 5.9 Mpa, 11.9 Mpa, 8.9 Mpa, and 7.9 Mpa, respectively. It is evident that the sample with the best tensile stress value, 11.9 Mpa, has a 15% banana stem volume fraction.

Uji Coba Penggunaan Teepol Sebagai Bahan Alternatif pada Eksperimen Viskositas di Laboratorium Fisika Dasar
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
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.

Studi Eksperimen Penggunaan Simulasi PhET dan Metode Drill dalam Pembelajaran Fisika Gerak Peluru pada Mahasiswa Teknologi Hasil Pertanian
This study aims to compare the effectiveness of using PhET simulations and the drill method in physics education, specifically on the projectile motion concept, for students of the Agricultural Technology program. The study employed a quasi-experimental method with a pretest-posttest design on two groups of students. The experimental group (R001), consisting of 37 students, used PhET simulations, while the control group (R002), consisting of 40 students, used the drill method. The results showed a significant increase in learning outcomes for both groups. The average posttest score of the PhET simulation group increased from 50.41 to 87.15, while the drill group's average score increased from 49.75 to 76.05. An independent t-test showed a significant difference between the two groups' posttest results (p<0.001). This study concludes that PhET simulations are more effective in improving students' understanding of projectile motion concepts compared to the drill method. PhET simulations allow students to manipulate variables interactively, while the drill method focuses more on repetition of problem-solving

Perlindungan Sensor Suhu Cu/Ni dengan Nitroselulosa
Coating of Cu/Ni with nitrocellulose (NC) has been carried out with the aim of determining the effect of using NC as a protective film on the sensitivity and activation energy of the sensor. The samples used were Cu/Ni and Cu/Ni/Cu where the NC coating on Cu/Ni was carried out using a spray method with a pressure of 1.2 Mpa. Both sensor samples were used to measure the temperature of liquid nitrogen (liquid N2) which was varied from -160C - 0C. In addition to temperature, voltage and current were also measured. The sensitivity value was obtained from the slope of the resistance curve against temperature, while the activation energy was obtained from the slope of the logarithm of conductivity against one per absolute temperature. From the sensitivity test, it is known that both sensors have a tendency to be more sensitive when the temperature is lowered, but the presence of the NC layer causes a decrease in sensitivity of up to 18.9%, namely from 3.95 /C to 3.18 /C at a temperature of -160C following the equation S(T)=0.10e-0.012T. The use of NC protective layer can also increase the activation energy by 1.3%, namely from (4.29  0.01)x10-9 eV to (4.35  0.01)x10-9 eV. These results can be used as a consideration for temperature sensor manufacturers that the use of NC protective layer is important but can reduce sensor sensitivity.

Etnofisika Permainan Tradisional Dodorobe Sebagai Pengembangan Bahan Ajar Fisika
The purpose of this study is to produce physics teaching materials related to the Dorobe game that are suitable for use by high school students and to find out the students' response to the teaching materials developed. The research was conducted in a small group of 15 students from SMA Negeri 6 Ternate. The method used in this study is a 4D development study which includes four stages, namely definition, design, development, and dissemination through an ethnographic approach to examine the physical concepts contained in the dodorobe game. The data analysis technique in this study is the Likert scale. As a result of this study, the average percentage of physics teaching materials based on evaluation by material expert validators was 72.5%, the average percentage of assessment by media validators was 87.5%, and the students' response to the teaching materials developed based on linguistic, material and appearance aspects was very good with a score of 80.9%. For this reason, physics teaching materials in the traditional game of dodorobe are feasible in the process of learning physics on impulse and momentum materials.
