Abstract

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

Abstract

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.

Abstract

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.

Abstract

This study aims to develop and validate a diagnostic instrument based on Google Forms to identify students' misconceptions on dynamic fluid material, including the concepts of discharge, continuity equations, Bernoulli's law, and Torricelli's theorem. The research was conducted using the Research and Development (R&D) method with a 4-D development model (Define, Design, Develop, and Disseminate), but was only implemented up to the Develop stage because implementation was limited. The research subjects consisted of 35 eleventh-grade students from a Madrasah Aliyah in Serang City. The research process included instrument development, expert validation, limited testing, and data analysis using the Ministep Rasch model. The results showed that the instrument had sufficient validity and reliability, with an instrument reliability of 0.91 (good category). This instrument is effective in identifying students' misconceptions, especially regarding Bernoulli's principle. This article can contribute to the development of physics learning evaluation based on diagnostic tests.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

This study aims to analyze the influence of learning resource utilization on the physics learning outcomes of Grade XI students at SMA Muhammadiyah 2 Palembang. The learning resources examined include textbooks, instructional videos, and online materials. The research instrument consists of 10 validated survey items designed to represent key indicators of learning resource use, such as frequency of utilization, diversity of sources, and relevance of materials. The survey was administered to 73 randomly selected respondents via Google Forms. Data were analyzed using simple linear regression. The results show a significance value of 0.000013 (< 0.05) and an F-value of 22.010, which exceeds the F-table value of 3.94, indicating a significant influence of learning resource utilization on students’ physics learning outcomes. Thus, the more optimally learning resources are utilized, the higher the students’ achievement in physics.
