Abstract

Cigarette smoke pollution contains PM₂.₅ particles with sizes ranging from 0.1 to 2.5 µm, along with nicotine and tar, while conventional filters have limited effectiveness in capturing ultrafine pollutants. The increasing use of Styrofoam in various industries has contributed to environmental challenges due to its resistance to natural degradation and limited recycling. This study develops an electrospun nanofiber-based cigarette smoke filter from recycled Styrofoam by optimizing electrospinning parameters to achieve controlled fiber morphology and enhanced filtration. Optimized parameters—including applied voltage, flow rate, needle-to-collector distance, viscosity, and solution concentration—enabled the fabrication of nanofibers with uniform morphology. SEM characterization revealed fiber diameters ranging from 0.88 to 2.23 µm, with a basic weight of 0.005–0.009 g/cm², thickness of 0.007–0.016 cm, and porosity of 61–76%. Filtration tests demonstrated PM₂.₅ capture, with visible tar deposition turning the nanofibers yellow-brown. Nanofiber mass increased post-filtration, correlating with contact time variation. Post-filtration FTIR analysis revealed peak shifts at 3377–3413 cm⁻¹ (OH stretching) and 1447 cm⁻¹ (NH bending), indicating nicotine and tar adsorption. These findings demonstrate that electrospun styrofoam-derived nanofiber membranes provide an effective alternative for cigarette smoke filtration, offering high efficiency and a sustainable approach to plastic waste reduction

Abstract

Breast cancer is the most commonly diagnosed cancer among women worldwide and remains one of the leading causes of cancer-related deaths, accounting for approximately 10 million deaths in 2020. Diagnosis is generally performed through routine examinations or when symptoms appear; however, physical examination alone is often insufficient. Image segmentation techniques are increasingly utilized to enhance diagnostic accuracy. This study aims to develop a MATLAB-based program using the Graphical User Interface (GUI) and the Active Contour Lankton method to perform segmentation on mammogram images for breast cancer detection. The process involves several stages: acquiring the original mammogram image, enhancing the image using intensity adjustment, applying the Active Contour Lankton segmentation technique, and measuring the diameter of suspected cancerous regions in 15 sample images. The results show that the program was able to identify breast cancer in several cases with good sensitivity and also demonstrated potential in reducing false-positive findings in images from patients confirmed to be cancer-free. Nevertheless, several false-positive errors were still observed, indicating that the segmentation accuracy requires further improvement. This study advances computer-aided diagnostic tools by integrating the Active Contour Lankton method into a user-friendly MATLAB GUI framework. The proposed approach offers a practical and accessible solution for supporting early breast cancer detection and minimizing diagnostic errors in clinical practice.

Abstract

Understanding environmental literacy is essential for prospective physics teachers to develop responsible behaviors in responding to environmental changes. However, assessing attitudes toward the environment remains challenging due to the limitations of existing instruments. This study evaluates the feasibility of an environmental affect instrument designed for prospective physics teachers in environmental physics courses. The research employed Thiagarajan’s 4D development model, which consists of four stages: define, design, develop, and disseminate. The instrument was validated by experts and users, with expert validation analyzed using Aiken’s V, user validity assessed through Pearson correlation, and reliability measured using Cronbach’s Alpha. Data analysis was conducted using Microsoft Excel and SPSS 16.0. The findings indicate that the developed instrument is highly valid, with an Aiken V value of 0.83 from expert validation. User validation resulted in 18 valid items and two invalid ones, while the reliability coefficient (Cronbach's Alpha) was 0.81, indicating high reliability. Consequently, 18 out of the 20 developed items are suitable for broader implementation. These findings provide a valuable tool for physics education lecturers and study programs in assessing students' environmental attitudes.

Abstract

A dosimetric analysis of a 6 MV photon energy radiation beam on flatness and symmetry in LINAC radiotherapy at UNAND Hospital has been conducted. The aim was to measure the quality of the photon beam using an ion chamber cc 13 detector by observing the beam profile and analyzing the effect of field size and irradiation depth. This study used a blue phantom as the object of irradiation with 6 MV photon energy and variations in irradiation field size.  The results showed that the PDD curve at 6 MV energy was by the international standard recommended by BJR-25. Then, the average values of flatness and symmetry in the field area of 10×10 cm2 and 15×15 cm2 are 1.6% and 2.4% for flatness and 2.3% and 1.9% for symmetry. Thus, the dose distribution is more uniform, and both the left and right sides of the profile on the center axis appear balanced, which will help deliver the dose to the patient better. Thus, these values are suitable for clinical use. This study found that the beam profile was larger on the left side of the main axis. This must be considered to ensure the dose distribution complies with the established safety standards. The results also show that variations in the field area and irradiation depth can affect the beam profile, and the resulting flatness and symmetry values are in accordance with the IAEA TRUS-381 and AAPM TG-142 recommendation standards, which are ±2% flatness and ±3% symmetry.

Abstract

This research aims to develop valid physics teaching materials based on Islamic values, assess their practicality, and analyze their effectiveness in improving scientific literacy skills. This research was conducted at MAN 2 Bulukumba with 27 eleventh-grade class A students and 9 physics teachers as practitioners. This research employed the 4D development model: define, design, develop, and disseminate. The materials' validity was evaluated using Aiken’s V, focusing on content, presentation, language, and graphics, and were deemed valid and suitable for use. Practitioners rated the materials as very practical across all assessed aspects. Effectiveness was analyzed through pre- and post-implementation tests of students’ scientific literacy, yielding an N-gain of 67% (effective criteria). The study concludes that physics teaching materials based on Islamic values are valid, practical, and effective in enhancing students' scientific literacy. Integrating Islamic values into physics learning strengthens students' understanding of scientific concepts while fostering a holistic perspective that connects science with spiritual and moral dimensions. This integration also increases students' motivation by demonstrating the relevance of physics to their religious teachings, making science learning more engaging. Furthermore, it facilitates contextual teaching of physics concepts, particularly in environments rich in Islamic values.

Abstract

Education in the 21st Century significantly emphasizes developing key competencies, including social responsibility. However, a substantial gap persists between students' theoretical understanding of social responsibility and its practical application, particularly in physics education. This study aims to develop a physics student worksheet based on the ENACT (Engage, Navigate, Anticipate, Conduct, and Take Action) learning model to foster social responsibility among students aged 15 to 16. This study employed the Research and Development (R and D) methodology and adopted the Borg and Gall development model (stages 1–7), involving validation by media and content experts and a practicality assessment. The sample comprised two teachers and 127 students from two public schools in Bandar Lampung, with data collection techniques including structured interviews, observations, and Likert-scale questionnaires. Validation results indicated high quality, with 92% from media experts and 94% from content experts, while practicality assessments yielded scores of 93% from teachers and 89% from students, categorizing the worksheet as highly practical. The teachers and students provided positive feedback, highlighting the worksheet's ease of use, relevance, engaging content, and potential to cultivate social responsibility among students. This study contributes to integrating digital technology into physics education by underscoring the role of interactive learning tools in fostering social responsibility. However, further research is recommended to examine the effectiveness of ENACT-based e-worksheets in diverse educational contexts and across different subject areas.

Abstract

Data centres are considered the exclusive sites of information technology and computer science. However, many aspects of their day-to-day operation can be used to teach important concepts in physics, such as heat transfer, AC and DC power transmission, fibre optic transmission, energy loss in transmission cables, and electronic componentry. Data processing requirements and power usage in data centres are growing exponentially, and therefore, solutions need to be developed to reduce energy costs, given the challenges of global warming. To this end, work is being done on storing data in strands of DNA. An experiment to measure the change in temperature of air passing through an internet hub is described as a means of teaching students about the physics of data centres. The procedure and calculations shown in this particular experiment can be used and applied by secondary school physics students to evaluate the energy budget and efficiency of different data centres, such as those used at their school. In addition, this article details how students can make simple calculations that directly show how novel DNA data storage technology can be utilized to reduce the amount of hardware and power used at data centres. The potential for quantum computing to reduce the power requirements of data centres is also discussed.

Abstract

This research investigates the effect of oxygen flow valve orifice size on the thermal conductivity of a small-scale industrial husk furnace's pan and chimney. The researchers used a water boiling test to the thermal conductivity at varying valve hole sizes: 3627 cm, 3634 cm, 4334 cm, and 5034 cm. The pan, crucial for direct contact with cooking ingredients, and the chimney, responsible for fire flow during combustion, play vital roles in heating. The chimney, constructed of clay and zinc, exhibited thermal conductivity values ranging from 0.52 to 0.59 W m⁻¹ °C⁻¹. The highest chimney thermal conductivity was observed at the 50x34 cm valve hole size, attributed to a smaller temperature difference between the inner and outer chimney surfaces. The pan's average thermal conductivity ranged from 2.95 to 4.10 W m⁻¹ °C⁻¹, with the highest value recorded at 5034 cm orifice. This finding suggests a direct relationship between the valve hole size, heat transfer rate, and the pan's thermal conductivity. The research reveals the influence of oxygen flow on heat transfer within the husk furnace, providing valuable insights for optimizing its design and efficiency. While the chimney's thermal conductivity remained relatively stable across different orifice sizes, the pan's conductivity showed greater variation, potentially indicating inconsistent heat distribution. Further research with more precise temperature measurement techniques is recommended to refine these findings.
