Abstract

Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk memberi edukasi terkait bahaya paparan radiasi dari lingkungan sekitar. Edukasi ini penting dilakukan untuk mencegah siswa mendapatkan dampak negatif radiasi elektromagnetik. Melalui pemahaman tentang bahaya radiasi, diharapkan siswa dapat membuat keputusan yang lebih bijaksana dalam menggunakan teknologi dan melindungi kesehatan. Kegiatan ini diadakan oleh Tim Dosen Prodi Fisika Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Kebangsaan Republik Indonesia (UKRI). Peserta yang mengikuti kegiatan PkM ini merupakan siswa kelas XII SMA Pasundan 1 Majalaya sebanyak 48 siswa. 35 siswa kelas XII MIPA dan 13 siswa kelas XII IPS. Kegiatan PKM dilakukan dengan penyampaian materi melalui power point (PPT) dengan metode ceramah. Untuk menguji pemahaman setelah kegiatan edukasi, siswa diberikan pre-test dan post-test. Hasil dari kegiatan ini menunjukkan adanya perbedaan tingkat pemahaman, sebanyak 2% siswa mengalami peningkatan pengetahuan yang tinggi, 38 % siswa memperoleh peningkatan pengetahuan sedang dan 60% siswa terjadi peningkatan pengetahuan yang rendah.

Abstract

To raise awareness among high school students about the risks associated with radiation exposure and gauge their level of worry, the Physics Study Program at Universitas Kebangsaan Republik Indonesia is organizing this event as a community service. 48 high school students from one of Majalaya's high schools—35 in science and 13 in social studies—participated in this activity. Five positive and five negative items were included in the Likert scale questionnaire that was utilized as the instrument. The Rasch analysis was used to find any potential biases and changes in the degree of concern for the risks of radiation exposure following socialization, and the N-gain analysis was used to find changes in that level of concern. Although the results are still low (N-gain = 0.23) and include remarks, they do indicate a shift in students' concerns over the risks of radiation exposure. First, according to the Rasch analysis, 17% of students are able to accurately respond to every statement. For the pretest and posttest, 50% and 70%, respectively, of the students can respond to every statement. Following their participation in socialization, it may be concluded that every student is aware of the risks associated with radiation exposure. Second, except from item number 10 and the suggestion that it should be revised, none of the assertions are biased against any of the groups

Abstract

This study compared the association between weighted computed tomography dose index (CTDIw) and effective milliampere-seconds (effective mAs) with the effective dose (ED) received by patients during thoracic computed tomography (CT) examinations. Retrospective data from breast cancer patients were obtained from The Cancer Imaging Archive (TCIA) and processed using IndoseCT software to extract CTDIw, effective mAs, and ED values. Descriptive statistics, scatter plots, and simple linear regression analyses were performed to evaluate the relationships between these parameters. The correlation between effective mAs and CTDIw was moderately strong (R² = 0.6774), consistent with the principle that higher tube current–time settings generally increase scanner-reported dose indices. CTDIw and ED showed a very strong correlation (R² = 0.978), reflecting the close link between standardized dose metrics and estimated patient dose. The correlation between effective mAs and ED (R² = 0.7505) was stronger than that between effective mAs and CTDIw, but still lower than the CTDIw–ED correlation. These results indicate that, in this dataset, CTDIw was a more consistent predictor of ED than effective mAs. While both parameters are relevant for dose assessment, CTDIw may be a more reliable reference for estimating ED in similar thoracic CT protocols. Although this analysis was limited to retrospective data from a specific patient group, the findings provide practical insights that can support protocol evaluation and dose optimization strategies. Further studies involving larger and more diverse datasets would be beneficial to confirm and extend these observations.

Abstract

This community service was conducted using a survey method. The survey aimed to test the understanding of high school students regarding the dangers of radiation exposure from the surrounding environment. Participants in this activity were 48 students (35 science students and 13 social science students) from a high school in Majalaya, Bandung Regency. The instrument used was a two-tier diagnostic test consisting of 4 essay questions related to physics concepts concerning radiation exposure. The analysis of the test results was divided into two parts: conception analysis and Rasch analysis. The conception analysis was done by interpreting students' answers and categorizing them into five conception categories: Full Understanding (FU), Partial Understanding (PU), Misconception (MC), Not Understanding (NU), and No Coding (NC). This categorization was presented in percentage form. The Rasch analysis was conducted based on the distribution of students' answers and item bias detection to identify the spread of students' answers to each question item and the biases present. First, the conception analysis results showed that 53% of students were included in the FU category, while only 5% were in the Not Understanding (NU) category. This indicates that students' understanding of the dangers of radiation exposure is quite good, as more than half of the participants are in the FU category. Second, the Rasch analysis results based on the distribution of students' answers showed that more students could answer basic comprehension questions compared to classification and analysis-based questions. Additionally, the Rasch analysis results based on item bias detection indicated that there was no gender or academic major bias in the four question items.

Abstract

Breast cancer is the most prevalent cancer worldwide, necessitating precise imaging techniques for effective treatment planning. This study aims to analyze the Water-Equivalent Diameter (Dw) in breast cancer patients using Computed Tomography (CT) and to investigate its relationship with patient body mass. Medical imaging data from 30 breast cancer patients, aged 23-66 years, was reviewed to calculate Dw using three different methods: contour ROI, elliptical ROI, and without ROI. The results showed average Dw values of 28.68 cm for contour ROI, 29.184 cm for elliptical ROI, and 30.255 cm without ROI. This indicates that contour ROI yields the smallest Dw due to its focus on cancerous areas. Furthermore, a positive linear correlation between Dw and body mass was established, with an R² value of 0.7743. This suggests that larger body mass leads to increased Dw values. This study emphasizes the importance of considering ROI selection and highlights the significant impact of patient body mass on Dw. This is crucial for optimizing radiation exposure in breast cancer treatment.
