Abstract

Technological advances in the era of globalization cannot be separated from the basic concepts of physics, especially in the fields of electricity and magnetism. However, the reality in the field shows that many students have difficulty in understanding these concepts because learning is still theoretical and less interesting. Conventional teaching methods often make it difficult for students to connect theory with application in everyday life. Therefore, this study aims to improve students' physics literacy by utilizing science fiction film media as a more interactive and interesting learning tool. This Community Service (PkM) activity was carried out at SMA Negeri 2 Padalarang involving 63 grade XII science students. This program is designed with an approach that includes providing systematic material, discussion sessions that build conceptual understanding, and demonstrations through science fiction films that are relevant to the topic of electricity and magnetism. The use of films in learning aims to provide a more concrete visual experience so that students can more easily understand the application of physics concepts in various modern technological phenomena. This science fiction film-based approach is effective in increasing students' interest in physics, as shown through active participation in discussions and positive responses through evaluation questionnaires. This is also proven by the results of data analysis showing an increase in the average pretest score of 35.71 to 57.94 in the posttest, with an overall N-Gain value of 0.35 which is included in the moderate category. Thus, the use of science fiction film media can be an innovative alternative in learning physics that is more enjoyable and effective.

Abstract

This study investigated background radiation in Bandung City by integrating field measurements with demographic data to establish monitoring priorities. Data were collected from 60 sampling points across ten densely populated districts, covering six land-use types: open areas, residential neighborhoods, offices, healthcare facilities, industrial or waste sites, and waterways. Radiation levels were measured using a handheld Geiger–Müller counter in counts per minute (CPM) and were analyzed using medians, quartiles, interquartile ranges (IQR), and 95th percentiles (P95). Differences among districts were tested with the Kruskal–Wallis method. The citywide baseline was determined at 21 CPM, with district medians ranging from 16.5 to 23.5 CPM. Although several districts showed slightly higher or lower values, statistical results (p ≈ 0.111) indicated that the variation was not significant. Wider IQR values in some districts reflected localized heterogeneity, while Districts I and E recorded the highest P95 values. To refine monitoring priorities, a Population-Weighted Index (PWI) was applied by combining radiation levels with population data. Districts E, A, and C were identified as priority areas because of their relatively higher CPM values, larger populations, or both. Overall, the findings suggested that while background radiation levels in Bandung remained within natural ranges, incorporating demographic factors into radiation assessments provided a more effective approach for prioritizing urban monitoring, managing potential risks, and supporting public health planning.
