Abstract

Meskipun telah mengalami perkembangan yang sangat pesat, tindakan medis dengan memanfaatkan radiasi pengion, sampai saat ini masih banyak mendapatkan penolakan dari pasien dan keluarga. Hal ini disebabkan karena pengetahuan pasien dan keluarga yang minim, sehingga berakibat pada pengambilan keputusan yang keliru. Kegiatan pengabdian masyarakat ini dilakukan dengan tujuan memberikan edukasi bagi pasien dan keluarga, sehingga berdampak pada peningkatan pengetahuan yang mempengaruhi pengambilan keputusan yang benar terkait tindakan medis yang menggunakan radiasi. Media edukasi yang digunakan adalah buku saku yang disusun dengan bahasa yang sederhana dan mudah dipahami. Metode yang digunakan yaitu pendidikan masyarakat dalam bentuk penyuluhan. Responden dalam kegiatan ini adalah pasien dan keluarga yang datang ke poli pelayanan radiologi RSUP dr. Ben Mboi Kupang. Setelah dilaksanakan kegiatan ini, terjadi peningkatan pengetahuan pasien dan keluarga secara signifikan. Dengan demikian dapat disimpulkan bahwa penyuluhan dengan media buku saku efektif dalam meningkatkan pengetahuan pasien dan keluarga tentang radiasi pengion di bidang medis.

Abstract

The high-energy milling (HEM) synthesis method has produced activated carbon powder from rubber ore shell waste. The activated carbon was prepared using a chemical method with activation temperatures varying between 400, 500, and 600°C. Temperature optimization resulted in activated carbon with a maximum carbon content at 600°C. The activated carbon was then milled for various times: 0, 30, 60, and 90 minutes. The crystallinity and surface morphology of the samples were then confirmed using an X-ray diffractometer (XRD) and scanning electron microscope (SEM) characterization. Based on the XRD graph, the percentage of structural regularity, or degree of crystallinity, of the activated carbon tended to decrease from 18.17% without milling treatment to 17.52% at 30 minutes of milling, 17.45% at 60 minutes of milling, and 17.35% at 90 minutes of milling. SEM images also show a decrease in the average pore diameter from approximately 0.45 µm to 0.20 µm with a more homogeneous intraparticle morphology structure when the milling time is increased from 30 minutes to 90 minutes. This study demonstrates the potential of rubber seed shell waste for processing into activated carbon. The HEM method can significantly reduce the grain size of activated carbon and increase its surface area and reactivity, making it more effective in applications as an adsorbent and filter.

Abstract

The rapid transformation of science education in the digital era calls for pedagogical innovations that promote deep conceptual understanding rather than rote memorization. This study aims to investigate the effect of integrating PhET interactive simulations into a guided inquiry learning model on students’ conceptual understanding of elasticity and Hooke’s Law. A quasi-experimental pretest–posttest control group design was employed with 55 eleventh-grade science students at SMA Frater Don Bosco Lewoleba, Indonesia. The experimental group experienced PhET-supported guided inquiry, while the control group received guided inquiry instruction with real demonstration tools. Statistical analysis revealed that students in the experimental group achieved significantly higher posttest scores than those in the control group (t(53) = 2.89, p = 0.01), with a medium-to-high effect size (Cohen’s d = 0.67). The findings suggest that PhET interactive simulations function as cognitive scaffolds by visualizing abstract physical phenomena, reducing extraneous cognitive load, and supporting conceptual reconstruction during inquiry activities. These results highlight the pedagogical value of embedding digital simulations within inquiry-based physics instruction to enhance students’ conceptual understanding and foster meaningful learning in abstract scientific domains.
