Abstract

ABSTRAKBelajar Fisika bagi beberapa siswa dirasa sulit dan membosankan. Sehingga banyak dari siswa cendrung menghindari Pelajaran fisika. Pelaksanaan pembelajaran yang monoton tanpa praktikum kurang mengembangkan proses berfikir siswa. Padahal kemampuan berfikir siswa dalam membangun konsep Fisika juga bisa dikembangkan melalui kegiatan praktikum. Kegiatan praktikum dapat mengasah rasa ingin tahu siswa dan keterlibatan siswa menjadi lebih besar. Atas dasar itulah kegiatan pengabdian dilakukan dengan tema edukasi Fisika dan praktik roket air di MTSN 6 Sijunjung Sumatera Barat. Siswa diminta terlibat langsung dalam proses kegiatan pembelajaran. Prinsip dasar roket merupakan implemantasi dari perubahan momentum serta Hukum III Newton mengenai aksi-reaksi. Pelaksanaan kegiatan ini dilakukan dengan 3 langkah, yaitu: 1. Ceramah singkat, 2. Demonstrasi langsung, dan 3. Diskusi dan tanya jawab. Dari hasil yang di dapatkan, siswa-siswi lebih antusias belajar fisika karena mereka terlibat langsung didalam praktikum. Diharapkan kedepannya pembelajaran sains juga bisa menggunakan praktikum sebagai salah satu metode untuk meningkatkan minat siswa. Kata kunci: fisika; hukum newton; roket air. ABSTRACTLearning Physics if it is only carried out in class without practical work does not develop students' thinking processes. In fact, students' thinking abilities in building Physics concepts can also be developed through practical activities. Practical activities can hone students' curiosity and increase student involvement. On this basis, service activities were carried out with the theme of Physics education and water rocket practice at MTs N 6 Sijunjung. The basic principle of a rocket is the implementation of changes in momentum and Newton's Third Law regarding action-reaction. From the results obtained, students were more enthusiastic about studying physics because they were directly involved in the practicum. It is hoped that in the future science learning can also use practicums as a method to increase student interest. Keywords: physics; newton's laws; water rocket.

Abstract

Penelitian ini dilakukan untuk mengetahui peran penggunaan Yodium-131 dalam pengobatan kanker tiroid. Penelitian ini merupakan tinjauan literatur pada 10 artikel penelitian yang telah dipublikasikan dalam 10 tahun terakhir. Sumber informasi yang digunakan di ambil pada data publikasi Science Direct, Elsevier, Google Scholar, dan PubMed. Hasil dari beberapa penelitian menunjukkan bahwa radioaktif yodium (RAI) sangat berperan penting dalam pengobatan di bidang kedokteran nuklir terhadap pasien yang didiagnosis dengan tipe tiroid terdiferensiasi (DTC), papillary thyroid carcinoma (PTC), oncocytic carcinoma (OCA), dan follicular thyroid carcinoma (FTC). Dalam pengobatan RAI, diperlukan perhatian terhadap faktor risiko yang meliputi besar dosis yang diterima, fungsi kelenjar tiroid yang tersisa, dan aktivitas kumulatif yang diberikan sepanjang hidup pasien. Penerapan RAI yang benar dan tepat akan membantu pasien dalam pengobatan berbasis kedokteran nuklir, meningkatkan tingkat kelangsungan hidup pasien, serta meminimalkan risiko efek samping. Dengan demikian, pemahaman yang lebih baik tentang penerapan dan regulasi dosis RAI sangat penting untuk meningkatkan hasil pengobatan kanker tiroid.

Abstract

Diagnostic radiology is the most significant contributor to irradiation in the general population. Unnecessary irradiation of workers, patients, and the public during radiological procedures should be significantly reduced without affecting the medical diagnostic value. This study was conducted to analyze and evaluate the radiation dose rate, radiation protection facilities and radiation worker dose of Radiology Installation of Pariaman Regional Hospital. The method of determining the radiation dose rate at the Radiology Instalansi of Pariaman Hospital uses a PDR 303 gamma surveymeter and the rooms to be measured are CT-Scan rooms, conventional X-rays and mammography. Collecting data on radiation protection facilities, then it will be analyzed based on Nuclear Energy Regulatory Agency Regulation No. 4 of 2020 and radiation worker dose data in 2023 will be analyzed based on Nuclear Energy Regulatory Agency Regulation No. 4 of 2013. The results of the study showed that the radiation dose rate around the CT-Scan room was found to be (0.24-1.61) μSv/hour, the conventional X-ray room with irradiation using the minimum exposure factor obtained a radiation dose rate around the room ranging from (0.013-0.33) μSv/hour and with the maximum exposure factor obtained a dose rate around the room of (0.33-1.08) μSv/hour and the mammography room obtained a radiation dose rate of (0.03-0.40) μSv/hour. The radiology room facilities used by Pariaman Hospital are in accordance with the standards set by Nuclear Energy Regulatory Agency Regulation No. 4 of 2020. And the dose rate received by radiation workers at Pariaman Hospital is below the Dose Limit Value set by Nuclear Energy Regulatory Agency Regulation No. 4 of 2013. Based on the results of this study, it is found that there are several measurement points in the CT-Scan and conventional X-ray rooms that exceed the community dose limit value.

Abstract

Research has been carried out to determine the activity concentrations of radionuclides Ra-226 (Radium-226), Th-232 (Thorium-232), and K-40 (Potassium-40) in the Bukik Batabuah area, West Sumatra. The main objective of this research was to compare radionuclide levels in soils affected by cold lava floods with those exposed only to volcanic ash, and to assess whether the cold lava flow contributed to increased radionuclide concentrations. Measurements were performed using an HPGe (High Purity Germanium) gamma spectrometer. Soil samples were collected from six locations impacted by the cold lava flow and from three locations affected by ash from the Mount Marapi eruption. The results indicated that Ra-226, Th-232, and K-40 were detected in all samples. The average activity concentrations in soil affected by the cold lava flow were 14.92 ± 0.62 Bq/kg for Ra-226, 18.37 ± 0.83 Bq/kg for Th-232, and 342.15 ± 7.85 Bq/kg for K-40. In contrast, soils not affected by the cold lava flow showed average values of 10.99 ± 0.62 Bq/kg for Ra-226, 22.34 ± 1.03 Bq/kg for Th232, and 191.68 ± 5.06 Bq/kg for K-40. A t-test statistical analysis indicated significant differences between the two groups of samples. Based on PERKA BAPETEN No. 9 of 2009, the measured activity concentrations in soils around the foothills of Mount Marapi remain below the regulatory limits established by BAPETEN.

Abstract

18F-fluorodeoxyglucose Positron Emission Tomography (PET) using ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) is widely used in nuclear medicine. Accurate estimation of organ absorbed dose is important for patient safety and protocol optimization. However, standard dosimetry methods based on reference computational phantoms may not fully represent individual anatomical variability, particularly organ mass differences that influence absorbed dose estimation.This study aimed to analyze the sensitivity of absorbed dose to abdominal organ mass variations for ¹⁸F-FDG. A computational dosimetry simulation study was performed using MIRDcalc and the ICRP 133 adult male reference phantom to evaluate simultaneous mass variations of six abdominal organs within a ±50% range. A quadratic relationship was found between mass change and average absorbed dose (R²=0.9928). Dose decreased by 8.5% at +20% mass and increased by 9.2% at −20% mass. The small intestine showed the highest sensitivity (S=−0.45). Organ mass variation substantially influences absorbed dose estimates in simulation-based ^18F-FDG dosimetry. Further studies incorporating patient imaging data are required for clinical validation.
