Abstract

Regarding the increasing use of small-field photons in clinical treatment, in this study, we investigate the use of small-field electron beams in clinical treatment. This study aimed to evaluate small-field electron beam dosimetry of the nasopharyngeal, thyroid, and ethmoid sinus carcinoma cases. Dose measurement was done using EBT3 film. In nasopharyngeal cases with a homogenous area and irregular surface, the dose discrepancies for 6 MeV energy were unpredictable except for the 5×5 cm2 field size. For all energies in 5×5 cm2 field size, the dose discrepancies were less than 3%. In these cases, we found that a smaller electron beam field will increase the percentage of the dose discrepancy. This is caused by the effect of the lateral scatter disequilibrium in a small field electron beam. For ethmoid sinus cases, dose discrepancy depends on the field size and inhomogeneity of bone and tissue organ. Based on the evaluation of doses on the spinal cord, chiasm, and larynx (OAR), it can be seen that these organs received a very small dose. From this result, a small field electron beam is recommended for cases with a homogeneous target. However, in cases with a heterogenous target, further investigation is needed.

Abstract

The aim of this study is to verify the adequacy of the surface radiation dose calculated by the Treatment Planning System (TPS) using 3DCRT and IMRT technique with the dose measured by the TLD-100, referring to the report of the American Association of Physicists in Medicine Task Group No.219 (AAPM-TG No.219). This research process began with annealing the TLD-100 at the Research Center for Safety Technology Metrology and Nuclear Quality of the National Innovation Research Agency (PRTKMMR-BRIN), followed by scanning the TLD-100 on the surface of the phantom plate using a CT simulator. In addition, the TLD-100 was calibrated with different radiation doses (0; 20; 50; 80; 100; 150; 200; 250; 370) cGy. Verification of the surface radiation dose was performed by calculating the TPS surface dose by Patient Specific Quality Assurance (PSQA) and comparing it with the dose measured by the TLD-100. The result is Radiation techniques such as IMRT are more conformal than 3D-CRT because they precisely control dose intensity, making the TLD dose in IMRT closer to TPS. Differences in detector types such as TLD also affect the results of radiation dose measurements. Continuous assessment of patient dose is important for the safety of radiation therapy.

Abstract

Penelitian ini bertujuan untuk mengetahui pemahaman kesiapsiagaan menghadapi bencana banjir pada anak usia dini, karena pemahaman kesiapsiagaan bencana bagi anak usia dini di Indonesia masih sangat rendah. Kurangnya pemberian pengetahuan kesiapsiagaan bencana khususnya bencana banjir pada anak disebabkan oleh praktik pembelajaran yang kurang efektif, karena guru belum menggunakan media pembelajaran yang beragam. Maka penelitian ini merancang produk aplikasi game edukasi berbasis komputer yaitu media pembelajaran yang menampilkan simulasi kesiapsiagaan bencana banjir. Penelitian dilakukan untuk mendesain media pembelajaran untuk pemahaman kesiapsiagaan bencana banjir pada anak usia 5-6 tahun. Metode penelitian ini menggunakan penelitian dan pengembangan dengan desain model ADDIE (Analize, Design, Development, Implementation, Evaluate). Teknik pengumpulan data berupa validasi ahli (Ahli PAUD, Media, Bahasa, dan Kesiapsiagaan Bencana) data uji coba lapangan. Penelitian dilakukan di TK Kelompok B wilayah Kabupaten Lebak. Hasil penelitian menunjukkan bahwa permainan edukasi SIGANA Banjir layak digunakan untuk memberikan pemahaman kesiapsiagaan bencana banjir pada anak. Materi pemahaman kesiapsiagaan bencana banjir pada game ini mencakup : pemahaman bahaya dan sistem peringatan dini; pemahaman mengambil tindakan untuk melindungi diri; pemahaman mengurangi dampak bencana.
ESTIMASI DOSIS 99mTc-PERTEHNETAT DARI GENERATOR 99Mo / 99mTc NON-FISI PADA ANAK-ANAK USIA 1-15 TAHUN UNTUK PROSEDUR DIAGNOSTIK Lafira, Lafira; Hidayati, Nur Rahmah; Ulya, Syarifatul; Aries, Arni; Marlina, Marlina; Ramlan, Ramlan

Abstract

99mTc-pertehnetat berguna untuk pengobatan yang disertai dengan adanya info pemberian dosis ke tubuh manusia. Penelitian ini bertujuan untuk mengetahui estimasi dosis radiofarmaka 99mTc Pertehnetat pada anak-anak usia 1-15 tahun. Metode penelitian ini dilakukan dengan berbasis uji biodistribusi mencit dengan interval waktu 0,5, 1, 3, 5, 24 jam pasca injeksi radiofarmaka. Dari data hasil uji biodistribusi diperoleh %ID/gram organ mencit, dikonversikan ke %ID/gram organ manusia. Setelah itu, hasil perhitungan diinput ke software OLINDA/EXM dengan mengamati perbedaan dosis efektif untuk anak-anak usia 1-15 tahun. Berdasarkan nilai %ID/gram organ manusia masing-masing aktivitas uptake pada interval waktu pasca injeksi dari organ tertinggi dihasilkan yaitu, otot, hati, paru-paru, dan lambung. Hasil perbandingan dosis efektif OLINDA/EXM  menggunakan t hewan dan t manusia dapat diketahui hasil yang diperoleh menghasilkan nilai dosis efektif yang lebih kecil dibandingkan setelah dikonversi ke t manusia. Rata-rata dosis serap dari organ tertinggi pada OLINDA/EXM berada di tiroid, lambung, paru-paru dan. Hasil dosis efektif yang diperoleh untuk usia 1 tahun  1.11 x 10-2, 5 tahun 6.01 x 10-3 , 10 tahun 3.96 x 10-3 dan 15 tahun 2.50 x 10-3 . Oleh sebab itu, besar dosis efektif yang dihasilkan semakin besar terhadap umur pasien yang lebih muda.

Abstract

This research was motivated by problems found at SD IT Mesjid Raya Lantai Batu which showed low student learning outcomes due to the lack of variety in the teaching materials used by teachers. This research aims to produce LKPD based on students' learning styles that are valid and practical. This type of research is development research using 4D models (define, design, development, and desseminate). However, due to limited costs and time, this development research only reached the development stage. The instruments used were validity questionnaires, teacher response questionnaires, and student response questionnaires. Based on the research results, it shows that the LKPD based on student learning styles that has been designed is very valid with an average percentage of 90.17% and the results of the practicality of the teacher response questionnaire are very practical with an average percentage of 85.08%, while the results of the student response questionnaire are very practical with an average percentage of 86.02%. So that LKPD based on students' learning styles is suitable for use in the learning process.

Abstract

Research has been carried out regarding the evaluation of scattered radiation dose during CT scans of the thorax on the gonads and thyroid using 30 patients with CT scans of the thorax. In this study, the radiation dose received by thorax CT Scan patients was measured using TLD-100 which was placed at 3 measurement points on the patient. The first point was placed on the thyroid using 1 TLD, the second point on the thorax using 2 TLDs, and the third point was placed on the gonads using 1 TLD. The thorax CT Scan examination used a tube voltage of 120 kV. The results showed that the DLP and CTDIvol values ​​affected the value of the effective dose received. The average values ​​of CTDIvol and DLP were 6.268 mGy and 782.196 mGy.cm and the average thorax dose was 2.495 mSv. The average CTDIvol and DLP values ​​obtained in the study did not exceed the threshold set by the BAPETEN Regulation in 2021, namely the CTDIvol and DLP values ​​were 16 mGy and 810 mGy.cm. Radiation that affects the gonads and thyroid organs is scattered radiation. The average radiation dose received on the gonads and thyroid organs was 0.121 mSv and 0.485 mSv. The average dose value received did not exceed the dose received on the thorax and the radiation dose received on the thyroid was greater than the radiation dose received on the gonads. This is because the thyroid organ is closer to the irradiation area than the gonad organ.
