Abstract

Boron Neutron Capture Therapy (BNCT) is a relatively safer technology for killing cancer cells, one of which is the Glioblastoma multiforme. One of the main components of the BNCT equipment is the collimator which functions as an exit point for epithermal neutron particles that hit cancer cells. In addition to the experimental method, BNCT research can be carried out by modeling, including using the MCNPX software based on the Monte Carlo Method. This research aimed to determine the flux distribution of fast and epithermal neutrons and the dose rate of fast neutrons and gamma that hit the target cancer cells in the phantom head of ORNL MIRD. Modeling using the MCNPX software has three main parts: cell cards, surface cards, and data cards. A tally is used on the data card to calculate the neutron flux. Based on the calculation of the modeling results, the flux of epithermal neutron is 2.87 x 109 n/cm2.s. The dose ratio of the epithermal to the fast neutron flux is 2.29 x 10-14 Gy.cm2/n. Then, the balance of the dose rate of the epithermal to the gamma is 1.64 x 10-14 Gy.cm2/n, and the ratio of epithermal to thermal neutron flux is 0.004. In this study, the epithermal neutron flux hitting the target cancer cells in cell target was moderated at 4 cm so that at a depth of 8 cm, the energy was converted into thermal neutrons. Based on the analysis of the results, it can be concluded that the neutron flux that will interact with cancer tissue is thermal neutrons, not epithermal neutron flux.

Abstract

Computational simulations of proton therapy with a pencil beam collimator for craniopharyngioma have been done using MCNP6. A pencil beam was radiated towards cube shaped tumor cells in size 1.2 cm, located at a 5.4 cm depth from the surface of the scalp. A 0.1 cm pencil beam was radiated from the left 19.6 cm from the scalp. The cube of tumor cell is divided into the front layer, middle layer, and back layer. Each layer of the tumor cell is divided into 9 cubicles, thus there are 27 cubicles. Using various energy from 108 MeV to 115 MeV and various intensity of energy for each irradiation, it produces the dose for each cubicle in unit MeV/gram per proton. The best isodoses occurred in 5 variations of energy which is 108.2; 111.2; 113.4; 114.7 and 115 MeV. The healthy organ that received the largest dose of the proton is the brain, it is (7.38±0.01)×10-2 MeV/gram per proton, or only 0.412% compared to the tumor cell dose.

Abstract

This study investigates the impact of cooperative learning on suburban students’ motivation. This study used an experimental approach by comparing the effectiveness of cooperative learning in the experimental group with traditional learning in the control group. The research began by carefully identifying schools in a developing industrial area in Cerme, Gresik City, Indonesia. Data collection was carried out carefully through documentation techniques, including taking various documents and records directly related to student learning motivation. This research group featured 224 high school students divided into two equal groups: 146 students in the experimental group and 145 students in the contr with traditional learning. The data were analyzed using the t-test as an analytical tool to measure and establish the statistical significance of the differences between these two groups of students. The research results clearly show the positive impact of cooperative learning on student motivation, as shown by the p-value of 0.014. In light of these important findings, future research directions have been carefully outlined to include in-depth and longitudinal investigations of motivational sustainability within cooperative learning frameworks, exploration of the potential for cultural variation, refinement of teacher training methodologies, integration of modern educational technologies, and development of parental involvement initiatives and innovative. Cooperative learning can increase student motivation and enrich and stimulate academic environments.

Abstract

Thermoluminescence dosimeter (TLD) is widely used as a personal and medical dosimeter. Several TLD materials show the characteristics of mass energy absorption coefficient and energy response relative to ICRU (International Commission on Radiation Units and Measurements) issue material as an equivalent material for human body soft tissue. This research aims to analyze the effect of Dy3+ dopant on the mass-energy absorption coefficient and relative energy response of Lithium Magnesium Borate (LMB) materials. The simulation was carried out using Monte Carlo N-Particle (MCNP) software. Calculations based on simulation and theoretical results will be compared statistically using paired t-tests. The study showed that adding a Dy3+ dopant to TLD material made of Lithium Magnesium Borate (LMB) only affected the mass-energy absorption coefficient and relative energy response for low radiation energy. Adding Dy3+ dopant increased the mass energy absorption coefficient and relative energy response in a reasonably small value. Based on these results, LMBDy3+ produces a better mass-energy absorption coefficient value for TLD materials. The results of the statistical tests show a significant difference in the mass energy absorption coefficient value. At the same time, there is no significant difference between the simulation results and theoretical calculations for the relative energy response.

Abstract

Glioblastoma multiforme merupakan kanker otak stadium IV yang sangat sulit diobati dan umumnya terjadi pada hemisfer serebrum otak. Terapi BNCT telah dikembangkan untuk pengobatan glioblastoma yang lebih aman, namun hamburan neutron dan foton gamma yang berasal dari terapi pada organ at risk ini perlu dievaluasi menggunakan simulasi. Metode yang dilakukan dengan mensimulasikan phantom ORNL-MIRD bagian kepala dan leher menggunakan program MCNPX. Arah penyinaran radiasi terhadap pasien dibuat menjadi dua arah yaitu RLAT dan TOP. Perhitungan dosis dalam BNCT dilakukan dengan mencari nilai dosis serap, dosis ekuivalen, dan dosis efektif. Dosis efektif dianalisis menggunakan ICRP publikasi 60 dan 103. Berdasarkan perhitungan dosis serap, arah penyinaran yang paling efektif adalah arah penyinaran TOP, dengan persentase dosis serap pada organ at risk relatif aman terutama pada organ tiroid, dan nilai pada organ cranium, otak, tiroid, dan kulit berturut-turut sebesar 11,4%, 10,15%, 0,002%, dan 6,4%. Nilai dosis efektif pada ICRP 60 dan 103 bernilai sama pada organ cranium dan kulit. Namun, pada organ tiroid, nilai dosis efektif dengan ICRP 103 lebih rendah dibandingkan ICRP 60. Hal ini menandakan berkurangnya resiko untuk penyakit terwaris pada tiroid, dan pada organ otak hanya dihitung menggunakan ICRP 103

Abstract

Dalam proses radioterapi, distribusi dosis yang akan diterima pasien perlu diestimasi terlebih dahulu sebelum dilakukan penyinaran agar pemanfaatan terapi radiasi dapat optimal. Perhitungan dosis radiasi tersebut dapat disimulasikan dengan program MCNPX. Dalam penelitian ini, karakteristik kurva Percentage Depth Dose (PDD) dan distribusi dosis serap pada organ pankreas serta tulang belakang dihitung berdasarkan simulasi dengan MCNPX. Phantom yang digunakan adalah jenis ORNL-MIRD phantom (1996 version) yang telah dimodifikasi. Phantom nonhomogen disisip dengan organ paru-paru di kedalaman 5,0-14,0 cm, pankreas, dan tulang belakang. Luas lapangan radiasi 10×10 cm2, arah penyinaran radiasi Anterior-Posterior (AP). Penelitian dilakukan dengan variasi Source Surface Distance (SSD) sebesar 95,0 cm, 97,5 cm, 100 cm, 102,5 cm, dan 105 cm. Hasil penelitian menunjukkan bahwa karakteristik kurva PDD phantom homogen mengalami peningkatan hingga kedalaman 2,0 cm untuk seluruh SSD. Kurva PDD kemudian mengalami penurunan secara eksponensial. Kurva PDD untuk phantom nonhomogen menunjukkan perbedaan pola di daerah sebelum paru-paru, di paru-paru, dan setelah paru-paru. Selanjutnya, distribusi dosis serap terendah untuk organ pankreas dan tulang belakang didapatkan saat menggunakan SSD 105 cm. Manfaat dari temuan ini adalah dapat membantu memaksimalkan kinerja pada proses Treatment Planning System (TPS).

Abstract

Proton therapy modeling for treating craniopharyngioma tumors was conducted using a pencil beam collimator, and variations in beam directions were performed using MCNP6 software. The simulation was carried out on a head and neck phantom with the tumor cells modeled within a cubic irradiation area geometry with a 1.2 cm side length, divided into 27 small cubic voxels with a small voxel side length of 0.4 cm. The radiation source from the irradiation area's right, left, and top directions, with a diameter of 0.4 cm, was directed at each cubic voxel. Variation in radiation source directions indicated that irradiation from the right direction of the irradiation area is the most recommended approach, with a dose uniformity level of 83.47%. Healthy organs surrounding the irradiation area received lower doses than those obtained by tumor cells, and the majority remained below the Organ At Risk (OAR) threshold. Healthy organs received the highest dose, particularly in the brain region, at a relative 0.46% compared to the total dose received by tumor cells.
