Abstract

Dosimetric audit is crucial in ensuring and improving the quality of radiation therapy, particularly in the field of radiotherapy using techniques such as Intensity-Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT). This study employs a literature review methodology, analyzing and comparing 15 articles based on dosimeters and modalities. The results indicate that various dosimetric audit methods, including the use of glass dosimeters, Gafchromic films, ion chambers, and EPID, provide accurate results in measuring doses for IMRT and VMAT techniques using LINAC. Most studies show good success rates, with dose differences between the dosimeter and the planned dose within the tolerance limits of ±5%. However, some studies also report significant dose variations, especially in organs at risk (OAR) and areas with steep dose gradients. This study highlights that routine dosimetric audits and the use of appropriate detection technologies are essential to improving the precision and safety of radiation therapy for patients.

Abstract

This research is a quantitative descriptive research that aims to analyze the value of natural frequency and amplification factor, as well as knowing the level of resonance and vulnerability of WTT Maccini Baji Railway Bridge. This research was conducted on the Maros-Barru Railway Line, especially the WTT Maccini Baji Railway Bridge, Lau District, Maros Regency, South Sulawesi Province. Data collection was carried out at 8 points (4 points on the bridge and 4 points on the ground around the bridge) with two measurement times at each point, day and night. Processing of microtremor data using Geopsy software with the HVSR (Horizontal to Vertical Spectral Ratio) method to obtain HVSR curves that produce natural frequency and amplification values. The results showed natural frequency values ranging from 2,36 – 6,64 Hz and amplification values ranging from 2,67 – 15,92. The resonance index value of the Maccini Baji WTT Bridge obtained ranges from 30,68% – 181,49% and is included in the low resonance classification which indicates the bridge has a solid structure and is safe from potential damage due to resonance. While the seismic vulnerability index is obtained with a value of 2,07 – 77,35 which shows that the high seismic vulnerability classification is more dominant at the point located on the ground.

Abstract

Radiation dose measurement is crucial for ensuring the safety and optimization of radiology practices. Dose measurement in diagnostic radiology involves a systematic process aimed at accurately quantifying the radiation doses used during radiological procedures, ensuring compliance with safety guidelines. This study aims to evaluate and compare the performance of Optically Stimulated Luminescence (OSL) dosimeters and Thermoluminescent Dosimeters (TLD) in measuring radiation doses during diagnostic radiology procedures. The study utilized a polymethyl methacrylate (PMMA) phantom to simulate the human body. Both OSL and TLD dosimeters were employed to measure radiation doses under clinical exposure conditions. The data collected from both dosimeter types were compared to assess their accuracy, efficiency, and effectiveness in different radiological settings. The results show that OSL dosimeters offer higher sensitivity and faster reading times compared to TLDs. OSL dosimeters also demonstrate a higher level of precision, which is crucial for optimizing radiological procedures. While TLDs still provide reliable results, they require more preparation time and a longer reading process. OSL dosimeters are superior to TLDs in terms of efficiency, sensitivity, and speed, making them a preferred choice for radiation dose measurement in diagnostic radiology and contributing to safer and more accurate radiology practices.

Abstract

The process of analysing the quality of radiographic images produced by X-rays with 48 kV and 50 kV tube voltages in Covid-19 patients using ImageJ software has been carried out. The images analysed are the results of thoracic radiographic examinations using the same electric current strength in Covid-19 patients with 48 kV and 50 kV voltage variations. The image results come from converting the analogue format to digital format for further processing. The analysis method uses the FFT (Fast Fourier Transform) method and histogram analysis. Image quality was assessed based on pixel distribution, contrast and SNR (Signal to Noise Ratio) parameters. Visualisation of the distribution can be seen based on histogram analysis. In the histogram, the prominent intensity shows the pixel intensity and the peak width shows the contrast range in the image. If the histogram graph is distributed in the minimum area, the image tends to be dark and vice versa, if the histogram graph is more in the maximum area, the image tends to be bright. The results show that the 48 kV voltage has a more even distribution but has low contrast and SNR values compared to the 50 kV voltage. The results of this study provide an overview of the selection of kinetic parameters in patients and optimisation of X-ray technical parameters to obtain maximum image quality in radiographic diagnosis.

Abstract

The Modulated Arc Therapy (VMAT) technique is an advanced radiotherapy method that allows more optimal radiation dose distribution in a shorter radiation time. Several types of dosimeters that are often used for this verification include film dosimeters, OSL (Optically Stimulated Luminescence), diodes, and ion chambers, each of which has advantages and disadvantages. This review was conducted to compare the use of various dosimeters in dose verification using the VMAT technique, with a focus on the advantages and disadvantages of each tool. This research is based on a literature study of 15 articles. The literature study was carried out for 2 months. The article is limited to a discussion of environmental influences on air quality. The articles used were taken from 2015 to 2023. The results of this study show that although all types of dosimeters have advantages, selecting the right dosimeter is very dependent on the specific needs in dose verification on VMAT. Diodes, ion chambers, OSLs, and films perform well in appropriate application contexts, but each has limitations in terms of accuracy, sensitivity, and measurement time. The articles discussed show that OSL and film are more effective in dose measurements in three-dimensional distribution, while diodes and ion chambers are more appropriate for point dose measurements.

Abstract

Research on projections of greenhouse gas emissions has been carried out in the sector of transportation energy for official vehicles in Mulawarman University. The study used secondary data of fuel use of the official vehicles from 2015 until 2019 to determine the greenhouse gas emissions dominated by CO2 , CH 4 dan N2 O. The trend of the obtained greenhous gas emissions was used to predict the greenhouse gas emissions in the range of 2020 and 2030. The projections of CO 2 emissions, CH 4 emissions, and N2 O emissions, in the years, respectively, are 427,281 tons of CO2 -eq, 5,697 tons of CO2 -eq, and 5,228 tons of CO2 -eq. The calculation revealed that in the next eleven years the projection of the greenhous gas emissions due to the use of official vehicle fuel in Mulawarman University will reduce continuously.

Abstract

Heavy metal pollution is still a serious problem today. One method that can be used to remove heavy metal content from water is the adsorption method. In the adsorption method, the choice of adsorbent is very important to optimize the adsorption process. One of the materials that can be used as an adsorbent is tea waste. Tea waste contains cellulose, which can be used to bind heavy metal ions. This research was conducted to synthesize adsorbents using tea waste and then test their ability to adsorb lead ions. The adsorbent synthesis process is divided into several stages, namely washing, drying, refining, soaking in HCl solution, and drying again. The results of the adsorption tests conducted found that the tea waste adsorbent could remove 99% of the lead metal ion content in the water. The conclusion from these results is that the synthesis process has succeeded in making tea waste adsorbent that can adsorb lead ions in water.
