Abstract

A study has been conducted to determine the Diagnostic Reference Level (DRL) in non-contrast and contrast chest CT scan examinations at Bali Mandara Hospital. The study was conducted at the Radiology Installation of Bali Mandara Hospital using dose reports from non-contrast and contrast chest CT Scan examinations with data obtained including age, gender, kV, mAs, slice thick, time rotation, Pitch, as patient information and protocols used in the examination and dose information in the form of CTDIvol and DLP. This study aims to determine the local DRL value against the national DRL value. The method used to determine the DRL value in this study is by collecting data in the form of recording and documenting the dose report of CT Scan examination patients, with the data for each examination being as many as 30. From the recorded data, the CTDIvol and DLP values are used to find the DRL value by sorting it from the smallest to the largest value and then calculating the 3rd quartile as a determinant of the local DRL. The interpolation method is also used to consider the position of the 3rd quartile so that it is at a decimal value. From the research results, the CTDIvol value for non-contrast thorax examination was 6.43 mGy, and the DLP value was 293.08 mGy.cm. Meanwhile, in contrast to the thorax examination, the CTDIvol value was 6.14 mGy, and the DLP value was 852.57 mGy.cm. Furthermore, a statistical analysis was carried out in the form of a one-way t-test using SPSS software, which was used to compare the DRL values of both CTDIvol and DLP non-contrast and contrast thorax examinations with the standard values set by BAPETEN 2021 as a reference used in Indonesia. Based on the results of the analysis with a one-way t-test, it can be seen that the DRL values for non-contrast thorax examinations (DRL CTDIvol and DLP) and contrast examinations (DRL CTDIvol) do not exceed the standards set by BAPETEN. However, in the contrast thorax CT Scan examination, the DRL DLP value exceeded the standard value set by BAPETEN, so dose optimization was needed by re-evaluating the protocol implemented at Bali Mandara Hospital.

Abstract

A very important first step in helping people with mental health disorders get medical care is detection. Mental health problems and drug abuse can be detected with a tool called SDQ (for adolescents aged 10 to 17 years). The twenty-five statements in the SDQ fall into five measurable behavioral categories: (1) emotional symptoms (5 statements), (2) behavioral problems (5 statements), (3) hyperactivity (5 statements), (4) friendship problems (5 statements), and (5) prosocial behavior (5 statements). By using SDQ, this research will create an expert system, a computer-based application, to detect adolescent mental health. Expert systems can be used to solve problems in ways thought by experts. This research will build a web-based expert system that uses the PHP programming language. System and accuracy testing will be carried out using black box testing and accuracy value testing to find out whether the symptoms and diagnosis results are appropriate. The research results in the form of a prototype will be available online so that teenagers can check their mental health freely.

Abstract

Bali Island is located in an active tectonic zone due to the meeting of the Indo-Australian and Eurasian Plates, thus experiencing significant seismic activity. This study aims to analyze the seismicity characteristics, distribution, and magnitude of peak ground acceleration (PGA), and evaluate earthquake risk in Bali Island. Earthquake data for the period 1980–2023 were analyzed based on spatial and temporal distributions and the Gutenberg-Richter equation to assess the relationship between earthquake frequency and magnitude. The analysis results show that Bali's seismicity is dominated by shallow earthquakes (<60 km) with moderate magnitudes (4.5 ≤ M < 6.0) to large magnitudes (M ≥ 6.0). The highest earthquake density is in the Central and Eastern regions of Bali with an earthquake density reaching 0.02 events/km². PGA values ​​range from low to exceed 0.4 g, especially in the Central and Southeast regions associated with active faults and the Southern subduction zone. These findings provide an important basis for spatial planning, earthquake-resistant building structure design, and earthquake risk mitigation strategies on the island of Bali.

Abstract

Research has been carried out on radiation dose rate analysis in the CT-SCAN area of the radiology room at RSU Mandara Bali. The data used in this research is quantitative data observed from the radiation rate from the CT-SCAN aircraft. This study aims to determine the radiation dose rate in the radiology area and its rationalization based on regulations regarding radiation NBD (dose limit values) that apply to occupational safety and health. The research data is the actual radiation dose rate determined from the dose rate and calibration factors. The results of data calculations show that the highest dose rates are respectively at T2, 30 cm, 50 cm and 100 cm (door) with values of 1.95, 0.94 and 0.05 μSv/year, while the lowest dose rates are respectively at T4, 30 cm, 50 cm and 100 cm (waiting room) with values of 0.08, 0.06 and 0.05 μSv/year. The research results show that the dose rate at each measurement point is still considered safe for radiation workers where the NBD received is still below 20 μSv/year, while the dose rate is classified as safe for the general public at measuring distances of 50 cm and 100 cm, where the NBD received is below 1 μSv/year assuming the community concerned acts as a patient or patient's family with an interest in the radiology room area.

Abstract

The results of research that have been carried out, especially in the field of medical physics such as X-rays, have been widely utilized in the medical field, especially Radiology Units in Several General and Regional Hospitals. Thus, it is very important to be understood and known by the community, especially the community, in this case the students of SMA Negeri 2 Kuta. In 2022/2023, there are 507 male and 597 female students. Seeing these conditions, surveys and observations were carried out as a result, students had difficulty understanding physics because the physics subject matter was dense, memorized and mathematical. Seeing these results, it is necessary to carry out a new paradigm in physics learning. One of the more appropriate methods is to balance theory learning with field applications such as natural and artificial radiation measurements and applications in the field of medical physics. The results of natural radiation measurements in the classroom and outside the classroom were 0.605 ± 0.0024 and 0.182 ± 0.0008 mSv/year, respectively. The limit of the dosage rate allowed by BAPETEN is 1,000 mSv/year. Natural radiation identified in the classroom and outside the classroom is still declared safe

Abstract

This study aims to evaluate the impact of radiation exposure on the health of radiation workers at RSUD Sanjiwani Gianyar over the past five years. The evaluation was conducted through a physical approach, measuring radiation doses using Thermoluminescent Dosimeter (TLD), and a biological approach by analyzing the total leukocyte count and its components, namely neutrophils, lymphocytes, monocytes, and eosinophils. The results showed that the highest radiation dose was received by radiology specialists at 0.921 mSv, followed by medical physicists at 0.905 mSv, and radiographers at 0.894 mSv. This variation reflects differences in radiation exposure levels based on each profession's tasks and positions. Leukocyte and component analysis indicated that all values were within normal ranges. Although statistical tests showed significant differences in neutrophil levels between professions, overall radiation doses and leukocyte levels were within the safe limits set by PERKA BAPETEN No. 4 of 2013. The findings underline that radiation protection measures at RSUD Sanjiwani have been effective in minimizing health risks from radiation exposure. However, regular dose monitoring and health evaluations are necessary to ensure long-term protection for radiation workers.

Abstract

Telah dilakukan penelitian mengenai analisis dosis serap pada pemeriksaan thorax pasien anak dengan pesawat sinar-X di Instalasi Radiologi RSUD Sanjiwani Gianyar. Penelitian ini bertujuan untuk menganalisis dosis serap yang diterima oleh pasien anak pada pemeriksaan thorax serta membandingkannya dengan batas dosis yang direkomendasikan oleh United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). Penelitian ini dilakukan dengan metode kuantitatif menggunakan data sekunder dari hasil pemeriksaan thorax pasien anak berusia 1-15 tahun yang meliputi faktor eksposi (tegangan tabung, kuat arus, dan waktu eksposi). Data ini yang kemudian digunakan untuk menghitung dosis paparan dan dosis serap. Analisis statistik dilakukan dengan uji Kruskall-Wallis untuk menentukan signifikansi perbedaan dosis serap di RSUD Sanjiwani Gianyar dengan dosis serap yang ditetapkan oleh UNSCEAR. Hasil penelitian menunjukkan bahwa terdapat variasi dosis serap berdasarkan kelompok usia, di mana semakin tinggi usia pasien, semakin besar dosis serap yang diterima. Didapatkan dosis serap untuk kelompok usia 1-4 tahun yaitu:  mGy untuk pasien laki-laki dan  mGy untuk pasien perempuan. Untuk kelompok usia 5-9 tahun didapatkan sebesar mGy untuk pasien laki-laki dan  mGy untuk pasien perempuan. Sedangkan dosis serap kelompok usia 10-15 didapatkan sebesar  mGy untuk pasien laki-laki dan  mGy untuk pasien perempuan. Dosis serap yang diperoleh di RSUD Sanjiwani masih berada di bawah batas dosis maksimum yang ditetapkan oleh UNSCEAR yaitu: untuk kelompok usia 1-4 tahun sebesar 0,0300 mGy, kelompok usia 5-9 tahun sebesar 0,0400 mGy, dan kelompok usia 10-15 sebesar 0,0500 mGy.
