Abstract

A study was conducted on the determination of Computed Tomography Dose Index (CTDIvol) and Dose Length Product (DLP) values of head CT-Scan aircraft in cases of Non Hemorrhagic Stroke (SNH). The study was conducted at the Radiology Installation of Prof.Dr. I.G.N.G. Ngoerah Denpasar Hospital using secondary data from head CT-Scan examination results consisting of age, gender, kV, mAs, slice thickness, rotation time, CTDIvol and DLP in patients aged 40-80 years. This study aims to determine the local DRL value at Prof.Dr. I.G.N.G. Ngoerah Denpasar Hospital does not exceed the national DRL value. It was found that in female patients the CTDIvol value in male patients was 54.9 mGy and in female patients it was 53.11 mGy. While the DLP value of male patients was 1143 mGy.cm and in female patients it was 1118 mGy.cm. Based on the results of the analysis with a one-way t-test, it can be seen that the DRL values of CTDIvol and DLP in both male and female patients do not exceed the standards set by BAPETEN No.1211/K/V/2021, so it can be said that the CT-Scan at the Radiology Installation of Prof.Dr. I.G.N.G. Ngoerah Denpasar Hospital is still suitable for use in examinations, especially head examinations.

Abstract

A study entitled Distribution of Radiation Doses Received by Organs at Risk in Cervical Cancer Using Intracavitary Brachytherapy Technique has been conducted. The study was conducted at the Radiotherapy Sub-Installation of Prof. Dr. I.G.N.G Ngoerah Hospital with the aim of determining the distribution of doses received by High Risk Clinical Target Volume (D2cc) and Organs at Risk (D90). Determining the distribution of doses received by High Risk Clinical Target Volume (D2cc) and Organs at Risk (D90) in cervical cancer patients is still within the recommended limits in ICRU Report 89. This study used ionizing radiation by inserting radioactive cobalt-60 using internal radiotherapy techniques, namely intracavitary brachytherapy. Before the irradiation process is carried out, there is a planning stage or Treatment Planning System (TPS). The reference for this research standard is for HRCTV of 95% -107% and for OAR bladder ≤80% rectum ≤75%. The average percentage of dose distribution received by HRCTV was 104.2% which is equivalent to 7.2 Gy which is still within the range of 95%- 107%, in the bladder it was 69.4% which is equivalent to 5.Gy which is still below the value ≤80%, and in the rectum it was 57% which is equivalent to 4.1 Gy which is still below the value ≤75%. The dose distribution value in HRCTV and OAR was still within the tolerance limit listed in the recommended value in GEC-ESTRO-ABS, and ICRU Report 89.

Abstract

Determination of the effective dose on the abdo pelvis and organs at risk has been carried out from the results of the CT Scan irradiation at Sanglah General Hospital.The study began by collecting secondary data from the results of an abdominal CT scan, namely the CTDIvol and DLP values. Then the data was grouped based on gender of 40 patients with an age range of 20-70 years. The value of the effective dose in the abdo pelvis is obtained by multiplying the DLP value and the conversion coefficient k. While the effective dose to organs at risk is obtained from the product of the CTDIvol and wt. The results of the effective dose in the abdo pelvis were obtained in the range of 4.596-6.738 mSv for male patients while for female patients it was 4.209-5.232 mSv. The results of the effective dose in the abdo pelvis are still at the threshold set by BAPETEN, which is 13.275 mSv, so the CT scan is still suitable for use. Average effective dose values for critical organs were 0.2882 mSv for the liver, 0.8646 mSv for the kidney, and 0.5764 mSv for the gonad. The highest dose was received by the gonads. This shows that the gonads are the organs that have the highest sensitivity in receiving radiation doses in the abdo pelvis

Abstract

Identification of groundwater using the geoelectric method in the housing area of the Udayana University boarding house, Bukit Jimbaran, Bali. Data acquisition was carried out using the Wenner configuration to determine the location of the aquifer depth with rock resistivity values. This measurement parameter is the resistivity value of the rock which is then processed using the Res2dinv software for data mapping. After that, aquifer interpretation and geoelectric data interpretation is carried out. The results showed that the aquifer in the residential area of the Bukit Jimbaran Bali Udayana University boarding house is located at a relatively shallow depth of 1.25-12.4 meters below the ground surface. On tracks 1 and 2 have 3 groups of resistivity values. The resistivity value of 2.16–37.5 Ωm with a depth of 1.25-12.4 meters is suspected as a type of tufa lithology. The resistivity value of 72.8–226 Ωm with a depth of 1.25-12.4 meters is suspected to be limestone associated with tuff. The resistivity value of 423–1363 Ωm with a depth of 1.25-12.4 meters is suspected to be limestone.

Abstract

Research has been carried out regarding the position test of the drilled well against the aquifer at the Jimbaran Unud Campus on May 12, 2023. The borehole test was carried out using the Audio Magnetotelluric (ADMT) method. To ensure that the water needs of all students at Udayana are met, it is necessary to conduct research on drilled wells at Udayana whether they are suitable for aquifer positions (groundwater). The purpose of this study was to determine the suitability of the position of the drilled well to the aquifer in the ground behind the UNUD Rectorate Building. Based on the interpretation of the results of the research conducted in this paper, the aquifer position sought on line 1 is at a distance of 0–9 m and 21–50 m at a depth of 100–200 m below the ground surface, while on line 2 it is at a distance of 7–50 m at a depth of 100–140 m. Because the position of the Udayana drilled well is at 22.2 m on line 1 and 26.7 m on line 2 with a depth of 74 m, the Udayana drilled well is not yet in the aquifer position sought in this study.

Abstract

A method that does not require a main earthquake (master event) that can be used simultaneously to relocate a very large number of earthquakes with wide hypocenter separation is called the double-difference method. A method used to relocate the aftershocks in Seririt Singaraja on November 14 2019 with coordinate positions 113.478 – 115.181 East Longitude and 8.357 – 7.894 South Latitude. The earthquake data used in this research was accumulated from 85 BMKG seismic stations. Data analysis uses cross-correlation time differences which can increase the accuracy of travel time between the receiving station and the earthquake, thereby reducing errors in calculations. The double difference method used to relocate the earthquake in the Seririt Singaraja area showed that there was a shift in the location of the earthquake hypocenter before and after it was relocated. Horizontally and vertically, the distribution of earthquake hypocenters before and after being relocated occurs when there is a collection of location shifts. The results of this research were able to relocate 152 aftershocks properly. The main earthquake after being relocated was at a depth of 17 km, while the distribution of aftershocks was at a depth of around 6-25 km, so that it can more accurately describe the position of the earthquake source and is able to show clearer and easier to interpret structural patterns.
