Abstract

A study has been conducted on the effect of Focus Film Distance (FFD) variation on patient absorbed dose during thorax examination at the Radiology Installation of Sanjiwani Hospital, Gianyar. This study aims to determine the effect of FFD variation and the suitability of the radiation dose received by patients whether it is still within the limits of BAPETEN's decision. The X-ray machine used was Siemens Luminos Fusion Roentgen with the FFD variation method given a distance of 110 cm, 130 cm, and 150 cm in 30 patients. Dose measurements were carried out based on radiation exposure and analyzed according to BAPETEN standards. The results showed that the greater the FFD value, the smaller the absorbed dose received by patients. The highest absorbed dose obtained for FFD 110 cm was 0.3867 mGy, 130 cm was 0.2769 mGy, and 150 cm was 0.2079 mGy below the maximum limit of 0.4 mGy set by BAPETEN, so it is safe for patients. Statistical analysis of one-way t-test showed significant results, with thitung < ttabel. This indicates that FFD variation affects the absorbed dose, and all doses remain within safe limits. Thus, thorax examination at RSUD Sanjiwani Gianyar has met the established safety standards.

Abstract

Parasetamol merupakan obat analgesik-antipiretik yang banyak digunakan dalam bentuk tablet generik dengan variasi eksipien antar merek. Perbedaan ini dapat memengaruhi profil kandungan unsur penyusun tablet, seperti unsur logam kalsium (Ca) dan magnesium (Mg) yang penting untuk kontrol mutu farmasi. Penelitian ini bertujuan mengembangkan metode Laser-Induced Breakdown Spectroscopy (LIBS) untuk mendeteksi variasi unsur penyusun tablet parasetamol generik. Optimasi parameter LIBS dilakukan pada energi laser (100, 130, 150 mJ) dan delay time detection (0,1; 0,5; 1,0 µs) menggunakan sinyal unsur C, H, O, dan N sebagai acuan. Energi 150 mJ dan delay time detection 0,1 µs menghasilkan intensitas sinyal tertinggi dan dipilih sebagai kondisi optimum. Spektrum sampel standar menunjukkan puncak emisi intens untuk unsur H, N, dan O dengan unsur C terdeteksi sebagai puncak minor. Lima tablet parasetamol menunjukkan variasi profil spektral, terutama pada unsur Ca dan Mg. Tablet D memiliki intensitas puncak Ca dan Mg tertinggi, sedangkan tablet A tidak menunjukkan sinyal yang jelas pada kedua unsur tersebut. LIBS terbukti mampu mendeteksi variasi unsur antar merek tablet parasetamol secara cepat dan non-destruktif, serta berpotensi digunakan sebagai metode skrining awal dalam pengawasan mutu sediaan farmasi berbasis komposisi unsur.

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.
