ABSTRACTThis service activity aims to: 1) apply technology in making video-based learning media for elementary students, and 2) to add a pleasant student learning experience, 3) encouraging creative teachers to be mindful, and developing media with technology as a support to present learning in accordance with the times. The evaluation results revealed that 2 teachers (22.2%) were able to carry out/ operate the application well which is 15 step in operating Wondershare filmora and at the basic level, the teacher has been able to make multimedia simply, 3 teachers (33.3%) are good enough to complete 14 steps from 15 steps in operating Wondershare filmora application, and 4 teachers (44.5%) are still not good at operate the Wondershare filmora application only complete 5 to 8 of the 15 steps.
Several image enhancement applications can be used to increase SNR and brightness. However, if the setting of tube current-time is too high, the application can not reduce the radiation dose. So, It is necessary to test tube current-time variations on the SNR value and image quality to determine the effect on body organs and radiation dose. This study aims to determine the influence of tube current-time on SNR and with this research is expected to be an input for radiographers in the field to pay attention to parameter settings for patients. We compared five tube current-time variations on the Antebrachii examination by using Phantom (58 kV, 32 mA, 50 mSec), (58 kV, 100 mA, 50 mSec), (58 kV, 32 mA, 5 mAs), (58 kV , 32 mA, 5 mAs) and (58kV, 100 mA, 5 mAs). Then we made a circle of ROI with a diameter of 0.2 cm2 on the Bone, Soft-tissue and Air sections in that four tube current-time variations, each of which has 7 ROI points tocalculate the SNR and the radiation dose is seen from the image. There is a difference in SNR on tube current-time changes and affects the image quality with an Adjusted R square value of 0.003 and 0.865. It shows that there is a change in tube current that affects the Signal to Noise Ratio between organs. Since it is proven that changes in tube current-time affect image quality, further research can formulate an ideal parameter for the examination of each organ.
Background: Phantom radiology is used as a medium of learning as a substitute for human bones. In its use this phantom radiology has economic value high enough to be an obstacle to the learning process. Therefore, it is necessary to make a phantom with basic materials that are easily accessible and have the same density value as human bones.Methods: the method used throughout this study is through an experimental approach. The research stage involves testing the density of wood by comparing the density value of the sample used, determining the composition of the mixture between wood, contrast media and adhesives that produces phantom with the density that most closely resembles bone phantom.Results: From the results of the research, the density value of the anthropomorphic phantom humerus was 9034, and the information obtained for the density value of the four wood phantoms with basal values. Based on the results of the calculation of the density value obtained the highest value on phantom 1 with a density value of 12775, phantom with the lowest density value of 7682, namely the second phantom, the value of wood phantom density is quite close to the density value of anthropomorphic humerus phantom, namely phantom 3 with a density of 8986 and Phantom 4 density which is slightly above the wood Phantom 2 density value is 7773.Conclusions: In this study to produce wood phantom with a density that resembles bone phantom is carried out with local wood base material mixed with BaSO4 contrast media, so that the average density value is 8986 close to the density value in anthropomorphic bone phantom humerus.
Background: The use of exposure factors with high voltage / kV and low tube current / milliAmpere (mA) will provide a low radiation dose to the patient and radiographic results that provide good contrast and can reduce the onset of geometric movements. This research is to find out and study the variation of tube current/ milliAmpere (mA) on the image quality and radiation dose received by patients in the Radiology laboratory of Aisyiyah University, Yogyakarta.Methods: This type of research is an experimental study with a quantitative inferential approach, conducted at the Radiology Laboratory of the University of ‘Aisyiyah Yogyakarta. The independent variable is the tube current variation (32 and 100 mA), the dependent variable is the contras. Data collection was carried out by exposing the radiographic panthom and measuring the radiation dose with the Ray Safe X2 device. Radiograph results were analyzed by contras radiograph. Then the results will be analyzed using descriptive statistical analysis and linear regression. by testing the regression line hypothesis, the statistical test f, the statistical test t, the coefficient of determination.Results: The results showed that there was an influence of changes in tube currents (100 and 32 mA) on Soft tissue-air contrast. While the change in tube current (100 mA and 32mA) does not affect the bone-Soft tissue contrast. In order to reduce the radiation dose received by the patient, it can use a low mA value while still being able to maintain the quality of the image.Conclusions: No influence of mA change (100 and 32) on bone contrast-Soft tissue and there are influence of mA changes (100 and 32) on the contrast of Soft tissue-air.
Pancasila sebagai falsafah Indonesia harus terus dijiwai oleh seluruh warga Indonesia. Tindakan yang akan merongrong nilai pancasila harus dicegah. Pelajar Indonesia merupakan sasaran yang utama untuk menumbuhkan dan melestarikan jiwa pancasila. Penelitian ini bertujuan untuk mendeskripsikan internalisasi filsafat pancasila melalui profil pelajar pancasila. Metode penelitian ini menggunakan studi literatur atau studi kepustakaan dengan sumber referensi yang relevan. Hasil penelitian menunjukkan bahwa profil pelajar pancasila fokus pada pengembangan karakter dan kompetensi siswa untuk menghadapi tantangan global agar bisa berdaya saing tinggi. Profil pelajar pancasila terdiri dari enam dimensi yaitu : 1) beriman, bertakwa kepada Tuhan Yang Maha Esa, dan berakhlak mulia, 2) mandiri, 3) bergotong-royong, 4) berkebinekaan global, 5) bernalar kritis, dan 6) kreatif. Keenam dimensi pada profil pelajar pancasila merupakan panjang tangan dari sila-sila pancasila.
