Abstract

Telah dilakukan penelitian analisis noise level hasil citra CT-scan pada phantom dengan variasi tegangan tabung dean variasi ketebalan irisan. Penelitian ini bertujuan untuk mengetahui dan menganalisis noise level hasil citra CT-scan pada phantom kepala dengan variasi tegangan tabung dan ketebalan irisan. Evaluasi noise level harus dilakukan sehingga dapat mengurangi noise pada CT-scan dan phantom kepala air. Nilai noise level diperoleh dengan variasi tegangan tabung (80-140) kV dan ketebalan irisan (1-10) mm. Hasil noise level pada variasi tegangan tabung berkisar (0,72-2,97)%. Sedangkan noise level pada variasi ketebalan irisan berkisar (0,97-2,97)%. Hasil penelitian nilai noise level hasail CT-scan dengan variasi tegangan tabung dan ketebalan irisan maka dapat disimpulkan bahwa hasil citra ct-scan terbaik diperoleh pada tegangan tabung 120 kV dan ketebalan irisan 5 mm. kata kunci : Noise, Ct-Scan, Phantom, Data Sekunder, Tegangan Tabung, Ketebalan Irisan

Abstract

The aim of this study was to evaluate the effective of podcasts as a learning media to improve students' English listening skills in class XII of Senior High School (SMA) Negeri 2 Sorong Regency, Southwest Papua, Indonesia. The study was conducted in the academic year 2023/2024 by using a mixed method for the sequential explanatory design. Listening tests, interviews, and observations were utilized to collect data. The results were analyzed using a paired t-test and qualitative analysis. Quantitative findings indicated a significant improvement in students' listening skills, with the average score increasing from 53.31 in the pre-test to 82.53 in the post-test. It showed an average improvement of 29.22 points. The paired t-test results with a p-value of 0.000, confirmed a statistically significant difference between pre-test and post-test scores which indicate the effectiveness of podcast intervention. The correlation coefficient of 0.882 highlighted a strong positive relationship between the podcast in use and students’ improvement of listening abilities. The interview results also found that most students were interesting and helpful in using podcast for listening skills, especially since they could re-listen to better understand in spoken English. However, some students faced problems such as accents that were difficult to understand or a speaking speed that was too fast. It was recommended to use podcast as an effective media to increase learners’ listening skill achievement and their English ability.
