Abstract

Penggunaan sinar-X dalam radiologi membantu diagnosis, namun berisiko jika tidak dikendalikan dengan baik. Kolimator berfungsi membatasi area radiasi melalui celah (shutter). Ketidakteraturan frekuensi pengujian celah (shutter) dapat menyebabkan kebocoran radiasi. Pesawat sinar-X mobile di Instalasi Radiologi RSIA Zainab Pekanbaru belum dilakukan pengujian celah kolimator secara berkala sesuai standar. Penelitian ini bertujuan mengevaluasi celah kolimator pada pesawat sinar-X mobile di Instalasi Radiologi RSIA Zainab Pekanbaru. Penelitian ini menggunakan metode kuantitatif deskriptif dengan pendekatan observasional. Pengujian dilakukan melalui tiga kali eksposi dengan pengaturan shutter berbeda, menggunakan kaset dan sistem Computed Radiography (CR). Hasil citra dianalisis menggunakan perangkat lunak untuk mengukur densitas dan dibandingkan dengan standar KEMENKES RI No. 1250 Tahun 2009. Hasil pengujian celah shutter menunjukkan adanya peningkatan densitas pada area yang seharusnya tidak terkena paparan, dengan nilai melebihi batas densitas kaset tanpa radiasi. Rata-rata nilai pada tiga kali pengujian mengindikasikan adanya kebocoran radiasi pada celah (shutter) kolimator, baik di sisi transversal maupun longitudinal. Berdasarkan standar KEMENKES RI No. 1250 Tahun 2009, kolimator dinyatakan belum efisien karena masih terdapat indikasi penghitaman akibat paparan radiasi.

Abstract

Mastery of English language competence is a demand for non-English study program students. The purpose of this study is to determine the problems of learning English as ESP (English for specific purpose) in the development of teaching materials for students. This research methodology uses qualitative through systematic literature review. The results of this study are problematic in English learning of ESP are the Lecturers  face difficulties in developing ESP materials that are in accordance with student needs and the obstacle  of obtaining ESP textbooks which relevant to work field of students. Solutions to overcome the problem of learning special English (ESP) in students in the Digital Revolution era involve industry-relevant curricula, the use of digital technology, interactive and contextual content, collaboration with industry,  Soft skills development, Project-based learning, comprehensive evaluation, a student-centered approach, and psychological and technical support for students who need it.
