Abstract

The use of Mobile Digital Radiography (Mobile DR) in radiology services continues to rise due to its flexibility and efficiency; consequently, the implementation of Quality Control (QC) and regular evaluation of radiation protection equipment are necessary to ensure service quality and radiation safety. This study aims to evaluate the implementation of QC on Mobile DR equipment and to assess the suitability of lead aprons using CT scans at the Radiology Department of the NTB Provincial General Hospital. This is a quantitative descriptive study with the research subjects comprising one unit of mobile DR and 13 lead aprons. QC testing was conducted on the parameters of illumination, collimation, and X-ray beam alignment, while the apron suitability test was performed using a 64-slice CT scan to detect lead material leakage. The results showed that the illumination value was 198 lux, collimation was within tolerance limits, and beam alignment was 0°, meaning the Mobile DR unit was deemed to meet suitability standards. Furthermore, 5 out of 13 lead aprons (38.46%) exhibited leakage exceeding tolerance limits and were deemed unfit for use. These findings underscore the importance of implementing quality control (QC) and regular inspections of radiation protection equipment as part of the Quality Assurance programme to ensure the quality of radiology services and radiation safety at the NTB Provincial General Hospital.

Abstract

The rapid development of science and technology requires science learning to focus not only on conceptual understanding but also on the development of science process skills, critical thinking, and technological literacy. One approach to addressing this challenge is the use of science learning teaching aids based on kits and sensors. This study aims to systematically review the variations of science teaching aids developed and implemented in previous studies, focusing on the types of kits and sensors, science domains, and their impact on students’ learning outcomes. This research employed a literature review method using a systematic literature review approach. Relevant articles were identified through Google Scholar and ResearchGate databases. A total of 25 selected articles were analyzed descriptively based on tool characteristics, applied technologies, and key research findings. The results indicate that kit- and sensor-based teaching aids, particularly those integrating microcontrollers and digital sensors, significantly enhance students’ conceptual understanding, science process skills, and higher-order thinking skills. Furthermore, these teaching aids effectively support experiment-based, inquiry-oriented, and STEM learning approaches. Therefore, science learning teaching aids based on kits and sensors demonstrate strong potential as innovative and contextual tools to improve the quality of science education.
