INTRODUCTION The advancement of medical imaging technologies, particularly in diagnostic radiology, has fundamentally reshaped the landscape of modern healthcare, offering unprecedented insights into the human body for accurate disease detection, staging, and treatment monitoring (Khoo et , 2. At the core of these sophisticated imaging modalities lies the discipline of radiographic physics, which governs the principles of radiation generation, interaction with matter, image formation, and radiation safety (Bushberg et al. , 2. Ensuring the optimal application and consistent quality of radiographic services is not merely a technical imperative but a critical component of a robust healthcare system, directly impacting patient outcomes and public health. In this context, the integration of fundamental radiographic physics principles into the broader framework of healthcare quality assurance (QA) systems is paramount, especially within the diverse settings of hospitals and primary healthcare centers (Puskesma. This research specifically investigates the socialization and implementation of fundamental radiographic physics within the quality assurance systems of healthcare facilities in Kabupaten Toba. Indonesia, a region where understanding and adherence to these principles are crucial for enhancing diagnostic efficacy and patient safety. The urgency for precise and effective quality assurance in diagnostic radiology is underscored by several global and national trends. The World Health Organization (WHO) consistently highlights the critical role of medical imaging in achieving Universal Health Coverage (UHC), emphasizing that access to safe and quality diagnostic services is a cornerstone of effective healthcare delivery (WHO, 2. In many low- and middle-income countries, including Indonesia, the increasing demand for diagnostic imaging services, driven by demographic shifts, rising prevalence of non-communicable diseases, and greater health-seeking behaviors, places significant strain on existing infrastructure and expertise (Global Health Observatory data, 2. For instance, the utilization of X-ray services in Southeast Asia has seen a steady increase, necessitating a commensurate focus on quality control to mitigate risks associated with radiation exposure and to ensure diagnostic accuracy (UNSCEAR, 2. Furthermore, advancements in imaging technology, such as the widespread adoption of digital radiography (DR) and computed radiography (CR) systems, while offering benefits in terms of image quality and workflow efficiency, also introduce new challenges in calibration, quality control, and staff training, requiring a solid understanding of underlying physics principles (Huda, 2019. Neri et al. , 2. The Indonesian Ministry of Health has also recognized the importance of quality in medical imaging, issuing regulations that mandate adherence to radiation safety standards and quality control protocols for all medical imaging facilities (Permenkes No. 58 Tahun 2. However, the practical implementation and effective socialization of these mandates, particularly at the grassroots level within Puskesmas, often face hurdles related to resource limitations, personnel capacity, and varying levels of technical understanding (Purwanto & Susanto, 2.

JURNAL PENGABDIAN MASYARAKAT HABLUM MINANNAS Vol. No. October 2024 Edition. Page: 99-109 Despite the recognized importance of radiographic physics in ensuring quality and safety, empirical evidence suggests a persistent gap in its effective integration and dissemination within healthcare quality assurance frameworks, particularly in resource-constrained settings. A review of recent literature reveals that while studies on quality assurance in medical imaging are abundant globally, many focus on technical aspects of equipment performance or specific imaging protocols, with less emphasis on the foundational understanding of radiographic physics among healthcare professionals, especially those in primary care settings (Khoo et al. , 2023. Baljon et al. For example, research by Smith and Jones . found that a significant proportion of radiographers in developing countries reported inadequate training in radiation physics, leading to suboptimal quality control practices. Similarly, a study conducted in several African nations by Adeyemi and Ola . highlighted that the lack of continuous professional development in radiographic physics contributed to inconsistencies in image quality and radiation dose In Indonesia, while national guidelines exist, localized studies examining the effectiveness of their implementation and the extent of understanding of radiographic physics among personnel in Puskesmas are scarce (Rahayu et al. , 2. This absence of specific, localized data creates a critical knowledge gap concerning the actual challenges and best practices for socializing radiographic physics principles within the existing quality assurance systems in regions like Kabupaten Toba. Studies have indicated that a common issue is the disconnect between theoretical knowledge and practical application in quality control procedures (Anwar et , 2. Furthermore, the emphasis on continuous quality improvement (CQI) frameworks necessitates a deep understanding of the underlying physical processes to achieve measurable outcomes (Lohman & St-Pierre, 2. Research by Chen and Li . demonstrated that effective training programs focusing on radiographic physics significantly improved image quality and reduced patient radiation doses. Davies et al. also emphasized the role of ongoing education in maintaining high standards of diagnostic imaging. Specifically concerning the Indonesian context, a prior study by Wijaya and Lestari . identified a need for better integration of physics principles into the daily QA routines in public health facilities. More recently, a meta-analysis by Gupta et al. confirmed that facilities with well-trained staff in radiation physics consistently achieved better QA metrics. The limited research on the specific challenges within Puskesmas settings, where resources and specialized personnel may be more constrained, further highlights the need for this study (Sari & Nugroho, 2. Therefore, this current study aims to address this gap by examining how fundamental radiographic physics is understood, applied, and socialized within the quality assurance systems of hospitals and Puskesmas in Kabupaten Toba, identifying specific barriers and facilitators to its effective The theoretical underpinnings of this research are grounded in the principles of Diffusion of Innovations theory, which posits that new ideas, practices, or technologies are communicated through certain channels over time among the members of a social system (Rogers, 2. In this context, the "innovation" is the effective socialization and integration of fundamental radiographic physics principles into the established quality assurance systems. Understanding the stages of adoption, the characteristics of the innovation, the communication channels, and the nature of the social system are crucial for successful implementation (Rogers, 2. Furthermore, the research draws upon established quality management principles, such as those outlined by Deming's System of Profound Knowledge, which emphasizes understanding variation, systems thinking, and the importance of knowledge in improving processes (Deming, 1. Specifically, this study focuses on the interplay between technical knowledge . adiographic physic. , systemic implementation . uality assuranc. , and human factors . ocialization and adoption of practice. The primary constructs investigated include the level of understanding of fundamental radiographic physics principles .

The core theoretical framework posits that enhanced understanding of fundamental radiographic physics principles, facilitated through effective socialization processes within the quality assurance system, will lead to improved quality assurance practices in diagnostic Specifically, we hypothesize that a higher degree of socialization of radiographic physics principles will positively correlate with more robust quality assurance procedures and ultimately contribute to improved diagnostic image quality and radiation safety (Wondemagegn et al. , 2. The justification for this relationship stems from the premise that a deeper comprehension of the physical basis of radiography enables healthcare professionals to better identify, troubleshoot, and rectify issues related to image acquisition, processing, and dose For instance, understanding X-ray beam characteristics and their interaction with patient anatomy allows for more informed adjustments to exposure factors, directly impacting image contrast and noise levels (Suryana et al. , 2. Similarly, knowledge of radiation attenuation principles is essential for effective patient positioning and collimation, minimizing unnecessary radiation dose to non-target tissues (Fatimah et al. , 2. Without this foundational understanding, quality assurance efforts may remain superficial, focusing on compliance rather than genuine improvement (Mishra et al. , 2. Therefore, the primary objective of this research is to assess the current state of socialization and integration of fundamental radiographic physics within the quality assurance systems of hospitals and Puskesmas in Kabupaten Toba. This overarching objective will be addressed through the following specific research questions: . What is the level of understanding of fundamental radiographic physics principles among healthcare professionals involved in diagnostic radiology services in Kabupaten Toba? . How are these principles currently socialized and integrated into the existing quality assurance frameworks in these facilities? . What are the perceived barriers and facilitators to the effective socialization and integration of radiographic physics in quality assurance? . What is the relationship between the level of socialization of radiographic physics and the current quality assurance practices in diagnostic radiology? This study aims to make a significant contribution to the existing body of knowledge by providing empirical data on a critical but often overlooked aspect of healthcare quality in a specific Indonesian context. The findings are expected to inform the development of targeted training programs, policy recommendations for the Ministry of Health and local health authorities, and best practice guidelines for healthcare facilities seeking to enhance the quality and safety of their diagnostic radiology services (Hidayat & Lestari, 2. Ultimately, this research seeks to bridge the gap between theoretical knowledge of radiographic physics and its practical application in ensuring patient-centered, high-quality medical imaging services in Kabupaten Toba and potentially other similar regions facing comparable challenges. METHOD This study employed a mixed-methods sequential explanatory design, selected to maximize the strengths of both quantitative and qualitative approaches and thereby provide a comprehensive understanding of the phenomenon under investigation. The quantitative phase was conducted first to measure the level of knowledge and the perceived implementation of basic radiography physics principles among healthcare professionals. This was followed by a qualitative phase, which explored the underlying reasons, challenges, and facilitators of integration, offering deeper context and richer insights into the observed quantitative patterns. The sequential structure ensured that qualitative data collection and analysis were informed by the quantitative findings, enhancing the explanatory depth of the research. This approach was particularly relevant as the study aimed not only to assess the status quo but also to understand the social and practical dynamics of embedding technical knowledge into existing quality assurance systems. The research examined three core variables, namely knowledge of basic ISSN: 2829-7369 | DOI: 10. 47652/hablumminannas.

Page: 99-109 radiography physics principles, integration of radiography physics into quality assurance systems, and perceived barriers and facilitators of such integration. Knowledge referred to the understanding of fundamental concepts such as radiation physics, image formation, radiation protection, and quality control, which was measured using structured questionnaires assessing recall and application. Integration denoted the extent to which radiography physics principles were embedded into established quality assurance protocols and practices, operationalized through documentation reviews, direct observation, and professional perceptions. Meanwhile, perceived barriers and facilitators captured the subjective experiences of professionals regarding factors that hindered or promoted integration, explored through semi-structured interviews and focus group discussions. The decision to adopt this mixed-methods approach was motivated by the need to capture both the Auwhat,Ay reflected in quantitative measures, and the Auwhy,Ay reflected in qualitative insights, ensuring a holistic understanding of the research problem. A stratified random sampling strategy was applied to select healthcare facilities in Toba Regency, ensuring representation from both hospitals and community health centers (Puskesma. Within these facilities, purposive sampling was used to identify key informants such as radiographers, medical physicists where available, radiology department heads, and quality assurance officers. Power analysis determined that at least 150 participants were required for the quantitative phase to detect meaningful differences, while approximately 20 to 25 participants were recruited for the qualitative phase to ensure data saturation across diverse roles and levels of experience. Inclusion criteria consisted of being employed in a healthcare facility in Toba Regency, being directly involved in diagnostic radiography or quality assurance, and providing informed consent. Exclusion criteria included individuals on extended leave or those not directly related to radiography or quality assurance. Data collection was conducted in sequence, beginning with a self-administered questionnaire distributed both electronically and in hard copy, preceded by a pilot study to refine question clarity and flow. The qualitative phase followed, consisting of semi-structured interviews and focus group discussions conducted in private settings at participantsAo convenience and recorded with permission. The interview guide was informed by the initial quantitative findings and focused on areas requiring deeper exploration. All data collectors were trained using standardized protocols to ensure consistency, while recruitment, instrument administration, and recording procedures were clearly documented to guarantee The quantitative instrument was a structured questionnaire designed specifically for this study and informed by established literature on quality assurance in medical imaging and knowledge assessment in healthcare. It comprised two sections: demographic and professional background, and knowledge assessment items covering X-ray production, beam quality, image receptor characteristics, radiation dose, and fundamental principles of radiation protection such as ALARA. Content validity was confirmed through expert reviews by radiologists and medical physicists, while reliability testing yielded a CronbachAos alpha of 0. 85, indicating good internal For the qualitative phase, a semi-structured interview guide with open-ended questions was used to elicit detailed insights into participantsAo understanding of radiography physics, its application in quality assurance, the challenges encountered, and possible solutions. The guide was pilot-tested to ensure clarity and relevance, with no pre-existing instruments employed as it was specifically developed for this exploratory context. Data analysis combined quantitative and qualitative approaches. Quantitative data were processed using SPSS version 25. Descriptive statistics such as frequencies, percentages, means, and standard deviations summarized demographic characteristics and knowledge levels, while inferential analyses including t-tests and ANOVA were used to compare knowledge and integration practices across Pearson correlation coefficients were calculated to examine relationships between knowledge levels and integration. Assumptions of normality and homogeneity were checked, and where violations occurred, appropriate non-parametric tests or data transformations were Qualitative data, consisting of verbatim transcripts from interviews and focus groups.

The overall mean knowledge score of 62. 5 (SD = 15. suggests a moderate level of understanding among participants. However, a notable difference was observed between participants from hospitals (Mean = 68. SD = 13. and those from Puskesmas (Mean = 56. = 16. This difference indicates a potential disparity in knowledge levels across different types of healthcare facilities. Furthermore, an examination of correlations between key variables was conducted to understand potential relationships.

More importantly, a strong positive correlation was observed between facility type and knowledge score . = 0. 51, p < 0. This finding strongly supports the observation from the descriptive statistics, suggesting that working in a hospital environment is associated with higher knowledge levels compared to working in a Puskesmas. These patterns are directly relevant to understanding the distribution of knowledge and potential areas for targeted intervention. Precision of Main Analysis Results To formally test Hypothesis 1 (H. and explore the factors influencing knowledge levels, an independent samples t-test was conducted comparing the knowledge scores of hospital-based professionals versus those in Puskesmas.

Page: 99-109 indicated that radiologists (M = 75. SD = 10. had significantly higher knowledge scores than radiographers (M = 61. SD = 14. 80, p = 0. No significant difference was found between radiologists and QA officers, or between radiographers and QA officers. This finding, while not directly hypothesized, provides valuable insight into knowledge distribution within professional To further investigate the factors influencing knowledge and perceived integration, a multiple regression analysis was conducted. The dependent variable was the overall knowledge score, with facility type and years of experience as independent variables. The model was statistically significant. RA = 0. , . = 10. 30, p < 0.

This qualitative data provides a richer context for the quantitative findings. Furthermore, a robustness check was performed by re-analyzing the data after removing participants with less than one year of experience. The significant differences observed in knowledge scores between facility types and the predictive power of facility type remained consistent, indicating that the findings are not solely driven by very junior staff. An exploratory analysis was conducted to examine the potential moderating effect of professional role on the relationship between facility type and knowledge score. While the interaction term was not statistically significant . = 0. , the trend suggested that the advantage of being in a hospital setting might be slightly more pronounced for radiographers compared to radiologists, though this requires further investigation with a larger sample. Coherent Summary of Results In summary, the findings of this study reveal a moderate overall knowledge level of basic radiography physics among healthcare professionals in Toba Regency, with a significant disparity between hospital-based and Puskesmas-based professionals. The research strongly supports the hypothesis that professionals working in hospitals possess higher knowledge scores, likely due to better access to resources and training. The analysis also confirms the perceived gap in the systematic integration of basic radiography physics principles into existing quality assurance protocols, as indicated by low agreement scores on relevant survey items.

Page: 99-109 include the lack of specialized training and inadequate resources, while management support and professional development are seen as crucial facilitators. The study's results collectively underscore the need for targeted socialization and integration of basic radiography physics knowledge to enhance the quality assurance of diagnostic imaging services, particularly in Puskesmas. These findings provide a solid foundation for the subsequent discussion on implications and recommendations. CONCLUSION This research successfully achieved its objectives by comprehensively examining the effectiveness of socializing the integration of basic radiography physics within health quality assurance systems at both hospital and community health center (Puskesma. settings in Kabupaten Toba. The findings of this study can be synthesized into three key insights. First, structured and contextually relevant socialization initiatives significantly enhanced the knowledge and understanding of medical and technical staff regarding the principles of basic radiography physics, thereby addressing the core research question on the efficacy of educational This improvement demonstrates that targeted knowledge transfer can effectively bridge critical competency gaps in the operationalization of radiography quality assurance. Second, substantial heterogeneity was identified in both the level of understanding and the success of implementation between hospitals and Puskesmas, closely linked to disparities in resources, infrastructure, and technical capacity. This highlights the inherent challenges in standardizing practices across different levels of healthcare service delivery and emphasizes the need for adaptive approaches tailored to institutional contexts. Third, several barriers to integration were identified, including the scarcity of specific and contextualized training materials, limited staff availability to engage in socialization activities, and inadequate technical These factors directly align with the studyAos objective to uncover implementation obstacles and inform practical solutions. The contributions of this research are significant, both theoretically and empirically. Theoretically, the study enriches existing literature by presenting a conceptual model that links the mastery of radiography physics principles to the effectiveness of quality assurance systems in primary and secondary healthcare facilities. It demonstrates how abstract physics concepts can be operationalized into tangible practices that enhance diagnostic quality and patient safety. Empirically, the study provides robust evidence of knowledge gaps and contextual barriers faced by healthcare institutions in resource-limited regions. The original contribution lies in the nuanced analysis of the challenges experienced by hospitals and Puskesmas in adopting radiography QA practices, offering recommendations grounded in field realities rather than generic models. From a practical standpoint, several implications are paramount. Training and socialization materials must be more specific, context-driven, and easily accessible, with an emphasis on case-based learning and hands-on demonstrations. Adequate financial and time resources must be allocated for continuous training and refresher programs, supported by both local government and healthcare management. Furthermore, technical support must be strengthened, accompanied by the provision of standardized quality measurement tools and enhanced access to expert consultation in medical physics and radiology. This research also opens avenues for future inquiry. Longitudinal studies are needed to assess the sustained impact of radiography physics training on image quality, radiation dose reduction, and operational Comparative research exploring different models of socialization such as face-to-face instruction, online learning, and mentorship would help identify the most effective strategies for diverse healthcare settings. Additionally, investigations into the role of organizational culture and leadership in sustaining QA practices will yield deeper insights into institutional readiness and long-term ISSN: 2829-7369 | DOI: 10. 47652/hablumminannas.
