Abstract

Fisika dan biologi, meskipun tampak sebagai disiplin ilmu yang berbeda, memiliki keterkaitan yang erat dalam menjelaskan fenomena alam yang terjadi di dunia hidup. Penerapan hukumhukum fisika dalam biologi memberikan wawasan mendalam mengenai berbagai proses biologis yang kompleks, dari tingkat molekuler hingga tingkat organisme. Dalam penelitian ini, dibahas bagaimana prinsip-prinsip fisika, seperti mekanika, termodinamika, dan elektromagnetisme, berperan penting dalam memahami berbagai fenomena biologis, seperti transportasi molekul melalui membran sel, mekanisme pernapasan, serta peran energi dalam proses metabolisme. Dengan mengaplikasikan hukum fisika pada sistem biologis, kita dapat mengembangkan model matematis yang lebih akurat untuk menjelaskan dan meramalkan perilaku sistem biologi, serta meningkatkan pengembangan teknologi medis dan bioteknologi. Penelitian ini juga menyoroti pentingnya pendekatan interdisipliner yang menggabungkan fisika dan biologi dalam menghadapi tantangan-tantangan ilmiah dan teknologi di masa depan.

Abstract

Purpose This research aims to explore the effects of X-ray radiation on atomic structure from a physics perspective, with an emphasis on how the interactions take place, their effects on electron configurations, and the physical consequences that arise. This review aims to communicate a deeper understanding of how X-ray radiation changes atomic dynamics and the underlying mechanisms, by combining the results of recent research. Design/Methods/Approach The research approach uses a systematic literature review methodology, which involves the identification, selection, and analysis of relevant academic materials. The sources examined include theoretical and experimental studies related to X-ray interaction mechanisms, such as photoelectric phenomena, Compton scattering, and pair production. This approach allows for a critical analysis of previous results and the integration of data to provide a comprehensive understanding of the physical effects of X-ray radiation on atomic structure. Findings TThe findings of this review indicate that X-ray radiation can cause ionization of atoms, excitation of electrons, and also changes in subatomic particles at high energy levels. The photoelectric effect serves as the main mechanism affecting the arrangement of electrons in atomic shells, while Compton scattering shows the change in photon energy due to interaction with free electrons. Pair production is observed at very high X-ray energy levels, indicating the conversion of radiation energy into new particles. Research Implications/Limitations The implications of this study include enriching the understanding of radiation physics and developing technologies that use X-ray radiation for scientific and industrial purposes. However, there are limitations to this study, namely the lack of direct experimental evidence to support certain literature analyses. Additional research is needed to deepen the understanding of the complex interactions between X-ray radiation and atomic structures, especially under extreme conditions.

Abstract

The era of digital transformation has brought fundamental changes to the banking industry in Indonesia, encouraging banks to optimize information systems to improve service quality and maintain customer loyalty. This study focuses on Bank Rakyat Indonesia (BRI) in Medan City, which is the economic center of North Sumatra with a high level of competition. In this context, information system audits are important to assess the reliability, security, and effectiveness of existing systems. This study aims to evaluate the effect of service quality and customer satisfaction on BRI customer loyalty, as well as to analyze the impact of information technology implementation in improving service quality. The methods used in this study include qualitative and quantitative analysis, with data collection through questionnaires distributed to BRI customers in Medan. The results of the study indicate that there is a significant effect between service quality and customer satisfaction on loyalty. In addition, the digital transformation carried out by BRI, including the implementation of the COBIT and ISO 31000 frameworks, has improved operational efficiency and data security. However, BRI also faces challenges in adapting to changing regulations and strengthening cybersecurity systems. These findings provide valuable insights for BRI management in optimizing more effective information systems and marketing strategies, and emphasize the importance of a customer-centric approach in improving customer experience. Recommendations for BRI include strengthening risk management and utilizing demographic data for more targeted product development, in order to maintain customer loyalty in the increasingly digital era.
