Abstract

Chlorophyll compounds have been widely developed in photoinactivation research as organic photosensitizer agents, especially those extracted from green plants. Besides being natural and containing antimicrobial substances, the characteristic electronic properties of chlorophyll atomic have a long lifetime at the triplet level, so it is highly probable to produce Reactive Oxygen Singlet (ROS) while light activates. This phenomenon can potentially be applied in the mechanism of Photodynamic Therapy (PDT) or Photodynamic Inactivation (PDI) in various types of pathogenic bacteria that trigger infectious diseases. Laser light that activates photosensitizer molecules produces singlet oxygen which is reactive and toxic to microbial pathogens. In this study, will be found the efficacy of Jatropha leaf extracts combinate nano silver to inactivate biofilm cells of Staphylococcus epidermidis after being inducted by a red laser. Analysis of the research data quantitatively and qualitatively described the reduction in the number of biofilm cells and damage to the morphology of the biofilm cells with various energy radiant lasers applied through a scanning electron microscope (SEM) profile. The results showed that the photosensitizer agent, which combined Jatropha extracts with nano silver, obtained an inhibitory effect of 60% for the non-oxygenated group and 80% for the oxygenated group.

Abstract

This study investigates the decline of three major Islamic empires in the 18th century—the Ottoman Sultanate, the Safavid Dynasty, and the Mughal Dynasty—which had previously attained prominence in political, military, and cultural spheres. The research aims to analyze the internal and external factors that led to the political fragmentation of these empires. Adopting a qualitative approach with a historical-comparative method, the study relies on literature-based data, which were analyzed through five stages: heuristics, verification, interpretation, comparison, and historiography. The findings indicate that the decline of these empires resulted from an interplay between internal weaknesses, including leadership crises, succession conflicts, and the decentralization of power, and external pressures stemming from European colonial expansion and transformations in the global economic system. The study concludes that, despite political fragmentation, the cultural and religious legacies of these empires continue to shape the development of the Islamic world in contemporary contexts. The research contributes to a deeper understanding of the transition from cohesive imperial power to fragmented political entities and elucidates broader changes in global dynamics during this period.

Abstract

This research examines the relationship between the concept of equilibrium in physics and the implementation of Islamic governance, and how the two concepts relate to each other in the context of an Islamic state. In physics, equilibrium is achieved through the interaction of various forces within a system that continuously strives for stability, both in static and dynamic systems. This parallels the efforts of Islamic governments to maintain a balance between state authority, individual rights, and social obligations. Islamic governments emphasize the importance of social justice, reflected in state policies based on Sharia law, which aim to ensure social welfare by equitably considering individual rights and societal interests. In this study, the authors found that Islamic governance must be able to adapt to changing times and social dynamics, similar to the principle of equilibrium in physics, which always strives to achieve a stable state despite change. Socio-economic policies such as zakat and waqf serve to reduce social inequality, while the moral and ethical principles of sharia play a crucial role in maintaining this balance. This study concludes that the concept of equilibrium in physics provides a useful perspective for understanding the dynamics of Islamic governance, which is not merely static but also dynamic and adaptive to the demands of the times and the needs of society.

Abstract

This study addresses the limited availability of instructional media that integrate scientific content with spiritual values in physics education. It aims to develop and validate digital flipbook-based teaching materials for Basic Physics using the STEM-Qur’an (STEMQ) approach. The objective is to produce educational content that combines scientific accuracy, interactive digital design, and the integration of Qur’anic principles to foster ethical and holistic learning. A descriptive validation method was applied involving expert judgment to evaluate two main dimensions: content validity and media quality. Content evaluation focused on curriculum alignment, conceptual accuracy, language clarity, instructional structure, and STEMQ integration. Media validation assessed digital layout, implementation practicality, and technological functionality. Data were analyzed using the Gregory Index, resulting in a coefficient of 0.90 for content and 0.83 for media, indicating high validity. The findings confirm that the flipbook is pedagogically sound, technologically usable, and culturally relevant for Islamic science education. This validated model supports the integration of empirical inquiry with Qur’anic values and offers a framework for future development and classroom application
