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

Penggunaan flipbook menjadikan pembelajaran lebih menarik, interaktif, dan komunikatif di dalam kelas. Hasil belajar yang diiginkan guru merupakan keterampilan berpikir tingkat tinggi (HOTS). Jenis penelitian ini adalah penelitian tindakan kelas atau PTK (Classroom Action Research). SMKS Mutiara Ilmu adalah lokasi sekolah yang dijadikan sebagai tempat penelitian. Penelitian ini dilakukan pada bulan Oktober - November semester ganjil tahun ajaran 2023/2024. Populasi dalam penelitian ini adalah siswa kelas X yang berjumlah 165 sedangkan sampelnya adalah siswa kelas X PPLG yang berjumlah 30. Dalam penelitian ini menggunakan teknik pengumpulan data berupa observasi terhadap keterlaksanaan pembelajaran dan menggunakan tes hasil belajar yang berorientasi pada soal-soal HOTS berupa soal essay pada tingkat pengetahuan C4 dan C5. Soal essay yang diberikan pada siklus 1 sebanyak 3 soal dan soal yang diberikan pada siklus 2 sebanyak 4 soal. Pada Siklus I menunjukkan siswa yang telah berhasil dalam belajar sebesar 46,67% sedangkan pada siklus II meningkat menjadi 90%. Hal ini dapat dilihat dari persentase peningkatan siswa yang telah berhasil dalam belajar pada siklus I sebesar 46,67% meningkat menjadi 90% pada siklus II. Dengan demikian penelitian ini menunjukkan terjadinya peningkatan hasil belajar melalui pembelajaran berorientasi HOTS berbantuan filpbook.

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.
