Abstract

Muslim concerning divine assurance (Divine Assurance) for the endurance of the Muslim ummah. Employing a qualitative library research method with a hermeneutic approach, this research analyzes classical commentaries and contemporary interpretations to explore the relevance of the hadith to Islamic education and community resilience. The findings reveal that divine assurance emphasizes collective protection rather than individual immunity, signifying that the strength of the ummah lies in unity, moral integrity, and spiritual awareness. Internal division, moral degradation, and loss of faith are identified as dominant factors that threaten Islamic civilization. The study also finds that the hadith provides a pedagogical foundation for strengthening Islamic brotherhood., Islamic ethics, and character formation through education based on faith and morality. The conclusion asserts that Islamic education must serve as an instrument of ummah resilience, integrating faith, knowledge, and ethics to produce the man of adab humans of virtue, intellect, and social responsibility capable of preserving unity and reviving Islamic civilization amid modern global challenges.

Abstract

Transformers are one of the most important equipment in electrical power systems. Transformer failure at power plants can interrupt the continuity of electricity supply. Therefore, monitoring the condition and early detection of transformer damage is important to ensure that transformers can work properly until their maximum service life. One type of damage that can occur is a change in the mechanical structure of the transformer's internal components. This damage can be detected using the Sweep Frequency Response Analysis (SFRA) method, which is a non-invasive testing technique that analyzes changes in frequency response due to internal mechanical disturbances. This study conducted an SFRA analysis on power transformers at the Tenayan Raya Power Plant by comparing the conditions before and after repairs. Comparisons across three test periods showed that the most notable variations occurred between 2020 and 2022, mainly at high frequencies, indicating winding deformation due to operational stress. In contrast, the pre- and post-maintenance comparison revealed stable responses, confirming that maintenance activities did not cause significant deformation.
