Cyclone separator dapat digunakan untuk memisahkan fasa solid dan gas serta dapat mengklasifikasikan partikel berdasarkan ukuran. Terdapat banyak parameter geometris dan operasional yang mempengaruhi kinerja cyclone, salah satunya modifikasi geometri untuk memperoleh kinerja yang lebih efisien. Pada penelitian ini ditambahkan blade cross shape pada vortex finder dengan variasi lebar 0 mm, 5 mm, dan 10 mm, vortex finder thickness di variasikan dengan ukuran 1 mm, 5 mm, 10 mm, dan 15 mm. Kedua variasi ini disimulasikan dengan menggunakan Computational Fluid Dynamics (CFD) untuk mengetahui pengaruh variasi tersebut terhadap medan aliran dan peforma yang terjadi pada new cyclone separator. Reynold stress model (RSM) digunakan untuk mensimulasikan aliran yang terjadi. Pendekatan Eulerian-Lagrangian digunakan untuk memprediksi pergerakan partikel pada new cyclone. Metode Rosin-Rammler digunakan dalam simulasi numerik untuk menerapkan Particle Size Distribution (PSD). Hasil simulasi menyatakan bahwa bertambahnya vortex finder thickness dan lebar blade cross shape dapat meningkatkan efisiensi pengumpulan dan menurunkan nilai pressure drop new cyclone separator dengan hasil terbaik memiliki nilai efisiensi pengumpulan sebesar 92,03% dan nilai pressure drop sebesar 194.23 Pa.

This study explores the Gelaran Parowulan as a manifestation of prophetic art that integrates religious, cultural, and socio-political expressions in Tegal, Indonesia. Using a descriptive phenomenological approach, the research examines how this grassroots movement employs traditional art forms—such as poetry, puppetry, and dance—to convey Islamic values while addressing societal challenges. The findings highlight three key aspects: the socio-political critique inherent in performances, the aesthetic expression of religious experiences, and the embodiment of Islam's spirit of raḥmatan li al-‘ālamīn (mercy to all creation). Gelaran Parowulan not only revitalizes local art forms but also fosters inclusivity and solidarity among diverse communities. By rejecting formalism and promoting sincere engagement, this movement redefines da'wah as a dynamic, creative, and accessible practice. The study underscores the transformative potential of prophetic art in fostering harmony and addressing contemporary social issues.

This study examines the values of local wisdom in Tafsīr al-Bayān by Shodiq Hamzah and its role in promoting peace through tolerance, respect for traditions, and non-violence. Written in Javanese using Latin script while preserving the pesantren Pegon tradition, this work reflects a synthesis of Islamic scholarship and local culture. Employing qualitative library research, the study uses the concept of local wisdom as a framework for peacebuilding within religious moderation. A thematic approach identifies and analyzes Qur’anic verses on peace, interpreted through Shodiq Hamzah’s perspective. The findings reveal that Shodiq Hamzah integrates values like compassion, justice, and wisdom into social interactions while advocating for moderate religious reasoning. His interpretation underscores the importance of local wisdom in resolving interfaith conflicts and fostering harmony. This research enriches the literature by illustrating how religious moderation rooted in local traditions provides a sustainable framework for addressing societal challenges. Tafsīr al-Bayān bridges textual interpretation with cultural context, highlighting the dynamic interplay of Islamic teachings, local wisdom, and contemporary issues, making it a key reference in studies on peace and religious moderation.

This article explores the contextual meaning of jilbāb and khimār in the Qur’an by integrating Hans-Georg Gadamer’s hermeneutics and the classical framework of ‘ulūm al-Qur’ān (the sciences of Qur’anic interpretation). The study addresses the central problem of how verses on jilbāb (Q.S. al-Aḥzāb [33]: 59) and khimār (Q.S. an-Nūr [24]: 31) can be interpreted through the fusion of horizons between text and reader, especially in light of contemporary gender and modesty discourses. Using descriptive-analytical library research, this article draws from primary sources—the Qur’an and Gadamer’s philosophical works—alongside secondary references on tafsir and hermeneutics. The findings reveal that jilbāb and khimār are best understood as protective-preventive measures rooted in both historical context and ethical intentions. Rather than prescribing fixed models of clothing, the Qur’anic injunctions emphasize dignity, modesty, and the social protection of women. By applying Gadamer’s key concepts—effective history (Wirkungsgeschichte), pre-understanding (Vorverständnis), and fusion of horizons (Horizontverschmelzung)—the study demonstrates how traditional interpretations may evolve through dialog with present-day realities. This approach contributes to the ongoing discourse on gender, religious norms, and the role of interpretation in Islamic scholarship.
