Abstract

Barium titanat (BaTiO3) dengan struktur kristal prerovskite tetragonal telah dikenal bersifat material ferroelektrik. Material ini telah banyak digunakan dalam aplikasi di bidang elektronik seperti sensor, transduccers, infrared detector dan multi layer ceramic capacitor (MLCCs). Hai ini dikarenakan barium titaniat lebih ramah lingkungan, memiliki temperature curie (Tcurie ) yang lebih rendah daripada material dielektik lain, dan memiliki konstanta dielektrik yang tinggi. Untuk meningkatkan peforma barium titaniat, diperlukan partikel barium titaniat yang berukuran nano. Oleh karena itu dalam penelitian ini barium titaniat nano partikel distensis dengan menggunakan metode proses prekursor dengan plup merang (oryza sativa) sebagai template. Variasi temperatur kalsinasi (700 0c, 900 0c,1100 0c) dan konsentrasi perkursor (o,1 m dan 0,07 m) dilakukan untuk mengetahuipengaruh temperatur kalsinasi dan konsentrasi perkursor terhadap kristalisasi dan ukuran partikel barium titaniat. Berdasarkan hasil XRD, di ketahui bahwa pada temperatur kalsinasi 700 0c barium titaniat telah berbentuk dan seiring dengan peningkatan tempertatur kalsinasi, kristalisasi barium titaniat juga meningkat. Berdasarkan hasil SEM diketahui bahwa serbuk barium titaniat hasil sintetis telah berukuran nano. Dengan menurunkan konsentrasi prekursor menjadi 0.07 m, didapatkan sebuk barium titaniat yang lebih kecil bila dibandingkan dengan serbuk yang disintetis menggunakan konsentrasi prekursor 0.1 m.

Abstract

The development of information technology has driven a significant shift in the practice of hadith retrieval, from manual searches based on classical texts to the use of digital hadith databases that offer speed, accessibility, and ease of search. This shift, while providing methodological efficiency, raises complex epistemological issues, particularly regarding the validity of knowledge, scholarly authority, and the relationship between classical hadith methods and computational logic. This study aims to critically analyze the use of digital hadith databases in the process of narration verification, highlighting the accompanying epistemological implications. The study uses a qualitative-analytical method through an epistemological approach, supported by a review of classical and contemporary literature, as well as a critical analysis of a number of digital hadith platforms widely used in hadith studies. The results of the study indicate a shift in scientific authority from the individual competence of muḥaddith to technological authority that relies on data structures and algorithm design, the limitations of search algorithms in representing the complexity of sanad and matn, the fragmentation of the scientific context of hadith due to the separation of narration from its historical and methodological framework, and the fundamental tension between the evaluative-qualitative epistemology of ʻulūm al-Ḥadīs and the quantitative and reductionist digital logic. These findings confirm that digital hadith databases cannot yet replace the critical function of classical methodology, but rather act as supporting instruments that require a strict epistemological framework. Academically, this study has implications for the need to develop an integrative takhrīj model that synergizes traditional scientific authority with digital technology critically and reflectively in the digital era.
