Abstract

Regarding the use of hydrogen in fuel cell for mobile or stationary applications, metal hydrides can offer a high hydrogen volume capacity and a safe alternative compared with liquid storage or with compressed gas. Among the metal hydrides, magnesium is considered as one of potential hydrogen storage materials because of its high capacity (7.6 wt%), lightweight and low cost. However, high work temperature would slow down kinetics reaction and harden activation process limit practical application of Mg-based hydrides as well. Recently, the high energy ball milling was successfully introduced to prepare hydrogen storage materials. In this work, MgH2 catalyzed with Ni nanoparticles was synthesized by planetary type ball milling under high pressure of hydrogen at 100 bar (10 MPa). As a result, small amount of Ni in nanometer scale acts as a suitable catalyst for kinetics improvement of MgH2 which could absorb 5.3 wt% of hydrogen within 5 minutes at 300ºC. It is obvious that small amount Ni (2 mol%) has much better catalyst than catalyst in nanoparticle size; and at the same time, it is allowed to reduce the milling process for short time (2 hours).

Abstract

Sebagian orang menganggap terjadinya gerhana matahari merupakan hal yang istimewa dan mengagumkan. Sehingga fenomena gerhana sering disangkut pautkan dengan kelahiran maupun kematian, padahal kejadian ini terjadi disebabkan bulan menutup matahari, sehingga cahaya matahari tidak sampai ke bumi. Kalimat bulan menutup matahari sepertinya hal yang mustahil mengingat diameter matahari  lebih besar dari pada bulan, tetapi jika kita membandingkan jarak matahari dari bumi dengan jarak bulan dari bumi, ini bukanlah hal yang mustahil. Sehingga gerhana merupakan hal yang sederhana, kerena proses terjadinya dapat digambarkan dengan jelas. Dalam tulisan ini peneliti mencoba menggambarkan proses terjadinya gerhana matahari berdasarkan sains, QS. Al – Baqarah [2] :189, QS. Yunus [10] : 5, QS. Yasin [36] : 39 dan 40. Maka dapat disimpulkan bahwa (1) bulan baru terjadi setiap  hari, (2) Bulan sabit menjadi tanda bahwa esok merupakan bulan baru, (3) Orbit bulan berbentuk elips, sehingga jarak bulan dengan bumi tidak konstan, ini yang menyebabkan terjadinya gerhana matahari total, cincin dan sebagian, (4) bumi, bulan, matahari dan benda – benda langit lainnya bukanlah sebuah tubuh yang kaku, namun memiliki akal.

Abstract

Development of a carbon electrode sensor from used tire waste via pyrolysis, modified with ethylenediaminetetraacetic acid (EDTA) for mercury detection using the cyclic voltammetry (CV) method. EDTA plays a role in metal complexation due to its strong response to mercury metal. The FTIR results of the carbon electrode and EDTA show a C–N bond at a wavenumber of 1,217.08 cm−1, indicating the presence of EDTA. The SEM results reveal a clear difference between the unmodified carbon electrode and the EDTA-modified carbon electrode. The calibration graph is linear, with an R2 value of 0.9961, a sensitivity of 0.3472, as well as LoD and LoQ values of 0.03 and 0.08 ppm, respectively. The correlation coefficient is less than 2%, and the %recovery is within the allowable error range. Mercury measurements in Sungai Mas water samples, Aceh Barat, using voltammetry and AAS, exceed the threshold set by Indonesian Government Regulation (PPRI) No. 22 of 2021. The t-test results for the two Hg measurement methods at a 5% significance level (α) show that tcalculated < ttable (0.083 < 2.571). This indicates no significant difference between the voltammetry and AAS methods for measuring Hg concentrations in water.

Abstract

This study examines the practice of integrated education in Aceh Besar, Indonesia, a region with strong Islamic traditions and the implementation of Islamic law, to explore how religious values are internalized while simultaneously fostering social cohesion and using a qualitative multiple case study design. This research was conducted at SMP Negeri 1 Darul Imarah, SMP Negeri 1 Ingin Jaya, SMP Negeri Ali Hasjmy (a boarding school), SMP Negeri 1 Darussalam, SMP Negeri 1 Kuta Baro, and SMP Negeri 3 Ingin Jaya. The method used was a qualitative approach, with data collected through in-depth interviews, focus group discussions, and document analysis. Data were analyzed thematically to identify patterns and mechanisms through which Islamic education translates into social practices. The findings reveal three interrelated mechanisms: (1) the internalization of Islamic values is promoted through curricula and activities that incorporate local wisdom, such as meuseuraya; (2) social cohesion is strengthened through structured collaboration between schools, families, and community institutions, enabling students to practice empathy, cooperation, and civic responsibility; and (3) normative Islamic teachings are connected to contemporary educational needs, including ethical engagement with modern social and digital contexts. These mechanisms function as a coherent educational ecosystem in which ethical development and community integration mutually reinforce one another. The study demonstrates that integrated education can operationalize universal Islamic principles within culturally relevant frameworks, translating moral values into practical social behaviors. While situated in Aceh Besar, the findings highlight processes by which Islamic education can bridge spiritual formation and social cohesion in contexts where religion and local culture intersect.
