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

The purpose of implementing this community service activity is to provide understanding, knowledge and the importance of developing the Syiah Kuala University Campus (USK) as a means of education. The method used is the lecture method, which describes the material that has been prepared, the question and answer method, which is to respond to the level of understanding of the participants' understanding of what has been conveyed and the discussion method, namely the presenter and participants have a dialogue that discusses issues around USK Campus II. While the targets of this activity are community leaders from Neuheun Village, Durung Village, and Ladong Village, Mesjid Raya District, Aceh Besar Regency. The results obtained are expected to build awareness and increase public understanding of the importance of developing Campus II Syiah Kuala University as an educational facility.

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

Melia azedarach L. (neem fruit) is a traditional plant with diverse bioactive constituents, yet its phytochemical profile and pharmacological potential remain underexplored. This study aimed to screen bioactive compounds and evaluate the antioxidant activity of methanol extract from M. azedarach fruit, while further performing computational exploration on its antidiabetic potential. M. azedarach fruits were macerated in methanol and analyzed through phytochemical screening, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity (DPPH assay). GC-MS was used to identify chemical constituents. Molecular docking was performed using a blind docking approach in CBDock2 against five protein targets, which included DPP-4, PTPN1, α-amylase, NrfA, and AKR1B1. Protocol validation was ensured by successful re-docking of co-crystallized ligands (RMSD < 2.0 Å). The extract was observed to contain terpenoids, steroids, flavonoids, and phenolics, with high TPC (479.8 mg GAE/g) and TFC (52.7 mg QE/g). Antioxidant activity was moderate (IC50 = 102.27 µg/mL). GC-MS identified 14 compounds, including cucurbitacins, ursolic acid derivatives, α-amyrin, taraxasterol, and ergostane-type sterols. Docking revealed moderate affinities (–5.0 to –6.5 kcal·mol-1) for most compounds. The cucurbitacin bound α-amylase (–13.6 kcal·mol-1) and NrfA (–8.5 kcal·mol-1), and taraxasterol exhibited broad-spectrum activity across all targets (–7.1 to –9.2 kcal·mol-1). M. azedarach fruit demonstrates moderate antioxidant activity and contains diverse phytochemicals with multitarget interactions relevant to glucose regulation. Strong binding to DPP-4, PTPN1, α-amylase, and AKR1B1 suggests potential antidiabetic properties through inhibition of carbohydrate digestion, enhancement of insulin signaling, and prevention of diabetic complications.
