Abstract

The completion of a final project is an essential component of higher education and often presents significant challenges for students, including those in the Physics Study Program at Universitas Jambi. Various obstacles, such as difficulties in selecting research topics, formulating research problems, designing research methodologies, and producing academic writing in accordance with scientific standards, may hinder the timely completion of studies. Therefore, this community service activity aimed to enhance students' understanding of research skills and final project writing through a webinar on research and scientific writing enhancement. The activity was conducted online via Zoom Meeting on November 20, 2025, involving students from the Physics Study Program of Universitas Jambi. The methods employed included training and academic assistance through lectures, discussions, and interactive question-and-answer sessions. The effectiveness of the activity was evaluated using pre- and post-webinar questionnaires. The results indicated an improvement in participants' understanding across all assessed aspects. The average percentage of participants categorized as not understanding and having low understanding decreased from 10.92% and 45.22% to 0.92% and 14.44%, respectively. In contrast, the average percentage of participants categorized as moderately understanding and highly understanding increased from 34.78% and 8.54% to 49.32% and 37.16%, respectively. These findings demonstrate that the webinar effectively improved students' understanding of final project preparation. Similar activities should be conducted continuously to support the improvement of scientific writing quality and the timely completion of students' studies.

Abstract

Fe₃O₄ nanoparticles were synthesized via a green route using Pleomele angustifolia leaf extract as a bio-reducing and capping agent. XRD analysis confirmed the structure of pure cubic spinel magnetite phase with nanoscale crystallite sizes, while slight lattice variations indicate surface interactions with phytochemicals. SEM images revealed quasi-spherical nanoparticles with average particle sizes of 53–63 nm, where increasing extract concentration reduced agglomeration and improved dispersion. FTIR spectra showed characteristic Fe–O vibrations together with hydroxyl, carbonyl, and aliphatic functional groups, confirming effective surface functionalization by plant-derived compounds. These results demonstrate that Pleomele angustifolia extract regulates nucleation, growth, and surface chemistry during Fe₃O₄ nanoparticle synthesis, highlighting its potential as a sustainable synthesis route for magnetic nanomaterials.

Abstract

The study focused on preparing and characterizing Calcium Carbonate (CaCO3) derived from the shells of Lombok pearl oysters (Pinctada Maxima). The objective was to assess the potential of these shells as raw material for Thermochemical Energy Storage (TCES). The research involved calcination pearl oyster shells at different temperatures: 600°C (CKM 1), 700°C (CKM 2), and 800°C (CKM 3). XRD analysis revealed that these samples contained CaCO3 with a calcite phase and a Rhombohedral crystal system (R-3C). The crystalline sizes for CKM 1, CKM 2, and CKM 3 were 53.70 nm, 57.05 nm, and 40.07 nm, respectively. Furthermore, pearl oyster shell samples were combined with Ludox. XRD results for samples subjected to filltering treatment (CKM 4) and heating treatment with a stirrer on a hotplate (CKM 5 and CKM 6) and calcined at 600°C and 700°C also indicated the presence of CaCO3. The crystalline size for CKM 4, CKM 5, and CKM 6 was measured at 55.50 nm, 55.51 nm, and 55.51 nm, respectively. CaCO3 from Pearl oyster shells have direct band with the value between 2.1 - 2.9 eV.
