Abstract

This research aims to produce N/S-doped Carbon Electrode derived from paper waste (NSCEp) for Electric Double-Layer Capacitor (EDLC). The paper waste holds potential as raw material for carbon production because of its high cellulose content, abundance of availability, and low price. To enhance the electrical performance of the carbon, an activation step was conducted, followed by double doping with nitrogen and sulfur using thiourea. The NSCEp result was analysed to examine its specific diffraction peaks, crystallinity, morphology, and elemental contents. The NSCEp powder was then mixed with dispersant to produce a homogeneous slurry for the electrode film. The EDLC was assembled in a sandwich-like structure, with sodium hydroxide (NaOH) solution impregnated in a separator between the carbon film electrodes. The EDLC assembly was conducted under an argon atmosphere in a CR2032 coin cell. The results found that the NSCEp provides a high electrical conductivity of 1.21 x 102 S/cm. The prepared EDLC achieved the specific capacitance value of 39.555 F/g as determined by cyclic voltammetry (CV) analysis. Furthermore, the EDLC demonstrates high initial charge-discharge capacities of 300.56 mAh/g and 248.88 mAh/g, respectively, at a current of 0.015 A/g. The capacity remains stable for up to 300 charge-discharge cycles.

Abstract

Katalis logam transisi periode pertama (Fe, Co, Ni, Cu, atau Zn) berbasis Hydrogen Zeolite Socony Mobil – 5 (HZSM-5) merupakan katalis yang menjanjikan untuk berbagai macam reaksi. Pada penelitian ini akan dipelajari keperiodikan aktivitas dan kestabilan struktur katalis tersebut pada reaksi cracking anisol. Uji katalitik dilakukan dengan menggunakan reaktor semi alir. Produk dari hasil proses cracking anisol dianalisis menggunakan kromatografi gas-spektra massa (GC-MS), kemudian karakter katalis bekas seperti kristalinitas dan komposisi fasa dianalisis menggunakan X-ray diffraction (XRD), sedangkan luas permukaan dan porositas dianalisis menggunakan surface area analyzer (SAA). Hasil penelitian menunjukkan bahwa tidak nampak kaitan antara sifat periodik unsur dengan aktivitas katalitiknya. Karakter setiap katalis yang telah digunakan mengalami sedikit perubahan pada komposisi fasanya, terutama katalis Fe/HZSM-5 dan Co/HZSM-5, sedangkan luas permukaan dan porositasnya mengalami penurunan.

Abstract

A study on graphene defects for hydrogen storage has been successfully conducted using the Density Functional Tight Binding (DFTB) approach. The research aimed to modify solid materials for hydrogen storage. A 4 × 4 × 1 unit cell was used as the basis, while the supercell used for sampling was enlarged to 40 × 40 × 1. The analyzed data included changes in Density of States (DOS), Fermi level shifts, electronic band structures, formation energy, adsorption energy, and isosurfaces for each graphene orientation. It has been observed that modifying the surface structure of graphene can alter the electronic properties of graphene. This is indicated by shifts in DOS intensity, characterized by increased electronic intensity around the Fermi level total density charge different. The interaction energy between graphene and hydrogen gas has been determined to be -0.0155 eV for H-epoxy graphene, -0.4941 eV for H-monovacancy graphene, and -0.0424 eV for HN-monovacancy graphene. The presence of the vacancy increase the potential to adsorp hydrogen.

Abstract

The integration of reading and writing has long been recognized as a crucial component in second language learning. However, most previous studies have focused primarily on linear academic texts, with limited attention to the role of multimodal reading materials in supporting students’ academic writing development. This study investigates how multimodal reading texts influence the academic writing development of English as a Foreign Language (EFL) students. Using a qualitative case study design, the study involved approximately 20–25 undergraduate students enrolled in an Academic Writing course in an English Language Education program. Data were collected through classroom observations, analysis of students’ writing samples, and semi-structured interviews. The data were analyzed using thematic analysis and qualitative discourse analysis to examine patterns in students’ perceptions and developments in their written texts. The findings reveal that exposure to multimodal texts such as infographics, visual essays, and digitally enriched articles enhances students’ ability to generate ideas, organize arguments, expand lexical choices, and engage critically in academic writing. Students also demonstrate an improved capacity to synthesize information from multiple modes into coherent written arguments. These results suggest that integrating multimodal reading materials into writing instruction can effectively support academic writing development in EFL contexts. However, the findings are limited to a single instructional setting and a relatively small participant group; therefore, caution should be exercised in generalizing the results. Nevertheless, the study provides transferable pedagogical insights for integrating multimodal reading and writing practices in higher education EFL classrooms.

Abstract

Local wisdom in Indonesia is a valuable cultural heritage. To preserve it, it can be introduced through school education, one of which is in physics education. Several researchers have studied local wisdom-based physics education in traditional games in depth, but no specific focus on the Egrang game has been found. Therefore, this study aims to analyze and identify the physics concepts found in the traditional game of stilts as an effort to integrate local wisdom into physics education. The research method used is a Systematic Literature Review (SLR) using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) design. Data was obtained from the Google Scholar database using the keyword “traditional Egrang game.” From the 1,270 documents identified, after screening based on inclusion and exclusion criteria, 7 articles were obtained that were suitable for analysis. The data was then analyzed descriptively to identify and classify physics concepts in the traditional Egrang game. The results of this study indicate that stilts are related to the physics concepts of work and energy, namely, mechanical energy consisting of kinetic and potential energy. Identification from the literature review also found other concepts such as rigid body equilibrium, balance, weight, and gravitational force. The results of this study confirm that stilts can strengthen students' understanding of physics concepts and the development of teaching materials in physics learning.

Abstract

This study investigated the effectiveness of Mobile-Assisted Language Learning (MALL) in enhancing students’ writing skills through the use of the CAKAP and Busuu applications. The objectives of the study were to examine the effect of the CAKAP application on students’ writing skills, to determine the effect of the Busuu application on students’ writing skills, and to identify which application provides a more significant improvement in students’ writing performance. The study employed a quantitative research design using a quasi-experimental method involving three classes: Experimental Class I (CAKAP), Experimental Class II (Busuu), and a control class receiving conventional instruction. Pre-tests and post-tests were administered to measure students’ writing ability before and after the treatment. The data were collected through writing tests and analyzed using a t-test. The findings revealed that students’ writing ability before the treatment was relatively low in both experimental groups. After the implementation of the applications, students in both experimental classes showed significant improvement in their writing performance. The t-test results indicated that the t-value for the CAKAP group (11.611) was higher than the t-table value (1.68657) at the significance level of 0.05 with a degree of freedom of 35. Similarly, the Busuu group showed a t-value of 11.501, which was also higher than the t-table value. These results indicate that both applications significantly improved students’ writing skills. However, the CAKAP application demonstrated a slightly higher effect compared to the Busuu application. Therefore, the alternative hypothesis was accepted, and the null hypothesis was rejected. The study suggests that mobile-assisted language learning applications such as CAKAP and Busuu can serve as effective tools for improving students’ writing skills in English language learning contexts.
