Abstract

Numerical literacy is a fundamental skill that plays a crucial role in the learning process, particularly in the field of science, especially physics. However, the reality is that many freshmen struggle with numerical literacy. This significantly impacts their foundational mathematical skills, which can hinder the academic learning process. This community service activity aims to enhance the numerical literacy of freshmen in the Physics Department at the University of Lampung by utilizing interactive visual modules. The activity was conducted over two sessions in January 2025, involving 28 new students. The students were divided into heterogeneous groups to support collaborative learning. Pre-test and post-test assessments were conducted to measure the effectiveness of the modules. The results showed an average score improvement from 36.25% to 56.6%. Addionally, the satisfaction survey results showed positive responses regarding the module’s appearance, clarity and benefits. Based on this activity, it was concluded that collaborative learning supported by interactive visual media can enhance students numerical literacy skills.

Abstract

The manufacture of nanocellulose from red onion peel waste has been carried out using the acid hydrolysis method using H2SO4. This study aims to determine the effect of variations in the concentration of H2SO4 on the size of nanocellulose crystallites from onion peels and the surface morphology of nanocellulose from onion peels. The manufacture of nanocellulose was carried out in three stages, namely delignification using 10% NaOH to remove lignin and hemicellulose, bleaching using 10% H2O2 for bleaching and isolation of nanocellulose using H2SO4. The variation of H2SO4 used is 5; 10; 15 and 20%. The characterizations used are XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy). The results of XRD characterization showed that the crystalline phase contained at the highest diffraction peak and the optimum concentration of H2SO4 to make nanocellulose from onion peel was 20%. The results of SEM characterization showed that the morphology of the onion peel nanocellulose was still united to form bundles or agglomerates.

Abstract

ABSTRACTMaterial physics is an important branch of science that studies the properties and applications of various materials from atomic level as the foundation for modern technological development. The importance of this field encouraged the implementation of a socialization activity aimed at improving students’ understanding of the basic concepts and applications of material physics. The activity was attended by 22 participants and consisted of three stages: an initial survey, socialization using the one group pretest–posttest design through interactive and contextual methods, and data evaluation. The average pretest score of 2.22 increased to 3.45 in the posttest, indicating an improvement based on the Likert scale. These results show that the socialization activity contributed positively to enhancing participants’ understanding and interest in the concepts and applications of material physics. The interactive approach used in the socialization proved effective in strengthening participants’ motivation and insight into this field.Keywords: Physics, material, educationABSTRAKFisika material merupakan cabang ilmu penting yang mempelajari sifat dan aplikasi berbagai material dari tingkat atomik sebagai dasar pengembangan teknologi modern.

Abstract

Nanocellulose-based CNC–ZnO nanocomposites from garlic peel waste were successfully synthesized as environmentally friendly photocatalysts. This study aimed to valorize kitchen waste as a source of cellulose and combine it with ZnO through a one-pot precipitation method using CNC and Zn(NO₃)₂ as ZnO precursors. Structural, morphological, and optical properties were characterized using FTIR, XRD, SEM–EDX, XRF, and UV–Vis DRS. The XRD pattern showed a crystalline cellulose peak at 2θ ≈ 22.22° with a crystallite size of approximately 20.65 nm, while the CNC–ZnO nanocomposites showed crystallite sizes in the range of 23.93–31.12 nm. Peak shifts and broadening suggested interfacial interactions between CNC and ZnO, and the wurtzite ZnO reflections displayed a broad shoulder due to overlap with the cellulose peak and the high dispersion of ZnO within the CNC matrix. SEM–EDX analysis revealed a rod-like bundled agglomerated morphology, with the presence of Zn confirmed by EDX (39.23%) and XRF (~8.36%). The CNC–ZnO0.9 sample exhibited a band gap energy of 2.95 eV. Photocatalytic test against methyl orange (10 ppm) increased with UV irradiation time, achieving net photocatalytic efficiencies of 79.12% and 63% in the first and second cycles after 120 min, respectively. Kinetic analysis indicated that the degradation data were better described by a pseudo-second-order model with a rate constant of 0.0374 min⁻¹, indicating the role of surface interactions and the availability of active sites. These results confirmed the potential of CNC–ZnO nanocomposites derived from garlic peel waste as photocatalysts for organic dye degradation

This community service program aims to implement the Inverted Class method to evaluate its effectiveness in addressing this issue. The program activities were carried out in 3th dan 4th weeks of January 2025. This program was divided into three stages: preparation, classroom implementation, and evaluation of its success, involving 55 first-year physics students at Universitas Lampung. During the preparation phase, an interactive, engaging, and modern module was developed. An initial test was conducted to assess students' understanding of basic mathematical concepts, yielding an average score of 42.9%. The implementation phase involved two Inverted Class learning sessions. In the evaluation phase, the students' understanding improved significantly, with an average score increase to 60.5%. Additionally, students provided positive feedback on the learning process and the module used. This program successfully demonstrated that the Inverted Class method can serve as an effective approach to improving conceptual understanding while fostering students' independent learning skills. Keywords: inverted class; first-year students; physics; mathematical understanding; independence
