Abstract

students for the dynamic global world. Research shows a positive relationship between entrepreneurship education, entrepreneurial activities, and entrepreneurial intentions of vocational students. The integration of entrepreneurship education in the vocational education system supports the national agenda to encourage innovative and entrepreneurial practices among youth. In this context, the development of entrepreneurial skills among SMK students is essential, including communication, collaboration, and digital skills. The 2019 National Standard for Vocational Education emphasizes the importance of entrepreneurship, character, and literacy competencies.   Business Model Canvas (BMC) training is a solution to help SMK students understand and plan their business comprehensively, improve their readiness to create jobs and overcome obstacles in starting a business. The study involved 30 students of SMKN 1 Gantiwarno, Klaten, and was organized at Universitas Muhammadiyah Surakarta using lecture, demonstration, and discussion methods. The result was an increase in students' knowledge, skills, and abilities in planning a business with BMC.   This activity successfully benefited the Perempuan Indonesia Maju community and the vocational school students. It is desired that students can apply the knowledge gained and it is recommended to organize follow-up training to deepen the material and understanding. Continuous evaluation will ensure the long-term impact of this community service.

Abstract

This study explores the potential of nanoscale silicon carbide (SiC) particles synthesized from rice husk ash to enhance light absorption characteristics in solar panel applications. The SiC particles were produced by burning rice husks, followed by purification and division into two groups: one group underwent heat treatment at 400 °C, while the other was kept untreated for comparative analysis. High-Energy Milling (HEM) for 60 hours was used to reduce the particle size of selected samples. Comprehensive characterization was performed using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and UV-Vis spectroscopy in the wavelength range of 200–1100 nm. The results of the study indicate that heat-treated SiC exhibits significantly reduced agglomeration and better particle dispersion compared to untreated samples. FTIR analysis confirmed the presence of additional functional groups (C=C and O–H) in the treated SiC, which contribute to surface chemical modification. Most importantly, the UV-Vis spectra show that the treated SiC maintains consistently higher absorbance values (0.5–0.6) in the visible to near-infrared region (400–1100 nm), whereas the untreated SiC exhibits a decreasing trend (0.4–0.2). These findings suggest that thermal processing can enhance the optical performance of SiC nanoparticles by improving dispersion and introducing functional groups that strengthen light-matter interactions. The superior absorption characteristics of the processed SiC demonstrate promising potential as an additive or nanostructured layer to improve photon capture and overall efficiency in photovoltaic devices
