Abstract

The low participation of vocational high school graduates in higher education (10% nationally) is a challenge. This study examines the correlation between academic achievement and interest in continuing education among students at SMKN 1 Batusangkar. This quantitative correlational study involved 33 12th-grade students in the Culinary Services Expertise Program. Data were collected via a Google Form questionnaire (Likert scale 1-5, Cronbach's α = 0.85) and report card grades from the odd semester of 2023/2024. Analysis used Pearson Product-Moment correlation with SPSS. The results show a robust correlation between academic achievement and interest in continuing education (r = 0.99, p < 0.001). Students with high grades tend to be interested in college. Academic achievement can predict interest in continuing education with 99.6% accuracy. The findings encourage vocational high schools to prioritize improving academic achievement to boost interest in college, for example, through the implementation of mentoring programs.

Abstract

Environmentally friendly synthesis of barium titanate (BaTiO3) nanoparticles was conducted using natural leaf extracts of Moringa oleifera, Musa spp., Pometia pinnata, and Terminalia catappa as green dopants via the sol-gel method. This study aims to evaluate the influence of different leaf extracts on the optical properties of BaTiO3 characterized by UV-Vis spectroscopy. Each sample exhibited distinct absorption spectra, reflecting variations in phytochemical composition among the extracts. The results showed that Terminalia catappa and Pometia pinnata extracts produced the highest band gap values, 3.36 eV and 3.35 eV respectively, indicating optical activity in the ultraviolet region. Musa spp. extract resulted in a band gap of 2.81 eV, while Moringa oleifera extract yielded the lowest value of 2.59 eV. These differences suggest that the type of plant extract significantly affects the optical characteristics of the synthesized BaTiO3. This research highlights the potential use of local biomass in the development of functional BaTiO3-based materials through green synthesis approaches.
