Abstract

Coconut is a plantation commodity in Padang Pariaman Regency that has experienced an increase in production during 2023. The waste from coconut shells can be further processed into a product with high economic value and even reach the export market, namely coconut charcoal briquettes. The purpose of this activity is to provide knowledge and skills about production, promotion, marketing, and financial management to the partners. The method used is community development through lectures, discussions, Q&A sessions, practical activities, and mentoring. The partners for this activity are the Sukses Bersama and Maju Makmur Business Groups, with 15 participants. The evaluation results show that 100% of the participants gave positive responses and answers to all questions asked about the training activities. The outcome of this service is significant for the participants to improve the quality of the briquette products, as well as marketing and financial management.

Abstract

Academic underachievement in Indonesian vocational high schools (SMK) is often attributed to cognitive ability alone, yet non-cognitive factors may matter. Drawing on Bandura's social cognitive theory and Astin's involvement theory, this study tested whether student engagement mediates the associations of self-efficacy and learning motivation with examination performance. A cross-sectional survey was administered to 282 students in four state vocational high schools in Pesisir Selatan Regency, West Sumatra, sampled proportionately by school. Constructs were modelled as reflective-reflective higher-order constructs and estimated with the disjoint two-stage approach in PLS-SEM; performance was a single summative examination score drawn from school records and not equated across the four schools. After item purification the engagement construct retained only its behavioural and emotional dimensions, so H5 to H7 test a narrower construct than the introduction describes. Discriminant validity was not established for the self-efficacy and engagement pair (HTMT = .908, above the pre-specified .90). Self-efficacy (β = .640, 95% CI [.537, .743]) and learning motivation (β = .141, 95% CI [.027, .255]) were associated with engagement, explaining 55.7% of its variance. No path reached examination performance: the model explained essentially none of its variance (R² = .005, adjusted R² = -.006), and all three paths were statistically equivalent to zero within ±.20. Five hypotheses were not supported. The null result is consistent with criterion misalignment, but the design did not test that explanation.
