Abstract

This community service project responds to the growing need to enhance teachers’ digital competence amid the rapid expansion of the digital economy, particularly in e-commerce. Implemented at SMK Negeri 1 Woyla, the program involved 14 teachers and adopted a participatory training approach, including pre-test, interactive sessions, discussions, hands-on practice, and post-test evaluation. The training focused on e-commerce concepts, marketplace utilization, and digital marketing practices. Initial results indicated that participants had a moderate level of theoretical understanding but limited practical experience, especially in using marketplace platforms. Following the training, there was a clear improvement in both knowledge and practical skills, reflected in the successful creation of marketplace accounts and increased confidence in applying digital tools. Overall, the program effectively strengthened teachers’ digital competencies and supported the integration of e-commerce into vocational learning.

Abstract

One of the biggest exporters of canned tuna worldwide is Indonesia. The purpose of this research is to examine the market dynamics and competitiveness of Indonesia's canned tuna exports (HS 160414) to important export markets between 2020 and 2024. This study uses a quantitative descriptive method with four analytical tools, which are Revealed Comparative Advantage (RCA), Revealed Symmetric Comparative Advantage (RSCA) Export Product Dynamics (EPD), and the X-Model Potential Export Product. Data were sourced from Trademap and the World Integrated Trade Solution (WITS). The results indicate that Indonesian canned tuna possesses a strong comparative advantage in nearly all destination countries, with RCA values >1 and positive RSCA values. Ecuador recorded the highest RCA value, while Egypt and Malaysia consistently lacked a comparative advantage. The EPD analysis placed South Korea, Oman, and Thailand in the Rising Star category as markets with the greatest potential. Based on the X-Model analysis, these three countries fall into the Optimistic Market Development category and are the top priorities for the development of Indonesian canned tuna exports. This study recommends strengthening market penetration strategies in high-potential countries as well as improving the quality and sustainability of fisheries resource management as the key to long-term competitiveness.

Abstract

This study conducts a focused systematic literature review of 15 empirically rigorous studies published between 2020 and 2025, selected from an initial pool of 65 candidate articles identified through a Scopus database search. Selection prioritized studies that explicitly reported effect sizes, employed structural equation modeling or experimental design, and examined purchase intention as a primary outcome variable. Guided by three research questions, RQ1: what influencer attributes are empirically associated with consumer purchase intention and with what relative strength? RQ2: what psychological mechanisms mediate the relationship between influencer attributes and purchase intention? RQ3: what contextual factors moderate the effectiveness of social media influencers on purchase intention? The review applies the Stimulus-Organism-Response (S-O-R) framework as a unifying theoretical architecture. Trustworthiness emerges as the most consistent predictor (RQ1), information credibility, utilitarian value, and parasocial relationships mediate effects (RQ2), and product category, generational cohort, and influencer type moderate outcomes (RQ3). Research gaps include cross-cultural comparisons, longitudinal designs, and over-endorsement saturation thresholds.
