Abstract

The spot welding process using robotic systems is associated with a high risk of failure, including spot weld release, spatter, missed welds, unavailable weld spots, missing brackets, porous welds, double welds, incorrect weld positions, and sliding joint parts. This study aims to enhance risk assessment in spot welding by integrating fuzzy logic inference with Failure Mode and Effects Analysis (FMEA) to overcome the limitations of conventional FMEA in handling uncertainty and ambiguity. The proposed model incorporates fuzzy representations of severity, occurrence, and detection parameters to calculate the Fuzzy Risk Priority Number (FRPN) through three stages: fuzzification, fuzzy inference, and defuzzification. A case study was conducted in the spot welding process of automotive body components in Karawang, using real process data and expert validation. The results show that FRPN values range from 3.95 to 6.38, with the highest risks identified in spot weld release (FRPN = 6.38) and incorrect weld position (FRPN = 6.29), indicating that these failure modes are the top priorities for corrective actions. Furthermore, the fuzzy FMEA approach provides better discrimination of risk levels compared to conventional FMEA, particularly in differentiating failure modes with similar RPN values, thereby improving the accuracy and reliability of risk prioritization.

Abstract

This study examines the effect of social media use intensity and the quality of content received on self-confidence and its contribution to entrepreneurial intention in the higher education context. A quantitative research design was employed using a survey method, with a questionnaire distributed to 93 respondents selected through proportional random sampling. The study focuses on how social media exposure and the perceived quality of online content may shape students’ confidence in their ability to engage in entrepreneurial activities and develop entrepreneurial intention. The proposed model positions self-confidence as an important psychological factor that can strengthen the relationship between digital media exposure and entrepreneurial intention. The study is expected to provide insights for educators and academic institutions in designing learning support and digital literacy strategies that encourage students to use social media more productively for entrepreneurial development. It also emphasizes the importance of directing students not only toward understanding business concepts but also toward building confidence, initiative, and capability to start and sustain business activities.

Abstract

Unemployment remains a persistent challenge in developing economies, making entrepreneurship an increasingly important pathway for job creation, economic participation, and student career development. This study examines the direct and indirect effects of entrepreneurial knowledge and learning motivation on entrepreneurial intention, with entrepreneurial motivation positioned as a mediating variable. Using a quantitative explanatory design, data were collected from 152 students of the Faculty of Economics and Business, Universitas Sebelas Maret, through a structured questionnaire and analyzed using descriptive statistics and path analysis with SPSS version 26. The findings show that learning motivation and entrepreneurial motivation have positive and significant effects on entrepreneurial intention, while entrepreneurial knowledge has a positive but statistically non-significant direct effect on entrepreneurial intention. Entrepreneurial knowledge and learning motivation were also found to have positive effects on entrepreneurial motivation, which subsequently strengthens students’ entrepreneurial intention. These results indicate that entrepreneurial intention is not shaped solely by cognitive understanding of entrepreneurship, but also by students’ motivation to learn and their internal motivation to engage in entrepreneurial activity. The study highlights the importance of entrepreneurship education that integrates knowledge development, motivational support, and practice-oriented learning experiences to strengthen students’ readiness to pursue entrepreneurship as a career option.
