Abstract

The Indian Ocean region south of Java constitutes a highly active seismic zone dominated by the subduction of the Indo-Australian plate beneath the Eurasian plate. This study investigates the seismicity parameters (a-value and b-value) using the Gutenberg-Richter law and estimates the return periods of significant earthquakes. Analyzing earthquake catalog data covering a span of 53 years, we identified the Magnitude of Completeness (Mc) and calculated frequency-magnitude distributions. The results reveal a b-value of 1.17, indicating a region characterized by high material heterogeneity and complex stress release mechanisms. Furthermore, the probabilistic return period for a magnitude 6.5 earthquake is estimated to be approximately 19.24 years. These findings suggest that while the region exhibits frequent moderate-magnitude energy release, the potential for destructive tsunamigenic events remains significant, necessitating robust hazard mitigation strategies for the southern coast of Java.

Abstract

Entrepreneurship-based education in the era of globalization and fast-developing technology is becoming increasingly important for the younger generation to face the challenges of a dynamic world of work. The purpose of this study is to explore the effectiveness of entrepreneurship education in shaping an innovative mindset among students. The methods used in this study include qualitative analysis through a literature review approach to analyze and summarize various relevant sources on entrepreneurship education and the development of creative and innovative thinking skills in students. The results showed that entrepreneurship-based education successfully improved students' skills in identifying opportunities, solving problems creatively, and adapting to change. The implication of this study confirms that the integration of entrepreneurship education in the curriculum can significantly contribute to the development of relevant skills for students, as well as encourage innovation and economic growth in society. Further research is recommended to explore different approaches in teaching entrepreneurship and their impact on students' long-term development.
