Abstract

This study aims to observe the process of vegetation succession in the Campus Park area, Old Building STAIN Mandailing Natal, Faculty of Tarbiyah, and Keguruan Science, focusing on changes in vegetation types that occur during observation and factors that influence the course of succession. The research was conducted using a quantitative observation method, in which data were collected through field surveys by laying plots in parallel. Data collected included species type, dominance analysis, density measurement, relative density, and plant frequency. The results showed that Asystasia gangetica was the dominant species during the secondary succession stage, due to its high ability to colonize and adapt to disturbed environmental conditions. Besides Asystasia gangetica, other species found include Digitaria sanguinalis, Meryta latifolia, Curculigo capitulaca, Anthurium crystallinum, and Clitoria ternatea. The dominance of Asystasia gangetica is influenced by post-cultivation soil conditions, competition between species, and its ability to adapt. Climatic factors also play an important role in influencing the succession process. The practical implications of the results of this study are recommendations for increasing vegetation diversity and vegetation monitoring in the context of secondary succession.

Abstract

This study aims to explore biology education students' perceptions of integrating entrepreneurship education with courses, interest in entrepreneurship, and self-efficacy. This study is an exploratory descriptive research, the respondents were 77 biology education students at UIN SYAHADA Padangsidimpuan. The instrument used was a closed questionnaire with the Guttman scale. Research data was analyzed descriptively and inferential statistics using the Kruskal Wallis test. The results of the study are: 1) student perceptions regarding the integration of entrepreneurship education are very positive, as many as 83.1% of students feel that integration needs to be implemented. Based on the Sig value (0.86 0.05), there is no significant difference between the perceptions of semester III, V, and VII students; 2) Students' entrepreneurial interest is relatively high, namely 77.9% of students are interested in entrepreneurship. Based on the Sig value (0.43 0.05), there is no significant difference between the interests of semester III, V and VII students; 3) Student self-efficacy in entrepreneurship is classified as moderate, namely only 50.6% of students believe in their abilities. Based on the Sig value (0.07 0.05), there is a significant difference between the self-efficacy of students in semesters III, V, and VII.
