Abstract

Collaboration skills are one of the 21st-century skills that are very important for students, especially in facing the challenges of the complex world of work and social life. Students' collaboration skills in the Biology Education Study Program at Universitas Sembilanbelas November (USN), Kolaka, are still relatively low. One approach believed to improve students' collaboration skills is the application of Project-Based Learning (PjBL). Thus, this study aims to determine the effect of the application of Project-Based Learning on the collaboration skills of students in the Biology Education Study Program at USN Kolaka. This study is a pre-experimental type using a one-group pretest-posttest design. The subjects of the study were all active students (16 people) of the biology education study program, even the semester of the 2024/2025 academic year, who took the course "Media dan Sumber Pembelajaran Biologi". Data on students' collaboration skills were obtained using a collaboration skill observation sheet. Data analysis used an inferential test of the paired sample t-test type. The results of the study showed that the average collaboration skill of students before treatment was 30.77, and during treatment was 83.64. From the results of the inferential test, the Sig. The value was obtained. 0.000 0.05. This study concludes that there is a positive effect of the implementation of PjBL on students' collaboration skills. These findings indicate that PjBL can create a learning environment that encourages active participation, shared responsibility, effective communication, and constructive teamwork. Therefore, PjBL can be a strategic alternative for improving students' collaborative soft skills sustainably in higher education environments. Keywords:  collaboration, project-based learning

Abstract

This literature review explores the multifaceted role of Pseudomonas syringae, a bacterium renowned for its ice-nucleating properties. Pseudomonas syringae significantly influences atmospheric processes, agriculture, and various ecosystems. These bacteria, equipped with ice nucleation proteins (INPs), facilitate ice formation at temperatures warmer than the typical freezing point, impacting weather patterns by initiating snow and hail formation. While its ice-nucleating activity can lead to frost damage in agriculture, it is also harnessed for artificial snow production. This review synthesizes findings on the bacterium's characteristics, morphology, physiology, and ecology, drawing from diverse studies. It highlights its widespread presence in various environments, including plant surfaces, water bodies, and atmospheric samples, emphasizing its adaptability and ecological significance. By employing content analysis on secondary data sources, this study provides a comprehensive understanding of Pseudomonas syringae's unique ability to mediate ice formation and its broader implications for environmental balance and biotechnological applications.Keywords:  INA bacteria, Pseudomonas syringae, ice formation, InaZ  protein

Abstract

Education is the key to progress and quality development because humans can realize their full potential with education. One of the courses that discusses theory is the education profession course, which examines the concept of professional teachers. This study aims to determine the role of education profession courses in improving the character values of students as prospective biology teachers. This study uses a qualitative descriptive method. Data was collected by distributing research questionnaires containing statements about the study's title. The research sample included biology education students in 2020, 2021, 2022, and 2023 intakes, with 45 students as respondents. This study concludes that education profession courses are essential in improving students' character values. In addition, lecturers in charge of the course are also very important in guiding and being an example for students as prospective biology teachers.Keywords:  character values, students, teachers, biology

Abstract

There are several main indicators that can be used to assess the quality of sourdough starter, namely pH, dough volume, and the presence and diversity of Lactic Acid Bacteria (LAB). Meanwhile, the addition of natural ingredients such as fermented Ambon bananas is considered to be able to improve the quality of sourdough starters, by increasing the number and diversity of LAB. This study is a comparative exploratory study that compares the quality of sourdough starters made with fermented Ambon bananas (Type III) and those made without Ambon bananas (Type I), and identifies the diversity of LAB in both. This study showed that all parameters are better in type III than in type I, where the pH is lower, the dough develops faster and has a larger volume, and the number of LAB is higher. Meanwhile, the LAB contained in Type III is more diverse (Lactobacillus pentosus, Lactobacillus plantarum, and Lactobacillus paraplantarum) compared to Type I, which only contains one isolate (Lactobacillus pentosus). Based on the results found, sourdough with the addition of Ambon banana fermentation can produce better starter quality and contains more diverse LAB, namely heterofermentative and homofermentative.Keywords: sourdough starter, fermented ambon banana fruit, lactic acid bacteria.

Abstract

Learning at SMAN 1 Wundulako remains centered on lectures and textbooks. Although media such as PowerPoint and Canva have been used, their utilization has not been optimal. As a result, students tend to be passive and show low learning interest. Therefore, there is a need for innovative learning models and interactive media to enhance students' interest in learning. This study aims to examine the effect of implementing Project-Based Learning assisted by Kahoot media on students’ learning interest in biology. The research employed a quantitative approach with a quasi-experimental method. The research design used was a posttest-only control group design. Instruments used to measure students' learning interest included questionnaires and interview sheets. Data were analyzed using a parametric test, namely the independent sample t-test, at a significance level of 0.05. The results of the hypothesis testing indicate a significant effect of Project-Based Learning assisted by Kahoot media on students’ learning interest in biology among Grade X students at SMAN 1 Wundulako. It can be concluded that the implementation of Project-Based Learning supported by Kahoot media can help improve students’ interest in learning biology in Grade X at SMAN 1 Wundulako.Keywords: Learning Interest, Project-Based Learning, Kahoot-Assisted Media
