Abstract

This study aimed to identify the variation of trichomes in the Solanaceae family found in the Cendana Hill of Sedan District, Rembang Regency. This study used the trichome printing method and the results were observed under a microscope. This study found trichomes glandular and non-glandular from the six Solanaceae species with various types. Different variations were found from the six species of the Solanaceae family, i.e: stellata, acicular, uncinate, hydathode, simplex and curved. The variations of trichomes from the Solanaceae family have different characteristics and shapes. This study identified six species from the Solanaceae family that have variations in the shape and type of trichomes on the epidermal layer of leaves, i.e: Solanum melongena var. melongena, var. serpentinum, Solanum lycopersicum, Solanum nigrum, Physalis angulata, Nicotiana tabacum, and Capsicum frutescens. Non-glandular trichomes act as a mechanical defense against pathogens and herbivores, while glandular trichomes have the function of secreting secondary metabolites, such as alkaloids and flavonoids, which play a role in chemical defense.

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
