Abstract

Endophytic fungi are fungi that live and associate in host plants and have the potential to produce secondary metabolites that are the same as their host. Utilization of endophytic fungi as a solution reduces the use of a lot of biomass to produce the desired secondary metabolites. This study aims to explore and identify endophytic fungi found on lime leaves obtained from Kalpataru plantation, Denpasar, Bali. Endophytic fungi were isolated from samples of young and mature leaves that were fresh, not wilted or yellow, and disease free. Fungal isolation was carried out by direct planting method on Potato Dextrose Agar (PDA) media at room temperature (27oC), and the incubation time was 3-7 days. Re-isolation was carried out to obtain pure cultures, then the endophytic fungi were identified by observing the morphological characters macroscopically and microscopically, then compared with identification books. The results obtained were eight isolates, and six isolates were identified belonging to the genera Fusarium, Colletotrichum, Aspergillus, Penicillium, and 2 isolates were not identified (sterile mycelia). Endophytic fungi found on young leaves, namely Aspergillus and Colletotrichum, on mature leaves, namely Fusarium, Aspergillus, and Penicillium. Keywords: endophytic fungi, lime, sterile mycelia, PDA

Abstract

Physiological conditions are normal body functions in humans that undergo adaptation and refer to physical changes, especially in probandus who are migrating in a new environment. Students who migrate often experience various physiological condition challenges, such as changes in the amount of hemoglobin levels, blood pressure, and body weight. This study aims to determine the physiological conditions between male and female students who migrate from Java in the first year of study at the Faculty of Mathematics and Natural Sciences, Udayana University. The method of data collection was carried out in a qualitative way, namely interviews and quantitative ways, namely hemoglobin level tests, blood pressure tests, and weight measurements taken through male and female probandus. The results showed that hemoglobin levels in female probandus in the first year of college increased significantly compared to male probandus, which showed that female probandus were more able to adapt to the new environment. Blood pressure checks during the fasting month did not show significant changes in both female and male probandus, due to changes in diet during fasting that affect metabolism. Body weight before and after migrating also did not experience significant changes, which indicates changes in diet, physical activity and the adaptation of body metabolism as well as balanced calorie intake are factors that influence body weight. Keywords: psychological condition, overseas student, udayana university.
