Abstract

Autophagy is a cellular mechanism in the form of degradation and recycling of intracellular components that plays an important role in maintaining cell homeostasis, especially when cells are under stress conditions such as nutritional limitations, oxidative stress, organelle damage, or pathogen attacks. Through this process, cells are able to survive by eliminating damaged or dysfunctional structures, while simultaneously reusing the degradation products as a source of energy and building blocks for new molecules. This study aims to examine the mechanism of autophagy, the molecular regulations involved, and its role in the response to various forms of cellular stress using a literature review method. Reference sources in this study come from relevant scientific articles and are accessed through PubMed, Scopus, and Google Scholar databases with a publication year range of 2015-2024. Articles are selected based on the main inclusion criteria, namely discussions on the molecular pathway of autophagy, the process of autophagosome formation, and the role of lysosomes in cellular degradation mechanisms. The study results indicate that autophagy is an essential adaptive mechanism primarily controlled by the mTOR and AMPK pathways in response to cellular stress. Adaptive autophagy plays a crucial role in maintaining cell stability and survival, while autophagy dysfunction or uncontrolled activation is pathological and contributes to the development of various diseases, making autophagy a strategic therapeutic target. Furthermore, disruption of the autophagy process is known to be closely associated with the development of various degenerative and metabolic diseases, making autophagy a potential target in the development of biomedical therapeutic strategies.

Abstract

This research is motivated by the low learning outcomes of students due to learning strategies that tend to be one-way and less actively involve students. This study aims to determine the application of Student Worksheets (LKPD) based on concept maps on student learning outcomes on environmental pollution material in class VII of SMPN 1 Ende. This study uses a quantitative method with a true experimental design in the form of a randomized control group pretest-posttest design. The research subjects were 70 students consisting of 35 students in the experimental class and 35 students in the control class. The results showed that the average value of student learning outcomes in the experimental class increased significantly from 49.28 in the pre-test to 97 in the post-test, with an increase of 96.85%. While in the control class, the average value of learning outcomes increased from 50.6 in the pre-test to 64.11 in the post-test, with an increase of 26.71%. The t-test results showed a significance value of 0.000 ≤ 0.05, indicating a significant difference in learning outcomes between the experimental and control classes. Thus, the implementation of concept map-based student worksheets (LKPD) has been proven effective in increasing student activity, engagement, and learning outcomes.

Abstract

Student perception is their view and assessment of the experience and learning process in the classroom. This is important to study because the success of a learning model is also determined by how students interpret and respond to its implementation. This study aims to determine student perceptions of the implementation of the Project Based Learning (PjBL) learning model based on experiments with scientific articles as products in lower-level botany courses. This study is a quantitative descriptive study with an ex post facto approach using a survey method. Sampling was carried out using a purposive sampling technique on students of the Biology Education Study Program, Faculty of Teacher Training and Education, Mulawarman University. The data analysis technique used descriptive statistical analysis. The results of the data analysis show that the average result of all observed aspects obtained a percentage value of 84.99% which is included in the "very good" category, so it can be concluded that students of the Biology Education Study Program have a positive perception of the implementation of the Project Based Learning (PjBL) learning model based on experiments with scientific articles as products in lower-level botany courses. Therefore, these findings emphasize that the implementation of this learning model is worthy of being maintained and further developed with improvements, particularly in technical aspects and structured academic mentoring to optimize the quality of the learning process and outcomes.
