Abstract

This study aims to determine the characteristics of project-based learning and discovery learning virtual media on animal classification material and test the effectiveness of project-based virtual media discovery learning on animal classification material on analytical thinking skills. This research is a mixed type of research. The research design used is the exploratory sequential design, using qualitative data analysis as the initial stage and then used as a direction to determine the formulation of research problems, samples, and quantitative data collection methods, followed by the development of virtual media instruments based on project-based learning and discovery learning. Quantitative methods are applied using quasi-experimental research. The study design used a nonrandomized control group and a pretest-posttest design. The treatment class uses PjBL-based virtual media Iimplementation, the control class uses a virtual media discovery model-based. The test instrument used is an essay question to measure analytical thinking skills adapted from Brookhart. Data analysis using ANCOVA (p = 0.05%) with prates as covariates. The result of the differences in the characteristics of project-based learning and discovery learning virtual media lies in the syntax of learning models, virtual activities, work produced, and attitudes developed. The feasibility test results of both virtual media were declared suitable for use. The results of ANCOVA showed that project-based virtual media learning is more effective in improving analytical thinking skills than discovery-based virtual media learning.

Abstract

Earlier research reported that GABA had a correlation with diabetes in processes of glucose homeostasis. This study aims to identify the validity of B-receptor Rattus norvegicus as GABA protein target, modeling the structure and knowing the binding affinity between GABA and B-receptor Rattus norvegicus through molecular docking.   The research was carried out using in-silico method.  The interaction of GABA with the target protein was determined using SuperPred, followed by modeling the protein target using SwissadMe. Ramachandran Plot and Errat Procheck are used to determine the validity of the protein target. Molecular docking was determined using Pyrx and PyMol. The results showed that GABA binding to the B- receptor Rattus norvegicus has biological activity as glucose oxidase inhibitor and antidiabetic.  The conclusion are: B-receptor Rattus norvegicus is a valid protein target for binding to GABA; there are four 3-dimensional models of B-receptor Rattus norvegicus and the best model has 98.43% sequence identity; the binding affinity of GABA (ligand) on B-receptor Rattus norvegicus from the best model is -3.4 kcal/mol energy, 1.773 RMSD lower bound, and 1.81 RMSD upper bound. It is suggested that this research might be used as an empirical basis to further investigate GABA as antidiabetic.
