Abstract

This study aims to analyze the patterns of fastfood consumption, nutritional status, and prevalence of anemia among female students in the Nutrition Department of Poltekkes Medan. An observational method with a cross-sectional design was used on 73 female students. Data on the frequency of fastFood consumption was collected using a semi-quantitative FFQ, nutritional status was assessed based on BMI, and hemoglobin levels were measured using the Cyanmethemoglobin method. The results showed that 45.20% of respondents frequently consumed fast food, with an obesity prevalence of 35.70% and anemia prevalence of 35.60%. There was a significant relationship between fast food consumption and nutritional status (p=0.042), but not with anemia status (p=0.540). In conclusion high fastfood consumption correlates with obesity and anemia. Efforts are needed to increase the availability of healthy food on campus and further research on the long-term impact of ast Food consumption on student health.

Abstract

Urban opinion from crowdsourced data often leads to imbalanced datasets due to the diversity of issues related to urban social, economic, and environmental topics. This study presents a novel hybrid approach that combines Random Over-Sampling and Random Forest (ROS-RF) to effectively classify such imbalanced data. Using crowdsourced urban opinion data from Jakarta, experimental results show that the ROS-RF method outperforms other approaches. The ROS-RF classifier achieved an impressive F1-score, recall, precision, and accuracy of 98%. These findings highlight the superior effectiveness of the ROS-RF method in classifying urban opinions, especially those related to social, economic, and environmental issues in urban settings. This hybrid approach provides a robust solution for managing imbalanced datasets, ensuring more accurate and reliable classification outcomes. The study underscores the potential of ROS-RF in enhancing urban data analysis and decision-making processes

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.
