Abstract

Genomic analysis has become a major focus in cancer research to identify biomarkers that are important for more precise diagnosis and therapy. However, a major challenge in genomic analysis is the complexity and high dimensionality of genomic data, which requires sophisticated analysis approaches. This study aims to develop a deep learning model based on Convolutional Neural Networks (CNNs) that can recognize cancer biomarker patterns from genomic data with high accuracy. Relevant genomic data were collected and processed, then used to train CNNs models using optimization and regularization techniques. The CNNs model was then evaluated using validation data to measure its performance. The evaluation results show that although the model has improved in reducing the loss value, the accuracy obtained is still not optimal. The model is not fully able to identify cancer biomarker patterns accurately from the available genomic data. This research provides an important foundation for further development in genomic data analysis using deep learning. Suggestions for further research include the use of more representative data, optimization of model architecture, data augmentation, regularization, and external validation to improve model performance in cancer biomarker identification.

Abstract

Proper bread inventory management is very important to avoid shortages or waste of stock at Coffeebox, which has been experiencing problems in estimating inventory needs due to manual data management. This study aims to develop a bread inventory requirement estimation model using the multiple linear regression method with bread ordering and bread sold variables. The data used consists of 29 observation samples which are processed through regression calculations to obtain regression coefficients and linear equations. The results showed that the resulting model has the formula Y = 3.152506333 + 0.03249542 X₁ + 0.012684868 X₂, with an estimated bread inventory requirement of 107 boxes based on daily demand and sales data. The implication of these findings is that multiple linear regression models can be used to optimize stock management and improve operational efficiency at Coffeebox. This study has limitations in terms of the variables used, so future research is recommended to expand the model by considering other external variables or using more complex methods such as machine learning algorithms to improve prediction accuracy.

Abstract

To ease the burden of student tuition fees, AMIK Medicom provides a scholarship program. However, in the process of determining students who are entitled to receive scholarships, the institution experiences problems due to the large number of applicants, so that the selection process becomes ineffective and takes a long time. This research uses the Simple Additive Weighting (SAW) method as a solution to help the decision-making process. The SAW method was chosen because it is able to determine the best alternative from a number of candidates based on certain criteria, namely parents' income, number of children, number of dependents, place of residence, and academic grades. The results of the research show that this system is able to objectively rank students, making it easier for institutions to determine scholarship recipients more accurately and efficiently.
