Abstract

This study aims to analyze the growth trend of covid-19 using prediction algorithms in data mining for covid-19 data throughout Indonesia. This can be used as a decision support to analyze several government policies towards regulatory intervention so far. The method used is the best prediction method in time series data, including Neural Network, SVM, Linear Regression, K-Neirest Neighborn and optimizes it with optimization algorithms. This research is focused on the application of these applications. It is hoped that this research will produce an analysis of the growth trend of Covid cases every day, in addition to its contribution so that it can assist the government in determining the best policy direction and also as an education to the public. in addition, the research will contribute to science in the field of predictive analysis by finding the best RMSE formulation. The results of this study show that Neural Network-Particle Swarm Optimization has the smallest Roort Mean Square Error which is 265,326, and the two Neural Network Genetic Algorithm are 266.801, Neural Network Forward Selection is 275,372 and Neural Network without optimization has the largest RMSE which is 297.204. These results can be used as a reference for the use of similar algorithms in time series data, both Covid-19 data and other data.

Abstract

This study constructs an algorithm for rainbow vertex coloring in tree graphs. A graph G is defined as a set pair G=(V,E), where V is the vertex set and E is the edge set. Rainbow dot coloring aims to assign a color to each vertex of a tree graph T, such that each path in the tree has vertices with unique colors. The rainbow dot coloring algorithm developed in this study is implemented in a programming language, and its performance is evaluated through simulations on various types of tree graphs. The results show that this algorithm can effectively color tree graphs with good optimality. This research contributes to graph coloring theory and its potential to be applied to computational problems involving tree graphs with complex structures.

Abstract

Telur ayam merupakan salah satu bahan pangan yang banyak digemari oleh masyarakat dan memiliki kandungan nutrisi yang sangat dibutuhkan tubuh. Kualitas telur sangat dipengaruhi oleh faktor internal dan eksternal, yang dapat memengaruhi kesegarannya. Penurunan kualitas telur sering disebabkan oleh kerusakan fisik, kontaminasi mikroba, serta kondisi penyimpanan yang tidak tepat. Salah satu bentuk kerusakan yang umum adalah keretakan pada kerabang telur, yang dapat membuka celah bagi masuknya bakteri berbahaya seperti Salmonella. Oleh karena itu, penting untuk melakukan identifikasi kualitas telur secara akurat, terutama untuk mencegah kerugian ekonomi pada peternak dan menjaga kesehatan konsumen. Salah satu metode yang efektif untuk mengidentifikasi kualitas telur adalah dengan menggunakan teknologi pengolahan citra digital, khususnya melalui penerapan Convolutional Neural Network (CNN). Penelitian ini bertujuan untuk mengembangkan dan menerapkan metode CNN dalam mengklasifikasikan kualitas telur ayam berdasarkan kondisi kerabangnya. Dengan menggunakan citra digital yang diambil melalui kamera handphone, diharapkan penelitian ini dapat memberikan solusi praktis dalam klasifikasi kualitas telur, baik untuk konsumsi maupun distribusi di pasar. Hasil yang diharapkan dari penelitian ini adalah tercapainya tingkat akurasi yang tinggi dalam identifikasi kualitas telur, yang dapat mempermudah proses seleksi telur oleh peternak dan konsumen.

Abstract

This research was conducted with the aim of developing the Repository application, initially the system was more directed to journal searches, did not provide reading access rights, no journal download feature and the information was still incomplete so that it would be developed using Android-based technology. Through this research, it is hoped that the journal search process wil be much more this application was developed using the SDLC system development method or Software Development Life Cycle which has several stage, namely Planning, Analysis, Design and Implementation. By using system testing Black-box type Boundry Value Analysis/Limit Testing. The result of this research are in the form of an Android-based library repository application software.

Abstract

This study aims to overcome this issue by objectively determining the best positions of the soccer players through the application of the Profile Matching technique. The process consists of five steps: GAP values are first determined by comparing each player's unique traits to predetermined benchmarks. Next, compute the primary and secondary standards, establish weighted scores by utilizing the GAP values, compute the GAP values by contrasting specific player attributes with predetermined benchmarks, compute the overall scores, and order players according to their performance. A weighted combination of mental, physical, and skill criteria (30, 40%, and 30%, respectively) determines the final positions. The results demonstrate how effectively this rigorous technique scores the participants. This process offers a logical and objective approach to player selection, enhancing the precision and effectiveness of decision-making in soccer team management.

Abstract

Infants and toddlers are in a critical period of rapid growth and development, often referred to as the "golden age." During this stage, regular nutritional assessments are essential to monitor health status and detect potential nutritional problems early. This study aims to classify the nutritional status of infants and toddlers using the Naïve Bayes algorithm, a probabilistic classification method based on Bayes' theorem with a strong assumption of attribute independence. The main attributes used in the classification system include age, weight, and height. The dataset consists of 700 records of infants and toddlers collected from previous observations. The results show that the Naïve Bayes algorithm can be effectively implemented for nutritional status classification, achieving a system accuracy of 88.14%. This indicates that the method performs well and has the potential to be utilized in decision support systems for child health monitoring.
