Abstract

In today's global era, archive management plays a crucial role in supporting operational efficiency and informed decision-making. The adoption of cloud computing offers an innovative solution for managing digital archives more effectively and efficiently. This journal discusses the implementation of cloud computing in digital archive management using MySQL as a relational database management system. Through this approach, archive data can be stored, accessed, and managed more securely while ensuring data integrity. The study also explores the advantages of MySQL in terms of performance, scalability, and ease of access. Implementation of this system in several organizations has shown significant improvements in archive management efficiency and a reduction in operational costs. This system helps organizations manage their digitized data effectively by utilizing cloud computing as a more affordable and reliable storage solution

Abstract

A Decision Support System (DSS) is a computer-based system that generates various decision alternatives to assist management in addressing both structured and unstructured problems using data and models. DSS can also be applied to determine recipients of Direct Cash Assistance (BLT), such as in Meunasah Alue Village. This system is expected to assist the village authorities in selecting BLT recipients more efficiently and effectively each year. The method used in this system is Simple Additive Weighting (SAW), which considers predefined criteria and applies weighted scoring. The aim of this research is to determine suitable BLT recipients in Meunasah Alue Village by using DSS to support accurate and fair decision-making. The results of this study show the top three candidates: Armiati with a score of 227.75, Muliadi with a score of 225.5, and Maimunah with a score of 181.5.

Abstract

This study examines the clustering of crime incident data across Indonesia from 2000 to 2024 using the Fuzzy C-Means (FCM) algorithm, with a focus on the impact of data normalization. Comprehensive annual provincial crime statistics from Badan Pusat Statistik (BPS) were preprocessed to handle missing values and then standardized via the Standard Scaler. FCM clustering was performed separately on both the original and normalized datasets, with the number of clusters set to three. Cluster quality was evaluated over ten independent runs using five metrics: Davies-Bouldin Index (DBI), Silhouette Score (SS), Calinski-Harabasz Index (CH), Adjusted Rand Index (ARI), and Normalized Mutual Information (NMI). Results indicate that normalization consistently yields lower DBI values (average 0.824 vs. 0.830) and higher SS (average 0.367 vs. 0.363) and CH scores (average 55.35 vs. 54.09), while ARI and NMI remain stable across treatments. These findings demonstrate that normalization enhances cluster compactness and separation without altering underlying data structures, leading to more interpretable and reliable groupings. By uncovering regional crime patterns and highlighting the methodological importance of preprocessing, this research provides actionable insights for policymakers and law enforcement agencies to allocate resources more effectively and develop targeted crime prevention strategies.

Abstract

Learning basically aims to foster student activity and creativity through various learning experiences and interactions. Teachers are an important part of the process of improving the quality of education. In addition, the success of the learning process depends on student activity. The world of education needs to improve the quality of students and their performance by using existing facilities, infrastructure and human resources. One way information systems can be used to improve student achievement and quality is by analyzing grades based on students' academic abilities, discipline and way of behaving.The aim of this research is to group students based on academic scores, disciplinary scores and attitude scores using the K-Means Clustering algorithm, so that the cluster results can be used as a reference in improving student scores in the next learning process. In this research, the elbow method was used to determine the optimal number of clusters. Students will be grouped into clusters. Visualization and correlation analysis between value variables is carried out to provide further insight into the distribution of data and the relationship between its values.

Abstract

For most people, learning more about the many types of birds is difficult because there are so many species and many of them look similar in terms of size, color, and shape. Identifying bird species is not an easy task since it requires special skills, time, and money to study each type. Therefore, this study aims to develop an image processing system to classify bird species, especially birds found in the Aceh region. The system uses a combination of the K-Nearest Neighbor (K-NN) algorithm and Principal Component Analysis (PCA). Feature extraction in this study is based on the color and shape of the birds. The K-NN algorithm groups objects by finding the closest distance between them. Meanwhile, PCA is used to reduce the size of the data while keeping most of the important information. Based on the test results, the system achieved an accuracy of 82.50%, a precision of 83.06%, and a recall of 82.50%. This shows that combining K-NN and PCA in classifying bird images can produce better accuracy than using only the K-NN algorithm.Bird Species
