Abstract

The payment aggregator system with the single settlement feature enhances transaction efficiency. However, this also poses risks of cyberattacks and system errors. These risks can lead to abnormal events or anomalies. The middleware service records transaction activities in the form of logs. Log data can be analyzed for anomaly detection resulting from cyberattacks or system errors.K-Means clustering is less effective in detecting anomalies in log data because transaction log data is often unstructured, inconsistent, and has varying feature scales.This study develops a preprocessing algorithm to improve data quality before clustering. Transaction log data from July to December 2023 is used, with preprocessing stages including normalization, standardization, and Principal Component Analysis (PCA). K-Means is applied with K-Means++ initialization, and the number of clusters is determined using the kneedle algorithm. The results show that standardization improves segmentation, and PCA enhances anomaly detection effectiveness.

Abstract

This research is based on a statement from the Minister of Education, Culture, Research, and Technology, Nadiem Anwar Makarim, who said that Indonesian children are experiencing a crisis of self-confidence. Likewise, students of SDN 3 Dadap showed a lack of self-confidence, especially in grade IV, this impacts their Pancasila Education scores, where 19 out of 21 students scored below the KKM, or around 90% of students are below the KKM score standard. This is because the learning model teachers use still uses conventional learning models and lecture approaches. One of the solution steps taken is to replace the learning model currently used with the Role-Playing learning model. This study aims to determine the application of the Role-Playing learning model, to increase student learning outcomes in the Pancasila Education subject, and to increase the self-confidence of grade IV students of UPTD SDN 3 Dadap by implementing the Role-Playing learning model. The research model used is Classroom Action Research (CAR) with 3 cycles using the Kemmis and McTaggart design models consisting of four steps, namely: planning, implementation, observation, and reflection. This research was applied to 21 fourth-grade students. The learning outcomes of students obtained during the implementation of the action increased, as seen from the results of cycle III, as many as 18 students completed with an average score of 80 and a percentage of 85%. Likewise, the level of student confidence increased in each cycle. Based on the results of the study, shows that the role-playing learning model can improve the learning outcomes and self-confidence of elementary school students.

Abstract

Artificial Intelligence (AI) has significantly transformed the design industry by introducing innovative tools that enhance efficiency, creativity, and personalization in the design process. This article explores the impact of AI technologies on the practice of modern designers, from the early stages of idea generation to the final execution of projects. By analyzing case studies, conducting surveys, and reviewing recent literature, the study reveals that AI functions not only as a tool but also as a collaborator that expands the boundaries of human creativity. It allows designers to explore new possibilities and push the limits of traditional design processes. However, the integration of AI into design practices also raises important ethical and professional challenges, such as concerns about job displacement, data privacy, and the potential loss of human touch in the creative process. Despite these concerns, the findings highlight that embracing AI is crucial for designers to remain competitive and sustain their careers in the rapidly evolving digital era. Adapting to AI technologies, understanding their capabilities, and effectively incorporating them into creative workflows will enable designers to stay relevant and thrive in a landscape where technology continues to reshape the industry. This study provides insights into the evolving relationship between human designers and AI, offering recommendations for future research and practice in the field of design.

Abstract

Stock of goods not only determines the selling price of the product but also plays a major role in achieving the company's strategy in the future, especially in reaching the maturity stage and creating cost efficiencies. Companies must ensure that low inventory is managed through management accuracy to avoid large losses due to calculation errors. In addition to management accuracy, an information system is needed to be able to present data quickly and its accuracy is guaranteed for determining budgeting decisions and determining supplies in the supply chain that can be accounted for. To face this challenge, the author designed a supply chain management information system using the first in first out (FIFO) technique in the AHASS 2106 Waras Motor Workshop. This application will be created using PHP MySQL database to support employee performance in managing data. It is hoped that this system can provide fast and accurate inventory reports, as well as provide warnings when spare parts stock reaches the minimum limit, so that customers are not disappointed. System security is also ensured by the use of passwords, and a web-based database allows each user to work more effectively.   ABSTRAK Stok barang tidak hanya menentukan harga jual produk tetapi juga memainkan peran utama dalam mencapai strategis perusahaan di masa mendatang, terutama dalam mencapai tahap kematangan dan harus menciptakan efisiensi biaya. Perusahaan harus memastikan bahwa persediaan barang yang rendah dikelola melalui ketepatan manajemen untuk menghindari kerugian besar akibat kesalahan perhitungan. Selain ketepatan manajemen, sistem informasi diperlukan agar mampu menyajikan data dengan cepat yang dijamin ketepatannya, keakuratannya untuk penentuan keputusan penganggaran dan penentuan persediaan dalam rantai pasok (Supply Chain) yang bisa dipertanggungjawabkan. Untuk menghadapi tantangan ini, penulis merancang sistem informasi manajemen rantai pasok dengan teknik first in first out (FIFO) dalam Bengkel AHASS 2106 Waras Motor. Aplikasi ini akan dibuat memakai PHP basisdata MySQL untuk mendukung kinerja karyawan dalam mengelola data. Diharapkan, sistem ini dapat memberikan laporan persediaan barang yang cepat dan akurat, serta memberikan peringatan ketika stok suku cadang mencapai batas minimal, sehingga pelanggan tidak kecewa. Keamanan sistem juga terjamin dengan penggunaan kata sandi, dan basis data berbasis web memungkinkan setiap pengguna bekerja lebih efektif.
